安装前确认电机和减速机是否完好无损，并且严格检查电机与减速机相连接的各部位尺寸是否匹配，这里是电机的*凸台、输入轴与减速机凹槽等尺寸及配合公差。

Before installation， confirm whether the motor and reducer are in good condition， and strictly check whether the size of each part of the motor connected to the reducer i*atch. Here is the size and fit tolerance of the motor"s locating lug， input shaft and reducer groove.

对减速机箱体进行共振测试，找出共振位 置，reducer型号，增加适当的筋条（板），reducer哪家好，可以****箱体的刚度，减少箱体的振动，实现降噪。多级传动时要求瞬时传动比的变化尽量小，以保证传动平稳，冲击及振动小，噪声低。

By testing the resonance of the reducer box， finding out the resonance and adding appropriate ribs (plates)， the stiffness of the box can be increased， the vibration of the box can be reduced and the noise can be reduced. In multistage tran*ission， the change of instantaneous tran*ission ratio should be as *all as to ensure stable tran*ission， low impact and vibration， and low noise.

在减速机家族中，行星减速机以其体积小，reducer采购，减速范围广，精度高等诸多有点，而被应用于伺服、步进、直流等传动系统中。其作用就是在保证精密传动下，主要被用来降低转速*扭矩和降低负载/电机的转动惯量比。

In reducer family， planetary reducer is applied to servo，reducer， step and DC tran*issi*ystems because of its *all volume， wide range of deceleration and high accuracy. Its role is to ensure the precision drive， mainly used to reduce the rotational speed to increase the torque and reduce the load / motor inertia ratio.
