-
Determine operating conditions
Clarify transmitted torque, speed, working environment, and installation space
-
Calculate load
Determine the calculated torque Tc = K·Tn based on the characteristics of the prime mover and driven machine
-
Select series
Select the suitable series based on the connection type (flange/spline) and telescopic length
-
Confirm specification
Refer to the parameter table and select the smallest specification model that satisfies Tc ≤ Tn
-
Verify dynamic balancing
Verify according to ISO 1940 G6.3 grade; for high speeds, upgrade to G2.5
Notes
- During installation, ensure the misalignment between the two shafts is within the allowable range.
- Regularly check the lubrication status of the cross shaft bearings.
- The working angle must not exceed the rated deflection angle.
- In high-temperature environments, use high-temperature resistant grease.
