为解决设备维修、技术革新、产品试制中单件小批加工蜗轮的问题,我们设计制成一种在 Y38滚齿机上用飞刀展成蜗轮的简易装置。如图,机床刀架头架经莫氏5~*锥套1上的安全离合器带动与之用花键滑配合的刀杆4转动,并由刀杆另一端滑配合着的滑键9,经齿数为27、20、21、28的齿轮Ⅰ、Ⅱ、Ⅲ、Ⅳ, In order to solve the problem of single-piece machining of worm gear in equipment maintenance, technological innovation and product trial, we designed a simple device for developing a worm gear with a flying knife on a Y38 gear hobbing machine. As shown in the figure, the headstock of the machine tool turret is driven by the safety clutch on the sleeve 1 of Morse ’s 5 ~ * to rotate with the knife bar 4 matched with the spline slip and the sliding key 9 which is matched with the other end of the knife bar. Gear number of 27,20,21,28 Gear Ⅰ, Ⅱ, Ⅲ, Ⅳ,
