Title (EN) ROTATING MACHINE WITH AT LEAST ONE ACTIVE MAGNETIC BEARING AND SPACED AUXILIARY ROLLING BEARINGS
(FR) MACHINE ROTATIVE AYANT AU MOINS UN PALIER MAGNÉTIQUE ACTIF ET DES PALIERS À ROULEMENT AUXILIAIRES ESPACÉS
Abstract: front page image
(EN)The rotating machine comprises a shaft (14), a casing (12), at least one main magnetic bearing connected to the shaft for rotatably supporting said shaft inside the casing, at least one first and one second auxiliary rolling bearings (20, 22) positioned between the shaft and the casing to support axial and radial loads, and first and second axial abutment means (44, 54) positioned on the shaft to transmit axial loads to inner rings of the rolling bearings. The machine further comprises a spacer (28) axially positioned between facing faces of the inner rings (20a, 22a) of said rolling bearings for the transmission of the axial loads between said inner rings, and at least a first axial retaining means (58) positioned on the casing and located axially between facing faces of the outer rings (20b, 22b) for the transmission of the axial loads between at least one of said outer rings and the casing.
(FR)La présente invention se rapporte à une machine rotative qui comprend un arbre (14), un carter (12), au moins un palier magnétique principal raccordé à l'arbre pour supporter en rotation ledit arbre à l'intérieur du carter, au moins un premier et un second palier à roulement auxiliaire (20, 22) positionnés entre l'arbre et le carter pour supporter des charges axiales et radiales, ainsi qu'un premier et un second moyen de butée axial (44, 54) positionnés sur l'arbre pour transmettre des charges axiales à des bagues internes des paliers à roulement. La machine comprend en outre une pièce d'écartement (28) positionnée axialement entre les faces opposées des bagues internes (20a, 22a) desdits paliers à roulement pour permettre la transmission des charges axiales entre lesdites bagues internes, et au moins un premier moyen de retenue axial (58) positionné sur le carter et situé axialement entre les faces opposées des bagues externes (20b, 22b) pour permettre la transmission des charges axiales entre au moins l'une desdites bagues externes et le carter.
