Abstract
Abstract A method for refurbishing used assembled anti-friction bearings in which the bearings are first given a preliminary washing with a solvent and the seals and shields on the bearing are removed. The bearing is then placed in a vibratory finishing mill having a quantity of finishing material therein which acts upon and finishes the bearing for a predetermined period of time. The finishing media is then washed from the bearing, the bearing is lubricated and new shields are replaced. The final finishing of new bearings may also be accomplished in accordance with the method disclosed herein.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
83 words
A method of finishing an anti-friction bearing having an inner race, an outer race, and a plurality of rolling elements spaced between said races comprising the steps of: a. placing said bearing together with an abrasive finishing media in a vibratory finishing mill; b. operating said mill to subject said bearing and said media to a vibratory action for a period of time sufficient to finish said bearing; c. removing said bearing from said media; and d. cleaning said media from said bearing.
Claim 2
Independent Claim
83 words
A method of finishing an anti-friction bearing having an inner race, an outer race, and a plurality of rolling elements spaced between said races comprising the steps of: a. placing said bearing together with an abrasive finishing media in a vibratory finishing mill; b. operating said mill to subject said bearing and said media to a vibratory action for a period of time sufficient to finish said bearing; c. removing said bearing from said media; and d. cleaning said media from said bearing.
Claim 3
Dependent Claim
32 words
The method of finishing a bearing as described in claim 1 wherein said vibratory action is a relatively high frequency tilting and rolling action having relatively high amplitude horizontal and vertical components.
Claim 4
Dependent Claim
24 words
The method of finishing a bearing as described in claim 2 and further including the steps of lubricating the bearing and testing the bearing.
Claim 5
Independent Claim
104 words
A method of finishing an anti-friction bearing having an inner race, an outer race, and a plurality of rolling elements spaced between said races comprising the steps of: a. assembling an infinished inner race and an unfinished outer race together with a plurality of rolling elements therebetween; b. placing said unfinished inner race, outer race and rolling elements together with an abrasive finishing media in a vibratory finishing mill; and c. operating said mill to subject said bearing in its assembled state to a vibratory action in the presence of said abrasive finishing media for a period of time sufficient to finish said bearing.
Claim 6
Independent Claim
104 words
A method of finishing an anti-friction bearing having an inner race, an outer race, and a plurality of rolling elements spaced between said races comprising the steps of: a. assembling an infinished inner race and an unfinished outer race together with a plurality of rolling elements therebetween; b. placing said unfinished inner race, outer race and rolling elements together with an abrasive finishing media in a vibratory finishing mill; and c. operating said mill to subject said bearing in its assembled state to a vibratory action in the presence of said abrasive finishing media for a period of time sufficient to finish said bearing.
Claim 7
Dependent Claim
32 words
The method of finishing a bearing as described in claim 4 wherein said vibratory action is a relatively high frequency tilting and rolling action having relatively high amplitude horizontal and vertical components.
Claim 8
Dependent Claim
32 words
The method of finishing bearings as describEd in claim 4 and further including the steps of removing said bearing from said mill and said media; and cleaning said media from said bearing.
Claim 9
Dependent Claim
23 words
The method of finishing bearings as described in claim 6 and further comprising the steps of lubricating said bearing and testing said bearing.
Claim 10
Dependent Claim
40 words
A method of finishing bearings as described in claim 4 and further including the steps of: a. removing said finished bearing from said vibratory finishing mill; b. removing said abrasive finishing material from said bearing; and c. lubricating said bearing.
Claim 11
Independent Claim
66 words
A method of refurbishing used anti-friction bearings comprising the steps of: a. washing said bearing in a solvent; b. placing said washed bearing in an abrasive finishing material in a vibratory finishing mill; c. operating said mill for a period of time sufficient to clean said bearing; d. removing said bearing from said mill; e. cleaning said media from said bearing; and f. lubricating said bearing.
Claim 12
Independent Claim
66 words
A method of refurbishing used anti-friction bearings comprising the steps of: a. washing said bearing in a solvent; b. placing said washed bearing in an abrasive finishing material in a vibratory finishing mill; c. operating said mill for a period of time sufficient to clean said bearing; d. removing said bearing from said mill; e. cleaning said media from said bearing; and f. lubricating said bearing.
Claim 13
Dependent Claim
33 words
The method of refurbishing an anti-friction bearing as described in claim 9 wherein said vibratory action is a relatively high frequency tilting and rolling action having relatively high amplitude horizontal and vertical components.
