Title:
The rotor for rotation electrical machinery
Document Type and Number:
Japanese Patent JP6148206
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a rotary electric machine rotor in which a decrease in fixing force in an axial direction to an end plate is prevented and which is advantageous in terms of cost.SOLUTION: A rotary electric machine rotor 1 comprises: a rotor shaft 10; an annular rotor core 20 provided on the outer circumference thereof; a pair of core holding portions 30 for holding the rotor core 20; and a projecting portion 40 formed so as to project radially outward in at least one of the pair of core holding portions 30. An annular end plate 50 having a keyway opened toward the inner peripheral side is provided between the projecting portion 40 and the rotor core 20. Furthermore, a movable piece 60 is held radially movably in the keyway 51. At least one of opposing surfaces of the end plate 50 and the movable piece 60 in the radial direction is inclined with respect to the axial direction X of the rotor shaft 10. The projecting portion 40 regulates the movement of the end plate 50 and the movable piece 60 in a direction away from the rotor core 20.
