Analysis of the cause of noise from the geared motor

The noise problem of the geared motor has always been a key research topic at home and abroad. The noise of the geared motor is mainly caused by the friction, vibration and collision of the transmission gear, so how to effectively reduce and reduce the noise to meet the requirements of environmental protection. It has become an important research topic in the development of current geared motors! After years of research, scholars have proposed to reduce the noise of gears of geared motors by optimizing gear parameters, etc., and the facts show that these methods can effectively reduce the noise problem of geared motors.

In the family of geared motors, planetary geared motors are widely used in servo, stepping, DC and other transmission systems due to their small size, high transmission efficiency, wide deceleration range and high precision. Its role is to reduce the speed increase torque and reduce the load/motor moment of inertia ratio under the premise of ensuring precision transmission.

Proper installation and use of planetary geared motors is a very important problem. Only the correct installation and use of planetary geared motors can keep the geared motors in good working condition and longevity. It can be said that the installation and maintenance of geared geared motors Life expectancy has a major impact. The following is a brief analysis of the reasons for the geared motor and the drive motor to break the shaft, and describes how to properly install the planetary geared motor.

First, the broken shaft problem of the geared motor with different heart is caused by the difference between the motor and the reducer. When the concentricity of the motor and the reducer is very good, the motor output bearing is only subjected to the rotational force, and the operation will be smooth. However, when the center of the heart is different, the radial force to be received by the output shaft becomes larger. The radial force of the output shaft itself can cause deformation or even breakage at the input end of the reducer.

Second, the output of the geared motor is too small, the output of the shaft is broken due to the poor concentricity of the geared motor itself. The output shaft of the geared motor is broken, but the following reasons are: Firstly, the wrong selection leads to insufficient output of the geared motor. Secondly, during the acceleration and deceleration of the geared motor, the instantaneous torque of the output shaft of the geared motor exceeds twice its rated torque, and this acceleration or deceleration is Too often, it will eventually cause the geared motor to break. Third, the correct installation of the geared motor, the correct installation, use and maintenance of the geared motor is an important part of ensuring the normal operation of mechanical equipment.
