引 言 爪块离合器是某些机械传动中的一个组成部分,是由两个带爪齿的半离合器组成的。扭矩是通过爪齿啮合来传递的。因为它具有尺寸小,结构简单,没有相对滑动等优点,所以在机械制造中被广泛采用。然而,爪块离合器在机械制造加工时,往往由于批量少,单件生产多,在精密机床上加工 Introduction Claw clutches are an integral part of some mechanical transmissions and consist of two half-clutches with claws. Torque is transmitted through the claws. Because of its small size, simple structure, there is no relative sliding and so on, so in machinery manufacturing is widely used. However, claw clutches in the mechanical manufacturing processing, often due to the small batch, more than a single piece of production, processing in the precision machine tools
