Abstract

A bearing system includes a bearing comprising a first end and a second end opposite to the first end. The bearing further comprises a plurality of threads adjacent to the second end. The plurality of threads comprise a first slot perpendicular to the plurality of threads. The bearing system also includes a washer comprising a first surface adjacent to the second end of the bearing and a plane parallel to the first surface. The washer further comprises a plurality of side tabs extending from a second surface in a direction parallel to the plane and a first tab extending from the first surface in a direction perpendicular to the plane. The first tab mates with the first slot of the bearing. The bearing system further comprises a nut positioned between the first end of the bearing and the first surface of the washer.

First claim

What is claimed is:

1. A bearing system, comprising:
a bearing comprising a first end and a second end opposite to the first end, the bearing comprising a plurality of threads adjacent to the second end, the plurality of threads comprising a first slot perpendicular to the plurality of threads, wherein the bearing comprises a ridge positioned between the first end and the second end, the ridge adjacent to the plurality of threads and comprising a second slot perpendicular to the first slot;
a washer comprising:
a first surface adjacent to the second end of the bearing and defining a plane parallel to the first surface;
a plurality of side tabs extending from a second surface in a direction parallel to the plane; and
a first tab, the first tab including a first portion extending from the first surface in a direction perpendicular to the plane, the first portion mating with the first slot of the bearing, the first tab including a second portion extending in a direction perpendicular to the first portion, the second portion mating with the second slot of the bearing; and

a nut positioned between the first end of the bearing and the first surface of the washer, wherein the nut comprises a plurality of grooves that each mate with one of the plurality of side tabs of the washer, wherein each of the plurality of side tabs of the washer are operable to bend into one of the plurality of grooves of the nut.

2. The bearing system of claim 1 , wherein the first slot extends through each of the plurality of threads.

3. The bearing system of claim 1 , wherein the first portion of the washer is positioned below each of the plurality of threads of the bearing.

4. The bearing system of claim 1 , wherein the washer comprises a metal.

5. A method of mounting a bearing system, comprising:
positioning a bearing in a lug of an object, the bearing comprising a first end and a second end opposite to the first end, the bearing comprising a plurality of threads adjacent to the second end, the plurality of threads comprising a first slot perpendicular to the plurality of threads, the bearing comprising a ridge positioned between the first end and the second end, the ridge adjacent to the plurality of threads and comprising a second slot perpendicular to the first slot, the second slot configured to mate with a tab of a washer;
positioning a nut on a first tab of the washer, the washer further comprising:
a first surface defining a plane parallel to the first surface and a second surface opposite to the first surface;
a plurality of side tabs extending from the second surface in a direction parallel to the plane, wherein the first tab extends from the first surface in a direction perpendicular to the plane; and
a second tab extending from the first tab in a direction perpendicular to the first tab, the second tab mating with the second slot of the bearing;

securing the nut to the plurality of threads of the bearing such that the nut is positioned between the first end of the bearing and the first surface of the washer, the first surface of the washer is positioned adjacent to the second end of the bearing, and the first tab of the washer mates with the first slot of the bearing;
aligning each of the plurality of side tabs of the washer with one of a plurality of grooves of the nut; and
bending each of the plurality of side tabs into one of the plurality of grooves.
