Ball joint with spherical rollers
Abstract:
A ball joint which uses spherical rollers to reduce the torque friction which tends to inhibit the rotation of the ball within a ball joint assembly. Two sets of spherical rollers are captivated between the ball and two liner rings in the ball joint housing. The ball has two annular raceways which act as the inner raceways for the spherical rollers. Two liner rings have internal diameters which match the configuration of the spherical rollers and which act as outer raceways for the spherical rollers. The two liner rings have external threads and are installed into the housing which has matching internal threads.
