Abstract
A power transmission device for utility machinery is disclosed, the device including: a) a sleeve supporting a first sheave member having a first face; b) a hub received through the sleeve and moveable axially in relation thereto, the hub supporting a second sheave member having a second face that opposes the first face such that the first and second faces define therebetween a groove adapted to receive a belt and relative axial movement between the sleeve and the hub being adapted to vary at least one of pitch diameter and grip imparted to the belt from the sheaves; and c) an actuator mechanism adapted, through control of relative axial displacement between the sleeve and the hub, to vary at least one of the pitch and grip, the actuator mechanism comprising a control rod disposed substantially perpendicularly to the line of action of the axial displacement and connected to the hub through a link mechanism, the control rod being adapted to rotate and the link mechanism being adapted to translate rotation of the control rod into linear movement for relative axial displacement of the hub.
