6 Large Size Conveyor Chain Overview recautions Before Use Always read this catalog and make the proper selection before using your Large Conveyor Chain. Ensure that all maintenance personnel are familiar with the related sections. Values given in this catalog are both in SI International Units and {Gravimetric Units}. Read the Following Before Use Caution he Large Conveyor Chain is a convenient part of machinery for compact conveyance, but this does not mean it has unlimited life. 1. he conveyor chain is an expendable item requiring periodic checks and replacement. 2. he conveyor chain may ride up on the sprocket or break from wear elongation. Lubrication will help extend the wear life of your chain. 4. Excessive tension may cause chain failure. Including inertial forces and other forces when making the proper selection can help avoid this problem. 6. oor centering and other layout problems can shorten the life of your chain, leading to chain failure. Installing equipment properly can help avoid this problem. 3. Wear between the bushings and the rollers may 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 cause chain failure. Avoid this problem with proper lubrication or by using bearing rollers. 5. Corrosion and other environmental factors can cause chain failure. Selecting material in light of usage conditions can help avoid this problem. 7. In situations where chain failure may pose a danger to human life or major damage to machinery, install the proper safety equipment to ensure against chain failure and potentially dangerous situations. 8. Select a chain based on any existing regulations based on rules or guidelines for chain selection and the safety factor. he chain selected should have an ample amount of both. rinciples for Rationalizing Conveyance 1. Minimize conveyance distance. 2. Maximize conveyor operating rate. 3. Select the appropriate chain. Selecting the optimal conveyor type is can tie directly into rationalizing conveyance. Read this catalog carefully to select the appropriate type of chain conveyor and rationalize your conveyance situation. 9. Widening plate holes, reducing the pin diameter,or heating the chain to make pin insertion and removal easier will remarkably decrease the performance of your chain and lead to accidents. Features and oints for Chain Conveyors Features 1. Can generally convey items of any shape or size. 2. Can increase applicable range of conveyor length, direction of conveyance, and usage conditions. 3. Conveys accurately with no slippage. 4. Can maintain a high endurance and efficiency. oints 1. While no slippage is a benefit, it is necessary to select chain in light of shock impact resistance. 2. Fluctuations in speed will result from the mechanical nature of chain and sprocket engagement.

7 Large Size Conveyor Chain Overview Construction he hree Basic Chain Dimensions he three basic dimensions of conveyor chain are pitch, roller diameter, and inner link inner width. When these dimensions are the same, the chain and sprocket are compatible. (1 pitch = 1 link) Overview 1. in (C) he most important role of the pin is connecting the inner link to the outer link. Along with the plate, it receives chain tension along the direction of travel while receiving vertical reactive forces from the conveyed items. he outer diameter of the pin suffers wear from sliding against the bush inner diameter when the chain articulates. he pin is an essential strength bearing part and requires high wear resistance. 2. Bush (B) he bush is a strength-bearing part, receiving tension from the chain during sprocket engagement, but its major role is as a bearing part. he outer diameter of the bush suffers wear from sliding against the roller inner diameter during roller rotation, while the bush inner diameter suffers wear from sliding against the outer diameter of the pin when the chain articulates. Bush inner diameter wear is directly expressible as pitch elongation. 3. Roller (R-R, F-R, S-R, M-R, -R) Forms a slip fit with the bush. Rotates when engaging with the sprocket, while alleviating the shock and wear from the teeth. Rotation also lowers running resistance. ote: ( ) denotes codes for part names as found on drawings. 4. late (L-A, L-B, BL) he plate mainly receives the tensile load along the chain's direction of travel while receiving vertical reactive forces while supporting the conveyed item. he outer plate and inner plate slide against each other during chain articulation, as well as against the sides of the sprocket teeth during sprocket engagement. late holes are either round or flat. 5. Attachments For attaching items to the chain. 6. -pin After the outer plate is press-fitted to the pin, a -pin is inserted and bent to prevent the pin from falling out. 30 or more Bend 30 or more, or so that the end of the -pin does not exceed the height of the plate. For Safety ever weld additional parts onto an assembled chain. Doing so may cause chain kinking or twisting due to plate deformation, further reducing part hardness and leading to embrittlement fracture from the welding heat.

