Re: 大虾们帮忙看一下这个齿轮的参数有无问题

二楼参数输入有误，不知道如何更改，一楼和三楼为正确参数

Re: 这个齿轮的参数有无问题---[请教]

Addendum和Dedendum是从分度圆开始计算的。齿轮变位的话，那数据就不会是标准的。变位体现在齿厚的数据上。一号齿轮是正变位的（齿厚比标准的大），所以齿顶高比较大。齿根就比较浅。二号齿轮有点负变位（齿厚比标准的小），所以齿顶高有点小，齿根就比较深。我想你三楼的dedendum是多了个零。

Re: 这个齿轮的参数有无问题---[请教]

<P>谢谢，第二个齿轮是多输了个零，也就是说齿轮参数没有问题，但是不是标准齿轮，不能按以下公式来算的意思了？？？</P>

Re: 这个齿轮的参数有无问题---[请教]

正齿轮是指0变位齿轮，在专业做齿轮的企业中，很少碰到。
你提供的公式不适用于你的两个齿轮。

Re: 这个齿轮的参数有无问题---[请教]

那变位齿轮该怎么计算才对？

阿松 发表于 2007-4-20 15:39:34

Re: 这个齿轮的参数有无问题---[请教]

齿顶高一般是加上变位量（变位系数乘以模数），齿根高减去变位量。但实际上齿顶圆是车削加工的，通常可以根据设计者的要求较随意的确定，齿根可以根据配对齿轮的齿顶和顶隙以及中心距来计算，如果没有特别要求的话，可以根据已有的刀具来设计，以节省成本，这样齿顶可以根据齿根来定。
