ABSTRACT:
A variable diameter pulley and belt drive has a torque and pitch radius sensitive squeeze control. The variable diameter pulleys are interconnected by a flexible belt or chain. The input pulley is connected to a power source through a pair of meshing gears and a floating link. A hydraulic control mechanism establishes the desired diameter ratio of the pulleys while the floating link is responsive to the torque transmitted to adjust the center distance between the pulleys and establish the squeeze force on the belt.
