Abstract

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

Claims

1-9. (canceled)

10. A bearing ring comprising: at least one interior channel integrated proximate to a raceway, the at least one channel having a cross-sectional shape deviating from a circular shape.

11. The bearing ring as recited in claim 10 where the cross-sectional shape the at least one channel changes along a course of the channel.

12. A method for manufacturing a bearing ring, comprising the following steps: providing a powder of a low-carbon-containing steel; and forming a bearing ring including interior channels proximate to a raceway of the bearing ring with the aid of a generative manufacturing method.

13. The method as recited in claim 12 wherein laser melting is applied as the generative manufacturing method.

14. The method as recited in claim 12 wherein laser sintering is applied as the generative manufacturing method.

15. The method as recited in claim 12 further comprising a subsequent surface hardening of the bearing ring.

16. The method as recited in claim 15 wherein the surface hardening includes an enrichment with carbon.

17. A method for manufacturing the bearing ring as recited in claim 10 wherein the formation of the bearing ring includes a formation of the at least one channel, the at least one channel including a plurality of channels having a cross-sectional shape deviating from a circular shape.

18. The method for manufacturing the bearing ring as recited in claim 10 wherein the formation of the bearing ring includes a formation of the at least one channel, the at least one channel including a plurality of channels having a cross-sectional shape changing along a course of the channels.
