ABSTRACT:
Power-transmission sheaves conventionally include a centrally-open and shaft-engageable hub portion surrounding a directionally transversely extending hub-axis and together with at least one grooved belt-training portion that is surroundably connected to the hub portion and that provides a grooved outward periphery for the sheave. The at least one belt-training portion includes transversely separated flanged sides for the belt-training groove. Such conventional power-transmission sheaves are given enhanced belt engagement by providing one, or preferably both, of the flanged sides with a plurality of transversely extending openings therethrough.
