Try to choose as close to the ideal reduction ratio as possible:
Reduction ratio = speed of servo motor / speed of output shaft of reducer
For the life of the reducer, the calculation of torque is very important, and pay attention to whether the maximum torque value (TP) of the acceleration exceeds the maximum load torque of the reducer.
Applicable power is usually the applicable power of the servo models on the market.The applicability of the reducer is very high, and the working coefficient can be maintained above 1.2.
There are two main points:
A. The output shaft diameter of the selected servo motor cannot be larger than the maximum used shaft diameter on the table.
B. If the torque calculation works, the rotation speed can meet the normal operation, but when the servo is full output, if there is a shortage, we can do current limiting control on the motor side drive, or torque protection on the mechanical shaft. Is necessary.
The selection of universal reducer includes the steps of proposing original conditions, selecting types, and determining specifications.
In contrast, the type selection is relatively simple, and accurately provides the working conditions of the reducer. Mastering the design, manufacturing and use characteristics of the reducer is the key to the correct and reasonable selection of the general reducer.
Specification should meet the conditions of strength, thermal balance, and radial load on the shaft extension
