Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a rotor of a rotating electric machine characterized by a coil end support mechanism that protrudes from an end of the rotor of the rotating electric machine.

[Prior Art] A rotor of a conventional rotating electric machine of this type has a principal structure as shown in FIG. That is, end plates 3 are arranged on both sides of the iron core 2 attached to the rotating shaft 1 to prevent the iron core 2 from falling down and to fix the iron core 2, and a coil end support is placed on the outside of the end plate 3. 4 is placed. The support body 4 is configured to support the coil end 5.

[Problems to be solved by the invention] By the way, in the conventional configuration shown in FIG. It is necessary to form a large number of communicating holes in the end plate 3 and the coil end support 4, which has the drawback of increasing the number of man-hours in manufacturing the rotor of the rotating electric machine.

[Means for Solving the Problems] The above-mentioned problem consists of an end plate in which a plurality of plates having the same planar shape as the laminated plates of the rotor core are laminated, and a peripheral edge of the plate having the same shape as one of the laminated plates of the end plate. A coil end support fixing member which is formed by bending a cylindrical part and is arranged with the cylindrical part facing the opposite side of the rotor core, and a coil end inner peripheral surface and the cylinder of the coil end support fixing member. This problem is solved by a configuration consisting of a cylindrical coil end support disposed between the outer circumferential surface of the shaped part and the cylindrical coil end support.

[Function] The structure of the core holding end plate can be automatically obtained mechanically in the same process as core processing without requiring man-hour-consuming machining.

[Embodiment] FIG. 2 is a sectional view showing the main structure of an embodiment of this invention, and 11 is a rotating shaft. Reference numeral 12 denotes an iron core, which is obtained by laminating materials obtained by punching steel plates, and has a winding storage slot (not shown) and a ventilation hole A' or a hole for passing through a tightening bolt on the periphery. etc. are formed. 13 is an end plate, and iron core 12
This is to firmly fix the iron core 12 from both sides with the tightening force of bolts, nuts, etc. (not shown) while preventing the iron core 12 from falling to the side. And this end plate 1
3 obtains the material using a punching device for the core 12.
That is, it is constructed by laminating a plurality of plate bodies 13a having the cross-sectional shape of the iron core 12 (same shape as the punched steel plate).
Reference numeral 14 denotes a coil end support fixing member, which will be explained in comparison with the single plate 13a constituting the end plate 13. It is made of the same material and has the same thickness, and does not require a slot punching process (not shown). A cylindrical portion 14a is formed by bending the outer peripheral edge using, for example, press processing means, and the cylindrical portion 14a is disposed facing the opposite side from the rotor core. Reference numeral 15 denotes a coil end support, which is made of resin mold, has a cylindrical shape, and is attached to the coil end support fixing member 14.
It is supported by the cylindrical part 14a of , with a flexible spacer 16 interposed therebetween. 17 is a rotor coil, the coil end of which is supported by the support body 15.

Note that the spacer 16 can also be omitted by utilizing the flexibility of the support body 15.

[Effects] As described above, in the configuration related to this invention shown in FIG. It must be obtained by laminating plates by the same means as the punched steel plate used as the material, and the coil end support fixing member is a plate having the same shape as the plate forming the end plate, except for the formation of the slot. With features such as forming a cylindrical part by bending the periphery of the body, the coil end support mechanism for the rotor of a rotating electric machine has an excellent effect of reducing processing costs compared to conventional mechanisms. have
