Abstract

A clutch includes a throw arrangement configured to use radial motion of one or more throws for transmission of power via the clutch to a driven element. The clutch may convert radial motion of the throws into axial motion of some clutch components. This axial motion causes one or more friction elements to engage so as to transmit power to a driven element. The clutch may include one or more biasing elements which resist outward radial motion of the throws. The biasing element or elements may provide a desired time lag and/or a desired number of revolutions of the throw assembly between power being applied to the clutch and power being transmitted to the driven element. An adjustment element may be provided to allow alteration of a clearance within the clutch in order to allow adjustment of a time lag between power being applied to the clutch and maximum power being transmitted to the driven element.