8 Large Size Conveyor Chain Overview Roller ypes subaki Conveyor Chains use three basic roller types. 1. R Rollers subaki's most basic, versatile roller type. It has a large allowable load and low frictional resistance. R Roller he outer diameter of the roller is larger than the height of the link plate. 2. F Rollers Flange rollers are a simple way to prevent side oscillation. hey are perfect for rough usage conditions and regular slat conveyance. Be careful when using K attachments, as the attachment area may contact the roller flange. F Roller Flange here is a flange on the roller, attached on the -pin side, that acts as a guide. -pin 3. S, M, and Rollers hese rollers are effective in alleviating the shock and wear the chain would normally suffer during sprocket engagement. S Rollers : he outer diameter of the roller is smaller than the height of the link plate. M Rollers : he outer diameter of the M Roller is slightly larger than that of the S Roller. Rollers : he roller diameter of the M and rollers are the same, but the pin diameter is larger, increasing its strength. (RF26200 and above) S, M, Roller Other roller types Bearing Rollers subaki Bearing Roller Conveyor Chain, with its unique cylindrical bearings in the rollers, is able to provide longer wear life and suppression of stick-slip phenomenon, and reduce required power. R, F, and S roller types available. See pg. 51 for more information. 7

15 Large Size Conveyor Chain Overview Ordering Large Size Conveyor Chains 2. Specific Ordering Examples for Large Size Conveyor Chain Overview Unlike drive chains and light duty conveyor chains, large size conveyor chains are ordered in links instead of units. 2.1 Chain assembly when ordering with total number of links 1) In general, your large size conveyor chain will be delivered in standard lengths (~3m) + extra parts based on the total number of links in your order. Your chain may not be provided in standard lengths (~3m) depending on its size, pitch, or attachment spacing. lease notify us with any specific packing requests. Ex. 1) When ordering RF03100R-D-1LA2 500L (acking) 30L 16H + 20L 1H (total 500L) Ex. 2) When ordering RF03100R-D-1LA2 500L (250L 2H) (acking) 30L 16H + 10L 2H (total 500L) Ex. 3) When ordering RF03100R-D-4LA2 280L (standard length is not 3m) (acking) 28L 10H (total 280L) Caution Standard length will vary depending on chain size, pitch, and attachment spacing. We will try to deliver in ~3m standard lengths. Ex. 4) When ordering RF03100R-D-6LA2 38L (when quantity is indivisible due to attachment spacing) (acking) 30L x 1H + 8L x 1H (w/2 att.) (total 38L) 6 links Caution Attachments can be attached to extra parts as well. lease indicate if attachments are not needed. ry to ensure that attachment spacing allows for a evenly divisible quantity. Ex. 5) When ordering RF03100R-D-A2 20L (special assembly: A2 att. every 9th link) Caution Count links from the left hand side, starting at one. Instructions to start counting from the right may lead to incorrect attachment positioning. 2) One end of a standard length (~3m) will be the outer link, while the other end with be the inner link. Add addition chain lengths onto this standard length to create a longer chain. he connecting link is delivered with a loose press fit. (See photo below.) he pin of the connecting link is loosely press fitted. -pin ote: Delivery of the chain may differ depending on chain shape. 2.2 Special assembly A chain assembled to your specified chain length, end formation, attachment spacing, etc. is considered a special assembly When total length has an even number of links 1) One end of the chain will be the outer link, while the other end the inner link. 2) Refer to section Attachment Spacing for specifying the position and spacing of attachments When total length has an odd number of links a) Both ends inner links (RL RL) b) Both ends outer links (L L) c) One end outer link, other end offset link (L OL) Caution When using an odd number of links, be sure to specify the end formation as per a) c) above. C) requires a separate fee for an offset link. 14

