Three-Ring Reducer
features:
1. High carrying capacity, superior performance and long service life
2. The gear ratio is large and dense, the first-stage reduction ratio is 11~99, and the second-stage reduction ratio is the largest 9801
3. Smooth operation, low noise, low vibration, noise less than 78 dB, vibration amplitude less than 0.025mm
4. High efficiency, single stage 92%~96%
5. Compact structure and light weight
6. Multi-axis configuration. The two input parts of the three-ring transmission mechanism can be integrated with a pair of helical gears or a pair of spiral bevel gears
