一般性斜齿面齿轮两分支传动系统动力学建模与均载特性

To analyze the dynamic load equalization properties of the dual-branch transmission system composed of offset and non-orthogonal general helical face gear, the force of the offset and non-orthogonal general helical face gear and the arrangement of its dual-branch transmission system were explored. The lumped mass method was used to model the dynamics of the dual-branch transmission system of the general helical face gear, and the Runge-Kutta method was used to solve the dynamic equations. The variation law of the two-stage load equalization coefficients of the system with various influencing factors was studied. The results show that the load equalization coefficients of the shunt stage and the confluence stage are usually not equal. The input speed has an important influence on the two-stage load equalization coefficient, and the load equalization coefficient has multiple peaks at different speeds. The bias error and shaft misalignment error in the error have a great influence on the two-stage load equalization coefficient; when there is installation error, reducing the torsional stiffness and increasing the input load can reduce the two-stage load equalization coefficient. The excessive support stiffness of helical gear 1 is not conducive to the load sharing of the system; reducing the fluctuation amplitude of the comprehensive meshing stiffness of the two-stage gear pair can effectively reduce the two-stage load equalization coefficient.