16 Large Size Conveyor Chain Overview Ordering Large Size Conveyor Chains When using chain in parallel 1) Half assembled in mirror image Attachments on a set of chains to be used in parallel are manufactured to be Ex. RF03100R-6LA2-5LE1 symmetrical. hus, when chains need to be in mirror image, please specify half assembled in mirror image when ordering. Ordering strands in parallel does not mean that they will be in mirror image. he following examples show when half assembled in mirror image is appropriate and when it is not. Ex. 1) When ordering RF03100R-D-3LA2 68L (when not indicating half assembled in mirror image) Shipped as A: 30 L x 2H, B: 2L x 1H (w/3 att.) A 2 strands B 1 strand Caution When ordering chain, we will assume that the chains will be used in single strands (and not in parallel). lease indicate when two or more strands will be used, or when half assembled in mirror image is required. Ex. 2) RF03100R-D-3LA2 68L (when ordering half assembled in mirror image) Shipped as A: 30L x 1 strand, B: 4L x 1 strand (w/2 att.) as per the diagram A: 30L x 1 strand, B: 4L x 1H (w/2 att.) mirror image of diagram A 1 strand B 1 strand A 1 strand B 1 strand Caution We will only manufacture chains as per Ex. 2 when instructed to half assemble in mirror image. Ex. 3) RF03100R-D-3LA2 68L (34L x 2H) (when not indicating half assembled in mirror image) Shipped as A: 30L x 2H, B: 4L x 2H (w/2 att.) A 2 strands B 2 strands Caution We will arrange the number of links so that there are two strands, but it will not be manufactured as half assembled in mirror image. here are applications where not manufacturing half assembled in mirror image will result in problems. 2) Matched and tagged in pairs 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 in parallel, the chain is matched and tagged in pairs. Indicate one of the following two methods when ordering. Contact a subaki representative for details. ote: otal large size conveyor chain length tolerance is ±0.25%. Chains half assembled in mirror image cannot be matched and tagged in pairs. Only when stands are not interchangeable. 1) When ordering minimal matched tolerance differences he overall length of several sets of standard length (~3m) is measured, and without performing the match and tag process we will assemble the chain randomly based on the results of statistical and technical data. If the results are not appropriate, we will measure the total length of all strands and assemble. 2) When ordering matched and tagged within XX mm otal length of each standard length (~3m) is measured and assembled within the relative difference specified. Delivery Different colored tags are attached to the left and right sides at fixed intervals (~3m). Connecting order for the chain is written on the tag. ote: here is an extra charge for chains matched and tagged in pairs. Contact a subaki representative for details Long chain lengths Long chain lengths refer to chains with total lengths over a standard length (~3m). here are limits on long chain lengths depending on chain size due to transportation and handling problems. Contact a subaki representative for details Rust prevention Large Size Conveyor Chains are not coated with a rust preventative oil during shipping. lease indicate whether rust preventative measures are required when ordering. ote: A separate treatment fee will apply. 15

49 Large Size Conveyor Chain Sprockets Special Sprockets Sprocket teeth wear has a major impact on conveyor chain life. When sprocket teeth wear, it is necessary to replace the worn areas of the teeth or the whole sprocket. Both of these involve massive maintenance and replacement costs. Further, when the tooth wall is worn away it makes maintaining and managing tooth profile precision difficult, which can shorten the life of the chain. subaki manufactures a variety of sprockets that can help you reduce your sprocket maintenance and replacement costs. Replaceable tooth insert sprockets hanks to a deep quench hardened layer using unique subaki knowhow, these replaceable tooth insert sprockets are highly wear resistant, keeping wear to a minimum. Any worn teeth can be pulled from the sprocket and replaced individually for added convenience. Any worn teeth can be pulled from the sprocket and replaced individually ooth insert General Use/Heavy Duty/ Corrosion Resistant hermally sprayed replaceable tooth insert sprocket In addition to the features of regular replaceable tooth inserts, these inserts are thermally sprayed using the same technique for our longlasting FA Series conveyor chain for even greater wear resistance. est results show that they have over twice the life of non-thermally sprayed replaceable tooth inserts. ooth insert Split sprockets he sprocket itself can be split, allowing it to be easily mounted and removed from the shaft or replaced as a whole. We can also provide ringtooth type split sprockets where the section around the shaft remains the same while just the teeth are split. Sprockets with shaft subaki can also deliver sprockets with the shaft attached, saving you from troublesome assembly work. 48

50 Special Sprockets Hunting ooth (Double Duty) Sprockets hese sprockets have an odd number of teeth (7.5, 12.5, etc.) and are half the pitch of the chain. Every time the sprocket makes one revolution, the chain engages with one set of teeth, ahead of the previously engaged set. Ideal for when there are severe wear conditions acting on the teeth.

113 Large Size Conveyor Chain Related roducts oughroller (Endless-type Roller) Outstanding performance when conveying, transferring, or moving heavy items. Consisting of a frame and endless rollers, the endless rollers (roller, pin, and link plates) wrap around a center plate on the frame. In contrast to a standard bearing, the operating principle behind oughroller's operation is that the center plate is the inner ring, the rollers are the balls, the link plates and pins are the ball cage, and the contact surface is the outer ring. Construction op late Applications 1. ransferring/conveying heavy items. 2. When items are conveyed only infrequently and do not warrant conveyor use. 3. When efficient use of space is important. 4.

