ていた。 Conventionally, the rotor yoke and center boss of a magnet generator have generally been coupled as follows. As shown in FIG. 1A, in the first step, a hole 5 is formed in the center of the rotor yoke 4 on the upper surface of the flange 2 of the center boss 1 and on the outer periphery of the cylindrical portion 3.
is press-fitted by the first press upper die 6. next second
In the process, as shown in FIG. 1B, when the second press upper die 8 is brought into contact with the stepped portion 7 of the center boss 1 and lowered, at the same time, the material of the stepped portion 7 flows in the direction of the arrow and is deformed protrudingly. At the final stage, the rotor yoke 4 is fixed to the center boss 1 by the protruding portion 9 that has been deformed as shown in FIG. 1C. Looking at the enlarged cross-sectional structure diagrams shown in FIGS. 1 and 2, the protrusion 9 bites into the rotor yoke 4, thereby deforming the plate thickness of the rotor yoke 4 and making it thinner. This phenomenon becomes more pronounced as the hardness of the material of the center boss 1 is higher than that of the rotor yoke 4. In this structure, the protruding part 9 bites into the rotor yoke and does not extend, and the effective diameter φ is small, and the rotor yoke 4 and center boss 1
The bond strength was weak. When the tightening pressure is increased in an attempt to increase the effective diameter φ, the protrusion 9 bites deeper into the rotor yoke 4 and the rotor yoke 4
Since it is deformed thinly, it has the disadvantage that it can break from this part, which is particularly an obstacle to improving bending fatigue strength.
本発明は、上記の欠点に鑑みなされたもので、

ものである。 The present invention has been made in view of the above-mentioned drawbacks.
The present invention provides a method for joining a rotor yoke and a center boss of a magnet generator, in which the effective diameter φ of the rotor yoke and center boss is increased by performing a single fitting process.

計者の広範囲な要求を可能とするものである。 Embodiments of the present invention will be described below based on the drawings. In the present invention, first, as shown in FIG. 2, A, the rotor yoke 4 is placed on the lower die 10,
The center boss 1 is set on the lowering upper mold 11.
Then, the outer periphery of the cylindrical portion 3 of the center boss 1 is pressed into the hole 5 provided in the center of the rotor yoke 4 and lowered. At the same time, the lower die 10 which has been abutted against the stepped portion 7 of the center boss 1 causes the material of the stepped portion 7 of the center boss 1 to flow in the direction of the arrow, causing it to protrude and elongate, as shown in FIG. As shown in FIG. 2C, when the upper mold 11 descends to the final stage, the protruding part 9 is moved toward the convex part 12 of the lower mold 10 (deformation prevention part of the eye part of the rotor yoke 4) with a slight gap at the base. The tip 9'' extends while pressurizing the rotor yoke 4, leaving the tip 9'.Since this protrusion 9 extends together with the rotor yoke 4 rising while being press-fitted, it is difficult to bite into the recess and deform it into a thin wall. The structure is not pressurized, as shown in the enlarged view shown in Figure 2, d. By using this method of joining, the effective diameter φ can be reduced to the conventional one without changing the wall thickness of the socket part. In addition, in order to increase the strength of the joint, the protrusion 9
Even if the wall thickness of the rotor yoke 4 is increased, as shown in the enlarged cross-sectional view shown in FIG. It makes it possible.
