Abstract: Computer was used to simulate the machining process of tooth profiles of ring gear of epicyclic drive with eccentric wheel and push rod. The calculating formulae of the minimum curvature radius and pressure angle of practical tooth profiles were established. The influence factors of minimum curvature radius and pressure angle were analyzed, and the calculation & analysis showed the eccentricity obtained is the most important parameter of this epicyclic drive.
