8 recautions Before Use Be sure to read this entire catalog to make the proper chain selection for your application. In addition, be sure to indicate the relevant sections to the persons who will actually be maintaining the conveyor chain. is a convenient, compact mechanical device that can transport goods and materials while taking up a minimal amount of space. owever, it does not have an unlimited service life. 1Conveyor chain must be inspected on a regular basis and replaced as necessary. It is subject to wear and should be regarded as an expendable item. 5Environmental conditions, such as the presence of corrosive liquids or gases, may cause chain breakage. his can be avoided by selecting a chain material appropriate to the usage conditions. 2Elongation resulting from wear may cause conveyor chain to ride up on a sprocket or break. roper lubrication or the use of a lube free chain such as the Lambda Series can minimize chain elongation and extend service life. 6 Improper centering, or problems with layout or design, can shorten chain life or cause chain breakage. his can be avoided by proper positioning and alignment. 7Wear on chain parts will generate dust (wear dust). 3 Wear between the bushes and the rollers will cause interference between the link plates and guide rails, increasing tension on the chain. his may lead to an increase in motor power consumption, or may cause chain breakage. his situation can be avoided by proper lubrication or by using Lambda Chain or plastic roller chain. 4Excessive tension may cause chain breakage. his can be avoided through proper selection that anticipates the inertial force the chain will be subject to. 8When restrictions by law or guidelines exist in selecting chain, select the chain based on those laws and guidelines, and on allowable tension. Choose a chain with an ample margin. 9When link plate holes are enlarged or pin diameter made smaller to make it easier to insert and remove the pin, chain performance may decrease and cause accidents. 7

9 Features and Important oints of Conveyor Chains Features 1Can move conveyed goods or materials with almost any shape or form. 2. Wide operational range, including conveyor length, transport direction, usage environment, etc. 3. Can reliably convey goods or materials with no slippage. 4. ighly durable, highly efficient. Important oints 1. o slippage is a strong advantage of conveyor chain, but consideration must be given in selection when impact resistance is considered. 2. he mechanical nature of the chain engaging the sprocket will cause speed variations. andling recautions 1Mishandling the chain may cause a loss of accuracy. ever handle the chain as shown in the photographs to the right. 2. Rough handling such as throwing or dropping the chain will cause twisting deformation and/or a loss of accuracy. 3. Stainless steel chain, in particular, must be handled with care. Chain andling old the chain so that it does not become tangled or twisted. andling the chain in such a way that it becomes tangled or looped around itself will cause it to become twisted and lead to a loss of accuracy. pplying excessive load in the direction that the chain is twisted will cause torsion and lead to a loss of accuracy. 8

10 Construction Double itch Double itch Chain Construction Double itch Roller Chain has the same basic construction as standard roller chain, but chain pitch is twice as long, and the chain has flat-shaped link plates with longer attachments. R rollers and S rollers are available, with usage depending on application. (See Roller ype on page 11.) Can be used with double pitch sprockets or Roller Chain sprockets (with S rollers, when the number of sprocket teeth is 30 or more). Ideal for applications where the conveying distance is relatively long or the speed is low. ress Fit Outer Link with ttachment in ress Fit Bush Inner Link with ttachment Roller ress Fit Offset in Slip Fit ress Fit Inner late Bush Slip Fit Slip Fit Cotter in Roller Outer late Connecting late Slip Fit Spring Clip Offset Link Connecting Link Base Chain 1. late 3. Bush 9 he plate bears the tension placed on the chain. Because the accuracy of the holes into which pins or bushes are fit affects chain quality, plates are manufactured with particular precision and finished into tough plates with high fatigue strength and impact resistance. 2. in he two ends of the pin are inserted into holes in the outer plates and riveted in place. For ollow in Chain and oly Steel Chain, they are inserted only. Because the pins are subject to shearing and bending forces via the plates, and because the bushes rotate and slide along the pins as the chain articulates, they are manufactured with an emphasis on strength and abrasion resistance. he two ends of the bushes are inserted into the inner plate and function as bearings for the pins and rollers. hey are subject to complex forces through the various parts, and are finished to specifications having high wear resistance. 4. Roller Rollers are slip fit onto the bushes, and lighten mechanical shock when the chain engages the sprocket. In addition, they serve to reduce running resistance by turning while the chain is in motion, making the chain run smoothly. brasion resistance is important. 5. ttachment Bolt holes are drilled for attachments. (For details, see page 12: ttachments.)

