摘　　要：本文讨论了齿形链和渐开线齿形链轮的啮合原理，提出了用齿形角为３０°、周节等于或接近齿形链节距的刀具，通过计算出的相应负变位系数来加工，可以得出要求的渐开线齿形链轮。这种方法可以减少刀具数量，使齿形链和渐开线链轮的设计方案多样化。This paper discussed the engaging principie of tooth shaped chains and involute tooth formed SProckets,Put forward a manufactuping method that the required involute tooth formed sprockets can be obtained by the use of a cutter with a 30° profile angle and its pitch equals or approaches to the pitch of tooth shaped chain and a corresponding negative modiification coefficient prodced by means of calculation. This kind of method can reduce the number of cutters and mades a diversification on designing schemes of tooth shaped chains and involute sprockets.
