Title
(EN) STABILIZING BUSHING CONSTRUCTED OF FIBER REINFORCED STRUCTURAL COMPOSITE
(FR) DOUILLE DE STABILISATION CONSTITUÉE D'UN COMPOSITE STRUCTUREL RENFORCÉ PAR DES FIBRES
Abstract
(EN)
A stabilizing bushing is constructed of a structural composite including layers of reinforcing fibers in a matrix of synthetic polymeric material, and is inserted between a rotating shaft and a surrounding housing to stabilize the shaft against unwanted radial displacement while rotating within the housing. A plurality of circumferential grooves in the bushing effect a reduction in fluid pressure between one end of the bushing exposed to higher fluid pressures than to which the opposite end of the bushing is exposed. The bushing is constructed in the form of circumferential segments selectively joined together at Z-shaped joints for facilitating the insertion and establishment of a securely integrated stabilizing bushing in position around the shaft.
(FR)
Une douille de stabilisation est constituée d'un composite structurel comprenant des couches de fibres de renforcement dans une matrice de matériau polymère synthétique, et est insérée entre un arbre rotatif et un boîtier environnant pour stabiliser l'arbre contre un déplacement radial indésirable tout en tournant à l'intérieur du boîtier. Une pluralité de rainures circonférentielles dans la douille permettent une réduction de la pression de fluide entre une extrémité de la douille exposée à des pressions de fluide supérieures à celles auxquelles l'extrémité opposée de la douille est exposée. La douille est construite sous la forme de segments circonférentiels assemblés de manière sélective ensemble au niveau de raccords en forme de Z pour faciliter l'insertion et l'établissement d'une douille de stabilisation intégrée de manière sûre en position autour de l'arbre.
