Gear-shaft linkage, especially for nuclear reactor coolant pumps

Creators

Description

The pump comprises: - inlet and outlet channels for the pumped fluid - a rotating shaft - a gear wheel mounted on the shaft by an axial locking nut which can support the axial hydraulic force - a thermal barrier above the gear wheel. A hydrostatic bearing fitted to the exterior surround of the gear wheel, the gear shaft linkage is made by at least a centering and locating device having a cylindrical span and an axial stop and another independent device which can take up the torque

Abstract (French)

L'invention est relative a une liaison roue-arbre, notamment d'une pompe de refroidissement d'un reacteur nucleaire, ladite pompe comprenant: - un conduit d'entree et un conduit de sortie pour le fluide pompe; - un arbre monte en rotation; - une roue montee sur ledit arbre, un ecrou de blocage axial etant visse sur l'arbre et dimensionne au moins de facon a supporter l'effort hydraulique axial de la roue; - une barriere thermique disposee au-dessus de la roue. Selon l'invention, un palier hydrostatique etant monte sur la ceinture exterieure de la roue, ladite liaison roue-arbre est realisee par au moins un dispositif de centrage et de fixation comportant une portee cylindrique et une butee axiale et par un dispositif de reprise du couple, independant dudit dispositif de centrage et de fixation
