摘　　要：由于设计、制造、加工、热变形及装配误差的存在,齿轮传动在啮合过程中不可避免地存在啮合间隙;基于变形协调设计原理,设计了金属橡胶复合齿轮副,运用有限元分析的方法对复合齿轮副在不同温度下的变形量、是否变形协调设计齿轮副动态啮合力进行仿真分析。仿真结果表明:在不同温度下,复合齿轮副变形不同,温度对复合副变形影响较大;变形协调设计可以减小齿轮副动态啮合力和改变振动峰值及对应的振动频率。该研究为复合齿轮副啮合特性改善、传动精度提高及振动噪声减小等方面提供理论依据及技术支撑。As the design, manufacturing, processing, thermal deformation and assembly errors, there is an inevitable meshing gap in the meshing process of gear transmission, based on the deformation coordination design principle, a metal rubber composite gear pair has been designed, and the finite element analysis method has been used to simulate the deformation of the composite gear pair at different temperatures and the dynamic meshing force of the gear pair whether deformation coordination design. The simulation results show that the deformation of the compound gear pair are different under different temperatures, and the temperature has a great influence on the deformation of the compound gear pair;the deformation coordination design can reduce the dynamic meshing force of the gear pair and change the vibration peak value and the corresponding vibration frequency. The research provides theoretical basis and technical support for the meshing characteristics improving, the transmission accuracy improving and the vibration noise reducing of the compound gear pair.
