现代机械传动中,齿轮机构是一种重要的传动形式。小模数齿轮传动广泛地应用在仪器仪表工业中。对于一些精度要求不太高的片齿轮(例如玩具上用的等),多半可以用普通冲裁的方法制造。但是,钟表和某些计测仪器上精度要求高的小模数齿轮,至今很少采用冲裁方法生产,尤其象0.3小模数精密片齿轮,则 In modern mechanical transmission, gear mechanism is an important form of transmission. Small modulus gear drive widely used in instrumentation industry. For some precision less demanding piece gear (such as toys used, etc.), most of them can be made using ordinary blanking. However, the accuracy of the clock and some measuring instruments on the small modulus gear, so far rarely used punching method of production, especially as 0.3 small modulus precision film gear, then
