How to solve the noise problem of worm gear reducer

　　Worm gear reducer is a kind of deceleration equipment. The friction of its parts will produce sound during operation. However, if the sound of the equipment is too loud, it is not a normal situation. If we encounter equipment noise, how should we solve it?
　　1. It is necessary to choose gears with high vibration damping rate and light load and low rotation. Plastic gears are a good choice, but attention should be paid to the problem of temperature rise.Cast iron gears are more effective in reducing noise than steel gears.
　　2. Proper lubrication should be adequately lubricated, and lubricating oil with high viscosity has low noise.
　　3. The rotation speed of low-speed operation and low-load gears should be kept as low as possible, and the load should be reduced as much as possible to reduce noise.
　　4. Choose high-precision worm gear reducer gears to reduce the pitch error, tooth profile error, tooth groove deviation, and tooth rib error, and the noise will be reduced.Grinding the tooth surface can not only improve the gears and various precisions, but also improve the roughness of the tooth surface.So this has a very good effect on reducing noise.
　　5. Using smooth tooth surface grinding, rubbing, and stone grinding can achieve ideal tooth surface roughness. In addition, warming up in oil for a period of time can also improve the tooth surface roughness, which reduces noise.
　　6. The correct tooth surface contact is carried out to prevent single-piece contact by drumming or cutting the end of the tooth surface, and the noise will naturally be reduced.Proper tooth shape trimming is also effective in reducing noise.Eliminate bumps or marks on the tooth surface.
　　7. Proper backlash is generally more balanced than the load. A slightly larger backlash also has an effect on noise reduction.
　　The above introduces the solution to the noise of the worm gear reducer. You can refer to the content of this article when you encounter this kind of problem. I hope it can be helpful to you.
