摘　　要：通过对微型齿形链链轮齿廓形状的研究,得出其链轮齿形特点实际上是一种齿顶成整圆弧的负变位渐开线圆柱齿轮。利用渐开线齿轮啮合原理对渐开线链轮进行参数设计,并采用变压力角滚刀进行全切式加工,在保证齿形精度的基础上,实现了链轮齿顶圆弧过渡加工,结果表明:微型齿形链链轮可以通过特殊刀具实现高精度、低成本的滚齿加工。By analyzing the tooth profile of Mini silent chain, the property of this kind of gear is gotten, it is a negative modification coefficient cylinder gear with involve tooth profile and have whole arc in top tooth. The engagement theory of the normal gear can be used to study the silent chain, and hob with variable pressure angle are used to do the machine, result show the new method not only ensure the precision of tooth profile but also can decrease the cost.
