ABSTRACT:
A bi-rotational coupling system that provides separate transmission components for the weight forces and the torque forces and allows rotation in either direction without decoupling. The weight support component provides vertical connection of rotating members. The torque transfer component, that is functionally independent from the weight support component, provides for transmission of the torque forces between the rotating members. A stabilizer that has a plurality of protrusions extending therefrom prevents contact between the coupler and rotating members and the surrounding tubing. Functionally applying this apparatus affords a method of providing bi-rotational coupling and of reducing component wear.
