Selection and precautions of servo planetary reducer model

When choosing a servo planetary reducer model, you must first understand the reduction ratio and torque calculation, because these two parameters are very important.

The model selection of the servo planetary reducer is as close as possible to the ideal reduction ratio:

Ideal reduction ratio = servo motor speed ÷ reducer output shaft speed

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

Torque calculation formula: T=9550P/n

In addition, the applicable power is generally applicable to the servo planetary reducer on the market. The applicability of the reducer is extremely high, and the work coefficient can be maintained above 1.2, but it can also be determined according to your own needs when purchasing.

Selection points of servo planetary reducer model

1. The output shaft diameter of the selected servo motor shall not be larger than the maximum shaft diameter used in the table.

2. If the torque calculation works, the speed can meet the normal operation, but when the servo is fully output, if there is insufficient phenomenon, we can do current limiting control on the driver on the motor side, or do torque protection on the mechanical shaft. is very necessary.

The Selection of the servo planetary reducer includes the steps of proposing the original conditions, selecting the type, and determining the specifications.

In contrast, the type selection is relatively simple, and can provide accurate working conditions of the reducer. Mastering the design, manufacture and use characteristics of the reducer is the key to the correct and reasonable selection of specifications for the general reducer.

The specification selection of the servo planetary reducer should meet the conditions of strength, thermal balance, and radial load on the shaft extension.
