Rolling bearing, high-speed bearing device and compressor

Abstract

An embodiment relates to a rolling bearing (1) having at least one outer ring (2) and at least one inner ring (3). A plurality of rolling bodies (4) is provided between the outer ring and the inner ring to support the inner ring (3) in a rotary mode with respect to the outer ring (2). The outer ring (2) has at least one more rollaway nest (5, 7) for the plurality of rolling bodies (4) than the inner race (3).

Description

technical field [0001] Embodiments of the invention relate to a rolling bearing, a high-speed bearing arrangement for rotatably supporting a first member relative to a second member, and a compressor. Background technique [0002] Completely different rolling bearings or rolling bearing arrangements can be used for the rotatable mounting of the component. First of all, high-speed applications place special demands on the bearing arrangement, for example due to the centrifugal forces that occur. Due to the rigidity of the bearing arrangement, a change in the position of the rotor or shaft occurs in the state of the applied load relative to the state of no external load. The bearing arrangement should avoid or at least limit a change or play in the axial position of the rotatably mounted component such as the rotor or the shaft. [0003] In traditional high-speed applications, a combination of ball bearings (angular contact ball bearings or four-point contact ball bearings) ...

Problems solved by technology

The material and / or labor costs in these bearing arrangements can be significantly increased by preloading and using several bearings
