Abstract

A rolling bearing assembly, comprising at least a rolling bearing outer ring ( 4 ) of a rolling bearing, an intermediate element that surrounds the rolling bearing outer ring ( 4 ), and a housing part, into which the intermediate element ( 9 ) is inserted. The outer ring ( 4 ) is rotatably arranged in the intermediate element ( 9 ) and has a circumferential oil catching strip ( 6 ) at one of the end faces thereof, which oil catching strip is designed to convey oil into a contact zone formed between the outer ring ( 4 ) and the intermediate ring ( 9 ). A damping system having a damping recess is formed between the housing and the intermediate element ( 9 ).

Claims (13)

1. A rolling bearing assembly comprising:

at least one outer ring of a rolling bearing;

an annular intermediate element;

a housing, the rolling bearing being insertable into the housing in such a way that the intermediate element is situated between the outer ring and the housing, a first contact zone being provided between the outer ring and the intermediate element, and a second contact zone being provided between the intermediate element and the housing;

a cooling system being provided in the first contact zone, the cooling system having at least one cooling recess through which a coolant may flow;

a damping system being provided in the second contact zone, the damping system having at least one oil transfer line, via which a groove in the second contact zone may be filled with a damping medium,

the outer ring being rotatably situated in the intermediate element; and

a circumferential oil retaining strip provided on a front side of the outer ring and designed to convey oil to the first contact zone, wherein

the cooling system in the first contact zone is fluidically connected to the damping system in the second contact zone.

2. The rolling bearing assembly as recited in claim 1 wherein the outer ring has an oil inlet bore on a front side opposite the oil retaining strip.

3. The rolling bearing assembly as recited in claim 1 wherein the intermediate element has the oil transfer line, the oil transfer line connecting the first contact zone to the second contact zone.

4. A gas turbine bearing comprising the roller bearing assembly as recited in claim 1 .

5. A helicopter comprising the roller bearing assembly as recited in claim 1 .
