剃齿刀用钝后,每经过一次刃磨,相对于剃削某一特定参数的齿轮而言,其剃削啮合角便变小一次,显然剃削中心距也在变小。为了避免刀顶与齿轮根部发生干涉,剃刀的外径要相应地磨去△Deg,关于△Deg的数值,刀具设计手册中采用定量磨去法给出,即齿厚磨去一个定量,外径也相应地磨去一个定量。我们 Shaving a blunt knife, with each sharpening, relative to the shaving a particular parameter of the gear, the shaving angle of engagement will become smaller once, apparently shaving center distance is also smaller. In order to avoid the blade top and the gear root interference occurs, the razor’s outer diameter should be worn to the corresponding Deg Deg, △ Deg on the value of the tool design manual is given by the quantitative grinding method that the tooth thickness mill to a quantitative diameter Also wear a quantitative amount. we
