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.
Claims12
A bi-rotational coupling system comprising:
- a first rotating member;
- a second rotating member;
- weight support means for providing vertical connection of said first rotating member and said second rotating member;
- torque support means for transferring torque between said first rotating member and said second rotating member;
- said weight support means functionally independent from said torque support means so that said weight support means transfers substantially no torque forces and said torque support means transfers substantially no weight forces;
- and
- said first rotating member and said second rotating member capable of rotating either direction without decoupling.
