Abstract
A belt drive clutch having a hexagonal sleeve splined on a power output shaft and carrying an outer sheave disc. A drive belt supporting annulus is freely rotatable on the sleeve and located between the outer sheave disc and an inner sheave disc. The inner sheave disc has a stud shaft extending inwardly and having a hexagonal bore matching the hexagonal external conformation on the sleeve. Ball bearings are assembled on the stud shaft and a clutch control ring is assembled on a peripheral race of the ball bearing. A camming arrangement shifts the clutch control ring axially to engage or disengage the belt by optionally constricting or expanding the space between the outer and inner sheave discs.
