Three Rings Reducers

Three Rings Reducer is an advanced transmission mechanism whose basic version is composed of one output shaft, two input shafts and three annular drive plates.


  • 1. High load capacity, superior performance, long service life
  • 2. Large and dense gear ratio, 1 stage reduction ratio 11~99, 2 stage reduction ratio maximum 9801
  • 3. Smooth operation, low noise, little vibration, the noise is less than 78 dB, and the vibration amplitude is less than 0.025mm
  • 4. High efficiency, single stage 92%~96%
  • 5. Compact structure, light weight
  • 6. Multiple shaft configurations. The two input sections of three rings transmission mechanism can be integrated with helical gear pair or spiral bevel gear pair
