在没有专用设备的条件下,加工渐开线弧形齿(图1)比较困难。我们采用在滚齿机上粗滚并留适当余量后,在Y38工作台上安装分度头与滚齿机配合操作(图2),完成了渐开线弧形齿的加工,加工费用也相应降低。将滚齿机刀架1转90°,齿轮铣刀10(m=6,6号)装夹在刀杆2上。平 In the absence of special equipment, the processing of involute curved teeth (Figure 1) is more difficult. We use the hobbing machine rough rolling and leaving the appropriate margin, the Y38 table mounted indexing head and hobbing machine with the operation (Figure 2), completed the involute curved tooth processing, processing costs are also reduced accordingly. The hobbing machine turret 1 rotated 90 °, gear milling cutter 10 (m = 6,6 number) mounted on the arbor 2. level
