刀倾半展成法加工抓齿锥齿轮及准双曲面齿轮,是一种高生产率的先进方法。美国Gleason公司给它们的代号为SFT及HFT。这种方法的特点是,齿轮副中的大齿轮用成形法加工,切齿时没有展成运动,大轮齿面就等于切齿刀盘的刃锥面,和它啮合的小轮齿面则用展成法加工。 大轮的齿面既已确定 Knife tilting half of the law into the tooth bevel gear and hypoid gear, is a high productivity of advanced methods. US Gleason company to give them the code-named SFT and HFT. The characteristic of this method is that the gearwheel in the gear pair is formed by the forming method without any movement during gear cutting, the tooth surface of the large gear is equal to that of the cutting edge of the cutterhead, and the surface of the small gearwheel engaged with it is used Processing method. Large tooth surface has been identified
