ABSTRACT:
A belt drive comprising a toothed belt and a toothed pulley. The belt is provided with a guide rib that extends in the longitudinal direction of the belt and traverses the teeth thereof. To provide lateral guidance of the belt on a toothed pulley, the guide rib engages an annular groove on the periphery of the pulley. Disposed on the base of the annular groove of the pulley is an insert that is made of a material that has a softer resilience than does the material of the belt. The radial height of the insert is such that when the toothed belt runs up onto the toothed pulley, the guide rib of the belt first contacts the soft-elastic insert, and only after radial compression of the insert do the belt teeth rest upon the corresponding surfaces of the toothed pulley.
