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。Therearemanytypesofreduceraccordingtotran***issiontypecanbedividedintogearreducer,wormreducerandplanetarygearreducer;accordingtotran***issionseriescanbedividedintosingleandmulti-stagegearreducer;accordingtotheshapecanbedividedintocylindricalgearreducer,bevelgearreducerandcone-cylindricalgearreducer;accordingtothearrangementtheformoftran***issioncanbedividedintoexpansion,splitandcoaxialreducer.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。Beforeinstallation,confirmwhetherthemotorandreducerareingoodcondition,andstrictlycheckwhetherthesizeofeachpartofthemotorconnectedtothereducerismatch.Hereisthesizeandfittoleranceofthemotorslocatinglug,inputshaftandreducergroove.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。Whenchoosingahelicalgearreducer,thereareseveralpointstobepaidattentionto:AllowablediameterTheinputshaftofthereducerandtheoutputshaftofthemotoraregenerallyconnectedbyasleevethatcanbechangedbyathickness.Theinputshaftholeofthereduceristhemaximumwhentheringisnotadded.)
