PROBLEM TO BE SOLVED: To provide a rotor assembly device capable of surely performing the centering of a shaft.SOLUTION: Rotor assembly devices 1 and 2 are configured to fix a rotor core 22 onto a shaft 21 by holding the rotor core 22 between a nut 23 that is screwed to the shaft 21 and a flange 31 in the state where the shaft 21 including the flange 31 is inserted into a center hole 22a of the rotor core 22 that is formed by stacking steel sheets. The rotor assembly device comprises: a pedestal part 13 with which an opening 13a is formed for inserting an end 21a of the shaft 21 at a side of the flange 31; and axial force receiving parts 12 and 14 which are inserted into the opening 13a of the pedestal part 13 and support a plane part of the flange 31 of the shaft 21 or a distal end face of the end 21a of the shaft 21. Centers of openings of the axial force receiving parts 12 and 14 are matched with a center of the shaft 21.SELECTED DRAWING: Figure 1 |
