Sažetak

The non-circular gear hydraulic motor is a new type of low-speed and high-torque motor, which is characterised by large unit displacement, smooth operation, high resistance to oil contamination, and high volumetric efficiency. The non-circular planetary gear system, as the core transmission mechanism of the non-circular gear hydraulic motor, and its design accuracy are the key to improving the processing accuracy and transmission performance. Having addressed the issue of designing a non-circular planetary gear system, based on the principle of gear meshing, coordinate transformations and meshing equations of internal and external meshing of the non-circular planetary gear system are solved, a mathematical model of the non-circular planetary gear system is established, and parametric tooth surface equations with a unified expression are obtained. The accuracy of the model is verified through the motion characteristics analysis of the model and the effects of input speed and load on the dynamic meshing characteristics are obtained. The design method proposed in this paper can directly obtain coordinates of the tooth surface data of the sun gear and the ring gear, which is of great significance for improving the efficiency of the dynamic design of the non-circular planetary gear system.
