When the machine is running, there will definitely be some noise. If the noise is too big, it will make people uncomfortable. The speed reducer is the same, so when we use the motor deceleration when how to adjust in order to reduce the noise it is running, let Matsuoka motor to tell you. Now we generally regard the change of meshing stiffness in gear transmission as the main factor of dynamic load, vibration and noise. In order to reduce the noise, the dynamic load and velocity fluctuation are minimized by modifying the shape. This method is proved to be an effective one in practice. However, there are some regrets, that is, the company's training equipment is generally not, so it can not be implemented. Reducer noise is small, workers in the environment will not be anxious, can work better, so reduce the noise is necessary. So businesses should deal with this.
