Transmission Efficiency Analysis of Pin-Cycloid Planetary Gearing Reducer Applying Two-Stage Speed Reduction used in Propeller Pitch Variator

摘要

This paper introduces a pin-cycloid planetary gearing reducer in two teeth difference applied in propeller pitch variator. To be considered, the main factors are pin-cycloid gear meshing efficiency, bearing efficiency and output mechanism efficiency. Finally, the transmission efficiency of this new-type reducer is calculated by the inverted mechanism method, which is the foundation of prototype test in future.