11 ttachment Chain Construction his chain is a standard Roller Chain with added attachments. Because the chain pitch is smaller, it can transport small objects using the small pitch, and is ideal for general applications where conveying distance is short. Runs quietly, smoothly and can travel at high speeds. Roller Chain sprockets can be used in almost all cases. ress Fit in ress Fit Outer Link with ttachment Inner Link with ttachment Bush Offset in Roller ress Fit ress Fit Slip Fit Bush Roller Inner late Slip Fit Outer late Slip Fit Cotter in Slip Fit Connecting late Spring Clip Offset Link Connecting Link Base Chain 6.

Inner Link he ends of the two bushes are inserted into the inner plate to form the inner link. Rollers are slip fit over the outside of the bushes. 8. Outer Link he ends of the two pins are inserted into the outer plate. he ends of the pins other than those on the connecting links are riveted in place to prevent detachment. For ollow in Chain and oly Steel Chain, they are inserted only. he pitch, roller diameter, and inner width of the inner link are considered the basic three dimensions of a roller chain. When these dimensions are identical, a roller chain and sprocket are dimensionally compatible. ote: Slip Fit When the shafts and holes are fitted together, there is a continuous loose fit. his is a fit where the range of tolerance for the hole is larger than the range of tolerance for the shaft (pin or bush). ress Fit When the shafts and holes are fitted together, there is a continuous interferential fit. his is a fit where the range of tolerance for the hole is smaller than the range of tolerance for the shaft (pin or bush). 10

12 Connecting arts 1. Connecting Links (symbol: CL) 1 chain normally consists of multiple interconnected links and so requires a connecting link. 2 Connecting links are available with attachments or without attachments. 3 Connecting links are available with either spring clips or cotter pins to prevent the connecting plate from detaching.

