introduction： Worm gears are generally made of tin bronze，Paired worm materials are commonly used45Steel hardened toHRC45one55,Still in common use40C:hardeningHRC50one55，Grinding to finish by worm grinderRaO.8fcm,When the reducer is running normally，The worm is like a hardened“file”，File away the worm wheel，Cause the worm gear to wear。Generally speaking，This wear is slow.，Like a factory some reducer can be used10Years or more。If the wear rate is faster，It is necessary to consider whether the selection of the reducer is correct，Whether there is overload operation，Material of worm gear，Assembly quality or use environment and other reasons。
