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.
通常齿轮减速机已广泛应用于冶金、矿山、起重、运输、水泥、建筑、化工、纺织、印染、制药、等领域。但在这种齿轮减速机的使用有一定的限制，所以，让我们了解下使用时需要注意什么。
1、高速旋转不超过1500 r / min。齿轮减速器。
2、齿轮圆周速度不超过20 m / s。
Usually gear reducer has been widely used in metallurgy， mining， lifting， transportation， cement， ctruction，减速机厂家， chemical， textile， printing and dyeing， pharmaceutical， and other fields. But there are some restricti on the use of this gear reducer， so let us know what to pay attention to when using it.
1. The high speed rotation does not exceed 1500 R / min. Gear reducer.
2， the circumferential speed of the gear is not more than 20 m / S.
减速机内部齿轮变位系数选择 正确合理选择变位系数，减速机报价，不但可以凑合中心距，避免齿轮根切，保证满足同心条件，改善齿轮的传动性能和提高其承载能力及提高齿轮的使用寿命，减速机，还可以有效控制 侧隙、温升与噪声。
The change coefficient of gear displacement coefficient in the reducer is selected correctly and reasonably. It can not only make the center distance， **oid the gear cutting， meet the conditi， improve the tran**ission performance of the gear and improve its bearing capacity and improve the service life of the gear， but also can effectively the side gap， temperature rise and noise.