16 ow to Order When ordering small size conveyor chain, specify chain size and material as well as chain length and the installation position and configuration of attachments. 1. Model Identification o prevent errors, specify the product code and model number for chain, connecting links, and offset links. For product codes and model identification, see the model identification examples on page 16 and dimension tables. lso, use only the model number for ordering products that have no product code. 2. Specific Ordering rocedure for Chain 1) Units (stock items) [1 unit = 10 ft/3,048 mm] (1) Small size conveyor chain with attachments is stocked in units (standard length). Each unit consists of an even number of links (the number of links is per the dimension table.) (2) connecting link is supplied on one end of each chain unit and an inner link is supplied on the other end. In general, these terminating links can be joined together to make a longer chain. (3) When splitting a single unit for use, order the required number of connecting links separately. Example: RF2040R-4L2.. n units RF CL.. n pieces ote: For 25, 1 unit = 1,000 mm 2) ssembly for Made-to-Order roduct chain assembled to your specifications based on chain length, termination on both ends, attachment spacing, etc., is called a special assembly. ow to specify the formation is described below. (1) When otal Length Is an Even umber of Links (1) connecting link is supplied on one end of each chain unit and an inner link is supplied on the other end. (2) Specify the adding position and spacing for attachments according to 4. ttachment Spacingand Description on page 17. (3) lease contact a subakimoto representative for special chain lengths. (2) When otal Length Is an Odd umber of Links (please refer to the pictures below) (1) Specify how both ends will be terminated: a) Inner links on both ends b) Connecting links on both ends c) Outer links on both ends (shipped with the outer links disassembled; after assembling the outer links on both ends, the end surfaces of the pins must be properly secured by riveting) d) Connecting link on one end and offset link on other end (2) Specify the adding position and spacing for attachments according to 4. ttachment Spacing and Description on page 17. (3) lease contact a subakimoto representative for special chain lengths. (3) When Chains re to Be Used as Strands (1) Mirror-Image Strands in airs ttachments on a set of chains to be used as strands are manufactured to be symmetrical (see illustration below). [1 unit = 10 ft/3,048 mm] Specification example: RF2040S-6L1-5L E.. 6 units Strand specs: 120 links by 6 strands (120 links x 2 strands x 3 sets) Mirror-Image Strands in airs ttachments are mirror images on opposite strands For E, 1, KK1, S1, SKK1, and GK1 attachments, instructions for half-assembly in mirror image are unnecessary when using chains in parallel (symmetrical on right and left sides). (2) Matched and agged in airs Chain lengths will vary within standard tolerance. When it is desirable to minimize the relative difference in total chain length in a set of chains to be used as strands, the chain is matched and tagged in pairs. [1 unit = 10 ft/3,048 mm] Specification example: RF2040R-2L2.. 6 units Strand specs: 2 strands x 3 sets Matched and tagged in pairs ote: here is an extra charge for chains matched and tagged in pairs. lease inquire for an estimate. (4) Long Chain Lengths (long configurations) Chains consisting of more than one unit are called long chains. here are limitations on total chain length depending on chain size and conveyor type. lease inquire for details. 3. Configurations When Ordering by otal umber of Links 1) For Long Configurations, Be Sure to Specify [see 2-(4) above] 2) When Unspecified: (1) We will ship n units, plus one unit having a fractional number of links. owever, when the fractional number of links is less than one-fourth of a unit, we will ship only one long configuration chain consisting of one unit plus a fractional number of links. Example: RF2040R-2L links Shipping form: 120 links (length of one unit).. 2 strands 140 links.. 1 strand a b (2) When a single unit cannot be split at an interval between attachments, we will determine a configuration (length) using a number of links that enable the chain to be split in the range of (1 unit 1/4 unit). he fractional number of links will be treated in the same way as above. c d 15

Conveyor rrangement (able 8) ake-up Guide Roller, Idler Drive Shaft Smooth operation and vibrations are small. ower required is low since frictional resistance is small. Center distance between sprockets should be generally over 10 m. pplicable for speeds over 20 m/min. Center distance between sprockets should be generally less than 10 m. pplicable for speeds under 20 m/min. Resistant to loading shocks and bad environments; however, the rail damages quickly. Construction is simple. ower required is large. Both the conveying and return sides are supported by rails. he most recommended and streamlined layout. sag is produced on the take-off side of the sprocket. he return side is supported by guides, rollers, or idlers. Since the chain bends when it comes into contact with the rollers or guides, an increase in friction occurs, allowing for easy wear. lso, vibrations of the chain exert a bad effect on overall running. Consequently it is not desirable to have a long center distance between sprockets. he return side is not supported. he tension due to the mass of the chain on the return side produces vibrations causing rough conveying. Examples showing slat conveyors and a cross rod conveyor that are most commonly used: he slat is installed using the attachment and the rollers roll over the rails on both the conveying and return sides. he slat is installed using the K attachment. In comparison to the above example, this type of arrangement is suitable for wide slat conveyors where the mass of the conveyed goods is heavy. owever, on the return side the slat slides on the rail. his is a cross rod conveyor where a pipe is installed by means of an E attachment, GK attachment, or ollow in Chain. he rollers roll on the rails on both the conveying and return sides. 3. Use of at igh/low emperatures s a general rule, standard small size conveyor chain can be operated in clean air environments and in ambient temperatures between -10 C and 60 C. When the chain is operated in environments outside this range, the following points should be taken into consideration. 1. Operation at very low or high temperatures: Chain must be selected or used in a different manner when it is operated in freezing chambers, cold areas, when it passes through dryers or heat-treatment furnaces, or when it is affected by heat from the material being conveyed. able 9 below provides guidelines for the relationship between allowable tension and temperature for standard chains. able 9: emperature Corrected Working Load emperature Range -30 C to -20 C -20 C to -10 C -10 C to 150 C 150 C to 200 C 200 C to 250 C llowable ension (Max. allowable load in catalog) x 0.25 (Max. allowable load in catalog) x 0.33 (Max. allowable load in catalog) x 1.0 (Max. allowable load in catalog) x 0.75 (Max. allowable load in catalog) x 0.5 able 10: emperature Environment and oints of Concern emperature Usage Conditions otential roblems Range -50 C to -30 C -30 C to -10 C 60 C to 150 C 150 C to 250 C 250 C to 400 C Under -30 C or lower conditions, corrosion-resistant SS and S stainless steel chains are suggested. steel chains cannot be used. steel chain should be selected on the basis of the corrected working load, above (able 9). lubrication is required. Because wear resistance is reduced in this temperature range, selection of the next larger pitch chain size over the one originally selected to reduce bearing pressures is suggested. When standard chain is to be used, evaluate whether or not the chain can be used at a reduced allowable tension (see able 9 above). Corrosion-resistant SS and S stainless steel chains are suggested. (1) Low-temperature embrittlement may occur on standard steel chain, reducing impact resistance. (2) Congealing of lubricant. (3) Rust due to condensation. (4) Seizure due to frost formation. (1) Excessive wear due to decrease of hardness of pin and bush. (2) Excessive elongation due to softening. (3) oor lubrication and chain seizure due to deterioration of lubricant. (4) Excessive wear and chain seizure due to formation of scale. 4. Lubricants and igh/low emperatures low-temperature or high-temperature lubricants are required if a chain will be exposed to temperatures outside the range of 10 C to 60 C.

