Abstract:
In view of the quantity of cycloidal gear modification,tooth contact deformation and the effects ofthe pin gear bending deformation,the contact stress between the pin gear and the various cycloidal gears iscalculated by Hertz theory. Based on the meshing principles of cycloid pin gear planet transmission,the RVsecond-level finite element model of pin-cycloid meshing transmission is accurately established by using the fi-nite method. According to the actual working condition of fixed pin gear and cycloidal gears outputing,thenodes in the outer ring of the pin gear are constrained,and the rigid beam is employed to simulate the planeteasel output gears. Meanwhile,the rigid cell is employed to simulate the eccentric shaft crank. The hinge linktechnology is employed to simulate the rotation of crank relative to cycloid pin gear hole. Based on the actualworking condition of the constrained and simulated bearing of the bearing bore,a torque load is applied in theoutput unit centroid and the cycloid-pin gear contact nonlinear analysis is further employed to get stress, straimcontours of the eycloidal gear. Comparative analysis of the results of theoretical calculation and finite element a-nalysis offers a theoretical basis for optimal design of cycloid gear and the effective method of numerical simu-lation.
