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.对减速机箱体进行共振测试，找出共振位置，增加适当的筋条（板），可以提高箱体的刚度，减少箱体的振动，实现降噪。多级传动时要求瞬时传动比的变化尽量小，以保证传动平稳，冲击及振动小，噪声低。Bytestingtheresonanceofthereducerbox,findingouttheresonanceandaddingappropriateribs(plates),thestiffnessoftheboxcanbeincreased,thevibrationoftheboxcanbereducedandthenoisecanbereduced.Inmultistagetran***ission,thechangeofinstantaneoustran***issionratioshouldbeas***allastoensurestabletran***ission,lowimpactandvibration,andlownoise.)