96 Engineering Manual lus igh recision Conveyor Chain Engineering Manual 5. Cautions on Use in Environments s a general rule, conveyor chain should be used in clean air environments. When used in a special environment, reference should be made to the following items. 1. Use in Wet Conditions If the chain is splashed with water or goes through heated vapor, the following problems may occur. 1) Increase in wear elongation due to improper or insufficient lubrication. 2) Decrease in fatigue strength from rust and corrosion (pitting) of the chain. Countermeasures Reduce bearing pressure using a larger sized chain to improve wear resistance. Use corrosion-resistant small size conveyor chain for rust prevention. 2. Use in cidic or lkaline Conditions If the chain is exposed to acids or alkaline conditions, such as battery acid and liquid used in plating processes, the following problems may occur. 1) Embrittlement fracture of link plates and pins. 2) Fatigue breakage of link plates and pins due to rust and pitting corrosion. 3) Wear from usual mechanical abrasion and corrosion. 4) Reduction in volume of the whole chain from corrosion. 5) In special cases where the chain is underwater (immersed in liquid), electrochemical corrosion may occur. 6) here are also circumstances where even stainless steel chain will corrode. he photograph below shows an example of chain that was used in a plating apparatus. he chain fell to pieces within one month due to the effects of acid. Corrosion of Stainless Steel Drive Chain Countermeasures for Embrittlement Fractures (stress corrosion cracking) dopt a brittleness countermeasure that lowers crack susceptibility. Install a cover or casing to prevent acids or alkalis from contacting the chain. dopt a high-grade material with anti-corrosive properties. Countermeasures for Corrosion Use surface-treated attachment chain. Install a cover or casing to prevent acids or alkalis from contacting the chain. dopt a high-grade material with anti-corrosive properties. In general, embrittlement fractures (stress corrosion cracking) occur around the link plate holes. his is the area where the pin and bush are press-fitted to the link plate having the highest concentration of stress. Cracks occur even when there is no tension on the chain. Conveyor chain in general is more susceptible to acids than alkalis, and in special cases, embrittlement fractures (stress corrosion cracking) are generated by seawater or pit water. ydrogen Embrittlement Cracking 3. Use Under Conditions Where brasion Is a roblem If the chain is exposed to strong abrasive materials that promote wear such as sand, coke, and metal particles, the following problems may occur. 1) When abrasive materials penetrate between the pins and bushes, chain wear is promoted and poor articulation occurs. 2) When abrasive materials penetrate between the bushes and rollers, chain wear is promoted and poor roller rotation occurs. 3) When abrasive materials penetrate between the link plates, poor articulation occurs. Countermeasures pply a dust-protection casing. Remove foreign particles by regularly washing the chain. Reduce bearing pressure using a larger sized chain to improve wear resistance. dopt a chain that has specially processed parts where abrasion is a problem. 95

