METHOD FOR MANUFACTURING CYLINDRICAL SHAFT |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a cylindrical shaft with a stabilized shape. <P>SOLUTION: The method for manufacturing the cylindrical shaft 16 includes: a cylinder working step of bending a metal plate cylindrically so that a pair of opposite end faces comes close or into contact with each other to form the cylindrical shaft 16 having a joint 80 between the pair of end faces extending in the axial direction; a bending working step of curving the cylindrical shaft 16 in the axial direction so that the joint 80 is on the inside of an arc; and a stress adjusting step of adjusting stress that remains in the cylindrical shaft 16 by adding external force to the cylindrical shaft 16. <P>COPYRIGHT: (C)2012,JPO&INPIT |