118 Large Size Conveyor Chain Related roducts oughroller (Endless-type Roller) otes on Handling 1. Standard oughrollers cannot take thrust loads along the roller axis. If thrust loads are present, consider using the optional side guide roller and skirt, or have a rail bear the thrust load. 6. Ensure a gradient of less than mm when there is a step in rail connections. he rail seams should be smooth or like as shown on the right. Side surface Upper surface Between 1 2mm 2. Except for double roller types, do not change directions while oughroller is in motion, as this will cause a thrust load as described in 1. above. Jack up the oughroller or use other means to change direction. 3. When using in corrosive environments (outdoors, in the rain, etc.) wash the unit and lubricate the entire chain with SAE30 40 oil each time. subaki offers stainless steel specifications for use in extremely corrosive environments. Use in high temperatures will accelerate lube deterioration. Always lube regularly. 4. Usage limits are when any of the following begins to occur: Center plates touch link plates Link plates touch rails Side plates touch rails Ensure there are no severe impacts on the rollers 7. oughrollers do not have a stopping mechanism. When leaving a oughroller in a stopped position, insert chocks between the side plates and rail. 8. When using a oughroller with a turntable, the manner shown in the drawing on the right is ideal. Attaching a bar between two rear oughrollers will allow for smooth travel. Rail Chock Handle Bar 5. Ensure there is no slippage between conveyed material and the oughroller. subaki offers oughrollers with rubber pads and spikes for this purpose. See 7. and 8. on pg Slippage With rubber pad or spikes 9. After use, remove dust and the like with a brush and apply a coat of lube or grease before storing. roduct umbering Example UF - Size (UF-J for junior types) Unit Roller types Steel rollers: o code lastic rollers: Double rollers: W oughroller (with endless rollers) Ordering Example Attachment Extended side plates: ES Handle: HDL urntable: B Lateral guide roller: SGR (One side: SGR-1, both sides: SGR-2) Spikes: SK Skirts: SK (One side: SK-1, both sides: SK-2) Rubber pad: GD Scrapers: SCR ote: Refer to individual sections for possible model (size/roller type) and attachment assemblies.

Application ex: Concrete floors otes on Use 1) Allowable load values are determined by roller-rail wheel contact pressure or bearing rotation strength. Use rails with SS400 or stronger material. Do not use bearing rollers with curved rails. 2) For lubed specifications, lack of lubrication will cause poor rotation. Use non-lubed or water resistant specifications in environments where bearing roller may come in contact with water. 3) Be aware that precision is much coarser than with cam followers. 4)Do not use in acidic or alkaline environments. Water resistant specifications (SUS400 Series parts) may rust in certain usage environments. 5) Due to the small clearance between axle and hole, do not chamfer the attachment hole for Axle Bearing Rollers. Be sure not to exceed the maximum screw tightening torque when attaching the nut. 6) Do not allow roller to come into contact with severe shock 7) his product does not come equipped with a brake. Consider installing one on the equipment side. 8) When re-lubricating lubed specifications, be sure to drip a few drops at a time between the roller and spacer on either side. Once lubrication has degraded, lube every 1-3 months with ISO VG {SAE30-40} oil. 9) Rotational resistance of bearings and spacers will increase if worn. Be sure to replace as necessary. Use the following to determine usage limit. Over 0.5mm of play between roller and bearing. When resin spacer has worn away. 10) All parts are coated with an anti-rust agent before shipment. 123

Ensure a safe working area for this purpose. he pump should be installed where there is minimal lateral chain vibration or vertical movement, where it will be easy to install, and where it will be parallel to the ground. Attach pump (nozzle) on the chain's return side (slack side) near the sprocket to ensure maximum penetration of lubricant between pin and bush and bush and roller. (See diagram below.) Install oil tank 300mm or higher than the pump. Install the oil tank parallel to the ground and 300mm or higher than the pump. ump will not operate if chain is run backwards. his is done so that the checker arm does not suffer any damage. (See diagram below.) Amount of lubrication necessary depends on chain size and usage conditions. 2 3 shots per spot is normal. Stop lubrication once the necessary amount of lubricant has been applied. (See diagram below.) Continuous operation will drastically hasten checker arm roller wear damage. Stopping lubrication using the oil tank plug while the pump is still in operation will drastically hasten wear damage on the pump and checker arm. Always stop lubrication with the checker arm. (See diagram below.) Be sure that the oil tank does not run out of lubrication. Operating the lubricator with no lubricant will drastically hasten wear damage on the pump. Once lubrication runs out air will enter the pump, requiring the air to be pumped out before lubrication can begin again. Lubrication will reduce wear on chain parts and reduce necessary power. Lubrication should generally take place more than once a week. Clean the chain first for effective lubrication. ump piston may lock when not in use for extended periods. Start lubricator up once a month to prevent locking. Accessories Stopping Lubrication Lubrication osition Safety Feature for Reverse Chain Running he roller of the checker arm will spring up when chain is run in reverse. (he spring will also automatically return it to position.) When stopping lubrication, always stop the conveyor first. ull the knob on top of the checker arm, tilt the arm 90 until it locks into the anchor hole. Once you are sure that it is not touching the conveyor chain, stop pump operation.