97 6. Other recautions 1) o keep long conveyors consistently operating in top condition, use take-up devices to eliminate chain slack. ake-up stroke = (center distance between sprockets X 0.02) + catenary sag allowance he 0.02 factor represents a 2% allowable wear elongation of chain. 2) Chain must always be engaged with at least three sprocket teeth. 3) When operating with multiple strands of conveyor chain, sprockets should be mounted on the same shaft and all sprocket teeth should be properly aligned. 4) When operating a long conveyor with two or more strands of chain, and when especially high pitch accuracy is required, subaki can provide specially configured chain to minimize the relative difference in length. lso, special sprockets can be manufactured to ensure that sprocket teeth are properly aligned. 7. Corrosion Resistance Guide for Corrosion Resistant Chains and Sprockets (able 11) Corrosion resistance varies accordingly depending on application conditions. his table should not be considered a guarantee.

Rails In general, rails wear faster than chain. While it is important that the rail material be matched to the chain material, in general, rolled steel for general structures (SS400) or plastic material (ultra-high molecular weight polyethylene) is recommended. 1) Wear is a complex phenomenon and is influenced by a variety of factors, including corrosion, lubrication, load speed, and operating time. Deducing the precise relationship between chain life and rail material is difficult. 2) Chain life is influenced by the rail. For new installations, verify the wear state by selecting rail material that is slightly softer than the chain. he smoother the finish on the rail surface, the better. 3) Operating conditions must be taken into consideration when selecting materials. In environments involving mechanical impact and other special conditions, there may be cases when plastic should not be used. 4) recautions before putting rails into operation 1. Lubricate all rail connecting parts, chamfer edges, and eliminate uneven levels and gaps. (See Figure 4.) 2. fter welding rail, remove sputter or scale. 3. During the trial run, run the conveyor unloaded. Lubricate the chain and check the condition of chain and rails. Rail Width W Rail width W is generally set to the sprocket facewidth.

Lock the sprockets that are installed and used on the same shaft so that the teeth of both sprockets align in terms of phase. 2. Centering Because the conveyor chain runs on a guide rail, the precision of the guide rail must be especially high and the conveyor properly centered. In cases like vertical bucket elevators where there are no guide rails, if the conveyor is not precisely centered, the chain will wobble and weave. his will have a significant impact on the life of the conveyor chain. Spaces are required to account for heat expansion of the rail. Figure 4: Rail Joints R Figure 5: Chain Entrance/Exit from Guide Rail W Large Gap o ensure that the chain moves smoothly, bend the guide rail to a radius of R at the points where the chain engages and disengages from the rail.

Grind down the riveted heads of the pins until they are level with the outer plate. Whichever method is used, support blocks should be placed under the chain on either side of the vise to ensure that the chain remains stable (Figure 10). ny attachment can be cut using this method. owever more force will be required to remove the pin as mentioned in 3. in Removal on the next page.

102 Engineering Manual Lubrication roper lubrication of roller chain is essential for peak performance and full chain life. In particular, the greater the level of performance demanded of the chain, the more the need for lubrication increases. 1) he purpose of lubrication is to reduce wear on chain parts, prevent corrosion (rust), and economize on power demands. 2) Lubricate the chain periodically (about once a week) so that the chain always remains damp with oil. erform drip lubrication (using lube listed below) or apply lube with a brush. 3) Lubrication locations Since wear between pins and bushes causes chain elongation, lubrication must be maintained on all contact surfaces. lso, areas where chain parts (plates, etc.) come into contact with guide rails must be lubricated (see Figure 26).

