Analysis of the Key Structures of RV Reducer Based on Finite Element Method

[摘要] In this paper, key structures of the RV reducer were calculated by finite element method respectively, including the stress and deformation of cycloidal-pin wheel and eccentric shaft. The results show that the contact stress and equivalent stress of cycloidal-pin wheel and eccentric shaft are far less than the strength of materials. It means the strength is not the main consideration of design and manufacture. The stiffness of eccentric shaft is less than the cycloidal-pin wheel, which had a great influence on the transmission accuracy of the machine. In order to improve the rigidity so as to improve the transmission accuracy of gear reducer machine, the modification methods and modification should be chosen to design by the deformation.
