Document Type and Number:
Japanese Patent JP2015116022
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a rotary electric machine rotor, in which rotor cores can be fastened to a rotor shaft by predetermined fastening force regardless of variation in dimensions in a shaft direction of the rotor cores.SOLUTION: A rotary electric machine rotor 10 comprises: rotor cores 20 constituted of laminated magnetic material thin plates; a rotor shaft 30 that has a receiving portion 32 contacting one end faces in a shaft direction of the rotor cores 20 at one end side thereof and has an outer diameter screw structure 40 at the other end side; and a nut portion 50 that is engaged with the outer screw structure 40 of the rotor shaft 30. With the nut portion 50 fastened to the outer diameter screw structure 40 of the rotor shaft 30 and the rotor cores 20 fastened to the rotor shaft 30, a contact face among the nut portion 50 and the rotor cores 20 is positioned closer to the other end in the shaft direction than the outer diameter structure 40.
