ABSTRACT:
A universal joint assembly for transmitting a moment of rotation in both directions between two members comprising an outer joint element and an inner joint element, the joint elements have confronting spherical surfaces wherein one of the surfaces is smoothly spherical and the other surface has a series of generally axially extending circumferentially spaced grooves having flanks open at an angle, the joint assembly includes a plurality of rolling elements in the annular space between the confronting surfaces which engage in the grooves and a cage having a plurality of pockets disposed between the confronting surfaces of the joint elements for guiding the rolling elements. At least a pair of rolling elements are located in a common pocket of the cage and elastic preloaded member is disposed between the rolling elements in each pocket which is operable to press the rolling elements reciprocally in a peripheral direction against the related flank of the groove.
