SPINDLE NUT ASSEMBLY
First Claim
Patent Images
1. A spindle nut assembly comprising:
- an inner nut adapted to be tightly threaded onto a spindle, the inner nut having a first bevel surface and being located at a desired bearing endplay setting; and
an outer nut having a second bevel surface that abuts against the first bevel surface to jam the inner and outer nuts together and tighten the inner nut to the spindle while maintaining the desired bearing endplay setting.

Abstract
A spindle nut assembly includes inner and outer nuts having corresponding beveled surfaces. The inner nut is tightly threaded onto an end of a spindle and is positioned to achieve a desired endplay setting. The outer nut contacts the inner nut at an oblique angle via the beveled surfaces, which squeezes the inner nut more tightly onto the spindle while still maintaining the desired endplay setting.

12. A wheel end assembly comprising:
-
a spindle; inboard and outboard wheel bearings mounted on the spindle; a hub supported on the inboard and outboard wheel bearings for rotation relative to the spindle; an inner washer abutting against the outboard wheel bearing; a bend tab washer positioned outboard of the inner washer; an inner nut positioned outboard of the bend tab washer and threaded tightly onto the spindle to achieve a desired bearing endplay setting, wherein the inner nut includes a first bevel surface; and an outer nut positioned outboard of the inner nut and having a second bevel surface that abuts against the first bevel surface to jam the inner and outer nuts together and further tighten the inner nut to the spindle while maintaining the desired bearing endplay setting. - View Dependent Claims (13, 14, 15, 16)

17. A method of assembling a spindle nut assembly comprising the steps of:
-
(a) supporting a hub on at least one bearing for rotation relative to a spindle; (b) installing an inner washer on one end of the spindle to abut against the at least one bearing; (c) installing a bend tab washer on the end of the spindle to abut against the inner washer; (d) threading an inner nut onto mating threads on the end of the spindle and tightening to a torque level sufficient to seat the at least one bearing, the inner nut having a first bevel surface; (e) backing the inner nut off to achieve a desired bearing endplay setting; and (f) installing an outer nut onto the inner nut, the outer nut having a second bevel surface in abutting engagement with the first bevel surface, and tightening the outer nut against the inner nut to securely hold the inner nut in place while still maintaining the desired bearing endplay setting. - View Dependent Claims (18, 19, 20, 21)
