摘　　要：基于渐开线直齿圆柱齿轮传动中功率输入和输出的关系,推导出包含滚动摩擦和滑动摩擦在内的瞬时摩擦效率、平均摩擦效率和总的摩擦损失等公式;基于包含最小平均摩擦效率、最小摩擦损失、最大弹性流体动力润滑的最小油膜厚度等齿轮传动的最佳摩擦学性能,通过优选齿轮的传动参数,从而提高了传动效率;以上全过程是基于UG 3D软件系统的,因此,是全参数化的和集成化的;通过实例运算,分别给出了最佳的优化结果及相关过程的仿真曲线。From the relation of input power and output power included in involute straight gear transmissions, the formulae of instantaneous friction efficiency, average friction-efficiency and total friction-loss were derived. Based on the best tribology performances that are minimization of average friction-efficiency and friction-loss and maximization of minimal oil- film thickness under elastohydrodynamic lubrication and so on, gear transmissions efficiency was increased after selecting the optimal transmission parameters. All above course is based on UG 3D software, and it is all parameterized and all integratived. A sample was operated and the optimum results and the simulation curves were obtained.
