减速机一般用于低转速大扭矩的传动设备，把电动机、内燃机或其它高速运转的动力通过减速机的输入轴上的齿数少的齿轮啮合输出轴上的大齿轮来达到减速的目的，普通的减速机也会有几对相同原理齿轮达到理想的减速，大小齿轮的齿数之比，就是传动比。Reducerisgenerallyusedindrivingequipmentoflowspeedhightorque,largegeargearoutputshaftpowermotor,internalcombustionengineorotherhighspeedrunningthroughthereducerinputshaftlessnumberofteethonthereducertoachievethepureofgeneralreducerwillh***eseveralpairsofthesameprincipletoachievetheidealeffectofgearreducer.Thesizeofthenumberofteethofthegearratio,thetran***issionratiois.在减速机家族中，行星减速机以其体积小，减速范围广，精度高等诸多有点，而被应用于伺服、步进、直流等传动系统中。其作用就是在保证精密传动下，主要被用来降低转速增大扭矩和降低负载/电机的转动惯量比。Inreducerfamily,planetaryreducerisappliedtoservo,stepandDCtran***issionsystemsbecauseofits***allvolume,widerangeofdecelerationandhighaccuracy.Itsroleistoensuretheprecisiondrive,mainlyusedtoreducetherotationalspeedtoincreasethetorqueandreducetheload/motorinertiaratio.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.)
