Dynamic Simulation of Cycloid Wheel at Two Support Points of Needle Gear pin for New Three-Gear Pin-Cycloid Driven Speed Reducer

Pin-cycloid driven speed reducer with three cycloid gears adopts the new driving structure of three cycloid gears at eccentric angle of 120 between each other. Three main stresses act on the cycloid gears: the stress between pin gear and cycloid wheel gear, the stress on cycloid wheel by cylinder pin of output mechanism and the stress on cycloid wheel by bearing of rotating arm. In this paper, the stress between needle gear and cycloid wheel gear is analyzed mainly by analysis.
