摘要

提出了一种精度更高的新模型，用于模拟无制造误差和安装误差的直齿直齿轮的动态特性。为了更好地解释单齿接触最低点和最高点(LPSTC, HPSTC)附近的齿载分担过程，考虑了齿边接触发生时实际接触路径的载荷引起的扩展。此外，采用了精确的摩擦模型，考虑了弹流润滑膜的形成对齿轮振动的影响。提取了不同运行速度下的仿真结果，并对所提模型进行了评价。该模型以模块化方式构建，因此可以用作大型机构的构建块，例如齿轮系和多级齿轮箱。

A New Model of Improved Accuracy for the Dynamic Behavior of Spur Gears

A new model of improved accuracy is proposed for the simulation of the dynamic behavior of a pair of spur gears that are free from manufacturing and mounting errors. The load-induced expansion of the actual path of contact with the occurrence of tooth edge contact is taken into account in order to better explain the tooth load sharing process near the lowest and highest point of single tooth contact (LPSTC, HPSTC). In addition, an accurate friction model is utilised and the effect of elastohydrodynamic lubricant film formation on gear vibration is taken into account. Simulation results are extracted for various operating speeds and an evaluation of the proposed model is conducted. The model is constructed in a modular fashion and can consequently be used as a building block for larger mechanisms, such as gear trains and multi-stage gearboxes.
