Title:
ASSEMBLY STRUCTURE OF END PLATE
Document Type and Number:
Japanese Patent JP2018121440
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve assembly workability of an end plate to a rotor shaft.SOLUTION: An end plate 21 is fastened to a rotor shaft 11 by screwing, and assembled while being regulated rotation for the rotor shaft 11 by a rotation regulating section A. The rotation regulating section A includes recesses 15 (locked parts), grooves 31 and locking parts 33. The recesses 15 are provided in the peripheral of the rotor shaft 11, at each equal angle in the hoop direction. The grooves 31 are provided in multiple places of different number from the recesses 15 in the hoop direction at each equal angle, so as to extend in the hoop direction at the intermediate part of the end plate 21, and at least one groove faces any recess 15 in the radial direction. The locking parts 33 projects from a part facing the recess 15 in the radial direction in the same radial direction, out of farther inner part than the groove 31 in the radial direction of the end plate 21, and is locked to the recess 15, thus regulating rotation of the end plate 21 for the rotor shaft 11.SELECTED DRAWING: Figure 2
