    • 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.
    • 一种用于在包括外接头元件和内接头元件的两个构件之间沿两个方向传递转动力矩的万向接头组件,所述接合元件具有相对的球形表面,其中一个表面是平滑球形的,另一个表面具有一系列 大致轴向延伸的圆周间隔开的凹槽,其侧面以一定角度打开,接头组件包括多个滚动元件,环形空间中的相互啮合在凹槽中的相对表面之间的环形空间,以及具有多个凹穴的保持架, 用于引导滚动元件的接头元件。 至少一对滚动元件位于保持架的公共凹槽中,并且弹性预加载构件设置在每个凹槽中的滚动元件之间,其可操作以沿圆周方向往复地将滚动元件按压在凹槽的相关侧面上。
