本文对插齿刀加工的牙嵌离合器的齿形与接触情况进行了分析,并提出其几何设计与强度设计的方法。这种牙嵌离合器的加工与设计是西德Lorenz公司的技术秘密,本文破析了此项技术。与普通的刨削或铣削牙嵌离合器相比较,这种离合器有较高的精度与劳动生产率,同时,由于其轮齿是鼓形接触,它的强度和寿命也有显著的提高。 In this paper, the tooth profile and contact condition of gear claw in gear shaper machining are analyzed, and the methods of geometric design and strength design are put forward. The machining and design of this jaw clutch is the technical secret of Lorenz in West Germany. This article analyzes this technology. Compared with ordinary planing or milling claw clutch, this clutch has higher accuracy and labor productivity, at the same time, because of its teeth is drum-shaped contact, its strength and life expectancy also significantly improved.