103 ension djustment he correct amount of chain slack is essential for proper operation of the chain. When the chain is too tight, working parts such as chain, sprocket wheel, shaft, bearings, etc., carry a much heavier load, accelerating chain wear. On the other hand, too much slack is also harmful and causes the chain to climb the sprocket teeth. 1. Frequency of djustment he chain has a tendency to stretch a certain amount at the beginning of operation due to slight distortion of its components. fter such initial elongation, the chain stretches slightly, but constantly, as a result of normal wear. o maintain proper chain tension, adjustments, if necessary, should be made at regular intervals. ssuming eight hours of operation a day, the frequency schedule for inspection and adjustment is given in the table below. When working hours are increased, the frequency of adjustment should be increased accordingly. eglect of careful inspection increases the chances of an accident. 2. Insufficient ake-up djustment If there is still excessive slack in the chain even after the take-up adjustment is fully tightened, shorten the chain by removing two links. See page 98, ow to Cut Chain for the steps involved. ake-up 1st week after start of operation 2nd to 4th week after start of operation hereafter Once a day wice a week wice a month Some Slack Drive 3. Even djustment of ake-up on Both Sides Where two parallel chains are adjusted by two independently operated take-ups, care must be taken to ensure even stroke on both the left and right side (not needed when the take-ups are cooperating screw type or counterweight type). n uneven adjustment will cause the link plate and the side of the sprocket teeth to interfere with each other and result in an overload condition. When the right and left sides are uneven, the two chains should be made even by replacing a portion of the right and left chains. lus he angle of wrap between the chain and drive sprocket should be at least 120, or the chain must always be engaged with at least three sprocket teeth. ake-up Figure 27: djusting Chain Slack Drive igh recision Conveyor Chain Engineering Manual 102

104 Engineering Manual rial Run fter installing the chain, carry out a trial run and check the following items before you actually start running the chain. lus igh recision Conveyor Chain Engineering Manual 1. Before rial Run 1) Connecting spring clips and cotter pins are installed correctly. 2) Chain slack is adjusted properly. 3) Lubrication is adequate. 4) he chain does not come into contact with casing or covers. Inspection Frequently inspect the chain during the initial operating period in order to carry out necessary adjustment. Inspect the following items. 1) Unusual wear of chain. 2) Slack in chain. 3) Vibration and jerking of chain. 4) Unusual wear of sprocket, unusual contact of sprocket with other components due to eccentricity, dust accumulated on root of teeth. When the sprocket properly engages with the chain, even contact is represented by the trace of contact shown as in the illustration, while uneven trace of contact as B in the illustration represents improper installation of the sprocket or a twisted chain. Rechecking is needed. roper contact should be traced a little above the root. owever, when initial tension remains in the slacked side of the chain, the chain slightly contacts Figure 28: race of Contact the root. owever, even in this case, strong contact should be traced around. In the case of idlers and tighteners, contact happens at the middle of the root. 5) oo much wear of guide rail. 6) ny abnormality in the lubricating system. 2. rial Run 1) here are no strange noises. 2) here is no excessive chain vibration. 3) he chain does not run up on the sprockets. 4) he chain is not jammed into the sprockets. 5) he rails and sprockets are installed correctly. 6) he rollers rotate smoothly. 7) here are no stiff areas during chain articulation. Caution n unloaded trial run should be conducted after installation by intermittently switching the system on and off several times. fter inspection, a continuous unloaded trial run should be conducted. rior to the trial run, be sure to lubricate the chain to allow lubricant to work into various components. Causes of Vibration, Jerking, and Unusual Wear 1) Overload, glass fragments caught between components. 2) Warping of the chain on the return side. 3) Insufficient lubrication or no lubrication. 4) Wear of the sprocket. 5) Unusual wear or breakage of the chain. 103

