Abstract

The approach which is proposed here relates to an adjusting sleeve (105) for a bearing device (100) having at least one housing (110) for receiving a bearing sleeve (115), the bearing sleeve (115) for receiving a shaft (120), and the shaft (120). The adjusting sleeve (105) is configured to be capable of being received between the bearing sleeve (115) and the housing (110) and to be thermally conductive. To this end, an outer wall (125) of the adjusting sleeve (105) has at least one outer depression (135) which is configured to produce an outer chamber (140) between the adjusting sleeve (105) and the housing (110) in a received state of the adjusting sleeve (105) in the bearing device (100), and/or an inner wall (130) of the adjusting sleeve (105) has at least one inner depression (145) which is configured to produce an inner chamber (150) between the adjusting sleeve (105) and the bearing sleeve (115) in the received state of the adjusting sleeve (105) in the bearing device (100).

4. The adjusting sleeve ( 105 ) as claimed in claim 1 , wherein the adjusting sleeve ( 105 ) is shaped to be pressed into the housing ( 110 ) in order to produce a frictional and/or nonpositive joint between the adjusting sleeve ( 105 ) and the housing ( 110 ), and/or to be pressed onto the bearing sleeve ( 115 ) in order to produce a frictional and/or nonpositive joint between the adjusting sleeve ( 105 ) and the bearing sleeve ( 115 ).

5. The adjusting sleeve ( 105 ) as claimed in claim 1 , wherein the at least one outer depression ( 135 ) and the at least one inner depression ( 145 ) extend along the central axis of the adjusting sleeve ( 105 ) to radially overlap.

6. The adjusting sleeve ( 105 ) as claimed in claim 1 , wherein the at least one outer depression ( 135 ) and the at least one inner depression ( 145 ) are substantially uniform in cross-sectional shape.

7. The adjusting sleeve ( 105 ) as claimed in claim 1 , wherein the adjusting sleeve ( 105 ) has a substantially constant radial thickness along the central axis of the adjusting sleeve ( 105 ).

8. The adjusting sleeve ( 105 ) as claimed in claim 1 , wherein a cross-section of the adjusting sleeve ( 105 ) has a wave-like configuration.
