一、前言对于某些仪表齿轮传动,要求有较大的侧隙。例如,对于定时器、时间继电器、水表、煤气表、电度表计度器以及各种机械计数器等,齿轮传动的法向侧隙应取为0.15m～0.30m(m为模数),对于某些用游丝消除空回的仪表齿轮传动,例如压力表中的齿轮传动,设计时所给的侧隙也是较大的。足够的侧隙是齿轮传动灵活,不发生卡滞现象的重要条件。对于塑料小模数齿轮传动这一点尤为重要。
First, the foreword For some instrument gear drive, requires a larger backlash. For example, for the timer, time relay, water meter, gas meter, meter and various mechanical counters, gear backlash should be taken from 0.15m ~ 0.30m (m is the modulus), for Some of the gauges to eliminate empty back gear transmission, such as pressure gauges in gear, the design given backlash is larger. Sufficient backlash is a gear transmission flexible, does not occur the phenomenon of jamming an important condition. This is especially important for small plastic gear drives.
