摘　　要：采用集总质量法建立二分支斜齿轮传动系统的动力学模型及动力学方程,考虑轮齿啮合偏差和时变啮合刚度等激励因素,研究分别在不同支承刚度和不同分扭角度情况下,传动系统的动载系数和均载系数的变化规律,得出如下结论:1较大的支承刚度有利于改善传动系统的均载特性和运转平稳性,在16倍初始支承刚度下系统的均载特性已趋近于理想情况;2二分支斜齿轮传动系统的分扭角度对其动载系数和均载系数有较大影响,在分扭角度为110°时系统的均载特性最优;3即使1μm的轮齿啮合偏差也会对系统的均载特性产生较大不良影响,应严格控制.The lumped mass method was adopted to establish the dual-path helical gear transmission system dynamic model and dynamic equation; and considering the gear meshing deviation and time-varying meshing stiffness, change rule of the dynamic load coefficient and the load sharing coefficient of transmission system were studied in the case of different sup- port stiffness and separated torque angles. The results show that： （1） the larger support stiffness is conducive to the transmission system load sharing characteristic and stability, and the load sharing characteristic is close to the ideal at the case of 16 times the initial support stiffness; （2） the dual-path helical gear transmission system＇s separated torque angle has a great influence on the dynamic load coefficient and the load sharing coefficient, and the sys- tem loading sharing characteristic gets the most optimal at the separated torque angle of 110 degree; （3） even 1μm meshing deviation has sharing characteristic, so it should be strictly a great negative effect on the system loading controlled.
