苏联铣工佛罗洛夫同志设计出一种插齿头(图1),并把它装在滚齿机的滚刀架上,插齿头是这样的:轴1(图2)被插入在主轴的锥孔内,回转运动由主轴利用蜗轮传动2、3传给插齿刀4.当轴1转动时,回转运动同时又经过齿轮5和6,偏心臂7,连杆8和杠杆9而传给齿轮10,这时,齿轮10就来回摆动,而且,利用圆齿条11使插齿刀4作出往复运动。当插齿刀 Former Soviet Union Mill Frilov designed a socket gear (Figure 1) and attached it to the hobbed hob hob. The socket head was such that shaft 1 (Figure 2) was inserted into the cone of the shaft Hole, rotary motion from the spindle by the worm gear transmission 2 and 3 to the gear shaper 4. When the shaft 1 is rotated, the slewing motion at the same time through the gear 5 and 6, the eccentric arm 7, the lever 8 and the lever 9 to the gear 10, at this time, the gear 10 swings back and forth, and the rake gear 11 reciprocates the gear shaper 4. When shaper cutter
