ABSTRACT:
A spherical bearing assembly having an inner race member and an outer race member, the inner surface of the outer race member being a concave spherical surface, the outer surface of the inner member being a complementary convex spherical surface, the inner member including a spool member having a first threaded portion disposed on its outer surface and at least two spherical segments, each segment having a second threaded portion on its inner surface complementary to the said first threaded portion on the outer surface of the said spool member, the said segments disposed on and interlocked with the said spool member by the meshing of the said complementary first and second threaded portions, the said spool member's axial length is somewhat greater than the axial length of the said bore such that the said spool member, when threaded in a meshing relationship with the said spherical segments, a portion of the said threaded spool will extend beyond the lateral faces defined by the spherical segments, the said extension of the said spool member being adapted to receive a threaded nut-like member to further lock the said spool member and the said spherical segments in their respective operational positions, the improvement comprising the provision of a conical recess on the said nut member on the side thereof abutting the said spherical segments, the angle of the said conical surface of said recess being substantially tangential to the outer convex spherical surface of the said inner member.
