ABSTRACT:
A mud motor universal joint assembly that includes a pair of adjacent cylindrical joints having threaded connection means at one end and interlocking jaws at the other, each cylindrical joint having an internal blind tapered bore within the interlocking jaw portion containing a hard cylindrical load bearing member. The two joints are connected by a hardened cylindrical rod member inserted into the internal blind tapered bore of each joint and retained therein by perpendicular retaining pins. The joints, connecting rod, and bearing members are surface hardened to improve wear. No balls or seals are required and the internal hardened connecting rod and bearing members are easily replaced if necessary at a nominal cost.
