ABSTRACT:
A spherical bearing comprising 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 having a ramped keyway extending diagonally downward from the hole; a ramped key in the keyway whose ramp is complementary with the ramp defining the keyway in the outer member, the key also having 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; and a partially spherical inner member, 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, adjusting means to move the key upwardly or downwardly on the respective ramps of the key and the keyway thereby varying the bearing tolerance between the inner and outer member.
