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.
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.
减速机内部齿轮的齿距和压力角 小齿距能保证有较多的轮齿同时接触，齿轮重叠增多，减少单个齿轮挠曲，降低传动噪声，提高传动精度。较小的压力角由于齿轮接触角和横六角空心砖模具向重叠比都比较大，因此运转噪声小、精度高。
The tooth distance of the gear in the reducer and the ***all pitch of the pressure angle can ensure that there are more teeth at the same time, the overlap of the gear is increased, the deflection of the single gear is reduced, the tran***ission noise is reduced, and the tran***ission precision is improved. The ***aller pressure angle is due to the larger contact ratio between the gear contact angle and the six corners of the hollow brick mold, so the running noise is ***all and the accuracy is high.
