在一般情况下铣削双圆弧齿形的链轮都是利用成型刀具,但是铣制链轮的数量不多,而在一般的工厂制造一把如图1所示的成型链轮铣刀(或滚刀),既困难,成本又高。我厂在试制蛇皮抛光机时,需要制造一对齿数Z=18,节距P=15.875毫米,齿沟圆弧半径R=5.13毫米,滚子外径d_r=10.16毫米,齿头的半径R=47.6毫米的链轮,因无专用设备,所以,我们利用普通铣刀来代替成型刀具铣制链轮,实践证明是完全可行的。加工
In general, double circular arc profile sprocket milling is the use of forming tools, but the number of milling sprocket is not much, and in the general factory to create a molding sprocket cutter shown in Figure 1 (or Hob), both difficult and costly. I plant in the preparation of snake skin polishing machine, you need to create a pair of teeth Z = 18, pitch P = 15.875 mm, tooth groove radius R = 5.13 mm, roller outer diameter d_r = 10.16 mm, the radius R = 47.6 mm sprocket, because there is no special equipment, so we use the ordinary milling cutter instead of molding tool milling sprocket, proved to be entirely feasible.
