Patent ID: 6880247

Claim:
A method for forming a bearing apparatus comprising: providing a roller bearing having an inner ring with an inner circumferential surface, an inner ring radial end surface, and a chamfered corner having a chamfer radius X 2 and extending from an inner circumferential surface end point to said inner ring radial end surface; providing a hollow shaft body having: a shaft end; an internal splined portion having a spline pitch diameter y 1 and extending to toward said shaft end to a spline portion end point; and a spline free portion having a thickness y 2 extending from said spline portion end point to said shaft end; calculating a distance X 1 >X 2 (y 1 /y 2 ); positioning said inner ring on said hollow shaft such that said inner circumferential surface end point is distanced from said spline portion end point toward said shaft end by the distance X 1 ; and swaging said hollow shaft outward from a bending starting point aligned with said inner circumferential surface end point to said shaft end to fix said inner ring.
