补充资料:刀具:滚刀
   刀齿沿圆柱或圆锥作螺旋线排列的齿轮加工刀具﹐用於按展成法加工圆柱齿轮﹑蜗轮和其他圆柱形带齿的工件(见齿轮加工﹑齿轮)。根据用途的不同﹐滚刀分为齿轮滚刀﹑蜗轮滚刀﹑非渐开线展成滚刀和定装滚刀等。
         齿轮滚刀 常用的加工外嚙合直齿和斜齿圆柱齿轮的刀具。加工时﹐滚刀相当於一个螺旋角很大的螺旋齿轮﹐其齿数即为滚刀的头数﹐工件相当於另一个螺旋齿轮﹐彼此按照一对螺旋齿轮作空间嚙合﹐以固定的速比旋转﹐由依次切削的各相邻位置的刀齿齿形包络成齿轮的齿形。常用的滚刀大多是单头(见螺纹)的﹐在大量生產中﹐为了提高生產效率也常採用多头滚刀。单头滚刀转一转﹐齿轮绕本身轴线转过一个齿﹔多头滚刀转一转﹐齿轮转过的齿数与滚刀头数相等。
         中小模数的滚刀在螺旋昇角小於5°时﹐常製成直容屑槽﹐便於製造和刃磨﹔螺旋昇角大的滚刀常製成螺旋容屑槽﹐以免刀齿的一侧刃以大负前角(见刀具)切削的不利情况。
         用高速钢製造的中小模数齿轮滚刀一般採用整体结构。模数在10毫米以上的滚刀﹐为了节约高速钢﹑避免锻造困难和改善金相组织﹐常採用镶片结构(图1 齿轮滚刀 )。镶片滚刀的结构形式很多﹐常用的为镶齿条结构﹐即刀齿部分用高速钢製成齿条状﹐热处理后紧固在刀体上。用硬质合金製造滚刀﹐可以显著提高切削速度和切齿效率。整体硬质合金滚刀已在鐘錶和仪器製造工业中广泛地用於加工各种小模数齿轮。中等模数的整体和镶片硬质合金滚刀已用於加工铸铁和胶木齿轮。模数小於 3毫米的硬质合金滚刀也用於加工钢齿轮。硬质合金滚刀还可加工淬硬齿轮(硬度为 HRC50~62)。这种滚刀常採用单齿焊接结构﹐製有30°的负前角﹐切削时刮去齿面的一层留量。
         国际标準把滚刀的精度等级分为 AA级﹑A级和 B级。为了加工特别精密的齿轮﹐有的国家还有AAA级滚刀。在切齿过程中﹐滚刀的製造误差主要影响齿轮的齿形误差和基节偏差。
         剃齿前加工齿轮齿形用的滚刀称为剃前滚刀。剃前滚刀的齿形﹐要按剃齿餘量形式的要求製成特殊的形状(图2 剃前滚刀的齿形 )。齿顶带凸角﹑齿根带倒角的滚刀齿形是一种较常用的留剃形式﹐它使被加工齿轮的齿根处有些根切﹐齿顶处有些倒角﹐中间部分剃齿餘量均匀。(见彩图 硬齿面齿轮的精加工刀具──硬质合金刮削滚刀 ﹑ 齿轮加工刀具──滚刀﹑插齿刀﹑剃齿刀 )
