ABSTRACT:
A continuously variable belt transmission of the type comprising: primary and secondary pulleys, each of which comprises a pair of axially opposed sheaves supported on a shaft, one of the sheaves being movable and the other being fixed; a belt wound around these pulleys; a pressure adjusting mechanism for imparting to at least one of these pulleys an axial force which corresponds to torque transmitted; and mechanical actuators for axially shifting the movable sheaves of these pulleys, wherein: first thrust bearings are respectively interposed between the backsides of the movable sheaves and one ends of the mechanical actuators; a first automatic aligning mechanism is provided for supporting at least one of the races of each the first thrust bearing; and axial forces occurring at the pulleys are carried by the shafts directly, or via the first thrust bearings, the first automatic aligning mechanisms and the mechanical actuators, or via the pressure adjusting mechanism.
Further, adjustable intermediate members are provided which abut against the other ends of the mechanical actuators and are radially supported on shoulders of a casing, the adjustable intermediate members being adapted to rotatably support the shafts, and wherein second thrust bearings are interposed between the backsides of the adjustable intermediate members and a flange formed on one end of the shaft, at least one of the races of each the second bearing being supported by a second automatic aligning mechanism.