132 Selection and Handling 3. Deciding Chain ype When selecting conveyor chain type, it is necessary to identify the physical properties of the materials conveyed. Method of conveyance and chain conveyor type should then be determined, keeping cost performance in mind. hree basic types of conveyor are shown on pg. 95, which can be used for determining conveyor chain type. Key oints in Determining Conveyor Chain ype Adopt a loading type conveyor to reduce the running resistance of the conveyor chain when conveying materials, which will lead to energy savings. Bearing Roller Conveyor Chain and C Series are the most suitable for this application. Design layout so that powdery or liquid materials, or materials that will promote chain wear, are prevented from directly contacting the conveyor chain. Use a sealed conveyor, such as a flow conveyor, to prevent loose material from flying during conveyance. When using conveyor chains to convey very corrosive material, or in corrosive environments, select a conveyor chain with suitable specifications. (g. 108, Chart 13) 4. Deciding Roller ype Refer to "Roller ypes" in the pages concerning Large Conveyor Chain construction. See page Basic Conveyor Chain Layout 5.1 Horizontal Conveyor 2) o guide on the return side ake-up Drive For short center distance and slow chain speed. he mass of the chain on the return side may cause vibration, affecting chain operation. 3) Supporting the chain on the return side with guides or rollers ake-up ake-up Rollers supporting the return side Guide shoes supporting the return side Drive Drive Contact between chain and guide or roller may hasten chain wear or damage chain as it articulates at the roller or guide. his may also cause vibration, affecting chain operation. With a long center distance, it is practical to divide the return side into several catenaries. artial or full support by catenary on the return side (see diagrams above) can absorb chain elongation/shrinkage from heat or other factors. his arrangement can be used when chain speed is comparatively slow. Catenary sag should be about 10% of the free span. his is not recommended for reverse drives. 1) Making a catenary on the drive sprocket side C Drive 4) Supporting the entire return side Drive ake-up ake-up 1 Catenary tension makes chain-sprocket engagement smooth. 2 Lubrication at the catenary is most effective. he return side is entirely supported by rails, which are fixed on the take-up of the driven sprocket. his method absorbs all chain sag, and can also be used in reverse operation. However, there is no catenary on the drive sprocket lower side, making it necessary to regularly adjust chain elongation through take-up. Caution: Excessive tension from take-up will hasten chain wear. 131

133 Selection and Handling 5) Return side on top ake-up 5.2 Vertical Conveyors Drive Key oints in Using Conveyor Chains Lubricate chain to prevent elongation during use. Use a lubricant with an equivalent viscosity of ISO VG (SAE30-40). Use a drip or brush method and ensure lubricant penetrates between pins, bushes, rollers, and other areas to prevent metal-on-metal contact. (See pg. 124 for the subaki Automatic Conveyor Chain Lubricator.) If the conveyor will be stopped while loaded, it will be necessary to install a brake or subaki Back Stop Cam Clutch to prevent reverse operation. Caution: Excessive tension from take-up will hasten chain wear. Drive Ensure that sprocket shafts are parallel. At least three sprocket teeth need to engage the chain. Use take-up to adjust chain elongation. When using chains in parallel, be sure that sprocket teeth on both sides are aligned when engaging. ew chain will prematurely wear if connected to a sprocket whose teeth have severely worn. ake-up 5.3 Inclined Conveyors Drive ake-up 5.4 Vertical Shaft Conveyors Drive Selection and Handling ake-up Installing a guide roller will help the chain run smoother. 132

