在小型齿轮(Df<200mm)滚切加工中,对现有的滚齿机床供料加以改造,能提高生产效率、并减轻劳动强度。加工m=3,Df=90mm圆柱直齿轮时,自动循环过程见附图所示。上道工序加工完的齿坯,直接沿供料槽7滚入交换轮5的夹料槽4a中。将夹料槽4a、4b、4c、4d的滚动面设计成楔形(自锁角5°～7°),滚入的齿坯自行停止在夹料槽中,并发出讯号(压触行程开关)。接着交换轮5沿箭头方向回转
In the small gear (Df <200mm) hobbing process, the existing gear hobbing machine to be modified to improve production efficiency and reduce labor intensity. Processing m = 3, Df = 90mm cylindrical spur gear, the automatic cycle shown in the drawings. The tooth blanks processed in the previous process directly roll into the trimming slot 4 a of the exchange wheel 5 along the feeding slot 7. The rolling surfaces of the clamping grooves 4a, 4b, 4c, 4d are designed as wedges (self-locking angle 5 ° ~ 7 °), the rolled gear blank stops itself in the clamping groove and sends out a signal (pressure stroke switch) . The exchange wheel 5 then swivels in the direction of the arrow
