安装前，将电机输入轴、***凸台及减速机连接部位的防锈油用或锌钠水擦拭净。其目的是保证连接的紧密性及运转的灵活性，并且防止不必要的磨损。

Before installation, the anti rust oil of the motor input shaft, the itioning protruding platform and the connecting part of the reducer is cleaned with gasoline or zinc sodium water. The pure is to ensure the tightness of the connection and the flexibility of the operation, and to prevent unnecessary wear.

减速器是一种由封闭在刚性壳体内的齿轮传动、蜗杆传动、齿轮-蜗杆传动所组成的***部件，常用作原动件与工作机之间的减速传动装置 。在原动机和工作机或执行机构之间起匹配转速和传递转矩的作用，在现代机械中应用极为广泛。

The reducer is an independent component of gear tran***ission, worm drive and gear worm drive enclosed in a rigid shell. It is often used as a deceleration between the original and the working machines. The matching speed and transfer torque between prime movers and working machines or actuators are widely applied in modern machines.

降低减速机运转时的齿轮传动噪声已成为行业内的重要研究课题，国内外不少学者都把齿轮传动中轮齿啮合刚度的变化看成是齿轮动载、振动和噪声的主要因素。用修形的方法，使其动载荷及速度波动减至小，以达到降低噪声的目的。这种方法在实践中证明是一种较有效的方法。减速机行业属于国民经济发展的基础行业，从生活家电到汽车飞机、从生产工具到建筑机械，几乎所有的机械传动系统中都需要使用到减速机。

Reducing the gear tran***ission noise of the reducer has become research topic in the industry. Many scholars both at home and abroad regard the change of gear tooth meshing stiffness as the main factor of gear dynamic load, vibration and noise. The method of modification is used to minimize the dynamic load and speed fluctuation in order to reduce noise. This method is proved to be a more effective method in practice.

减速机内部齿轮宽度 在减速机传动空间允许时，增加齿轮宽度，可以减少恒定扭矩下的单位负荷。降低轮齿挠曲，减少噪声激励，从而降低传动噪声。

The width of the internal gear of the reducer can be increased when the tran***ission space of the reducer is allowed, so that the unit load under ctant torque can be reduced. Reduce gear deflection, reduce noise excitation, thereby reducing tran***ission noise.
