CA 2401274

An improved flexible support (10) for a steady bearing in rotational contact with the surface of a shaft allows the bearing and houseing to substantially track the contact surface of an impeller shaft when the shaft is subject to elastic deflection during operation. The flexible support employs a flexible disk pack (14), which is comprised of a plurality of thin, flexible disc elements in a stacked arrangement. The disk pack (14) is mounted to a support ring (16) and is also mounted to the bearing housing such that the bearing housing and other bearing elements are capable of deflection to substantially align with the axis of the impeller shaft when the shaft deflects.

L'invention concerne un support flexible amélioré (10) pour roulement fixe en contact rotatoire avec la surface d'un arbre permettant au roulement et au logement de retrouver sensiblement la surface de contact d'un arbre d'entraînement lorsque l'arbre est soumis à une déflexion élastique au cours de son utilisation. Le support flexible comprend un ensemble (14) de disques flexibles formé de plusieurs éléments de disques flexibles empilés. L'ensemble (14) de disques est monté sur un anneau (16) de support et est également monté dans le logement du roulement de manière que le logement du roulement et les autres éléments du roulement puissent défléchir pour s'aligner sensiblement avec l'axe de l'arbre d'entraînement lorsque l'arbre défléchit.
