    摘要: In a heat treatment wherein a blank to be used in the manufacture of bearing is (intermediate material) formed with a lubrication hole is heated and quenched, the quenching of the blank is terminated at the point of time that a temperature at a portion corresponding to a depth from a raceway surface (surface of a bearing part) of an outer ring (the bearing part), to which depth the maximum shear stress affects, is lowered to an MS point.

    摘要: In a bearing apparatus having a bearing (12) and a shaft body (11), the bearing being mounted to the shaft body such that the bearing (12) fits an outside of the shaft body (11), the bearing being prevented from dropping off by holding a caulked portion (13) against an outer end face of an inner ring of the bearing, and the caulked portion being formed by bending a cylindrical portion to be caulked of the shaft body outward in a diameter direction, an axial force controlling method controls an axial force applied to the bearing through the caulked portion by setting a relationship between relative positions (A,B) in an axial direction of an end edge on an inner periphery side of a chamfered portion formed at an inner peripheral shoulder portion of the inner ring and a caulking starting point on an inner periphery side of a cylindrical portion to be caulked.

    摘要: A bearing (12) is mounted to a hollow shaft provided to a hub wheel (11). A shaft end of the hollow shaft (14) is deformed radially outward and caulked to an outer end face of an inner ring of the bearing. Between a first area in which a spline portion is formed and a second area in which a caulked portion (14a) is formed between a bending starting point for bending the shaft end radially outward and an end face of the shaft end on an inner peripheral face of the hollow shaft, a third area for suppressing deformation of the inner peripheral face of the hollow shaft caused by the caulking is formed. The third area (143) cushions deformation in the first area.
