A bearing assembly () is provided, in particular for a turbomachine, including: an inner bearing race (); an outer bearing race () having at least one cooling channel () formed within it or in its outer surface; rolling elements () made of ceramic and disposed between the inner bearing race () and the outer bearing race (); and a surrounding bearing ring () connected to the outer bearing race () and configured to form a squeeze film () of oil between its outer surface and an opposite inner surface of a housing () in which the bearing assembly can be mounted.

Bearing assembly, in particular for a turbomachine, and turbomachine having such a bearing assembly

A bearing ring with integrated cooling channels and a method for producing a bearing ring with integrated cooling channels are provided.

Bearing ring and layer by layer method for manufacturing a bearing ring

A rolling bearing assembly, comprising at least a rolling bearing outer ring () of a rolling bearing, an intermediate element that surrounds the rolling bearing outer ring (), and a housing part, into which the intermediate element () is inserted. The outer ring () is rotatably arranged in the intermediate element () and has a circumferential oil catching strip () 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 () and the intermediate ring (). A damping system having a damping recess is formed between the housing and the intermediate element ().

Rolling bearing assembly

A rolling bearing arrangement which has at least one rolling bearing outer ring of a rolling bearing, an intermediate element, and a housing part. 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 that has at least one cooling recess through which a cooling agent can flow. Formed on the second contact zone is a damping system that has at least one damping recess via which a damping cavity in the second contact zone can be filled with a damping medium.
