Toothed belt Gearing

摘要

A toothed belt gearing includes a toothed pulley including pulley teeth having a first configuration and a toothed belt including belt teeth having a second configuration. The belt teeth are meshable with the pulley teeth, the first configuration and the second configuration being different from one another and being selected so as to minimize air present in tooth spaces between meshed ones of the belt and pulley teeth as compared to other toothed belt and pulley combinations which share a substantially same tooth configuration, thereby reducing noise radiation resulting from a resonance behavior of the toothed belt normally present in the other toothed belt and pulley combinations.
