DRIVE CHAINS - Tsubaki

Before Use For Safe UseStandard Roller Chains Lube-Free Roller Chains Heavy Duty Roller Chains Corrosion Resistant Roller Chains Specialty Roller Chains Accessories Selection HandlingUse bolts with the strength class 8.8 or higher (JIS1051-2000 Tensile strength 800 N/mm 2 or higher). (SCM435 heat treatedbolts, etc.)The length of the chain should be the travel distance plus .: The distance of overrun based on usage conditions.2) When used linearly (rack) with rollers facing down:Roller4) When wrapped partially or totally around the inside of a drum:Consult Tsubaki.See section 3).Dial gaugeConsult Tsubaki for internal fits.K1 attachment every 2 nd linkSK1 attachment every 2 nd linkAttach K1 or SK1 attachments every 2 nd link and fasten with bolts and nuts every 2 nd or 4 th link with chain pulled taut sothere is no slack or meandering.3) When wrapped partially or totally around the outside of a drum:5) When used for lateral wrapping (horizontal drive)6) Sprocket attachmentAttachment chain length is in the range of -0.05 to 0.15% of standard length(nominal pitch x number of links). When the chain is wrapped around a drum,shims need to be used between the drum and the chain attachments toeliminate slack.Since K attachments can be adjusted with shims, they can be attached ontothe drum more easily than SK attachments.When the drum is not perfectly round, the thickness of the shims needs to beadjusted while the chain is wrapped around the drum so the radius is circular.As shown below, a dial gauge or a surface gauge can be used for adjustment.Process tap holes to fit the holes of the chain attachments.Adjust the shaft of the sprocket so that the sprocket engages the chain straight.The clearance () between the rollers and the bottom of the sprocket teeth should be less than the dimensions shownin the following table. The bottom of the teeth and rollers should not touch each other.Chain sizeRS80 or lessRS100 to RS180RS200 or more1.0mm1.5mm2.0mm151When the bottom of the teeth and rollers touch each other in the clearance described above, the tooth form needs to bepre-designed with larger clearance .
