Description

本発明は計測配線の支持構造に関し、回転子の外周面に配線される計測配線を、良好に支持することができるように工夫したものである。   The present invention relates to a support structure for measurement wiring, and is devised so that measurement wiring wired on the outer peripheral surface of a rotor can be favorably supported.

突極形回転電機の回転子（突極形回転子）は、高速で回転すると共に高温になる（特許文献１参照）。このような突極形回転子の状況、例えば応力歪や発生温度を把握するために、突極形回転子に各種のセンサ（歪センサや、温度センサ等）を取り付けて、応力歪や温度を計測することが行われている。   A rotor of a salient pole type rotating electrical machine (salient pole type rotor) rotates at a high speed and becomes high temperature (see Patent Document 1). In order to grasp the situation of such salient pole rotors, for example, stress strain and generated temperature, various sensors (strain sensors, temperature sensors, etc.) are attached to the salient pole rotor, and the stress strain and temperature are adjusted. Measuring is done.

ところで、センサには、センサで検出した検出信号を外部に伝送するための計測配線（以下「リード線」と称することもある）が接続されている。しかし、突極形回転子は高速で回転するため、リード線には、遠心力による荷重が作用し、リード線が切断するおそれがあった。   By the way, a measurement wiring (hereinafter also referred to as “lead wire”) for transmitting a detection signal detected by the sensor to the outside is connected to the sensor. However, since the salient pole rotor rotates at a high speed, a load due to centrifugal force acts on the lead wire, which may cause the lead wire to be cut.

そこで、従来では、回転子の表面に溝や切り欠きを設けて、この溝内や切り欠き内にセンサやリード線を配置して、接着剤で固定すること等が考えられていた（特許文献２，３参照）。しかし、このように溝等を設けると、発生磁束が変化するおそれがあるという問題があった。   Therefore, conventionally, it has been considered that a groove or notch is provided on the surface of the rotor, a sensor or a lead wire is disposed in the groove or notch, and fixed with an adhesive (Patent Document). 2 and 3). However, when the groove or the like is provided in this way, there is a problem that the generated magnetic flux may change.

特に、突極形回転子の外周面（固定子の内周面に対向する湾曲面）に、リード線を配置する場合には、仮にリード線が切断等すると、切断等したリード線が固定子に接触する恐れがあった。また、突極形回転子の外周面に溝等を設け、この溝内にリード線を埋め込んだ場合には、溝を形成したことにより磁束が変化して、固定子に作用する磁束に大きな悪影響を与えてしまう可能性もあった。   In particular, when a lead wire is disposed on the outer peripheral surface of the salient pole rotor (the curved surface facing the inner peripheral surface of the stator), if the lead wire is cut, the cut lead wire is replaced with the stator. There was a risk of contact. In addition, when a groove or the like is provided on the outer peripheral surface of the salient pole rotor and the lead wire is embedded in the groove, the magnetic flux changes due to the formation of the groove, and the magnetic flux acting on the stator is greatly adversely affected. There was also a possibility of giving.

本発明は、上記従来技術に鑑み、突極形回転子の外周面に配線する計測配線（リード線）を、確実に支持することができると共に、磁束に悪影響を与えることのない、計測配線の支持構造を提供することを目的とする。   In view of the above-described prior art, the present invention can reliably support the measurement wiring (lead wire) wired on the outer peripheral surface of the salient pole rotor, and does not adversely affect the magnetic flux. The object is to provide a support structure.

Further, since the support wire is a non-conductive wire, even if the support wire is arranged, the magnetic flux is not affected.

以下、本発明に係る計測配線の支持構造を、突極形回転電機の回転子に適用した実施例に基づき詳細に説明する。   Hereinafter, the support structure of the measurement wiring according to the present invention will be described in detail based on an embodiment applied to a rotor of a salient pole type rotating electric machine.

先ず、突極形回転電機の構造を説明する。
図１に示すように、突極形回転電機１は、図示しないフレーム等に固定された略円筒状の固定子１０と、固定子１０の内周側に回転自在に保持された突極形回転子２０を有している。 First, the structure of the salient pole type rotating electric machine will be described.
As shown in FIG. 1, the salient pole rotating electrical machine 1 includes a substantially cylindrical stator 10 fixed to a frame or the like (not shown), and a salient pole rotation rotatably held on the inner peripheral side of the stator 10. It has a child 20.

