Installation method of planetary precision reducer

2021-10-11

The correct installation, use and maintenance of the reducer is an important part of ensuring the normal operation of the mechanical equipment. Therefore, when you install the planetary precision reducer, please be sure to install it carefully in strict accordance with the following installation sequence.

Before installation, it should be confirmed whether the motor and planetary reducer are in good condition, and strictly check whether the dimensions of each part connected to the drive motor and the reducer match. This refers to the positioning boss and shaft diameter of the drive motor flange and the reducer flange. The dimensions and tolerances between the positioning grooves and apertures; wipe the dirt and burrs on the surface of the cooperation.

The problem of broken shaft caused by the output of the planetary precision reducer is too small

If it is not the drive motor shaft that is broken, but the output shaft of the reducer is broken, in addition to the reasons for the poor concentricity of the output end of the reducer, there are the following possible reasons.

First of all, the wrong type selection makes the output of the reducer not enough. Some users mistakenly think that only the extra output torque of the selected reducer can meet the working requirements when selecting the type, but it is not.

First, the additional output torque of the drive motor is multiplied by the speed ratio, and the value obtained is in principle smaller than the corresponding additional output torque supplied by the reducer product sample;

2. At the same time, the overload capacity of the drive motor and the larger working torque required in practical use should also be considered.

In theory, the maximum working torque required by the user must be less than 2 times the additional output torque of the reducer. Especially in some applications, it is necessary to strictly abide by this guideline, which is not only to protect the internal gears and shafting of the reducer, but also The main thing is to prevent the output shaft of the reducer from being twisted off.

If these factors are not taken into account, once there is a problem with the installation of the equipment, the output shaft of the reducer will be stuck by the load, and the overload capacity of the drive motor will still make it continue to increase the output until the output shaft of the reducer receives more than the force. The greater the output torque, the shaft will be twisted. If the additional output torque of the reducer has a certain margin, the bad situation of twisting the output shaft will be prevented.

Secondly, in the process of acceleration and deceleration, if the instantaneous impact torque received by the output shaft of the reducer exceeds twice its additional output torque, and this acceleration and deceleration are too frequent, the reducer will eventually break down. Shaft. If such a situation occurs, careful calculation should be considered to increase the torque margin.
