Bearing arrangement for turbo-machines

摘要

A bearing arrangement for turbo-machines containing a bearing housing, a rotor mounted on a rotor shaft in an overhung position, and a roller bearing set. The roller bearing set contains at least two roller bearings arranged on a one-part cylindrical bearing carrier with a minimum installed clearance. The bearing carrier is inserted into a bearing bore of the bearing housing leaving a radial installed gap that permits dampened movements of vibration. The carrier is supported on the peripheral side of the bore with initially tensioned, elastic vibration damping elements.
