  • Patent number: 6685571
    Abstract: My universal joint will use the outer and inner members to hold the balls in alignment. The male or female part would hold the ball in a half spherical recess and the other component would have a race groove to allow movement. It will also have means of attachment on each end with both ends being integral components of the final product. The male and female components could be made out of a pipe, tube, bar or cylinder of any length desired. The male component could consist of the unit holding 3 balls. This method would turn the friction wear of a rubbing surface into a rolling movement that would allow more speed of motion and less vibration. If necessary, in order to provide more bearing surface, increase torque, speed and reduce vibrations, it would be possible to use several paired ball tracks and ball seats. The center ball would impart rolling movement to all balls in contact with the ball race.
