Bearing assembly

1. A bearing assembly comprising: at least one first bearing as an axially free radial support, at least one second bearing as a radially free axial support; the first bearing and second having a common axis of rotation, at least a first bearing ring of the first bearing and a second bearing ring of the second bearing being rotationally fixed in relation to at least one bearing seat, wherein the first bearing ring and the second bearing ring lie axially opposite each other and the second bearing ring is coupled with the first bearing ring, contactlessly in relation to the bearing seat, in a locking and rotationally fixed manner by means of at least one connecting element engaging in a locking manner in at least one corresponding clearance on the first bearing ring or the second bearing ring, the connecting element is formed separately from the first bearing ring and from the second bearing ring, and engages at least axially in one clearance respectively on the first bearing ring and on the second bearing ring.

2. The bearing assembly as claimed in claim 1 , wherein the connecting element is a Woodruff key, the Woodruff key engaging radially and axially in the clearances.

3. The bearing assembly as claimed in claim 1 , wherein the bearing seat is a housing, the first bearing ring being fixed on the housing.

4. The bearing assembly as claimed in claim 3 , wherein the bearing seat is a bore in the housing, the first bearing ring being accommodated in the bore in a rotationally fixed manner in relation to the housing.

5. The bearing assembly as claimed in claim 3 , wherein the first bearing ring and the second bearing ring are at least partially engaged around by the housing, the first bearing ring being fixed seated in a bore and that the second bearing ring is surrounded circumferentially on the outside by a radial air gap between the housing and the second bearing ring.

6. The bearing assembly as claimed in claim 5 , wherein the first bearing ring and the second bearing ring axially enter the bore at least partially and the bore is thereby described at least around the first bearing ring and around the second bearing ring by an inside diameter that is the same throughout.

7. The bearing assembly as claimed in claim 5 , wherein the first bearing ring and the second bearing ring axially enter the bore at least partially and the bore is thereby axially divided at least into a first portion and a second portion, the portions having inside diameters that are different from each other and the first portion running at least partially around the first bearing ring and the second bearing ring thereby arranged outside the first portion and radially separated from the second portion by the air gap.

8. The bearing assembly as claimed in claim 1 , wherein the first bearing and the second bearing are rolling bearings with rolling bodies.
