As professionals in the mechanical and electrical industry know, the noise generated by gearmotors during operation is a headache for many people, especially for worm gear gearmotors. Reducing noise and ensuring stability during operation is the primary condition for the quality of the reduction motor.

As professionals in the mechanical and electrical industry know, the noise generated by gearmotors during operation is a headache for many people, especially for worm gear gearmotors. Reducing noise and ensuring stability during operation is the primary condition for the quality of the reduction motor.
For how to achieve this goal, many domestic and foreign manufacturers regard the changes in gear tooth meshing stiffness in gear transmission as the main factors of gear dynamic load, vibration, and noise. By using the method of shape modification, the dynamic load and velocity fluctuations are reduced to a relatively small extent, in order to achieve the goal of reducing noise. This method has been proven to be a more effective method in practice.
The foot plate type of the reduction motor should be installed on a vibration free and very sturdy horizontal foundation. In situations where inclined installation is necessary, the inclination of the axis of the reduction motor should not exceed 15 degrees. If other special installation forms other than foot plate horizontal installation and flange vertical installation are required, corresponding lubrication and sealing measures must be taken to ensure sufficient lubrication of the reduction motor to prevent oil leakage.
In situations of high impact, vibration, or frequent starting, in addition to connecting the base and foundation with anchor bolts, positioning pins (provided by oneself) need to be used for fixation. However, using this method requires shaping equipment in the process, which is often impossible for large, medium, and small factories to implement. After years of research, a gear design method is proposed to reduce or avoid the impact of meshing pitch circle by optimizing gear parameters, such as modification coefficient, tooth height coefficient, pressure angle and Centre-to-centre distance, so that the meshing impact speed can be reduced to a relatively small value, and the ratio of meshing impact speed to meshing impact speed is in a certain value range, which can also significantly reduce the noise of gears during the operation of reduction motors.
