There are many reasons for the formation of gear noise, especially in high-speed operation, noise and vibration are problems that need customer service, how can harmonic reducer effectively improve noise problems?

1. It is necessary to choose gears with high vibration attenuation rate and light load and low rotation. It is a good choice to use plastic gears, but pay attention to the problem of temperature rise. Cast iron gears are more effective in reducing noise than steel gears.

 

2. Proper lubrication of harmonic reducer should be fully lubricated, and lubricating oil with high viscosity has low noise.

3. The rotation speed of low-speed operation and low-load gear 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 become smaller. Grinding the tooth surface can not only improve the gear and various precisions, but also improve the tooth surface roughness. So this has a great effect on reducing noise.

5. The harmonic reducer adopts smooth tooth surface grinding, rubbing, and grinding to achieve the ideal tooth surface roughness. In addition, the tooth surface roughness can also be improved by warming up in oil for a period of time, which reduces noise. effect.

6. Correct tooth surface contact Implement tooth surface drum processing or cutting end processing to prevent single-piece contact, and noise will naturally be reduced. Proper tooth profile trimming is also effective in reducing noise. Eliminate bumps or scratches on the tooth surface.

7. Appropriate backlash is generally a more balanced load, and a slightly larger backlash is also effective in reducing noise.
