Abstract

A bearing housing cover for a bearing housing of a charging device is presented. The housing cover is formed of metal by a mechanisms of at least one of internal high-pressure forming (IHU), deep-drawing, forging and roller burnishing.

Claims (26)

1. A bearing housing cover for a bearing housing of a charging device comprising:

at least one elongated cylindrical fixing region for the radial fixing of at least one piston ring;

a disc-shaped covering region; and

an elongated cylindrical joining region;

wherein the joining region includes at least one radial groove configured to receive a sealing element.

2. The bearing housing cover according to claim 1 , wherein the bearing housing cover comprises at least two part regions, each produced of metal sheets and joined to each other.

3. The bearing housing cover according to claim 1 , wherein the bearing housing cover is simultaneously designed as a heat shield.

4. The bearing housing cover according to claim 1 , wherein the bearing housing cover is formed of at least one of aluminium, precision casting and sheet steel.

5. The bearing housing cover according to claim 1 , wherein said elongated cylindrical joining region is greater than or equal in length to said elongated cylindrical fixing region.

6. The bearing housing cover according to claim 5 , wherein said radial groove is positioned to substantially radially align with the radial fixing of at least one piston ring.

7. A bearing housing cover for a bearing housing of a charging device comprising:

at least one elongated cylindrical fixing region for the radial fixing of at least one piston ring;

a disc-shaped covering region; and

an elongated cylindrical joining region;

wherein the covering region includes a profiling which is a radially active clamping element; and

wherein the bearing housing cover is formed of metal by a mechanism of at least one of internal high-pressure forming (IHU), deep-drawing, forging and roller burnishing.

8. The bearing housing cover according to claim 7 , wherein the bearing housing cover is simultaneously designed as a heat shield and is formed of at least one of aluminium, precision casting and sheet steel.

9. A cover for a bearing housing of a charging device comprising:

the bearing housing cover comprising:

at least one elongated cylindrical fixing region for the radial fixing of at least one piston ring;

a disc-shaped covering region; and

an elongated cylindrical joining region;

wherein the joining region includes at least one radial groove configured to receive a sealing element wherein the bearing housing cover is unitarily produced of a metal sheet formed by a mechanism of at least one of internal high-pressure forming (IHU), deep-drawing, forging and roller burnishing.

10. The cover according to claim 9 , wherein the covering region includes a profiling which is a radially active clamping element.

11. The bearing housing cover according to claim 9 , wherein the bearing housing cover comprises at least two part regions, each produced of metal sheets and joined to each other.

12. The bearing housing cover according to claim 9 , wherein said radial groove is positioned to substantially radially align with the radial fixing of at least one piston ring.
