ABSTRACT:
A V-belt variable-speed drive has a driving shaft; a stationary sheave fixedly mounted on the driving shaft; a sliding sheave assembly including a sliding sheave facing the stationary sheave and a casing covering the backside of the sliding sheave and designed to slide in the axial direction of the driving shaft, though normally urged to be set apart from the stationary sheave; self-sliding bearings for mounting the sliding sheave and casing on the driving shaft; a rotation-transmitting unit fixed to the driving shaft to transmit its rotation to the sliding sheave assembly while allowing the sliding sheave assembly to slide in the axial direction of the driving shaft; and a sliding sheave assembly-displacing unit for steplessly varying the rotating speed of a driven shaft by adjusting an interval between the stationary and sliding sheaves and regulating the radial position of the V-belt lying between both sheaves in accordance with the rotating speed of the driving shaft, wherein application of the self-aligning type bearings enables the sliding sheave assembly to be smoothly shifted in the axial direction of the driving shaft even when the V-belt applies a localized reaction force to the sliding sheave.
