Abstract

PURPOSE:To mold a work member by rolling to make the depth of a groove uniform in the circumferential direction, by forming the outside circumferential face of a roll die to a noncircular shape provided with a flank in a rolling device where the distance between rotation axes of roll dies is kept constant. CONSTITUTION:In case that a shaft member 1 provided with, for example, a spiral groove 11 for generation of dynamic pressure, a herring-bone groove 12, or the like is worked by rolling, a marking and supporting roll dies 2 and 3 and a work rest 4 of a rolling device 5 are fixed in accordance with the member 1. The die 2 is provided with a noncircular outside circumferential face 24 consisting of a rolling working face 22, which is formed on the partial cylindrical face having a radius (r) from the axis f the die 2 and has a length W in the circumferential direction, and a flank 23 which has a radius shorter than the radius (r) and has a length C in the circumferential direction. Faces 22 and 23 are connected smoothly and are provided with a projecting marking part 21 for forming the groove on the member 1. In rolling, when the face 23 is allowed to face to the axis of the die 3 and the member 1 is inserted on the rest 4 and dies 2 and 3 are rotated, the member 1 is rolled and molded between faces 22 and 31, and the member 1 is taken out when the die 3 is returned to the original position.
