Computer Simulation on Quasi-ellipsoidal Gear Transmission

摘要

Quasi-ellipsoidal gear transmission mechanism, which is the newest transmission mechanism used for robot flexible wrist at present, has simple structure, light weight,small dimension, high sensitivity and can accurately carry out the motion transmission in all-direction. It is a new type of transmission used for robot flexible wrist at present. Different from ordinary transmission mechanisms it is a spatial mesh with double DOF. Its design is complicated, and there are many approximate treatments in checking interference of flank and distribution of teeth. The purpose of this paper is to verify the reliability of the design by means of computer simulation.
