Abstract

PURPOSE: To prevent the inclination of a V-belt in a speed changer and avoid a decrease of its efficiency, by eliminating occurrence of a shift between pulleys at input and output sides.
CONSTITUTION: Widths of variable-width V-shaped spaces 13, 23 are adjusted respectively by driving movable flanges 3, 4, 40 with the respective hydraulic servos actuated on oil chambers 10, 100, and this causes the part of a V-belt 9, that moves in contact with pulleys A, B, to adjust its rotating radius permitting the operation of stepless speed change. Here, with a change of width of the variable pulley B caused by the driven flange 40, the center of the pulley B is axially shifted. In accordance with said shift of the center, misalignment of positions is axially caused between the pulleys A and B to deform the V-belt 9. The restoring force against this deformation produces the axial side force in the pulleys A, B. Then the pulley A can be axially slid freely and further with an equal shaft of the hydraulic pressure applied to the flanges 3, 4, resulting in the simultaneous movement of the flanges 3, 4 up to the position where the side force is cancelled.
