Abstract
An apparatus is described for thermomechanical decoupling of the housing and stationary part of a rotating machine, in particular of a dynamoelectric machine. The apparatus has at least one rotating shell, and in that this apparatus can on the one hand be attached to the housing and on the other hand to the stationary part, such that the rotating shell extends in the axial direction even in the mounted state. This results in centered bearing, which is stiff against lateral movement of the stationary part, in particular of the laminated core, while providing little impediment to the thermal growth of the stationary part.
