| titleOfInvention | Hollow shaft with projection and manufacturing method thereof |
| abstract | (57) Abstract: Provided is a hollow shaft with a projection, in which the projection and the shaft have an integral shape, wherein the radius of curvature of the outer surface of the projection tip corner is equal to or less than the wall thickness of the base tube, and a method of manufacturing the same. A bulge is formed by a bulge process in a first step using a mold and divided into a movable mold for forming a protrusion and a movable mold for shaping a shaft. When the target radius of curvature of the outer surface of the corner portion in the axial direction at the tip of the protrusion is R, the formula "1.2−0.2 (R / t 0 ) ≦ (d 1 / d 2 ) (L 1 / L 2 ) ≦ 1.4 ”, the first step of bulging and the second step of bulging are performed. Here, t 0 is the wall thickness of the raw tube, d 1 is the outer peripheral length at the axial center position of the bulging portion, L 1 is the outer surface line length in the coaxial direction, d 2 is the outer peripheral length at the axial center position of the projection, L 2 Is the outer surface line length in the coaxial direction. |
