Bearing module
A bearing module including a first bearing component and a second bearing component which are mounted such that the first bearing component and the second bearing component can move relative to one another, the first bearing component being an outer ring extending in a circumferential direction and the second bearing copmonent being a corresponding inner ring, a raceway is provided on one of the outer bearing and the inner bearing ring, and corrosion protection is provided at a side of the raceway, the corrosion protection being anodic corrosion protection and including one of a sacrificial anode or an impressed current anode. A separate protection means is provided, which is comprised of an oligodynamically acting material.
1. A bearing module, comprising:
a first bearing component and a second bearing component which are mounted such that the first bearing component and the second bearing component can move relative to one another, the first bearing component being an outer ring extending in a circumferential direction and the second bearing component being a corresponding inner ring;
a raceway is provided on one of the outer bearing ring and the inner bearing ring, and corrosion protection is provided at a side of the raceway, the corrosion protection being anodic corrosion protection and including one of a sacrificial anode or an impressed current anode; and
wherein a separate protection means is provided, which is comprised of an oligodynamically acting material.
2. The hearing module as claimed in claim 1 , wherein the anodic corrosion protection is provided adjacent the raceway, and in that a passive corrosion coating is provided at a greater distance from the raceway.
3. The bearing module as claimed in claim 1 , wherein the separate protection means is annular.
4. The bearing module as claimed in claim 1 , wherein the separate protection means consists of the material.
5. The bearing module as claimed in claim 1 , wherein the first bearing component and the second bearing component are mounted such that the first bearing component and the second bearing component can move relative to one another by means of a plurality of roller bodies.
6. The bearing module as claimed in claim 5 , wherein a cage is provided, in which the roller bodies are accommodated.
7. The bearing module as claimed in claim 6 , wherein the separate protection means is attached to the cage.
8. The bearing module as claimed in claim 6 , wherein the protection means is attached to the or each bearing component.
9. The bearing module as claimed in claim 8 , wherein the protection means has an attachment means for attachment.
10. The bearing module as claimed in claim 9 , wherein the attachment means is a screw means.
11. The bearing module as claimed in claim 8 , wherein a separating means is arranged between the protection means and the or each bearing component and/or the cage.
12. The bearing module as claimed in claim 6 , wherein the separate protection means is arranged on a surface of a body of the cage.
13. The bearing module as claimed in claim 12 , wherein the protection means is in the form of a coating on the surface of the cage.
14. The bearing module as claimed in claim 13 , wherein the protection means is a metallic coating and in that the roller bodies are formed from an electrically non-conductive material.
15. The bearing module as claimed in claim 14 , wherein the metallic coating is copper.
16. The bearing module as claimed in claim 1 , wherein the corrosion protection comprises a passive corrosion coating comprising a polymer lacquer.
