Abstract
Abstract The inner racering of a ball bearing assembly includes a portion which extends beyond the face of the bearing axially about a shaft extending through the racering bore. Two holes are drilled in the inner race extension and are spaced apart about the shaft by an angle measured in a radial direction from the shaft axes which subtends an arc of substantially between 30* to 60*. Set screws are threaded through the apertures and meet the shaft in an interference fit thereby locking the inner racering to the shaft.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
139 words
In a bearing assembly having an inner member and an outer member which are relatively rotatable and which are spaced apart for receiving anti-friction elements and lubricant therebetween and having apparatus for connecting one of the inner and outer members to a rotating shaft which apparatus includes threadable locking means threaded to make an interference fit with the rotating shaft, the improvement characterized by the threadable locking means including first and second threadable members, said first and second threadable members positioned about the shaft in a spaced apart angular relationship and contacting the shaft in an interference fit to lock the selected one of the inner and outer members to the shaft, said threadable members being spaced apart on said shaft by an angle of substantially between 30* and 60* measured in a radial direction from the shaft axis.
Claim 2
Dependent Claim
139 words
In a bearing assembly having an inner member and an outer member which are relatively rotatable and which are spaced apart for receiving anti-friction elements and lubricant therebetween and having apparatus for connecting one of the inner and outer members to a rotating shaft which apparatus includes threadable locking means threaded to make an interference fit with the rotating shaft, the improvement characterized by the threadable locking means including first and second threadable members, said first and second threadable members positioned about the shaft in a spaced apart angular relationship and contacting the shaft in an interference fit to lock the selected one of the inner and outer members to the shaft, said threadable members being spaced apart on said shaft by an angle of substantially between 30* and 60* measured in a radial direction from the shaft axis.
Claim 3
Dependent Claim
13 words
The bearing assembly of claim 1 wherein said threadable members are set screws.
Claim 4
Dependent Claim
53 words
The bearing assembly of claim 2 wherein the shaft extends through a bore in the inner member which inner member further includes a portion extending axially about the shaft, and wherein the set screws are threaded through the axially extending portion of the inner member thereby engaging the shaft in an interference fit.
Claim 5
Dependent Claim
142 words
In a ball bearing assembly having an outer racering and an inner racering which are relatively rotatable and which are spaced apart for receiving balls and lubricant therebetween, the assembly further including the inner racering having a portion extending beyond the face of the bearing about a shaft positioned in a bore in the inner racering which extension includes a plurality of apertures for receiving locking members therein to lock the inner racering to the shaft, the improvement being characterized by said extension of the inner racering having two apertures spaced apart about the shaft by an angle measured in a radial direction from the shaft axis which subtends an arc of substantially between 30 * to 60* , and set screws threaded through said apertures and meeting said shaft in an interference fit thereby locking the inner racering to the shaft.
Claim 6
Dependent Claim
142 words
In a ball bearing assembly having an outer racering and an inner racering which are relatively rotatable and which are spaced apart for receiving balls and lubricant therebetween, the assembly further including the inner racering having a portion extending beyond the face of the bearing about a shaft positioned in a bore in the inner racering which extension includes a plurality of apertures for receiving locking members therein to lock the inner racering to the shaft, the improvement being characterized by said extension of the inner racering having two apertures spaced apart about the shaft by an angle measured in a radial direction from the shaft axis which subtends an arc of substantially between 30 * to 60* , and set screws threaded through said apertures and meeting said shaft in an interference fit thereby locking the inner racering to the shaft.
Claim 7
Dependent Claim
15 words
The ball bearing assembly of claim 4 wherein said angle subtends an arc of 45*.
Claim 8
Dependent Claim
24 words
The ball bearing assembly of claim 4 further including seal means for preventing contaminants from entering the space between the inner and outer racering.
