Model selection for planetary gearbox for concrete mixer:

Closely using the ideal reduction ratio.

Reduction ratio = servo motor speed / reducer output shaft speed

Torque calculation: Torque calculation is very important for the life of reducer, and pay attention to whether the maximum torque value (TP) of acceleration exceeds the maximum load torque of the reducer.

The applicable power is usually the applicable power of the servo models on the market, the applicability of the reducer is very high, the working coefficient can be maintained above 1.2, but the choice can also be based on their own needs to decide.China supplier planetary gear reducer for marine.
