Abstract
Abstract The present invention relates to an improved wheel bearing mounting of the type wherein one or more axially preloaded antifriction wheel bearings supporting a wheel hub are axially secured on a spindle by a spindle nut. The wheel bearing mounting of the present invention includes a spindle nut having a pair of aligned openings in opposite sides thereof for mating with a cotterway disposed in the threaded portion of the spindle. The spindle nut is of a size such that when the nut is threaded on the spindle to the position where the pair of aligned openings therein mate with the cotterway in the spindle, the desired axial preload on said bearings is provided.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
125 words
A wheel bearing mounting having an angular contact Antifriction wheel bearing secured on a spindle by a spindle nut, said spindle including a shoulder at one end for axially locating said bearing and a threaded portion at the opposite end for receiving said spindle nut, and having a cotterway in the threaded portion thereof located a predetermined distance from said shoulder, the improvement comprising: said spindle nut having a pair of aligned openings in opposite sides thereof for mating with said cotterway positioned equidistant from the ends thereof, and being of a size such that a predetermined required nonadjustable axial preload is provided on said bearing when said nut is positioned on said spindle with the pair of aligned openings therein mated with said cotterway.
Claim 2
Dependent Claim
125 words
A wheel bearing mounting having an angular contact Antifriction wheel bearing secured on a spindle by a spindle nut, said spindle including a shoulder at one end for axially locating said bearing and a threaded portion at the opposite end for receiving said spindle nut, and having a cotterway in the threaded portion thereof located a predetermined distance from said shoulder, the improvement comprising: said spindle nut having a pair of aligned openings in opposite sides thereof for mating with said cotterway positioned equidistant from the ends thereof, and being of a size such that a predetermined required nonadjustable axial preload is provided on said bearing when said nut is positioned on said spindle with the pair of aligned openings therein mated with said cotterway.
Claim 3
Dependent Claim
173 words
A wheel bearing mounting comprising: a spindle having a shoulder at one end and a threaded portion at the opposite end, and having a cotterway in said threaded portion positioned transversely to the axis of said spindle a predetermined distance from said shoulder; an antifriction axially preloaded wheel bearing having a pair of rotatable race rings slidably positioned on said spindle with one of said race rings adjacent to said shoulder; a spindle nut threaded on the threaded portion of said spindle adjacent to the other of said race rings having a pair of aligned openings in opposite sides thereof for mating with said cotterway, said spindle nut being of a size such that when positioned on the threaded portion of said spindle with the pair of aligned openings thereof mated with said cotterway, the desired nonadjustable axial preload on said bearing is provided; and a cotter pin extending through said pair of aligned openings in said spindle nut and through said cotterway in said spindle for locking said spindle nut in position.
Claim 4
Dependent Claim
173 words
A wheel bearing mounting comprising: a spindle having a shoulder at one end and a threaded portion at the opposite end, and having a cotterway in said threaded portion positioned transversely to the axis of said spindle a predetermined distance from said shoulder; an antifriction axially preloaded wheel bearing having a pair of rotatable race rings slidably positioned on said spindle with one of said race rings adjacent to said shoulder; a spindle nut threaded on the threaded portion of said spindle adjacent to the other of said race rings having a pair of aligned openings in opposite sides thereof for mating with said cotterway, said spindle nut being of a size such that when positioned on the threaded portion of said spindle with the pair of aligned openings thereof mated with said cotterway, the desired nonadjustable axial preload on said bearing is provided; and a cotter pin extending through said pair of aligned openings in said spindle nut and through said cotterway in said spindle for locking said spindle nut in position.
Claim 5
Dependent Claim
229 words
A wheel bearing mounting comprising: a spindle having a shoulder at one end and a threaded portion at the opposite end, and having a cotterway in said threaded portion positioned transversely to the axis of said spindle a predetermined distance from said shoulder; a pair of axially preloaded angular contact ball bearings, each of which is provided with an inner and outer race ring, slidably positioned on said spindle with the inner race ring of one of said bearings adjacent to said shoulder; a rotatable wheel hub positioned on the outer race rings of said bearings and supporting said outer race rings in a predetermined axially spaced relation; a nonrotatable thrust collar slidably mounted on said spindle adjacent to the inner race ring of the other of said bearings; a spindle nut threaded on the threaded portion of said spindle adjacent to said thrust collar, said spindle nut having a pair of aligned openings in opposite sides thereof for mating with said cotterway, and being of a size such that when threaded on the threaded portion of said spindle with the pair of aligned openings thereof mated with said cotterway, the desired nonadjustable axial preload is provided on said bearing; and a cotter pin extending through said pair of aligned openings in said spindle nut and through said cotterway in said spindle for locking said spindle nut in position.
Claim 6
Dependent Claim
229 words
A wheel bearing mounting comprising: a spindle having a shoulder at one end and a threaded portion at the opposite end, and having a cotterway in said threaded portion positioned transversely to the axis of said spindle a predetermined distance from said shoulder; a pair of axially preloaded angular contact ball bearings, each of which is provided with an inner and outer race ring, slidably positioned on said spindle with the inner race ring of one of said bearings adjacent to said shoulder; a rotatable wheel hub positioned on the outer race rings of said bearings and supporting said outer race rings in a predetermined axially spaced relation; a nonrotatable thrust collar slidably mounted on said spindle adjacent to the inner race ring of the other of said bearings; a spindle nut threaded on the threaded portion of said spindle adjacent to said thrust collar, said spindle nut having a pair of aligned openings in opposite sides thereof for mating with said cotterway, and being of a size such that when threaded on the threaded portion of said spindle with the pair of aligned openings thereof mated with said cotterway, the desired nonadjustable axial preload is provided on said bearing; and a cotter pin extending through said pair of aligned openings in said spindle nut and through said cotterway in said spindle for locking said spindle nut in position.
