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；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；减速机与工作机的安装关系：为了避免工作机主轴挠曲及在减速机轴承上产生附加力，减速机与工作机之间的距离，在不影响正常的工作的条件下应尽量小，其值为5-10mm。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.
齿轮减速机具有体积小，传递扭矩大的特点。齿轮减速机在模块组合体系基础上设计制造，有***的电机组合、安装形式和结构方案，传动比分级细密，满足不同的使用工况，实现机电一体化。
Gear reducer has the characteristics of ***all volume and large torque tran***ission. Gear reducer is designed and manufactured on the basis of modular combination system. There are very many motor combinati***, installation forms and structural schemes. The tran***ission ratio is fine and classified to meet working conditi*** and achieve mechanical and electrical integration.
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, c***truction, 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.
