摘要： A universal joint (U-joint) assembly transmits torque from a drive component to a driven component across an articulating joint. The U-joint assembly includes male and female U-joint members, a central ball joint, and a retaining device configured to secure the assembly in an assembled configuration. The female U-joint member includes a cavity extending into a receptacle end thereof. The cavity terminates in a circular receptacle and includes four flat surfaces extending longitudinally therefrom at 90-degree intervals. The male U-joint member has a drive end with four multi-angled surfaces extending longitudinally from the drive end at 90-degree intervals about a periphery of the drive end. When in an assembled configuration, each of the multi-angled surfaces of the drive end of the male U-joint member opposes a corresponding one of the four flat surfaces of cavity of the female U-joint member. Other embodiments are also disclosed.

摘要： A universal joint carried by an elongate body having an axis. The universal joint has an inner race that pivots omni-directionally within an outer race and a series of first and second opposed cavities formed in the inner race and the outer race. There are a plurality of torque transfer elements, each torque transfer element having a first portion that engages a first cavity and a second portion that engages a corresponding second cavity. The first cavity is a socket that permits rotation of the first portion within the first cavity as the inner race pivots omni-directionally within the outer race and the second cavity is a track oriented in the direction of the axis of the elongate body. The second portion moves along the track as the inner race pivots omni-directionally within the outer race of the second portion along the track. The second portion has at least one drive surface that engages an inner surface of the track at more than one point along the direction of the track.

摘要： A universal joint for transmitting driving torque between rotative members including an inner joint member for connection to one of the rotative members and an outer joint member for connection to the inner joint member and to the other of the rotative members. The inner joint member swivels within the outer joint member by virtue of contacting inner and outer spherical surface portions on the outer and inner joint members, respectively. Torque is transmitted between the inner and outer joint members by a plurality of roller balls which extend between a recess in the inner joint member and a plurality of circumferentially spaced-apart rectilinear recesses in the outer joint member which are disposed between the spherical inner surface portions on the outer joint member. The recess in the inner joint member permits the spherical roller balls to come into contact with one another, and the rectilinear recesses in the outer joint member permit the roller balls to separate when the inner and outer joint members articulate with respect to one another.
