How to effectively improve the noise problem of harmonic reducer

There are many reasons for the formation of gear noise, especially in high-speed operation, noise and vibration are problems that require customer service, how can the harmonic reducer effectively improve the noise problem? 　　 1. To choose gears with high vibration damping rate, 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. The proper lubrication of the harmonic reducer should be adequately lubricated, and the lubricating oil with high viscosity has low noise. 3. The 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. The harmonic reducer uses high-precision 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, in addition to improving the gear and various accuracy, can also improve the roughness of the tooth surface. So this has a very good effect on reducing noise. 5. Harmonic gear reducer adopts smooth tooth surface grinding, rubbing and grinding can reach ideal tooth surface roughness. In addition, it can also improve the tooth surface roughness by warming up in oil for a period of time, which reduces the noise. effect. 　　6. ​​The correct tooth surface contact implements tooth surface drum processing or cutting end processing to prevent single-piece contact, 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.
