Patent

CA 2311895

The stator, rotor and/or flex shaft of a progressive cavity motor is made up of composite materials, e.g., fiberglass and resin, in a variety of combinations with and without bonded resilient elastomers. The composites are formulated to provide resiliency and non-resiliency where needed. The flex shaft between the rotary power source and the rotor is made of composite materials and designed to absorb the orbital and gyrational movement of the rotor.

Le stator, le rotor, et/ou l'arbre flexible d'un moteur à cavité intermédiaire sont fabriqués dans des matériaux composites, par exemple des fibres de verre et une résine, selon diverses combinaisons avec ou sans élastomères agglomérés, ces composites étant par ailleurs formulés pour conférer souplesse ou rigidité aux endroits voulus. L'arbre flexible, situé entre la source d'alimentation rotative et le rotor, est fabriqué dans des matériaux composites et conçu pour amortir les mouvements orbital et giratoire dudit rotor.
