Abstract
TITLE OF THE INVENTION VARIABLE SPEED TRANSMISSION DEVICE A variable speed transmission device of the type in which a first rotatable element is in rolling friction engagement with a second nutatable element having an axis movable in a biconical path about the axis of the first elements. The first element supports a pair of axially movable cone-like members fixed for rotation with the first element and each having exterior surfaces of revolution defined by a curved generatrix to be convex in axial section and converging away from the point of first and second element axes intersection. The rolling friction surfaces of the second element are defined by an interior cylindrical surface and means are provided for adjusting the angle of the second element axis with respect to the first to vary the radii at the point of frictional contact on the cone-like members. Angular adjustment of the second element axis with respect to the axis of the first element is accomplished in a preferred embodiment by fluid activators for adjustably eccentric journals on a third or support element, such journals being movable in diametrically opposite directions at opposite ends of the second element. Alternately, the angular adjustment is accomplished by an eccentric sleeve-like member carrying the second element in the support member. Input torque is preferably provided by a clutch to the support member whereas the variable speed output is desirably transmitted through a multi-speed gear transmission.