105 1. Chain Wear Elongation he chain should be measured by stretching it slightly to remove any backlash or looseness. Measure the distance of the inside (L1) and outside (L2) of rollers at both ends of the measured links to obtain measurement (L). When measuring, use at least 6 to 10 links to help keep any measuring error to a minimum. L1 L Measured length (L) length Chain wear elongation (%) = x 100% length length = Chain pitch X o. of links he chain should be replaced when wear elongation is greater than 2% of the chain pitch. chain wear measurement scale that allows easy checking of pitch stretch is available from subaki. For Lambda Chain, if the chain elongation reaches around 0.5%, then the oil has run out. Indicators of this condition are red wear dust between the plates and occurrence of poor chain articulation. In this situation the chain is no longer usable and should be replaced. 2. R Rollers When wear between the bush and roller causes the under surface of the link plate to contact the guide rail, the chain has usually reached the end of its usable service life. When the link plate starts contacting the guide rail, rolling contact suddenly turns into sliding contact between the link plate and rail, resulting in greater wear, an increase in chain tension, and a reduction in transmitted power. Usage Limits 3. S Rollers he chain has reached the end of its service life as soon as holes or cracks appear on the rollers due to wear. 4. Link lates For conveyor configurations in which link plates move directly on the material to be conveyed or on a guide rail, the service life has come to an end when the worn section equals /8, as shown in the drawing. Figure 30: late Width Wear 5. Sprockets When the sprocket is worn as illustrated below (to the left), the chain is prone to being caught by the tips of the teeth (), making the departure of the chain from the sprocket difficult, hence resulting in vibration of the chain. hough wear allowance depends on the type of conveyor and the size of the chain to a certain extent, if the sprocket is replaced when the wear reaches 0.3 to 1.0 mm, damage to the chain can be avoided. When the sprocket is worn in the direction of the facewidth as illustrated below (to the right), the shaft may not be properly aligned, therefore correct it. Wear Wear Figure 32: Wear of Sprocket eeth 1. Shutdown/Restart Stop the conveyor under no-load conditions to prevent remaining material from overloading the system when the conveyor starts again. lso, if the conveyor system has been shut down for a long period of time, be sure to inspect the chain before restarting. 2. Securing Conveyor arts arts fastened to the conveyor such as buckets, aprons, slats, etc., tend to loosen as a result of vibration. ay careful attention to fastening nuts and bolts, and check periodically that they are tightly fastened. 3. emperature and revention of Freezing Conveyor damage may occur when differences in temperatures (between day and night in winter) are extreme. Under these circumstances, operate the conveyor carefully, taking into account any variations in temperature as well as appropriate lubrication, the moisture content of the conveyed material, inspections, etc. 4. Spare Chain Storage In the unlikely event of a failure or accident, we recommend that a spare chain be prepared in advance. his spare chain should be stored in a dry space. lso, if the chain is to be stored for a long period of time, it should Other recautions be coated with a rust-preventive oil. For convenience, attach a tag noting the product name, model number, date of purchase, and equipment it is intended to be used on. 5. Record of Use and Maintenance Beyond the maintenance and inspection items mentioned above, after installing the conveyor, prepare a record of the expected capacity to be conveyed, conveying speed, r/min. of main shaft, electric current, voltage, power, working hours, actual conveying capacity, inspection dates, lubricating dates, details of problems, and the like. his will serve as protection against unexpected accidents. When updated on a regular basis, this record will also be convenient for maintenance and repairs. 6. Cleaning he chain should be cleaned periodically to remove contamination or particles of conveyed material from the chain and rail. 7. Storage of Chain and Sprockets Chain and sprockets should be stored in a place free of dust and dirt and where they will not be exposed to rain. o prevent rust, use a brush to coat sprockets with oil. o rust-prevention treatment is applied at the time chain is shipped. herefore, when storing chain, coat with a rustpreventative oil and inspect periodically for corrosion. lus igh recision Conveyor Chain Engineering Manual 104
