The low noise of the reducer will be the trend of future industry development

The gear reducer is a power transmission mechanism that uses a gear speed converter to reduce the number of revolutions of the motor (motor) to the desired number of revolutions and obtain a larger torque.In today's organizations used to transmit power and motion, the use of reducers is quite extensive.
  
  The noise pollution of the reducer is also a major factor that damages the environmental protection, which will hinder people's normal rest, study and work.      
  It is an important research topic in the industry to reduce the gear transmission noise when the reducer is running. Many scholars at home and abroad regard the change of gear tooth meshing stiffness in gear transmission as the main factor of gear dynamic load, oscillation and noise.
  
  Use the method of modification to minimize the dynamic load and speed fluctuation to achieve the purpose of reducing noise.This approach has proved to be a more useful approach in practice.However, in this way, there is a need for repairing equipment in the process, which is often impossible for the majority of medium and small factories.      
  
   The noise of the worm reducer has a great influence on the accuracy of operation stability, the touch accuracy of the gear, the movement accuracy of the gear, and the installation accuracy. If you want to reduce the noise of the reducer, you must know the cause of the noise. The noise is caused by the effect of periodic alternating force on the bearing and the box caused by the meshing of the internal gears during its operation.      
  
  After years of research, it is proposed to optimize gear parameters, such as displacement coefficient, tooth height coefficient, pressure angle, and center distance, so as to minimize the impact speed of meshing, and the ratio of the impact speed of meshing out to the impact speed of meshing is at a certain value. Scale, gear design methods that reduce or prevent the impact of meshing pitch circles can also significantly reduce gear noise.
