DRIVE CHAINS - Tsubaki

Selecting a Roller Chain8. Chain tension when motoraccelerates: FsItem SI units Gravimetric unitsChain tension when motordecelerates: Fb9. Design kW (for general selection)10. Design chain tensionDesign chain tension frommotor: F’mDesign chain tension fromstarting torque: F’msDesign chain tension fromstalling torque: F’mbDesign chain tension fromshuttle drive: F’cDesign chain tension duringacceleration: F’sDesign chain tension duringdeceleration: F’bDesign chain tension fromload: F’w11. Acceleration time of motor: ts12. Deceleration time of motor: tb13. Inertia ratio: R14. Conversion of the flywheel effect (GD 2 )to moment of inertia ( I ) Design kW = Rated kW of motor x Ks (kW) Or If the mass M (weight W) is not known, use the rated torque Tn of the motor tocalculate the shaft torque T = Tn x i kNÆm {kgfÆm}, and use F = 2T/d in place of W. All chain tensions in the above formulae are the tensions when one strand of chain is used.When using two or more strands of chain, calculate the chain tension for one strand and multiply it by the imbalanceload factor Ku (Table 4) for the number of strands used.Before Use For Safe Use Standard Roller Chains Lube-Free Roller Chains Heavy Duty Roller Chains Corrosion Resistant Roller Chains Specialty Roller Chains Accessories Selection Handling138
