著しく低下する傾向があった。In addition, even when using somewhat hard steel,
Since the power supply lead wire and the end of the rotor winding are joined by brazing at the upper part of the lead length, the hardness of the brazed portion tends to decrease significantly due to the influence of this heat.
上記のような構造と傾向を第４図〜第９図を用いて具体

ら構成される。FIG. 9 is a cross-sectional view schematically showing a rotating electric machine, in which a rotor (30) supported at both ends by bearings (20) is connected to a rotating shaft (40) having a rotor core and a slot groove in the core. In order to support the laminated rotor winding and the end winding part (50) whose head partially protrudes from the rotor core in the axial direction at the end of the rotor winding, the rotating shaft is heated. It consists of a fitted support ring (60).

側に位置する固定子枠（１３０）から支えられている。The stator coil (110) is supported by the core within a slot provided in the core (120), and the core is supported from a stator frame (130) located on the outer diameter side of the core.

相互に接続される。In FIGS. 4 and 5, the rotating chain has a slot groove (2) (not shown in FIG. 4) on its surface in which the rotor winding is housed, and the rotor winding is housed in the slot groove (2). The windings are interconnected to form magnetic poles at the axial ends of the rotor.

う接作業は第８図に示すようにしておこなわれている。The connected rotor windings are connected to a power supply lead wire (4) at their winding ends (3), and this lead wire (4) is connected to the inner circumferential side of the mutually connected winding ends. It is then passed through the center hole (5) of the rotor (1). (6) is the rotor (
1) is a support ring that is fired after the winding connection work at the end. The winding end (3) and the lead wire (4) are connected as shown in FIG. That is, the winding end (3) is guided approximately perpendicularly to the circumferential direction of the rotor (1), and is brazed to the end of the lead wire (4) at that end. The lead wire (4) has a rising portion (4a) due to its structure, and at the tip of this rising portion (4a),
It is soldered to the winding end (3). Conventionally, this soldering work has been carried out as shown in FIG.

縮硬度が低下する性質を備えているために、その金属軟
化の範囲を小さく押えるためである。That is, a cooling section is constructed by leaving a certain dimension X from the waxed portion of the lead wire, and the work is performed while performing cooling in this section. This is because the lead wire (4) uses a copper alloy plate material to satisfy electrical performance, and the heat applied to the copper alloy during soldering softens the metal and reduces compression hardness. This is because the range of metal softening can be kept small because it has the property of softening metal.

It is known that the relationship between stress and strain that occurs when heat is applied to around 10°C is as shown in Figure 7. That is, when affected by heat, a small amount of stress causes a large strain.
このように熱によって金属軟化したリード線は回転子の
高速回転によって、特にその立上り部（４ａ）で大きな
遠心力が作用し、圧縮ひずみが発生して長期間の運転中
にその圧縮ひずみが蓄積されることになる。Due to the high-speed rotation of the rotor, a large centrifugal force acts on the lead wire whose metal has been softened by heat, especially at the rising portion (4a), causing compressive strain, which accumulates during long-term operation. will be done.

常変形や遠心圧縮力による塑性ちぢみなどの問題があっ
た。The above-mentioned technology does not take into account the ability to withstand centrifugal force when used in the rotor of a rotating electric machine where large centrifugal force acts, and it may cause abnormal deformation of the power supply lead wire due to excessive centrifugal force or centrifugal compression force. There were problems such as plastic shrinkage.

られる熱で金属軟化を生ずる部分が限定される。Above 41! According to a rotating electric machine having a rotor winding outlet according to Bo, the lead wire, which is inevitably formed due to the structure of the winding, further undergoes metal softening due to the heat applied by the braze phase connection that is inevitably performed. Parts are limited.
そして、特に銅合金の板材で製造されるリード線の立上

回転による遠心力が作用してもその力に抗して塑性変形

Even if centrifugal force due to rotation is applied, plastic deformation will not occur against that force.

) can completely prevent the metal from softening due to the heat of the wax at the rising portion (11).
而して、ろう接拡散部分（１５）はある程度の大きさと

First, one end (17a) of the crossover wire (17) is combined with this winding end (step 6), and while the combined portion is heated, wax is infiltrated into the joint surface to firmly secure the connection. Next, bring the pre-formed lead wire (work 0) and assemble it into the rotor, align it with the soldered surface (14
) and the other end (17b) of the crossover line (17). Thereafter, a device for absorbing and cooling the heat applied for brazing is attached to the wax liquid heat diffusion part of the lead wire (10).

ない。This can be done by wrapping an aluminum pipe filled with water, or by attaching a good heat conductor and then forcibly cooling the good heat conductor using a separate cooling device. Then, brazing similar to the above-described joining of the winding end (16) and one end (17a) of the crossover wire (17) is performed. If such a connection method is adopted, the heat applied for brazing is not transmitted to the rising portion (11) of the lead wire (10) formed of a plate material, so that metal softening due to heating does not occur.
