Abstract

A roller coupling apparatus for securing rods and other threaded components together in a pumping system. The roller coupling apparatus can include a body with a plurality of radially-positioned wheels rotatably coupled to the body. The arrangement of the wheels can uniformly spread the rod load within the interior diameter of the tubing. The body can include flat outer surfaces to facilitate increased fluid flow capacity around the apparatus. In operation, the wheels contact and roll along the interior diameter of the tubing, preventing surface-to-surface wear of the coupling body exterior and tubing interior, thereby prolonging coupling and tubing life. In one embodiment, the wheels can include wear grooves that can indicate wear areas in the wellbore. In one embodiment, the body can include grooves to permit retrieval of the apparatus when needed. Multiple apparatuses can be utilized to form rod strings of various lengths.
