Dynamic Characteristics Analysis of Bearings Based on Modification Cycloidal Pinwheel Reducer

Abstract

Taking the cycloid pin gear reducer as the research object, the bearing force of the cycloid pin gear reducer shaft is calculated under different modification amount. Based on the Hertz theory, the contact stress and deformation of the bearing under different modification amounts are calculated. Based on the transmission principle of cycloid pin wheel reducer, the model of cycloid wheel and bearing is established and the finite element analysis is carried out. The analysis showed that the Hertz theoretical solution is consistent with the finite element analysis solution, which showed the correctness of the finite element results. The stress and deformation of the bearing obtained under different modification amounts of the cycloid wheel are not changed much. It can indicate that the cycloid wheel modification has no significant influence on the bearing force. Therefore, the research content of this paper has certain reference value for the design and optimization of cycloid pinwheel reducer.
