An apparatus is described for thermomechanical decoupling of the housing (1, 2) and stationary part (5, 6, 7) of a rotating machine, in particular of a dynamoelectric machine. The apparatus is characterized in that it has at least one rotating shell (4), and in that this apparatus can on the one hand be attached to the housing (1, 2) and on the other hand to the stationary part (5, 6, 7), such that the rotating shell extends in the axial direction even in the mounted state. This results in centred bearing, which is stiff against lateral movement of the stationary part, in particular of the laminated core, while providing little impediment in particular to the thermal growth of the stationary part.
L'invention concerne un dispositif de découplage thermomécanique du boîtier (1, 2) et de la partie (5, 6, 7) fixe d'une machine en rotation, notamment pour une machine dynamoélectrique. Le dispositif est caractérisé en ce qu'il présente au moins une coque (4) rotative et en ce qu'il peut être fixé d'un côté au boîtier (1, 2) et de l'autre côté à la partie (5, 6, 7) fixe de sorte que la coque rotative s'étende également dans le sens axial à l'étant fixé. On obtient ainsi un soutien rigide centré empêchant le décalage latéral de la partie fixe, notamment de l'empilage de tôles, tout en gênant peu la croissance thermique de la partie fixe en particulier.
