Abstract
Abstract An annular shoulder which retains a bearing race in a bore is deformed in two steps in each of which the annular, beveled edge of a staking anvil is pressed into a groove which defines one side of said shoulder. In the first deforming step the staking side of the beveled edge of the staking anvil is disposed at an angle of 45* relative to the axis of the aforesaid bore. In the second deforming step the staking side of the beveled edge of the staking anvil is disposed at an angle of 60* relative to said bore axis, and greater pressure is exerted against the shoulder.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
117 words
In the process of securing a bearing race within a bore in a housing by deforming a shoulder defined on one of said race and said housing by an annular V-shaped groove therein, the steps of: initially deforming said shoulder by pressing the annular, beveled edge of a first staking anvil into said groove, the staking side of said edge being disposed at an angle of about 45* relative to the longitudinal axis of said bore; and then deforming said shoulder by pressing the annular, beveled edge of a second staking anvil into said groove, the staking side of said edge being inclined at an angle of about 60* relative to the longitudinal axis of said bore.
Claim 2
Dependent Claim
117 words
In the process of securing a bearing race within a bore in a housing by deforming a shoulder defined on one of said race and said housing by an annular V-shaped groove therein, the steps of: initially deforming said shoulder by pressing the annular, beveled edge of a first staking anvil into said groove, the staking side of said edge being disposed at an angle of about 45* relative to the longitudinal axis of said bore; and then deforming said shoulder by pressing the annular, beveled edge of a second staking anvil into said groove, the staking side of said edge being inclined at an angle of about 60* relative to the longitudinal axis of said bore.
Claim 3
Dependent Claim
30 words
The process of claim 1 wherein: the pressure applied to said shoulder by said second staking anvil is greater than that applied to said shoulder by said first staking anvil.
Claim 4
Dependent Claim
28 words
The process of claim 1 wherein: said shoulder is formed on said race; and said race is supported on a support anvil while said shoulder is being deformed.
Claim 5
Dependent Claim
213 words
In the process of securing the race of a spherical bearing within a bore in a housing by deforming a shoulder defined on said race by an annular V-shaped groove concentrically spaced from the peripheral edge thereof, the steps of: supporting the side of said race which is remote from said shoulder on a support anvil having a cylindrical centering post which fits snugly within the aperture in the rotatable member of said bearing; initially deforming said shoulder by pressing the annular beveled edge of a first staking anvil into said groove, the staking side of said edge being inclined at an angle of about 45* relative to the longitudinal axis of said bore, said first staking anvil including a cylindrical centering post which is coaxial with said edge and which fits snugly within the aperture in the rotatable member of said bearing; and then deforming said shoulder by pressing the annular, beveled edge of a second staking anvil into said groove, the staking side of said edge being inclined at an angle of about 60* relative to the longitudinal axis of said bore, said second staking anvil including a cylindrical centering post which is coaxial with said edge and which fits snugly within the aperture in the rotatable member of said bearing.
Claim 6
