补充资料:剃齿刀
      齿面上开有许多形成切削刃的窄槽,按螺旋齿轮啮合原理加工工件的齿轮形齿轮加工刀具。在加工时,刀具从齿轮的齿面上切下胡须状的细切屑,故称剃齿刀。剃齿刀用于在滚齿、插齿(见齿轮加工)后对轮齿进行精加工。常用的盘形剃齿刀像一个淬硬的斜齿圆柱齿轮(图1),齿面上的沟槽有两种形式:一种是在整个齿圈上开有圆环形或螺旋形的通槽,槽的截面可以是矩形,也可以是梯形,这种剃齿刀用钝后只刃磨前面(槽部),齿形和外径都不改变,由于通槽不能做得太深,只适用于模数小于1.75毫米的剃齿刀;另一种为两侧面的沟槽不通,是用梳形插刀分别插出来的,为使插刀能够退刀,在每个齿的齿根处钻有倾斜的小孔。这种剃齿刀用钝后需重磨齿形和齿顶圆柱面。
  
  为了减小每个齿的切削负荷,剃齿刀的齿数较多,一般取质数,以避免与被切齿轮的齿数有公因数,否则剃齿刀的误差将复印到被加工齿轮上去。剃齿刀的精度按国际标准有AA级、A级和B级3种。在实际生产中,用正确的渐开线齿形的剃齿刀剃出的齿轮齿形,往往在齿轮的节圆附近偏离正确的渐开线,向内凹进,偏差约0.01~0.03毫米,直齿齿轮的齿形偏差要比斜齿轮大些。为了使工件得到正确的渐开线齿形,剃齿刀的齿形应经过修正,在大量生产中都是通过实验的方法来决定剃齿刀的齿形修正曲线。
  
  剃齿刀可以加工直齿和斜齿的内、外圆柱齿轮,生产效率高、加工表面光洁。此外,还有加工精密蜗轮用的蜗轮剃齿刀(图2),其基本蜗杆的类型和参数均应与蜗轮相匹配的工作蜗杆(见蜗杆传动)相同。它与齿轮剃齿刀一样,在螺旋面上开有许多窄的沟槽,以形成切削刃并容纳切屑。蜗轮剃齿刀难于制造,只有在加工精度要求很高的蜗轮时才使用。(见彩图)
