Roller ChainInstallation & MaintenanceDrive Chain3) Correct the parallelism of the sprockets using a straight edge(or scale). Align the sprocket faces within the tolerancesshown below according to distance between sprockets.Up to 3.2 ft. + .04”3.2 ft. to 32 ft.:Over 32 ft.: + 0.4”Distance between shafts (ft.)122) When chain speed is fast and load fluctuates:The natural vibration frequency of roller chain and theshock cycle of pumping machinery, or chordal action (upand down movement) of roller chain may attune, causingthe roller chain to vibrate. In this case, a guide shoe(made of NBR or EPDM), etc. is used in order to stop theshaking and prevent vibration.3) When the center line is vertical:Install a tensioner that can automatically eliminate theextra chain slack. If the driving shaft is on the bottom, atensioner must be installed.Fig. 17 Alignment of sprockets4) Sprockets are fixed to shafts using Power Locks, LockSprockets, and keys (colors and bolt sets, etc. if required).4.5 Layouts ( used in the figures below denotes the driveside)1) General LayoutsWhen designing the roller chain drive, the centerline of bothsprockets should be close to horizontal. If installation is closeto vertical, it is desirable to install an idler or a guide shoebecause even slight elongation can cause the chain to comeoff the sprocket. The angle of inclination should be kept within60°.Fig. 21 Vibration preventive guide shoe4.6 Installation of Lambda Curved Chain1)Guide InstallationLambda Curved Chain has a greater degree of freedom withregard to the clearance between the pins and bushingscompared to standard chain. Therefore, a chain guide shouldbe installed to ensure that the chain directly engages with thesprocket.Fig. 18 General layouts2) Layouts Requiring Attention1) When the slack is on top:When the center distance is short, move the shafts toadjust the center distance of the sprockets until the chainfeels tight.Fig. 22 Vertical drives2) Minimum Radius (r)The R dimension of the guide should be greater than theminimum radii shown in the following table.Fig. 19 Layout when the center distance is shortIllustration of guideWhen the center distance is long, chain slack is adjustedby installing an idler, which supports the roller chain.RSC40CU-LambdaRSC50CU-LambdaRSC60CU-LambdaMinimum Radius (r)15.75”19.70”23.60”A-112Fig.20 Layout when center distance is long.
Roller ChainInstallation & Maintenance5. Chain Test RunAfter installing the chain, carry out a test run and check the following items before you actually start running the chain.5.1 Pre-Test Run1) Connecting link plates, clips, and cotter pins are installed correctly.2) Chain slack has been properly adjusted.3) Adequate lubrication is available.4) The chain isn’t touching any objects, such as chain cases, etc.5) There are no obstacles in the chain operating area, and all is clean.5.2 Test-Run1) Sound. There should be no strange noises. Make sure the chain doesn’t touch the case.2) Vibration. Look for excessive chain vibration.3) Sprocket-chain interaction. Make sure the chain doesn’t climb over the sprockets.4) Sprockets. Ensure that the chain separates smoothly from the sprocket.5) Chain articulation. The chain should articulate smoothly.Drive ChainIf you notice any of these conditions, do not begin operation. Correct any problems before proceeding any further.6. Roller Chain Inspection1) Roller chain needs to be replaced when parts are damaged or when there has been 1.5% wear elongation. Try to replacethe chain before this kind of situation occurs.2) If roller chain selection and operating conditions are suitable, you can expect long life and low chain maintenance.Eventually the pins and bushings will wear; and the chain will need to be replaced. Listed below is an inspection check list.6.1 Inspection ChecklistTable 3ProceduresStep IStep IIStep IIIMethodVisually check the chainduring operation and lookfor any abnormalities.Stop the chain andcarefully inspect each partof the chain and sprocket.In order to investigate inmore detail, remove theroller chain and inspect itvisually or check it withmeasuring instruments.Inspection Items1. Sound. There should be no strange noises.2. Vibration. Look for excessive chain vibration.3. Sprocket-chain interaction. Make sure the chain doesn’t climb over thesprockets.4. The chain isn’t jammed in the sprockets.5. There are no stiff areas during articulation.6. Adequate lubrication is available (lubricating system and quantity of oil)7. Make sure the chain doesn’t touch the case.1. Check the external cleanliness, corrosive, and lubrication conditions;also look for scratches or other damage to the link plate side and edgesurfaces, pin edges, and roller surfaces.2. Inspect for pin rotation and the clearance between the link plate and thepins.3. Inspect the sprocket teeth surfaces and teeth side surfaces forscratches or marks.4. Measure the wear elongation of the chain.5. Check the articulation of the chain and rotation of the rollers.6. When using a terminating device for lift applications, inspect the wear ofthe end bolts and the wear of the connecting link plate pins. Also checkfor proper installation at the same time.1. The inspection items are identical to those in Step II, however,everything is checked in more detail.Reference page fordetailsInspection pointsare on thefollowing pagesand on thetroubleshootingand problemsolvingpagesA-113
