ABSTRACT:
A constant velocity universal joint is provided which employs bearing rollers with central cylindrical portions and groove-matching ends in place of balls. The universal joint has an inner race or member with outwardly-facing grooves spaced therearound, an outer race or member with inwardly-facing grooves therearound, and a cage between with openings. The rollers are retained in the openings with the cylindrical portions located at the openings and with the ends engaged in the grooves of the inner and outer races. The central cylindrical portions engage the cage at the openings in line contact rather than point contact, as with balls, resulting in less wear, longer life, and smooth operation. The ends engage the grooves in a manner somewhat similar to balls.
