MACHINE ARRANGEMENT

摘要

The invention relates to a machine arrangement (1) comprising a housing element (2) and a rotor element (3), wherein the rotor element (3) is rotatable supported in the housing element (2) by at least one bearing (4), wherein the at least one bearing (4) has an inner ring (5) and an outer ring (6), wherein the housing element (2) has a reception (7) for the bearing (4). To improve the rotor dynamic behavior of a high speed machine the invention proposes that a ring element (8) is arranged between the outer circumference (9) of the outer ring (6) and the reception (7) of the housing element (2) and/or between the inner circumference of the inner ring (5) and the rotor element (3), wherein at least one cavity (10) is arranged in the inner of the ring element (8), wherein the cavity (10) is filled with a pressurized fluid (1 1) and wherein the cavity (10) has a fluidic connection (14) to the environment.