突極形回転子２０の回転軸２１，回転子継鉄２２及び磁極突部２３は、一体的に形成されている。回転軸２１は、突極形回転子２０の回転中心となるものであって、その軸方向両端部が軸受（図示省略）により、回転可能に支持されている。回転軸２１の軸方向の中央部分には、回転子継鉄２２が、回転軸２１の周囲を覆いつつ軸方向に延在する状態で、一体的に形成されている。回転子継鉄２２の外周部のうち周方向に９０°ずれた位置には、磁極突部２３が一体的に形成されている。つまり、磁極突部２３は、回転子継鉄２２の外周部から径方向外側に向けて突出すると共に、周方向において等間隔で配置されている。   The rotating shaft 21, the rotor yoke 22, and the magnetic pole protrusion 23 of the salient pole rotor 20 are integrally formed. The rotating shaft 21 serves as the center of rotation of the salient pole rotor 20, and both axial ends thereof are rotatably supported by bearings (not shown). A rotor yoke 22 is integrally formed at the central portion of the rotating shaft 21 in the axial direction so as to cover the periphery of the rotating shaft 21 and extend in the axial direction. A magnetic pole protrusion 23 is integrally formed at a position shifted by 90 ° in the circumferential direction in the outer peripheral portion of the rotor yoke 22. That is, the magnetic pole protrusions 23 protrude radially outward from the outer periphery of the rotor yoke 22 and are arranged at equal intervals in the circumferential direction.

磁極突部２３の周面には、絶縁板（図示省略）を介して、界磁巻線（界磁コイル）２４が配置されている。界磁巻線２４は、板状をなす導体と板状をなす絶縁部材を径方向に交互に積層することによって構成されている。しかも、界磁巻線２４を構成する板状の導体のうち、積層方向に関して所定の間隔ごとのものは、磁極突部２３から見て外周側に伸びており、この伸びた導体部分が冷却フィン２４ａになっている。   A field winding (field coil) 24 is disposed on the peripheral surface of the magnetic pole protrusion 23 via an insulating plate (not shown). The field winding 24 is configured by alternately laminating plate-shaped conductors and plate-shaped insulating members in the radial direction. In addition, among the plate-like conductors constituting the field winding 24, those at predetermined intervals in the stacking direction extend to the outer peripheral side when viewed from the magnetic pole protrusion 23, and the extended conductor portion is a cooling fin. 24a.

磁極突部２３の頂面（径方向外側端面）には、磁極頭部２５が複数のボルト２６（図２参照）により固定されている。磁極頭部２５の外周面（固定子１０の内周面に対向する湾曲面）２５ａには、径方向に延びるボルト穴２５ｂが複数形成されており、このボルト穴２５ｂを介してボルト２６が、磁極頭部２５を磁極突部２３にボルト締めしている。磁極頭部２５の外周面２５ａは、湾曲面となっており、固定子１０の内周面との間に隙間（径方向に数ｍｍの隙間）が確保されている。
なお、磁極突部２３と磁極頭部２５により、磁極鉄心が形成されている。また、回転子継鉄２２と磁極突部２３と磁極頭部２５により、回転子鉄心が形成されている。 A magnetic pole head 25 is fixed to the top surface (radially outer end surface) of the magnetic pole projection 23 by a plurality of bolts 26 (see FIG. 2). A plurality of bolt holes 25b extending in the radial direction are formed on the outer peripheral surface (a curved surface facing the inner peripheral surface of the stator 10) 25a of the magnetic pole head 25, and the bolts 26 are connected via the bolt holes 25b. The magnetic pole head 25 is bolted to the magnetic pole protrusion 23. The outer peripheral surface 25a of the magnetic pole head 25 is a curved surface, and a clearance (a clearance of several millimeters in the radial direction) is secured between the outer peripheral surface 25a and the inner peripheral surface of the stator 10.
The magnetic pole core 23 is formed by the magnetic pole protrusion 23 and the magnetic pole head 25. The rotor yoke 22, the magnetic pole protrusion 23, and the magnetic pole head 25 form a rotor core.

界磁巻線２４の頂面（径方向外側端面）と磁極頭部２５の内周側面（径方向内側端面）との間には、絶縁リング２７が介在されている。絶縁リング２７は、矩形（長方形状）の枠状体である。   An insulating ring 27 is interposed between the top surface (the radially outer end surface) of the field winding 24 and the inner peripheral side surface (the radially inner end surface) of the magnetic pole head 25. The insulating ring 27 is a rectangular (rectangular) frame.

