减速机是国民经济诸多领域的机械传动装置，行业涉及的产品类别包括了各类齿轮减速机、行星齿轮减速机及蜗杆减速机，也包括了各种专用传动装置，如增速装置、调速装置、以及包括柔性传动装置在内的各类复合传动装置等。
The reducer is a mechanical drive device in many fields of national economy, industry related product categories include all kinds of gear reducer, planetary gear reducer and the worm reducer, also includes a variety of special tran***ission device, such as accelerating device, device, and a flexible tran***ission device, tran***ission device, including various types of composite.
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.
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.
