ABSTRACT:
A flexibly damped shaft bearing arrangement with a bearing housing that surrounds the shaft in a ring, and a movable bearing support, which contains the shaft bearing and is suspended radially by springs in the bearing housing, contains a fluid pressure cushion between the bearing housing and the bearing support for damping purposes. In order to be able to adapt this shaft bearing arrangement for electrical machines in various states or stages of operation, there is provided, according to the invention, between the bearing housing and the bearing support, an second stage elastic suspension, which, when the machine equipped with such bearings is not operating, has a clearance with respect to the bearing support, which is smaller than the potential spring excursion of the bearing support. The clearance and the rigidity of the second stage suspension are designed to be adjusted or exchanged.
