Abstract Star type gear reducer is a kind of speed reducer drive important, are widely used in machinery, construction and other fields. It has such as small volume, light weight, compact structure, transmission ratio characteristics of high transmission efficiency, stable operation. This graduation design is based on the characteristics of the star gear is designed, and its analysis using PRO/E 3D modeling and motion mechanism.    

First, fully understand the basic principle of star type gear reducer, transmission mode and the basic structure, familiar with and learn the 3D drawing software PRO/E, on this basis, each part model by using the 3D modeling function of PRO/E drawing star reducer, including the sun wheel, a wheel, double internal gear, input and output shaft. 

Secondly, function of motion simulation analysis of learning and using PRO/E software organization, assembly of the painting of parts, and then carries on the analysis of mechanism is provided, the simulation in the working condition, and make a simulation video. 

Finally, select a gear part of the displacement in the state of motion and the stress and strain distribution were analyzed using the ANASYS software, the software to calculate, the gear part displacement in X direction motion state, the stress, strain distribution.
