Plastic sleeve on support bearing
A sleeve is provided on a seal seat of a bearing ring, for example an outer bearing ring of a propshaft bearing. The sleeve receives a bearing seal in an interference fit.
1. An outer ring assembly for a bearing of a vehicle propshaft, comprising:
an outer ring, including:
a race for receiving a rolling element,
a contact surface for engaging a seal,
an axially outer face, and
a radially outer surface; and
a corrosion-resistant sleeve covering at least the contact surface for receiving a seal with an interference fit, the corrosion-resistant sleeve having a first sleeve part and a second sleeve part separated by a gap.
2. The outer ring assembly of claim 1 , wherein the first sleeve part covers a first axial end of the outer ring and the second sleeve part covers a second axial end of the outer ring.
3. The outer ring assembly of claim 1 , wherein the radially outer surface has a notch, and the corrosion-resistant sleeve has a tab for mounting in the notch.
4. The outer ring assembly of claim 1 , wherein the corrosion-resistant sleeve includes a base covering the outer surface, an extension covering the axially outer face, and an arm covering the contact surface.
5. The outer ring assembly of claim 1 , wherein the outer ring includes a second contact surface and a second axially outer face, and wherein the corrosion-resistant sleeve covers both the contact surface and the second contact surface.
6. The outer ring assembly of claim 5 , wherein the radially outer surface has a notch, and the corrosion-resistant sleeve has a tab for mounting in the notch.
7. The outer ring assembly of claim 6 , wherein the contact surface defines a groove.
8. The outer ring assembly of claim 7 , wherein the corrosion-resistant sleeve includes a flange mounted in the groove.
9. The outer ring assembly of claim 8 , wherein the flange is sized and shaped to substantially mate within the groove.
10. The outer ring assembly of claim 9 , wherein the corrosion-resistant sleeve is configured to snap onto the outer ring.
11. A rolling bearing assembly, comprising:
a first ring including a first race;
a second ring including a second race;
a plurality of rolling elements in rolling contact with the first and second races;
a sleeve mounted to the second ring, the sleeve being comprised of a first sleeve part and a second sleeve part separated by a gap; and
a seal including a rigid flinger in interference fit with the first ring and a compliant portion in interference fit with the sleeve.
12. The rolling bearing assembly of claim 11 , wherein the first sleeve part covers a first axial end of the outer ring and the second sleeve part covers a second axial end of the outer ring.
13. The rolling bearing assembly of claim 11 , wherein the sleeve is plastic.
14. The outer ring assembly of claim 11 , wherein a radially outer surface of the second ring has a notch, and the sleeve has a tab for mounting in the notch.
