Abstract
A ball pivot thrust bearing flex joint assembly having an inner race member and an outer race member, the inner surface of the outer race member being a concave spherical self lubricating surface which provides a maximum envelopment of the complementary convex spherical outer surface of the inner pivoting ball race. The inner race ball is provided with a through aperture along the axis of primary motion for acceptance of a through shaft or bolt, and is provided with integral lateral extensions which are necked down to provide clearance for secondary axis motion. The end portions of the through hole aperture are provided with self lubricating bearings which support the radial loads and accommodate main axis rotation. Flat, washer type, self lubricating bearings are provided between the ends of the inner race pivoting ball and the associated clevis. Thus high thrust loads are accommodated with limited secondary axis motion about the complementary spherical surfaces and primary motion is accommodated about the shaft or bolt center line radial bearings.
