Cycloid Pinwheel Planet Drive Nonlinear Meshing Stiffness Calculation and Analysis
Mathematical model of pin-cycloid meshing stiffness is set up by profile modification with clearance meshing analytical method. An universal program of pin-cycloid meshing stiffness is compiled, by which meshing stiffness is computed. Computing results show that meshing stiffness is changing with time greatly, which indicate that changing meshing stiffness is a main factor on vibration of whole machine. Better value of modification and curtate ratio coefficient are gotten by analyzing factors on meshing stiffness,such as value of modification ,curtate ratio coefficient and pin-cycloid radius etc. Computing and analytical results lay a foundation for ring-plate-type pin-cycloid planetary drive dynamics characteristics investigation deeply.
