各位老师, 国外客户要给光杆闸阀配AUMA电装,需要我们提供蜗轮速比(Reduction ratio ),同时也要提供Reduction factor, 这个是指蜗轮的什么参数? 谢谢先。

好像都是减速比的意思啊.....

蜗杆转一周,齿轮一个齿。齿轮转一周需要蜗杆转多少周,即是,速比。 那洋文说的是模数么? 这种配置的执行机构都是要厂家匹配的啊,是变速器你出?其它老外出?不解。 如果是你的变速器,把变速器标牌发给他就是了,上面的数据都有的,供参考。

前者是减速比的意思,后者不是

我们技术说reduction factor 可能是蜗轮箱扭力损失系数,后经国外确认确实是,比如100N-M蜗轮箱作用到阀门上的作用80N-N,那就是0.8

感谢你的及时回复,让我又明白了这个参数的具体含义!

闸阀采用丝杆传动,在大口径或高压力的情况下,需要大扭矩的输入装置,将电装的扭矩转化为丝杆推力,为减小电动输入装置,一般采用齿轮减速机增大电装输出扭矩,降低电装采购成本,具体选择减速机速比,需要参照阀门最大需要的推力,一般情况下减速机速比在3-7中间,具体可以联15333832617相互学*:)

机械效率, 0.25-0.3 伞齿轮箱 0.8-0.85
