Problems solved by technology

[0004] At the same time, in the described application of high-performance rolling bearings, axial and radial vibrations also occur, which can have a disturbing effect on the operation of the rolling bearings
Due to such a situation, damage to the rolling bearing, up to destruction of the rolling bearing, can occur, mainly through a relative rotation of the rolling bearing towards the housing caused by radial vibrations or the contact of the rolling bearing on a housing part

Embodiment Construction

[0051] Depend on figure 1 The rolling bearing system or (below) the bearing system 12 with a combined cooling and damping system is shown in axial cross-section. The bearing system 12 is provided in particular within the scope of the transmission bearing.

[0052] According to the drawing, the bearing system 12 includes a bearing module 13 consisting of a rolling bearing (shown with rolling bodies 2 and a rolling bearing outer ring 1 ) and a ring 6 , as well as a housing part 9 . In this case, the bearing module 13 or the collar 6 is inserted into the cavity 14 of the housing part 6 . The bearing module 13 itself comprises, as shown, an outer rolling bearing ring 1 and rolling bodies 2 onto which rings 6 are pressed. The rolling bearing outer ring 1 is also configured with a spring rod 3 or a flange 3 with a flange bore 10 .

[0053] Such as figure 1 It can be seen that the collar 6 fits precisely into the cavity 14 along the outer contour 15 , except for a circumferential...

Abstract

The invention relates to a rolling bearing arrangement comprising at least one rolling bearing outer ring of a rolling bearing, an intermediate element, and a housing part, wherein the rolling bearing can be inserted into the housing part such that the intermediate element lies between the rolling bearing outer ring and the housing part. A first contact zone is formed between the rolling bearing outer ring and the intermediate element, and a second contact zone is formed between the intermediate element and the housing part. Formed on the first contact zone is a cooling system having at least one cooling recess through which a cooling agent can flow. Formed on the second contact zone is a damping system having at least one damping recess via which a damping cavity in the second contact zone can be filled with a damping medium.

Description

technical field [0001] The invention relates to the field of high-performance rolling bearings, in particular their use in high-speed rotating gas turbines, drive / gear bearings or spindle bearings of transmissions and, for example, propeller bearings in helicopters. Background technique [0002] In these applications of rolling bearings, operating temperatures well above 200° C. can easily arise due to the very high operating speeds under extremely high loads in the contact region between the rolling elements of these bearings and the bearing rings. The heat generated by frictional power at high speeds must be dissipated reliably and smoothly in order to avoid bearing damage. A rolling bearing cooling system is used for this. [0003] A cooling system for such applications is known from DE 10 2006 024 603 A1. On the outer shell surface of the outer ring of this rolling bearing, there are provided a plurality of recesses for the cooling medium of the cooling system to flow ...
