Required information for roller chain selection
- 1) Machine to be used
- 2) Type of impact
- 3) Motor type
- 4) Rated power of motor
- 5) Bore diameter of high-speed shaft and RPM
- 6) Bore diameter of low-speed shaft and RPM
- 7) Distance between shafts
Motor characteristics required for chain selection
When using the allowable load selection method or the pin gear drive selection method, check the following characteristics of the motor.
- 1) Moment of inertia of motor
- 2) Rated torque of motor, or motor shaft RPM
- 3) Starting torque of motor
- 4) Maximum (stalling) torque of motor
- 5) Motor braking torque
⚠ Precautions when selecting roller chain
The roller chain selection conditions provided here are only applicable to the selection of roller chain model and size. Environmental deterioration including corrosion, aging, and the like, is not taken into account.
When guidelines or legal considerations impose constraints on the selection of roller chain, first make a selection based on these constraints and then make another selection based on the method specified by our company. Then choose the roller chain that provides the greater margin of safety. Ancillary equipment such as safety devices and lubrication devices should be selected separately.
