摘　　要：通过对非对称渐开线圆柱齿轮传动的啮合特性分析,建立了齿轮动力学模型,并利用数值积分和数值仿真方法对其进行了非线性振动研究.针对齿轮传动的时变刚度特点,比较了标准齿轮与非对称齿轮的振动特性.结果表明:在同等工况下,非对称齿轮比标准齿轮具有更良好的动力学特性.A dynamic model of involute gears with asymmetric teeth was proposed based on the analysis of mesh characteristics when the gears transmitting. The numerical integral and numerical simulation method were used to study nonlinear vibration. Considering the time-variant mesh stiffness when the gears transmitting, the vibration characteristics were compared between gears with symmetric teeth and with asymmetric teeth. The results showed that under the same condition the gears with asymmetric teeth had better dynamic characteristics than those with symmetric teeth.
