齿轮减速机的承载能力高，使用寿命长（前提是定期有做保养）；相比其他减速机，齿轮减速机要大很多，空间较小，抗震性能不好，齿根易断裂。齿轮减速机一般用于低转速大扭矩的传动设备，把电动机，普通的减速机也会有几对相同原理齿轮达到理想的减速效果，大小齿轮的齿数之比，就是传动比。
一、齿轮减速机的优点
1.齿轮采用高强度低碳合金钢经渗碳淬火而成，齿面硬度达HRC58-62，齿轮均采用数控磨齿工艺，精度高，接触性好。
2.传动率高：单级大于96.5%，双级大于93%，三级大于90%。
3.运转平稳，噪音低。
4.体积小，重量轻，使用寿命长，承载能力高。
5.易于拆检，易于安装。
二、齿轮减速机的缺点
相比其他减速机，齿轮减速机要大很多，空间较小，抗震性能不好，齿根易断裂。
