Abstract
Abstract A bearing in which a locking or locating pin is used to substantially prevent relative motion between its outer race and its housing, the locking pin preferably being formed by a cold heading technique from a slug of metal so, as to have a generally cylindrical sleeve and a pin-like member in the sleeve which extends therefrom. When an axial compressive force is applied to the locking pin, the pin-like member telescopes into the sleeve, thereby preventing damage to the outer race of the bearing.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
149 words
A bearing comprising a housing; an inner race and an outer race spaced from the inner race; anti-friction elements in the space between the races; the inner and outer races and the anti-friction elements being received in the housing; a lubrication passage through the housing; a dimple in the outer race having a bottom wall and being aligned with the lubrication passage; a small diameter passageway through the outer race joining the dimple and the space between the races; a locking pin in the lubrication passage which extends into the dimple and seats on the bottom thereof, said locking pin having an outer sleeve and an inner telescoping member; and a grease fitting threadably received in the lubrication passage which when set can exert an axial compressive force on the locking pin, whereby the locking pin telescopes to a lesser length when an axial compressive force is applied thereto.
Claim 2
Dependent Claim
149 words
A bearing comprising a housing; an inner race and an outer race spaced from the inner race; anti-friction elements in the space between the races; the inner and outer races and the anti-friction elements being received in the housing; a lubrication passage through the housing; a dimple in the outer race having a bottom wall and being aligned with the lubrication passage; a small diameter passageway through the outer race joining the dimple and the space between the races; a locking pin in the lubrication passage which extends into the dimple and seats on the bottom thereof, said locking pin having an outer sleeve and an inner telescoping member; and a grease fitting threadably received in the lubrication passage which when set can exert an axial compressive force on the locking pin, whereby the locking pin telescopes to a lesser length when an axial compressive force is applied thereto.
Claim 3
Dependent Claim
86 words
In a bearing having a pair of spaced races with anti-friction means therebetween, said races and anti-friction means being supported in a housing, means to permit the passage of lubrication to said anti-friction means, and means to substantially prevent relative rotation between said outer race and said housing comprising a locking pin, said locking pin comprising a generally cylindrical outer sleeve and a pin-like member snugly fitting in said sleeve, said pin-like member telescoping into said sleeve upon the application of an axial compressive force thereto.
Claim 4
Dependent Claim
86 words
In a bearing having a pair of spaced races with anti-friction means therebetween, said races and anti-friction means being supported in a housing, means to permit the passage of lubrication to said anti-friction means, and means to substantially prevent relative rotation between said outer race and said housing comprising a locking pin, said locking pin comprising a generally cylindrical outer sleeve and a pin-like member snugly fitting in said sleeve, said pin-like member telescoping into said sleeve upon the application of an axial compressive force thereto.
Claim 5
Dependent Claim
85 words
A locking pin for use only in an anti-friction bearing having an outer race and a housing with a radial opening through a portion thereof and adapted to control relative rotation between said outer race and said housing, said locking pin being received in said opening and extending toward said outer race, said locking pin comprising a sleeve and a pin-like member received in said sleeve, said pin-like member being adapted to telescope into said sleeve upon the application of an axial compressive force thereon.
Claim 6
Dependent Claim
85 words
A locking pin for use only in an anti-friction bearing having an outer race and a housing with a radial opening through a portion thereof and adapted to control relative rotation between said outer race and said housing, said locking pin being received in said opening and extending toward said outer race, said locking pin comprising a sleeve and a pin-like member received in said sleeve, said pin-like member being adapted to telescope into said sleeve upon the application of an axial compressive force thereon.
Claim 7
Dependent Claim
39 words
A locking pin as recited in claim 3, wherein said housing opening is larger in diameter than said sleeve and said outer race has a dimple therein, and wherein a portion of said locking pin extends into said dimple.
