Abstract

A seal washer and a locknut assembly for retaining for instance a wheel on a shaft, the locknut assembly seal washer. The seal washer includes a cylindrical segment connected to and extending from an outer peripheral edge of the washer section, the cylindrical segment. The seal washer includes an outer seal contact surface. The locknut assembly also includes a nut having an annular portion, an anti-rotation member cooperative with the shaft and the nut, the anti-rotation member adapted to prevent rotation of the nut with respect to the shaft. The locknut assembly also includes a seal washer including a washer section and a cylindrical segment connected to and extending from an outer peripheral edge of the washer section, the cylindrical segment including an outer seal contact surface.

Claims

1. A seal washer comprising a washer section and a cylindrical segment connected to and extending from an outer peripheral edge of the washer section, the cylindrical segment including an inner seal contact surface.

2. The seal washer of claim 1 wherein the cylindrical segment further comprises a cylindrical segment extending substantially perpendicular to the outer peripheral edge of the washer section.

3. The seal washer of claim 1 wherein the cylindrical segment further comprises a substantially cylindrical segment.

4. A locknut assembly for retaining a rotation member on a shaft, the rotation member including a seal positioned in a mounting aperture located in the rotation member, the locknut assembly comprising:

a nut having an annular portion;

an anti-rotation member cooperative with the shaft and the nut, the anti-rotation member adapted to prevent rotation of the nut with respect to the shaft; and

a seal washer positioned on the shaft below the nut, the seal washer including a washer section and a cylindrical segment connected to and extending from an outer peripheral edge of the washer section, the cylindrical segment including an inner seal contact surface.

5. The seal washer of claim 4, wherein the cylindrical segment further comprises a cylindrical segment extending substantially perpendicular to the outer peripheral edge of the washer section.

6. The locknut assembly of claim 4 wherein the seal washer cylindrical segment further comprises a substantially cylindrical segment.

8. The seal washer of claim 5, wherein the cylindrical segment further comprises a substantially cylindrical segment.

7. A hub assembly comprising:

a shaft including a longitudinally extending channel;

a rotation member mounted on the shaft, the rotation member including a seal positioned in a mounting aperture located in the rotation member;

a nut having an annular portion;

a nut anti-rotation member cooperative with the shaft and the nut, the nut anti-rotation member adapted to prevent rotation of the nut with respect to the shaft; and

a seal washer including a washer section and a cylindrical segment connected to and extending from an outer peripheral edge of the washer section, the cylindrical segment including an inner seal contact surface.
