Vane adjustment mechanism for the infinitely variable adjustment of a rotational speed under load
Vane adjustment mechanism for the infinitely variable adjustment of a rotational speed under load, in which vanes are attached radially or axially to a holding disc connected to the input shaft and engaged pawl-fashion in a toothed ring connected to the output shaft. By variation of the spacing between the holding disc and the toothed ring, the vanes produce, by virtue of the skewed position which arises, a rotary motion at the toothed ring. It is thus possible for a predetermined rotational speed to be reduced in an infinitely variable manner and under load down to zero or increased by up to about twice the original figure, depending on the design.
