摘要
为研究面齿轮传动力学特性及噪声辐射,通过建立面齿轮传动的弯扭耦合动力学模型,在分析轴承支承处动载荷的基础上,结合有限元法和边界元法,形成了面齿轮传动的噪声辐射计算流程.此外,利用该计算流程,开展了算例分析,讨论了单一几何参数和工况对面齿轮传动噪声辐射的影响规律.仿真结果表明:模数和传动比对改善面齿轮传动噪声辐射有益,压力角对其噪声辐射影响不明显.研究结果为低噪声面齿轮传动的设计奠定了必要的理论基础.
To investigate the dynamic behaviors and noise radiations of face gear drives, a calculation procession of noise radiations of face gear drives, which is based on lumped mass method, finite element method （FEM） and boundary element method （BEM）, was proposed. Furthermore, a noise radiation of an examp ences of base geometric parameters and operating cond e case was simulated, and the influ- tions on noise radiations of face gear drives were discussed. The analytic results indicate increasing module and drive ratios would benefit to reduce noise radiations, and pressure angles would be insensitive for noise radia- tions, et al. These contributions would be helpful to improve the design of face gear drives associated with low noise radiations.
