Abstract
A spherical bearing includes an outer member having a hole extending from side to side, the surface of the hole being concave and spherical so that the outer member has constricted portions at each side. The outer member also has a walled keyway extending downward from the hole and extending axially from side to side of the outer member substantially perpendicular to the sides of the outer member; a walled key in the keyway is co-extensive with the keyway. The key also has a concave and spherical top surface corresponding to the surface of the hole so that the key has shoulder portions corresponding to the constricted portions of the outer member. A partially spherical inner member has flat sides, the inner member being held in the outer member by impingement of the spherical surface of the inner member against the constricted portions of the outer member and the key being held in the outer member by impingement of the shoulder portions of the key against the spherical surface of the inner member. A radial slot extends through the walled key. A resilient member disposed in the slot and abut the inner surface of each of the walls, with an adjusting member in the wall of the key to vary the width of the slot thereby varying the bearing tolerance between the inner and outer member and varying the degree of compression of the resilient member and therefore the degree of the preloading force exerted by the key member on the spherical surface of the inner member.