なお、周方向に隣接した界磁巻線２４間には、コイル押さえ部材（図示省略）が、軸方向の複数箇所に設けられている。   Note that coil pressing members (not shown) are provided at a plurality of positions in the axial direction between the field windings 24 adjacent in the circumferential direction.

次に、本実施例にかかる、計測配線の支持構造を説明する。
図２に示すボルト穴２５ｂ内には、各種のセンサ（歪センサや、温度センサ）が配置される。本例では、歪センサ３１を配置した例を、一例として説明する。歪センサ３１はボルト２６の頭部の頂面に取り付けられている。この歪センサ３１には、歪センサ３１により検出した検出信号を伝送するための、リード線Ｌ１が接続されている。このリード線Ｌ１は、後述する支持線Ｌ２により支持されつつ、磁極頭部２５の外周面２５ａに密着しつつ周方向に沿い配線され、冷却フィン２４ａの先端部分で緊縛され（詳細は後述）、回転軸２１側に向かって引き回されている。 Next, a support structure for measurement wiring according to the present embodiment will be described.
Various sensors (a strain sensor and a temperature sensor) are arranged in the bolt hole 25b shown in FIG. In this example, an example in which the strain sensor 31 is arranged will be described as an example. The strain sensor 31 is attached to the top surface of the head of the bolt 26. A lead wire L1 for transmitting a detection signal detected by the strain sensor 31 is connected to the strain sensor 31. The lead wire L1 is wired along the circumferential direction while being in close contact with the outer peripheral surface 25a of the magnetic pole head 25 while being supported by a support wire L2 which will be described later, and is bound at the tip of the cooling fin 24a (details will be described later). It is routed toward the rotating shaft 21 side.

支持線Ｌ２は、非導電性、高耐熱性で引張強度の高いワイヤ線であり、例えば、芳香族ポリアミド系樹脂からなる線材（登録商標名「ケブラー」）を採用している。ボルト穴２５ｂ内にはリング付ボルト３２が固定設置されている。支持線Ｌ２は、その一端がリング付ボルト３２に固定され、その他端が冷却フィン２４ａに固定され、磁極頭部２５の外周面２５ａに密着しつつ周方向に沿い配線されている。   The support wire L2 is a wire wire that is non-conductive, highly heat resistant, and has high tensile strength. For example, a wire rod (registered trademark “Kevlar”) made of an aromatic polyamide resin is employed. A bolt 32 with a ring is fixedly installed in the bolt hole 25b. One end of the support line L2 is fixed to the ring-mounted bolt 32, the other end is fixed to the cooling fin 24a, and the support line L2 is wired along the circumferential direction while being in close contact with the outer peripheral surface 25a of the magnetic pole head 25.

リード線Ｌ１は、磁極頭部２５の外周面２５ａに密着しつつ配線されている部分では、支持線Ｌ２により支持されている。即ち、図３に示すように、支持線Ｌ２にリード線Ｌ１を螺旋状に巻きつけたり、図４に示すように、支持線Ｌ２とリード線Ｌ１を接触させて並べ両線Ｌ１，Ｌ２の外周面に固定テープであるガラステープ３３を螺旋状に巻き付けて固定して絶縁性樹脂（図示省略）で固めたりする、固定構造（リード線Ｌ１を支持線Ｌ２に固定する固定構造）により、支持線Ｌ２によりリード線Ｌ１を支持している。   The lead wire L1 is supported by the support wire L2 in the portion wired while being in close contact with the outer peripheral surface 25a of the magnetic pole head 25. That is, as shown in FIG. 3, the lead wire L1 is spirally wound around the support wire L2, or as shown in FIG. 4, the support wire L2 and the lead wire L1 are arranged in contact with each other, and the outer circumferential surfaces of both the wires L1, L2 A fixing structure (fixing structure for fixing the lead wire L1 to the supporting wire L2), in which the glass tape 33, which is a fixing tape, is spirally wound and fixed, and is hardened with an insulating resin (not shown). Thus, the lead wire L1 is supported.

