<p>A driven half of the universal joint has an axially outwardly opening tubular socket end in which an end of a driver half of the joint is slidably received; and a universal torque-transmitting coupling of shaft to socket, also accommodating axial change in position of those parts, is effected through a pair of like cushioned swivel sub-assemblies, each journaled by transverse pin and bushing means to the driver half end. The driven socket presents a specially shaped cavity defined by pairs of flat parallel, radially outwardly extending and laterally spaced wall surfaces on either side of the axis of socket rotation, between each of which surface pairs corresponding flat side surfaces of one of the swiveling and torque-transmitting sub-assemblies are received with a sliding fit. Thus said sub-assemblies act directly and torsionally on the output socket in transmitting driving power between the shaft members of the installation. Each such sub-assembly includes an annular cushioning washer of plastic presenting, radially outwardly of its flat side surfaces, a quasi-cylindrical convex surface, which arcuate surfaces have swiveling action as engaged with flat, axially extending and radially outer wall surfaces of the driven socket half. Steel sleeves encircle and confine the cushions of the respective sub-assemblies, being convexly arced flush with the outer surfaces of said cushions. Swiveling of the driver shaft and the sub-assemblies in a plane at 90 DEG to the direction of the swivel action just described takes place about the axis of the previously described pin and bushing means on the driver shaft end.</p> |