Chain itch and umber of Sprocket eeth 1) Smoother chain operation can be expected as the number of sprocket teeth increases. his means that for a sprocket with the same outer diameter, a shorter pitch chain can operate more smoothly due to a reduction in the polygonal speed fluctuation or less articulating angle of chain on the sprocket. his also results in less wear between pin and bush. 2) Longer pitch chain, though more expensive per link, would be cheaper for a unit length of chain in general. Chain pitch for Unit Conveyors is determined by unit size or attachment spacing. (Example) Attachment spacing = 2m * Chain pitch = 100, 200, 250 * Chain pitch can be selected by dividing attachment spacing by an even number. 3) he chain pitch for Bulk Conveyors is determined not only by material itself, but also by conveyor capacity. Conveyor capacity is determined by sizes of bucket, apron, scraper, etc. Chain pitch is in turn determined by these sizes. 4) Space limitation should also be kept in mind when selecting sprocket. 5) Chain pitch relates to the number of sprocket teeth and chain speed shown in able 2. able 2: Chain itch and Allowable Chain Speed Allowable Chain Speed (m/min) : o. of teeth Chain itch (mm) 133

147 Selection and Handling 3. est Operation erform a test operation after attaching the chain and before actual operation. Use the following checkpoints as a guide. 3.1 Before Beginning est Operation 1) Is the -pin on the connecting link properly attached? 2) Does the chain have the proper amount of catenary? 3) Does the chain have the proper amount of lubrication? 4) Does the chain hit the case or cover? 3.2 est Operation 1) Are there any abnormal noises? 2) Does the chain vibrate? 3) Does the chain ride up on the sprocket? 4) Does the chain wind up on the sprocket? 5) Are the rail(s) and sprocket(s) properly installed? 6) Are the rollers rotating smoothly? 7) Does the entire chain articulate smoothly? Caution: est operation after installation should consist of repeatedly starting and stopping the conveyor with no load, followed by continuous operation with no load. Lubricate chain before test operation so that parts wear in. 4. Adjusting Chain ension ake-up the chain to ensure proper operation of the conveyor. As a guide, chain should be adjusted pitches. he correct amount of slack is essential. Wear will advance on chains with too much tension, while chains with too much slack will ride up on the sprocket, causing accidents. 4.1 Chain Slack In a basic layout, a small amount of slack (δ) is needed on the return side as shown in the diagram below. oo much tension will promote chain wear, and too much slack will cause the chain to ride up on the sprocket teeth and cause damage. Drive Chain slack ( δ ) 0.1L Chain slack ake-up Drive Slack ake-up A slight amount of slack is needed. (A basic layout with a guide on the return side.) ake-up Slack Drive Drive 4.2 Frequency of Adjustment he chain will undergo initial elongation when first used, as well as elongation resulting from wear between pin and bush after operation. herefore, it is necessary to regularly adjust the chain through take-up to ensure proper chain tension. A chain operated for eight hours per day should be checked and adjusted as per the following chart. It becomes easier to neglect take-ups the longer the chain is used, which leads to chain catenary and accidents. hus, performing regular checks is essential. Within one week after initial operation Once/day Shorten interval between checks if chain speed is Within one month after initial operation wice/week fast or chain operating Over one month after initial operation wice/month time per day is over eight hours. 4.3 Adjustment Frequency When Chain Cannot Be Adjusted by ake-up Alone If there is still some slack in the chain, despite taking up the chain as much as possible, remove two (2) links from the chain and shorten the overall length. See our guide to connecting and disconnecting chain Even Adjustment of ake-up on Both Sides When 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 sides. For this, we will assume that the length of the left and right chains is roughly equal. herefore, it may be necessary to insert chain lengths at times to align the two lengths. (his is unnecessary with continuous or balance take-up.) An 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. Selection and Handling 146

Lubricate chain and inspect often while paying attention to temperature changes when conveying liquid items. Condensation may form when conveying high temperature items in a case conveyor. 6) Storing Extra Chain subaki recommends having extra chain on hand in the event of chain failure. Store extra chain indoors where there is low humidity. Apply an anti-rust oil when storing for extended periods. It may be convenient to attach a tag to the chain with the chain name, drawing number, date of purchase, equipment name, and other pertinent information. ooth surface wear Wear amount = 3 6 mm ooth side surface wear Wear amount= 0.2 2) subaki recommends replacing the sprocket when teeth are worn. Avoid flipping the sprocket over and continuing to use sprockets with worn teeth bottoms. When performing welding repairs, use a tooth gauge to check the tooth profile. 7) reventative Maintenance for the Conveyor In addition to the above maintenance and inspection, create a conveyor history log and periodically record conveyor capacity, conveyor speed, main shaft rotation speed, current, voltage, power, actual operating time, actual conveyance load, inspection/lubrication days, accidents, etc. his can help prevent unexpected accidents and facilitate repairs. 8) Cleaning eriodically clean chain and rail if in contact with foreign matter or conveyed items.
