ROTOR AND METHOD FOR MANUFACTURING SAME

摘要

A rotor 10 of the invention includes a core 11 made of laminated steel sheets 21 and formed with a rotation-transmitting-member mounting end face (a wall surface of a through hole 26 for shaft) extending over a lamination direction and a rotation transmitting member (a shaft 12) mounted to the rotation-transmitting-member mounting end face of the core 11. The core 11 is formed with a welding end face (a wall surface of a through hole 25 for welding) extending over the lamination direction and in a position adjacent to a rotation-transmitting-member mounting end face. A welded trace 29 is formed in the welding end face, extending to the rotation transmitting member and over the lamination direction of the core 11. The invention can easily achieve size reduction and weight reduction of a rotary machine and manufacture a rotor in the reduced number of working processes.
