允许输入法兰：不能大于或小于临级减速机的标准尺寸，如减速机PLE80?的标准法兰为80mm,其临级的减速级是PLE60?和PLE120，PLE80?允许法兰不应小于60mm,也不能大于120mm。AllowinputflangeItcantbegreaterthanorlessthanthestandardofthereducer.Forexample,thestandardflangeofreducerPLE80is80mm,andthedecelerationstageofitsreducerisPLE60?Reducegeardeflection,reducenoiseexcitation,therebyreducingtran***issionnoise。PLE120,PLE80?Themaximumallowableflangeshouldnotbelessthan60mm,norgreaterthan120mm.减速机的作用1)降速同时提高输出扭矩，扭矩输出比例按步进电机输出乘减速比，但要注意不能超出减速机额定扭矩。2)速同时降低了负载的惯量，惯量的减少为减速比的平方。大家可以看一下一般电机都有一个惯量数值。Thefunctionofthereducer1)reducethespeedandincreasetheoutputtorqueatthesametime.Theratioofthetorqueoutputtothemultiplyinganddeceleratingratioofthesteppermotoroutput,butwemustbecarefulnottoexceedtheratedtorqueofthereducer.2)speedreducesinertiaofloadatthesametime,andinertiareducestothesquareofdecelerationratio.Asyoucansee,generalmotorsh***eaninertiavalue.减速机动力源运转速度根据在不同转速条件下对减速机的试验表明，随着减速机输入转速的增加，噪声也将增大。Theexperimentalstudyonthestructuralformofthereducerboxshowsthatthecylindricalboxisadvantageoustovibrationreduction.Underthesameotherconditi***,thenoiselevelofthecylindricalboxis5dBlowerthanthatofothertypesofboxon***erage.)