なお、図３に示すように、支持線Ｌ２にリード線Ｌ１を螺旋状に巻きつける場合には、支持線Ｌ２として、非導電性、高耐熱性で引張強度が高いのみならず、非磁性特性を有するものを使用すれば、リード線Ｌ１に対する磁気的な悪影響を最小限にすることができる。   As shown in FIG. 3, when the lead wire L1 is spirally wound around the support wire L2, the support wire L2 has not only non-conductive properties, high heat resistance and high tensile strength, but also non-magnetic properties. If the one having the above is used, the magnetic adverse effect on the lead wire L1 can be minimized.

図５に示すように、冷却フィン２４ａには孔３４が形成されている。そして冷却フィン２４ａのうち最も外周側に位置する冷却フィン２４ａでは、支持線Ｌ２の他端が孔３４に挿入されて冷却フィン２４ａに緊縛・固着されている。   As shown in FIG. 5, a hole 34 is formed in the cooling fin 24a. And in the cooling fin 24a located in the outermost periphery side among the cooling fins 24a, the other end of the support line L2 is inserted in the hole 34, and is fastened and fixed to the cooling fin 24a.

歪センサ３１から引き出されたリード線Ｌ１は、支持線Ｌ２により支持されつつ磁極頭部２５の外周面２５ａに密着して周方向に沿い配線された後は、図５に示すように、最外周側の冷却フィン２４ａに近づいたところで、支持線Ｌ２から分かれる。支持線Ｌ２から分かれたリード線Ｌ１は、各冷却フィン２４ａの先端部分に接触しながら、回転軸２１側に向かって引き回されている。
各冷却フィン２４ａの孔３４には、非導電性、高耐熱性の緊縛紐３５が挿入・設置されており、この緊縛紐３５が、回転軸２１側に向かって引き回されているリード線Ｌ１を、緊縛して固定している。 After the lead wire L1 drawn from the strain sensor 31 is supported by the support wire L2 and closely contacts the outer peripheral surface 25a of the magnetic pole head 25 and is wired along the circumferential direction, as shown in FIG. When it approaches the cooling fin 24a on the side, it is separated from the support line L2. The lead wire L1 separated from the support wire L2 is routed toward the rotating shaft 21 while contacting the tip portion of each cooling fin 24a.
A non-conductive, high heat-resistant binding string 35 is inserted and installed in the hole 34 of each cooling fin 24a, and the binding line 35 is led toward the rotating shaft 21 side. Is fixed and fixed.

このように本例では、リード線Ｌ１は、磁極頭部２５の外周面２５ａに密着して周方向に沿い配線されている部分では、支持線Ｌ２により支持されている。このため、突極形回転子２０が高速で回転しても、リード線Ｌ１が切断する恐れがなくなる。また、支持線Ｌ２は、非導電性であるため、発生する磁束に悪影響を与えることはない。   As described above, in this example, the lead wire L1 is supported by the support wire L2 in the portion that is in close contact with the outer peripheral surface 25a of the magnetic pole head 25 and is wired along the circumferential direction. For this reason, even if the salient pole rotor 20 rotates at a high speed, there is no possibility that the lead wire L1 is cut. Further, since the support line L2 is non-conductive, it does not adversely affect the generated magnetic flux.

本実施例では、磁極突部２３に磁極頭部２５をボルト付けしたタイプの突極形回転子２０を対象としたが、本発明は、磁極突部及び磁極頭部（つまり、磁極鉄心）が一体的に形成されているタイプの突極形回転子にも適用することができる。
また、センサとしては、歪センサ３１のみならず、他のタイプの各種のセンサのリード線を支持する場合にも、本発明を適用することができる。 In the present embodiment, the salient pole rotor 20 of the type in which the magnetic pole head 25 is bolted to the magnetic pole protrusion 23 is targeted. However, in the present invention, the magnetic pole protrusion and the magnetic pole head (that is, the magnetic core) are provided. The present invention can also be applied to a salient pole rotor of the type formed integrally.
Further, the present invention can be applied not only to the strain sensor 31 but also to supporting various types of sensor lead wires as sensors.

本発明は、各種タイプの突極形回転子の磁極鉄心の外周面（固定子の内周面に対向する湾曲面）に、センサから引き出された計測配線（リード線）を配線する場合に、利用することができる。   The present invention, when wiring measurement wiring (lead wire) drawn from the sensor to the outer peripheral surface (curved surface facing the inner peripheral surface of the stator) of the magnetic core of various types of salient pole rotors, Can be used.
