Title
(EN) BEARING SUPPORT ASSEMBLY AND MACHINING METHOD THEREFOR, AND CENTRIFUGAL COMPRESSOR
(FR) ENSEMBLE FORMANT CHAISE DE PALIER ET SON PROCÉDÉ D'USINAGE, ET COMPRESSEUR CENTRIFUGE

Abstract
(EN)
A bearing support assembly and a machining method therefor. The bearing support assembly comprises: a bearing bracket (52) provided with a through-hole (522) for mounting a radial bearing (8); and a fixing plate (51) detachably mounted at one end of the bearing bracket (52) in an axial direction, the side of the fixing plate (51) away from the bearing bracket (52) being used for mounting a first thrust bearing (10’). The fixing plate (51) and the bearing bracket (52) are of a split structure, facilitating ensuring the perpendicularity of the through-hole for mounting the radial bearing (8) to an end face for mounting the fixing plate (51) during machining, improving the assembly precision of the bearing and the stability of a bearing-rotor system, further improving the qualification rate of machined parts and reducing the machining cost. Also disclosed is a centrifugal compressor comprising a bearing support assembly.
(FR)
L'invention concerne un ensemble formant chaise de palier et son procédé d'usinage. L'ensemble formant chaise de palier comprend : un support de palier (52) pourvu d'un trou traversant (522) servant à des fins de montage d'un palier radial (8) ; et une plaque de fixation (51) montée de manière amovible au niveau d'une extrémité du support de palier (52) dans une direction axiale, le côté de la plaque de fixation (51) à l'opposé du support de palier (52) étant utilisé pour monter un premier palier de butée (10'). La plaque de fixation (51) et le support de palier (52) sont d'une structure fendue, ceci permettant de garantir la perpendicularité du trou traversant servant à des fins de montage du palier radial (8) au niveau d'une face d'extrémité pour monter la plaque de fixation (51) pendant l'usinage, d'améliorer la précision d'assemblage du palier et la stabilité d'un système de paliers-rotor, d'améliorer encore le taux de qualification de pièces usinées et de réduire le coût d'usinage. L'invention concerne également un compresseur centrifuge comprenant un ensemble formant chaise de palier.
