Quasi-static tooth contact analysis of hypoid gear drive with coaxiality deviations

摘要

In this paper, quasi-static tooth contact analysis of hypoid gear drive with coaxiality deviations was presented. Firstly, coaxiality deviations of hypoid gear drive were defined, and the multi-tooth meshing equation with coaxiality deviations was established, as well as the process of multi-tooth contact analysis (MTCA). Secondly, a hypoid gear drive was chosen for the case studies and the effects of coaxiality deviations on the meshing characteristics were obtained. The combined effect of coaxiality deviations was obtained, and the optimal setting method of the initial phase angles of the gear and the pinion axis eccentricities on the transmission error was discussed. Furthermore, the FEM of a simplified hypoid gear drive system has been set up, which results confirm the correctness of the formula calculation method. The research provided a theoretical reference for optimal design, dynamic analysis, mounting adjustment, performance testing, etc., of spiral bevel and hypoid gear drives.
