Example

[0047] [First Embodiment]

[0048] (The structure of the rotor)

[0049] Refer Figure 1 ~ 14 The structure of the rotor 10 of the first embodiment will be described.

[0050] In the present application specification, "axial" refers to the direction along the rotation axis (reference numeral O) (Z1 direction, Z2 direction) of the rotor 10 (refer to figure 1 . Further, "circumferential" refers to the circumferential direction (A direction, A1 direction, A2 direction) of the rotor core 11. Further, the "radially inner" refers to the direction (B1 direction) toward the center of the rotor core 11. Further, the "radially outer" means the direction (B2 direction) toward the outer side of the rotor core 11.

[0051] like figure 1As shown, the rotary electric machine 100 includes a rotor 10 and a stator 20. The stator 20 contains a circular stator core 21. A plurality of slots 22 are provided at the stator core 21. Segment conductor 30 is disposed in a plurality of slot 22, respectively. ...

Example

[0106] [Second Embodiment]

[0107] Next, referring to figure 2 ,as well as Figure 15 ~ 23 The manufacturing method of the rotor 10 of the second embodiment will be described. In the manufacturing method of the rotor 10 of the second embodiment, the manufacturing apparatus 300 of the rotor 10 is different from the first embodiment of the hydraulic pressure cylinder 208 that is hydraulically driven, and the flexible variation is used. Further, in the same manner as the first embodiment, the same reference numerals as those of the first embodiment are illustrated and the description thereof will be omitted.

[0108] (Construction of the manufacturing apparatus of the rotor)

[0109] like Figure 15 As shown, the manufacturing apparatus 300 of the rotor 10 includes a mold 300A for hydraulic molding. Hydraulic molded mold 300A has a mold pressing portion 200b. The manufacturing apparatus 300 (300a, 200b) of the rotor 10 includes a shaft pressing member 201, and a core pressing member 2...

Abstract

The invention relates to a rotor manufacturing method and a rotor manufacturing device. This rotor manufacturing method is provided with steps of: pressing a rotor core in the central axis line direction by a core pressing member; and fixing a shaft to the rotor core by hydroforming for pressure-contacting the shaft to the inner circumferential surface of a shaft insertion hole in a state in which the rotor core is pressed.

Description

technical field [0001] The present invention relates to a rotor manufacturing method and a rotor manufacturing device. Background technique [0002] Conventionally, a rotor manufacturing method and a rotor manufacturing apparatus including a rotor core fixed to a shaft by hydroforming are known. For example, Japanese Patent Application Laid-Open No. 2001-268858 discloses such a rotor manufacturing method and a rotor manufacturing apparatus. [0003] The aforementioned JP-A-2001-268858 discloses a rotor for a motor including a hollow rotating shaft (shaft) having a pipe structure and a laminated iron core (rotor core) into which the rotating shaft is inserted. In addition, a drop-off preventing portion formed by hydroforming is provided on the rotating shaft. The retaining portion is formed by expanding the rotary shaft on the outer diameter side by hydroforming. In addition, two anti-slip portions are provided on one side and the other side of the laminated core in the ax...
