Abstract
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.
