ABSTRACT:
Cheeks (2, 3) in the form of a solid rim are made integral with a pulley body (1) in that their cylindrical inside surfaces (6) are fitted under tension against cylindrical surfaces forming the bottoms of grooves (7, 8). Their positioning is carried out either by hot-collaring or by driving onto conical surfaces (9, 10). The bottoms of channels contrived between teeth (4) communicate with the outer sides of the pulley, thus permitting the movement of air during operation with a notched belt (5) and, consequently, a reduction of operating noise.
