减速器的种类繁多，按照传动类型可分为齿轮减速器、蜗杆减速器和行星齿轮减速器；为保证受力均匀，先将任意对角位置的安装螺栓旋上，但不要旋紧，再旋上另外两个对角位置的安装螺栓***后逐个旋紧四个安装螺栓。按照传动级数不同可分为单级和多级减速器；按照齿轮形状可分为圆柱齿轮减速器、圆锥齿轮减速器和圆锥－圆柱齿轮减速器；按照传动的布置形式又可分为展开式、分流式和同轴式减速器。
There are many types of reducer according to tran***ission type can be divided into gear reducer, worm reducer and planetary gear reducer; according to tran***ission series can be divided into single and multi-stage gear reducer; according to the shape can be divided into cylindrical gear reducer, bevel gear reducer and cone - cylindrical gear reducer; according to the arrangement the form of tran***ission can be divided into expansion, split and coaxial reducer.
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 is match. Here is the size and fit tolerance of the motor"s locating lug, input shaft and reducer groove.
当选用斜齿轮减速机时有以下几点需要注意：
允许输入轴径：减速机的输入轴孔与电机输出轴一般是通过一个厚度可以变化的套环来连接的。当不加套环时减速机输入轴孔为高值。
When choosing a helical gear reducer, there are several points to be paid attention to:
Allowable diameter
The input shaft of the reducer and the output shaft of the motor are generally connected by a sleeve that can be changed by a thickness. The input shaft hole of the reducer is the maximum when the ring is not added.
