Abstract

자석발전기의 회전자 제조방법에서, 요크(20)의 저벽(25)에 개설되어 있는 개구(26)의 주부는 결합부(27)가 요크의 내주측으로 돌출되도록 하기 위해 축방향 내부로 구부림 가공을 하는 것이 필수적이다. 그때 결합부(27)는 축방향 외부로 후방향 압착되기 위해 가소변형되어지고, 그래서 구부림 가공에 의해 형성된 만곡부(28)는 짧아지고 결합부의 높이(L1)는 축방향의 L2로 낮아진다. 내부톱니(29)는 결합부(27)의 내주상에 형성되고, 보스부재(11)의 외부톱니(18)는 내부톱니(29)에 결합되며, 구부림 조임부(17)는 보스부재의 선단상에 형성된다.In the rotor manufacturing method of the magnet generator, the main portion of the opening 26 formed in the bottom wall 25 of the yoke 20 is bent inward in the axial direction so that the coupling portion 27 protrudes to the inner circumferential side of the yoke. It is essential. At that time, the engaging portion 27 is plastically deformed to be squeezed outward in the axial direction, so that the curved portion 28 formed by the bending process is shortened and the height L1 of the engaging portion is lowered to L2 in the axial direction. The inner tooth 29 is formed on the inner circumference of the engaging portion 27, the outer tooth 18 of the boss member 11 is coupled to the inner tooth 29, the bending fastener 17 is the line of the boss member It is formed on a single phase.
