Finite element analysis of planet-cycloid reducer based on COSMOSworks

Aiming at solving the problems in manufacturing of cycloidal gear,the planet-cycloid reducer model in consideration of manufacturing error was developed applying SolidWorks after the preliminary design and theoretical calculation.Based on the model,the stress and strain distribution of main load bearing parts like cycloidal gear and pin gear were obtained by finite element method.And the finite element model analysis of input and output shaft were also discussed.The results indicate that the design of planet-cycloid reducer is improved by using virtual prototype technique.
