How to remove noise problems in geared motors?

Electromechanical industry people know that the noise when the motor is a lot of work so that a headache is a problem, especially the high efficiency gearbox noise is particularly large. Reducing noise and ensuring stability at runtime is the primary condition for the quality of the motor.
For how to achieve this goal, many domestic and foreign manufacturers have cycloidal reducers meshing stiffness changes as the gear dynamic load, vibration and noise of the main factors. With the modified method, so that the dynamic load and speed fluctuations to a minimum, in order to achieve the purpose of reducing noise. This method proved to be a more effective method in practice.
 The caliper of the geared motor shall be mounted on a non-vibrating, very strong level, and the inclination of the axis of the geared motor shall not be greater than 15 degrees when it is necessary to be tilted. If you need to use in addition to foot horizontal installation and flange mounted outside the installation of other special forms, must take the appropriate lubrication and sealing measures to ensure that the Hypoid Gear Reducer can be fully lubricated to prevent oil spills.
In the use of shock, vibration or frequent use of the occasion, the base and the base in addition to the foot bolt with the connection, but also need to use the positioning pin (self) to fix. But with this method, the process needs to have modified equipment, the majority of small factories are often unable to implement. After years of research, it is proposed that by optimizing the gear parameters such as the displacement coefficient, the tooth height coefficient, the pressure angle and the center distance, the penetration impact velocity is minimized and the ratio of the outburst impact velocity to the penetration impact velocity is at a certain value Range, to reduce or avoid the impact of meshing rounds of the gear design method, but also significantly reduce the gear motor gear noise.
