Abstract

PURPOSE: To reduce vibrational noises produced by irregular rotation of washers, by using three washers having different hardness in a set.
CONSTITUTION: Washers 41W43, 46W48 are interposed respectively between rotor 7 and radial bearings 3, 4 arranged on the fixed side of the structure, so as to restrict the axial position of rotor 7. Each three washers are used in a set, and outer washers 41, 43, 46, 48 are made of a relatively hard material and fixed tightly to the motor shaft 6 of rotor 7. On the other hand, inner washers 42, 47 are made of a relatively soft material and fitted loosely on motor shaft 6. Since, in the above arrangement, outer washers 41, 43, 46, 48 are rotated together with motor shaft 6, so that their irregular rotation is not caused. Thus, it is enabled to minimize generation of vibrational noises.
