What Are The Noise Reduction Methods for Micro Planetary Reduction Motors?

Methods for reducing noise in micro planetary geared motors:

1. Choose materials with high vibration damping rates: For lightly loaded, low-speed gears, plastic gears are a good choice, but they should be aware of temperature rise. Cast iron gears are more effective at reducing noise than steel gears.

2. Proper lubrication: Provide adequate lubrication. Lubricants with high viscosity produce lower noise.

3. Low-speed operation and low loads: Gear speeds should be kept to a minimum. Reducing the relative speed can also reduce noise.

4. Choose high-precision gears: Reducing pitch error, tooth profile error, tooth groove deviation, and tooth rib error will reduce noise. Grinding the tooth surface not only improves gear and overall precision but also improves tooth surface roughness, which is very effective in reducing noise.

5. Use smooth tooth surfaces: Grinding, rubbing, and honing can all achieve ideal tooth surface roughness. Warming up the gear in oil for a period of time can also improve tooth surface roughness, which also helps reduce noise.

6. Proper Tooth Contact: Applying drumming or chamfering to the tooth surfaces prevents single-piece contact, which will naturally reduce noise. Proper tooth profile trimming is also effective in reducing noise. Remove any dents or scratches on the tooth surfaces.

7. Proper Tooth Backlash: Generally, with a relatively balanced load, a slightly larger backlash can also help reduce noise.
