文章在计算斜齿轮时变接触线基础上,采用数值编程快速计算主动轮齿面摩擦力和齿面摩擦扭矩.通过分析齿面摩擦力和齿面摩擦扭矩的均方根以及波动率后可知,时变接触线的波动是影响齿面摩擦力以及齿面摩擦扭矩的主要因素.在文中选定的参数范围内,齿面摩擦力的波动和齿面摩擦扭矩的波动与时变接触线的波动变化规律基本一致,呈现出一种10°-20°和20°-30°的变化规律,为工程减振降噪提供了理论参考.

Based on the calculation of time-varying contact line, the numerical algorithm is adopted to cal-culate the friction force of tooth surface and the friction torque with different helix angles. After analyzed Root Mean Square and fluctuation ratio of friction force of tooth surface and friction torque, the conclusions were obtained: the fluctuation ratio of time-varying contact line is the principal factor for the change of friction force of tooth surface and the friction torque. In the range of parameters selected, the fluctuations of tooth surface friction force and friction torque are the same as the volatility of time-varying contact line and show a change law between 10°-20° and 20°-30°, which provide a theoretical reference to reduce noise and vibration in engineering.
