Abstract
Abstract In securing a bearing cup in a hole in the yoke of a Hooke''s type universal joint, another hole having a diameter slightly greater than the diameter of the bearing cup hole is drilled in the yoke concentric with the bearing cup hole and to a depth so that the bases of both holes are in a common plane. After inserting the bearing cup into its hole so that its end is spaced a short distance from the common plane of the bases of the holes, a tool having a diameter slightly greater than the diameter of the bearing cup hole is positioned within the other hole and is rotated while it exerts pressure against the surface of the yoke in the common plane of the bases of the holes for deforming the wall of the bearing cup hole inwardly between the common plane and the end of the bearing cup for securely fixing the bearing cup in place.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
212 words
A method of fixing a bearing cup in a yoke having a bearing cup hole in a Hooke''s-type universal joint comprising the steps of drilling a hole having a diameter slightly greater than the diameter of the bearing cup hole into the surface of the yoke opposite and concentric with the bearing cup hole and forming the hole for a sufficient depth so that the bAse of the bearing cup hole and of the drilled hole are in a common plane, inserting a bearing cup into the bearing cup hole so that it is spaced slightly from the common plane containing the bases of the bearing cup hole and the drilled hole, inserting a tool into the drilled hole in contact with the surface of the yoke in the common plane of the bases of the bearing cup hole and the drilled hole, rotating the tool and exerting pressure against the surface of the yoke which is in the plane of the base of the drilled hole for deforming the surface of the yoke within the bearing cup hole and between the base of the bearing cup hole and the adjacent end of the bearing cup inwardly over the end of the bearing cup for fixing the bearing cup to the yoke.
Claim 2
Independent Claim
212 words
A method of fixing a bearing cup in a yoke having a bearing cup hole in a Hooke''s-type universal joint comprising the steps of drilling a hole having a diameter slightly greater than the diameter of the bearing cup hole into the surface of the yoke opposite and concentric with the bearing cup hole and forming the hole for a sufficient depth so that the bAse of the bearing cup hole and of the drilled hole are in a common plane, inserting a bearing cup into the bearing cup hole so that it is spaced slightly from the common plane containing the bases of the bearing cup hole and the drilled hole, inserting a tool into the drilled hole in contact with the surface of the yoke in the common plane of the bases of the bearing cup hole and the drilled hole, rotating the tool and exerting pressure against the surface of the yoke which is in the plane of the base of the drilled hole for deforming the surface of the yoke within the bearing cup hole and between the base of the bearing cup hole and the adjacent end of the bearing cup inwardly over the end of the bearing cup for fixing the bearing cup to the yoke.
Claim 3
Dependent Claim
31 words
A method, as set forth in claim 1, characterized therein by forming the drilled hole with a diameter of about 1.5 mm greater than the diameter of the bearing cup hole.
Claim 4
Dependent Claim
36 words
A method, as set forth in claim 1, characterized therein by spacing the bearing cup within the bearing cup hole about 1 mm from the common plane of the drilled hole and the bearing cup hole.
Claim 5
Dependent Claim
28 words
A method, as set forth in claim 2, characterized therein by employing a tool having a diameter about 0.5 mm less than the diameter of the drilled hole.
Claim 6
Dependent Claim
24 words
A method, as set forth in claim 4, characterized therein by employing a tool formed of a heat-resistant cemented-carbide alloy of high thermal strength.
Claim 7
Dependent Claim
49 words
A method, as set forth in claim 1, characterized therein by rotating the tool at about 3,000 rpm and applying a pressure of 150 kg on the tool against the surface of the yoke in the common plane of the bases of the bearing cup hole and drilled hole.
Claim 8
Dependent Claim
100 words
A method, as set forth in claim 1, characterized therein by providing the bearing cup hole with a diameter of 20 mm and drilling the drilled hole with a diameter of 21.5 mm, spacing the bearing cup 1 mm from the common plane of the bases of the bearing cup hole and the drilled hole, using a tool having a diameter of 21 mm, and rotating the tool at 3,000 rpm and exerting a pressure of 150 kg on the tool for a period of two seconds against the surface of the yoke in the base of the drilled hole.
