Patent

CA 2506558

A molten metal pump shaft coupling system for use in the coupling or connection of elongated shafts to other components and equipment, and for the disconnection thereof. A coupling (100) with internal discontinuous threads (105) may be coupled with an externally threaded shaft, with either continuous or discontinuous threads. Aspects of the invention include multiple external threads which may be pitched to accomplish a quicker and more efficient disconnect system. Furthermore, a shaft removal system is provided which provides two points of contact to assist in rotating a broken shaft end out of a coupling (100).

L'invention concerne un système d'accouplement d'axe de pompe en métal fondu destiné à coupler ou à raccorder, et à désaccoupler des axes oblongs aux autres composants et à l'équipement. Un accouplement avec des filets discontinus internes peut être couplé à un axe extérieurement fileté, avec des filets continus ou discontinus. Des modes de réalisation de l'invention comprennent des filets externes multiples pouvant comporter un pas permettant de disposer d'un système plus rapide et plus efficace de débranchement. En outre, l'invention concerne un système de déplacement d'axe qui fournit deux points de contact aidant à tourner une extrémité cassée d'axe hors d'un accouplement.
