Abstract

1487241 Expanding wheel gear AC CARS Ltd 6 Feb 1975 [6 Feb 1974] 05435/74 Heading F2D An expanding pulley driven by a V-belt 21, comprises fluid-actuated means, such as a cylinder 6 attached to one pulley flange 4, and containing a liquid such as oil, acting centrifugally on a piston 7, attached, as by a guide bolt 8, to the other pulley flange 3, to increase separation of the flanges with increase in speed, in opposition to a return spring 14. The speed of a driven shaft 2 on which the flange 3 is fixed is thereby increased with increase in speed of the shaft 2. Air is bled from each side of the piston 7 through passages 24 ... 27.
