摘　　要：齿轮传动的功率损失主要在于:啮合面的摩擦损失、轮齿搅动润滑油时的油阻损失和轮轴支承在轴承中和轴承内的摩擦损失。齿轮传动的效率即指一对齿轮的从动轮(轴)输出功率与主动轮(轴)输入功率之比。从实验角度入手,指出影响封闭齿轮传动效率的因素是封闭力矩。The loss of power by using the wheel gears mainly lies in the loss of the surface of action, the loss of oil resistant when the gears stir the lubricating oil, and the loss of bearings. The efficiency by using the wheel gears refers to the ratio of the exportation power of the driven round with the importation power of the main rotmd. Illustrates, from the angle of experiment, the factors which influence the power of closed wheel gears is dosed moment.
