Description of the Related Art Conventionally, when a rotor and a stator of an electric motor are formed of laminated iron cores and fixed to a rotary shaft and a frame, they are fixed by press fitting or shrink fitting. That is, in the case of a rotor, a ring-shaped iron core piece is punched out from a thin steel plate and a predetermined number of the iron core pieces are laminated to form a hollow cylindrical laminated iron core. The rotary shaft is machined to have an outer diameter slightly larger than the shaft hole formed in the center of the laminated iron core, and a tightening margin is provided. Such a rotary shaft is press-fitted into a shaft hole of the laminated core by a press or the like, or the laminated core is heated and shrink-fitted. Further, in the case of the stator, as in the rotor, a predetermined number of ring-shaped core pieces are laminated to form a hollow cylindrical laminated core. The inner diameter of the frame that fixes the stator is made slightly smaller than the outer diameter of the laminated iron core to provide a tight margin, and the laminated iron core is press-fitted inside the frame.
The frame is heated and shrink-fitted.

供することを目的とするものである。However, in the prior art, when the laminated length of the laminated iron core is long or the variation of the tightening margin is large, seizure occurs between the laminated iron core and the rotary shaft or the frame during the press-fitting. This may result in difficulty in press-fitting, or deterioration in the squareness between the end surface of the laminated core and the rotating shaft or frame. Further, in the case of shrink fitting, since it is necessary to heat the rotary shaft or the frame, there is a problem that the heating furnace and the equipment cost for temperature control are high, and the assembling time is long. It is an object of the present invention to provide a method of fixing a laminated core that simplifies the work of fixing the laminated core and a fitting member such as a rotating shaft or a frame.

In a method of fixing a laminated core to be fitted, core pieces having different inner diameters, each having an inner diameter or an outer diameter processed to have a diameter larger or smaller than a diameter of a fitting portion of the fitting member, are provided, and the diameters are different from each other. An iron core piece is alternately laminated to form a laminated iron core having an engaging portion and a concave portion,
The fitting portion of the fitting member is press-fitted into the laminated core while the engaging portion of the laminated core with the fitting member is deformed to the recess side. Further, the engaging portion of the laminated core is formed by a protrusion protruding inward or outward. Further, a synthetic resin is injected and cured in a gap formed between the fitting member and the laminated iron core.

While being plastically deformed, a constant frictional force is maintained between the fitting member and the core piece due to the elasticity of the core piece. Further, since the protrusion is provided inside or outside the iron core piece that engages with the fitting member, when the fitting member is press-fitted into the axial hole or the outer periphery of the laminated core, the protrusion plastically deforms while having elasticity, A constant frictional force is maintained between the fitting member and the core piece due to the elasticity of the core piece.

Since there are the recesses 22 adjacent to each other, the inside of the inner diameter d 1 of the iron core piece 1A is plastically deformed while having elasticity so as to fall into the recess 22, and between the rotating shaft 3 and the iron core piece 1A, the iron core piece 1A is formed. Due to the elasticity of the engaging portion 23, a constant frictional force is maintained. Therefore, even if there is a variation in the tightening margin, a frictional force due to a certain elasticity generated by the deformation of the inner diameter portion of the iron core piece 1A acts, so that the fitting portion 31 and the iron core piece 1A are not excessively generated. No image sticking occurs.

In the figure, 4B is a ring-shaped iron core piece having a plurality of slots 41 on its inner circumference. 4C has the same outer diameter d as the core piece 4B
2 to multiple locations slightly outward (eg 0.5-1m
m) An iron core piece having a protruding portion 42 protruding. Reference numeral 5 denotes a laminated iron core that constitutes a stator formed by laminating the iron core pieces 4B, and the iron core pieces 4C having the protrusions 42 are inserted and laminated every time several iron core pieces 4B are laminated. 6 is a frame,
The fitting portion 61 into which the laminated iron core 5 is fitted is processed to have an inner diameter D 3 that is larger than the outer diameter D 4 of the protrusion 42 of the iron core piece 4C and smaller than the outer diameter D 2 of the iron core piece 4B. Therefore, the engaging portion 53 of the iron core piece 4A described in the second embodiment is replaced with the protrusion 42.
Almost the same as that formed by, but a recess 54 extending in the axial direction is formed. When the frame 6 is press-fitted onto the outer periphery of the laminated iron core 2, the protrusions 42 having the outer diameter d 6 have the inner diameter d 8
The frame 6 is pushed down in the axial direction by the fitting portion 61 and is plastically deformed while having elasticity, and a constant frictional force is maintained between the frame 6 and the iron core piece 4C by the elasticity of the protrusion 42. In the third and fourth embodiments described above,
Since the protrusion provided on the iron core piece is deformed to fix the iron core piece and the rotating shaft or the frame, a slight gap is formed between the iron core piece and the rotating shaft or the frame, but as shown in FIG. The heat-resistant synthetic resin 8 may be injected or dipped into the gap from the recess extending in the axial direction to be cured. Thereby, the fixing force between the laminated iron core and the rotating shaft or the frame can be further increased. Further, in the above-described embodiment, the description has been made of the one in which the protrusion is provided on the inner circumference or the outer circumference of the iron core piece, and the deformation is performed by pressing it against the fitting member such as the rotating shaft or the frame, but instead of the iron core piece having the protrusion. It is also possible to use an iron core piece having the same outer diameter or inner diameter as the tip of the protruding portion and having no protruding portion.

Since the piece is deformed and the elasticity of the iron core piece maintains the frictional force between the laminated iron core and the rotary shaft or the frame, an unreasonable force does not occur during press-fitting and seizure does not occur. In addition, since heating is not performed for shrink fitting, the facility cost for heating does not increase, and the assembly work time can be greatly reduced.
