ABSTRACT:
A belt-driven clutch system having a driven clutch with a particular arrangement of cam followers and cam slots. One embodiment of the invention is a clutch having a fixed sheave, a movable sheave and a housing mounted to the movable sheave. The housing has a cam slot with first and second cam surfaces. The clutch also includes a pair of cam followers that is secured to the fixed sheave for acting upon the cam surfaces of the cam slot. A first cam follower of the pair of cam followers acts upon a first cam surface of the cam slot and a second cam follower of the pair of cam followers acts upon the second cam surface of the cam slot to reduce backlash. The invention also provides adjustment of spring tension and belt width of the clutch without requiring removal or disassembly of the clutch.
