る層間絶縁である。In Figure 1, (1) is a commutator, (2 is a commutator (1)
(3) is a laminated iron core with a cap in which the armature coil is housed, (4) is a ring-shaped armature coil support that forms part of the armature body, and (5) is a A molded insulating part for the purpose of insulating between the armature coil (21 and the coil support (4)), (6) is a bind that tightens the armature coil (2), and (7) is an insulator between the layers of the armature fill (2). This is interlayer insulation.

ピッチだけずれるように構成されている。Generally, the molded insulating part (5) is attached to a coil support (5) as shown in Figure 2 (a) so that it can be easily attached to the armature body.
The circumference of 4) is divided into an appropriate number of equal parts, and in order to electrically supplement each of the equally divided cut surfaces, the 21st
As shown in Z(b), coil supports (4) are applied to the upper and lower layers, and the cut portions of the upper and lower layers are arranged to be offset from each other by an equal pitch.
次にこの従来の成形絶縁部品（５）の詳細を説明する。Next, details of this conventional molded insulating component (5) will be explained.

全硬化の成形絶縁部品（５）としていた。The conventional molded insulating part (5) is made of a polyamide sheet, asbestos cloth, or mica sheet made of semi-cured thermoplastic resin, especially on the outside diameter (4a) of the coil support (4).
), the coil support (4) was heated and pressure-molded into a channel-shaped shape similar to that of a horse-riding coil support (4) using a molding jig to form a completely cured molded insulating part (5).

形治具を製作、保管しなければならないという欠点があ
った。The molded insulating part (5) thus completed has no problem for mass-produced machines, but it poses a problem for machines that produce a wide variety of products in small quantities. In other words, in high-mix, low-volume production machines, even if the outer diameter dimension (3a) of the w1 armature core (3) is the same, the groove depth dimension (3b) in which the armature coil (2) is accommodated is often different, and accordingly. Outer diameter (4a) of fill support (4)
will also change. However, fully cured molded insulation parts (5
), if the outer diameter (4 m) of the coil support (4) changes even slightly, the molded insulating part (5) and the coil support (4) will not fit well, and the outer diameter (4a) of the coil support (4) will change. Accordingly, new molding jigs must be manufactured, and a large number of molding jigs must be manufactured and stored.

点があった。In addition, regardless of whether it is a large lid production machine or a high-mix low-volume production machine, in order to complete the molded insulating part (5) as a completely cured product, the molding jig must undergo repeated thermal deformation due to heating, stress deformation due to pressure, etc. It is necessary to have a structure that can sufficiently withstand
The molding jig itself also had the disadvantage of being very expensive.

性があった。Furthermore, the outer diameter (3a) of the armature core (3) is large, and due to equipment considerations, the armature coil (2) is attached to the armature core (3), and after the bind (6) is wound, vacuum impregnation treatment is performed. In cases where so-called total impregnation is not possible, the bond between the coil support (4) and the molded insulating part (5) depends on the coefficient of friction between them and the binding (
6), and due to deterioration over time after operation, the molded insulation parts (5), the winding insulation of the armature coil (2), the interlayer insulation (7), the binding (6), etc. If damage occurs, the connection between the coil support (4) and the molded insulating part (5) becomes loose, causing slippage in the local direction between the coil support (4) and the molded insulating part (5) during acceleration and deceleration.

とを目的として°いる。This invention was made in order to eliminate the drawbacks of the conventional products as described above, and it is possible to mold the molded insulating part into the desired shape while it is in a semi-hardened state, and to support the coil in a flexible state (4). By installing the equipment in It is an object of the present invention to provide a rotation Wfi that can be obtained and has the effect of reducing the manufacturing cost of the jig itself.

成形絶縁部品（８）に変える他は第１図と全く同じであ
る。Hereinafter, a molded insulating component which is an embodiment of the present invention will be described with reference to FIG. In No. 3 and 1, (8) is a molded insulating part molded in a semi-hardened state, and as for the overall armature structure, the conventional molded insulating part (5) is replaced with this semi-hardened molded insulating part (8). Other than the changes, it is exactly the same as Fig. 1.

される。Since such a molded insulating component (8) is in a semi-hardened state, it is much more flexible than the conventional fully hardened molded insulating component (5), so the outer diameter (4) of the coil support (4)
Even if the contact surface inner diameters of a) and the coil support (4) of the molded insulating part (8) are slightly different, attach the molded insulating part (8) to the coil support (4), and then attach the armature coil (2) to the coil support (4). When you attach it and wind up the bind (6), the military machine coil (
With the winding tension of the bind (6) through the coil support (4) and the molded insulating part (marked), a structure is obtained in which the coil support (4) and the molded insulating part (marked) are completely adhered both structurally and in terms of resin adhesion. , if the outer diameter (3a) of the armature core (3) is the same,
Even if the groove depth 3b) in which the armature coil (2) is accommodated changes and the outer diameter (4a) of the coil support (4) changes slightly, there is no need to manufacture a new molding jig; The reusability of tools is increased, and the number of molding jigs manufactured and owned is significantly reduced.

具はほとんど高温にさらされることがなくなり、加圧成
形時の圧力のみに耐えればよく、例えは従来の金型から
木型へ変え得るというように、成形治具自体の製作費も
著しく低減される。In addition, since molding is completed in a semi-hardened state, the molding jig is hardly exposed to high temperatures and only has to withstand the pressure during pressure molding, for example, when changing from a conventional mold to a wooden mold. As a result, the manufacturing cost of the molding jig itself is also significantly reduced.

い。In the above example, a mica sheet impregnated with a thermosetting resin is semi-cured during molding, but a mica sheet that has been previously treated to a semi-cured state may be molded by only applying pressure or by applying slight heat and pressure. It may be something.

It is also possible to consider a structure that allows

The armature coil (2) may be attached after the molded insulating component (8) and the coil support (4) are once bound together with a binding tape (9) such as a heat-shrinkable tape or a prepreg-treated tape thereof. Furthermore, after binding the molded insulating parts [F]) with the binding tape (9), the armature coil (2) may be attached after the molded insulating parts [F] are once heated and hardened.
