Abstract

PURPOSE:To cause no strange noise and to install a positioning annulus smoothly by forming a recessed section to the periphery of a rotating shaft for a rotor and by forcibly fitting the outside circumference of the positioning annulus to this recessed section. CONSTITUTION:A rotor 8 is formed by laminating plural iron plates where inserting holes of a rotating shaft 7 are provided in the center. Plural iron plates situated on the outside circumferential side of the rotor 8 have diameters greater than the inserting holes above and a recessed section 40 is formed on the external surface of the rotor 8. A positioning annulus 36, a buffering washer 37 and a thrust washer 36 to adjust the slice of the rotating shaft are inserted to the rotating shaft 7. In a positioning annulus 36 the inside diameter is formed greater than the outside diameter of an abrasive section 35 of the rotating shaft 7 and the outside diameter ic formed greater than the inside diameter of the recessed section 40 of the rotor 8. Consequently, in inserting the positioning annulus into the rotating shaft, no inside circumference of the positioning annulus is pressure-welded to the rotating shaft while moving the rotating shaft, but the outside circumference of the positioning annulus is pressure- welded and fixed to inside the recessed section of the rotor. Installation can thereby be facilitated.
