Fig. 1 is a cross-sectional view of the inner ring of the ball bearing according to this invention, Fig. 2 is a view showing the contact area between the balls and the thin wall portion,
Fig. 3 is an example of a case in which the undercut is not removed all the way to the side of the inner ring, but a portion is left, and Fig. 4 is a cross-sectional view of a ball bearing using the inner ring according to this invention. , Fig. 5 shows the shape of the contact surface between the balls and raceway and the distribution of contact stress when an axial load is applied to the ball bearing, and Fig. 6 shows the shape of the contact surface between the balls and the raceway and the distribution of contact stress. Fig. 7 is a diagram of the shape and stress distribution of the contact surface in a state where the contact surface runs on the shoulder part, Fig. 7 is an example diagram when an R part is provided to prevent stress concentration at the boundary between the raceway part and the shoulder part, and Fig. 8 is the same. FIG. 3 is a diagram showing an embodiment in which raceway surfaces are combined with two types of radii of curvature R 1 and R 2 in order to prevent stress concentration at the boundary between the raceway and the shoulder. 1... Ball bearing inner ring, 2... Inner ring raceway surface, 3...
