摘要
刚度和阻尼等啮合参数是螺旋锥齿轮非线性振动的主要影响因素。考虑啮合刚度和啮合阻尼的时变性，采用二次谐波形式展开，建立了螺旋锥齿轮副振动平衡方程。基于不同啮合状态下间隙函数的变化，研究了啮合刚度及啮合阻尼在三种啮合状态下对螺旋锥齿轮副啮合特性的影响规律。采用Matlab进行分析，给出了平均啮合阻尼、谐波啮合阻尼、主谐波啮合刚度和次谐波啮合刚度对啮合点振动位移的影响曲线。结果表明增大平均啮合阻尼和降低主谐波啮合刚度会降低振动位移峰值，提高齿轮传动平稳性。
Abstract
Meshing parameters which include stiffness and damping are key factors of nonlinear vibration for spiral bevel gear. Considering the time-varying characteristics of meshing stiffness and meshing damping, developing as second-order Fourier series, vibration equation of spiral bevel gear was established. Based on the variation of clearance function under different meshing state, the effect of meshing stiffness and meshing damping on spiral bevel gear under three meshing state was studied. Using Matlab to analysis, the vibration displacement curves of meshing point was given when mean meshing damping, harmonic meshing damping, fundamental harmonic meshing stiffness and sub-harmonic meshing stiffness are considered. The results show that increasing mean meshing damping and decreasing fundamental harmonic meshing stiffness could decrease vibration displacement peak and improve transmission stability.
