Axiallagerung für schnellaufende Rotoren

摘要

The aim of the invention is to provide an improved axial bearing for high-speed rotors which is extremely stiff in the axial direction and very soft as regards inclined positions. It also aims to save space in the axial direction in the area of the bearing. To this end the invention provides for the load induction element (13) to comprise a bearing race body (16) adjoining the bearing collar (12), a membrane (17) joined to the bearing flange (6) and a central ring (18) which connects the bearing race body (16) to the membrane (17). The load induction element (13) is configured such that it narrows from the bearing race body (16) towards the central ring (18). The membrane (17) is supported on one side on an incompressible medium (23) which fills a hollow space (20) which is situated on the side of the membrane (17) facing away from the bearing collar (12) and is defined between the membrane (17) and an element (19) delimiting said hollow space (20). The element (19) limiting the hollow space (20) is either supported by the bearing flange (6) or embodied by same.
