Embodiment Construction

[0021] In the following description of the drawings showing the embodiments, the same reference numerals denote the same or similar components. Furthermore, generalized reference numbers are used for components and objects that appear more than once in one embodiment or figure but are generally described in terms of one or more features. Components or objects described with the same or general reference signs can be designed identically with regard to individual, multiple or all features (for example their dimension design), but can also be designed differently if necessary, as long as they are specified by the description No other content is expressed or implied.

[0022] figure 1 A schematic cross section through a rolling bearing 1 according to an exemplary embodiment is shown. The section referred to here runs parallel to the axis of rotation and also runs through it. The rolling bearing 1 has an outer ring 2 and an inner ring 3 . A plurality of rolling elements are ar...

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) ...
