Description

拘束具Restraint
　本発明は、複数本の繊維をテープ状に束ねた繊維束を環状に積層するように複数回巻回されてマトリックスとなる樹脂で一体的に結着された拘束具に関し、特に、発電機や電動機等の回転電機の回転子の磁石を拘束する場合に適用すると有効である。 The present invention relates to a restraint integrally wound with a resin serving as a matrix by being wound a plurality of times so as to cyclically laminate a fiber bundle in which a plurality of fibers are bundled in a tape shape, in particular, a generator or the like It is effective when applied to the case of restraining a magnet of a rotor of a rotating electrical machine such as a motor.
　例えば、発電機や電動機等の回転電機は、回転軸の外周を円環状に包囲するように磁石を配列された回転子が、円筒状の鉄心の外周にコイルを巻回された固定子の内部に回転可能に配置されている。上記回転子の上記磁石は、回転軸の回転に伴って、当該回転軸の径方向外側へ向かう大きな遠心力が加わることによる分解を防止するため、外周に環状の拘束具が取り付けられている。 For example, in a rotating electrical machine such as a generator or a motor, a rotor in which magnets are arranged to annularly surround the outer periphery of a rotating shaft is inside a stator in which a coil is wound around a cylindrical iron core. Are arranged rotatably. An annular restraint is attached to the outer periphery of the magnet of the rotor in order to prevent decomposition due to application of a large centrifugal force directed radially outward of the rotation shaft as the rotation shaft rotates.
　このような拘束具としては、例えば、図５Ａ，５Ｂに示すように、複数本の繊維１１をテープ状に束ねた繊維束１０を環状に積層するように螺旋状に複数回巻回されて端部１１ａを揃えるように巻終端１０ａを整えられてマトリックスとなる樹脂で一体的に結着されたものが知られている（例えば、下記特許文献１参照）。 As such a restraint, for example, as shown in FIGS. 5A and 5B, the fiber bundle 10 in which a plurality of fibers 11 are bundled in a tape shape is spirally wound a plurality of times so as to be annularly stacked. There is known one in which the winding end 10a is arranged so as to align the parts 11a and integrally bonded with a resin as a matrix (for example, see Patent Document 1 below).
特開２０１６－０８２７７３号公報JP, 2016-082773, A
　前述したような拘束具１においては、径方向内側へ磁石を押さえ付けるように当該磁石の外周に取り付けられることから、径方向外側へ拡径する方向の反力が加わると共に、繊維束１０の巻終端１０ａに周方向（長手方向）Ｌで引き戻される方向の応力Ｓが加わるようになる（図６Ａ参照）。 In the restraint tool 1 as described above, since the magnet is attached to the outer periphery of the magnet so as to press the magnet inward in the radial direction, a reaction force in the direction of diameter expansion outward in the radial direction is applied. The stress S in the direction of being pulled back in the circumferential direction (longitudinal direction) L is applied to the end 10 a (see FIG. 6A).
　このような応力Ｓが加わる繊維束１０の強度的な特異点となる巻終端１０ａにおいて、例えば、何らかの原因により一本の繊維１１Ｄの端部１１Ｄａが剥離してしまうと（図６Ｂ参照）、当該繊維１１Ｄに幅方向Ｗで隣接する他の繊維１１Ｃ，１１Ｅの端部１１Ｃａ，１１Ｅａに衝撃が加わると共に応力Ｓが集中して、当該繊維１１Ｃ，１１Ｅの端部１１Ｃａ，１１Ｅａも剥離してしまい（図６Ｃ参照）、以下、連鎖的に他の繊維１１Ａ，１１Ｂ，１１Ｆの端部１１Ａａ，１１Ｂａ，１１Ｆａも剥離していくことにより、拘束具１の強度低下を引き起こしてしまう場合があった。 For example, when the end 11Da of one fiber 11D is peeled off for some reason at the winding end 10a which is a strong singular point of the fiber bundle 10 to which such a stress S is applied, see the figure The impact is applied to the ends 11Ca and 11Ea of the other fibers 11C and 11E adjacent to the fiber 11D in the width direction W and the stress S is concentrated, and the ends 11Ca and 11Ea of the fibers 11C and 11E are also peeled off 6C), there is a case where the strength reduction of the restraint 1 is caused by peeling off the end portions 11Aa, 11Ba, 11Fa of the other fibers 11A, 11B, 11F in a chained manner.
　このような問題は、上述したような回転電機の回転子の磁石を拘束する拘束具に限らず、複数本の繊維をテープ状に束ねた繊維束を環状に積層するように複数回巻回されてマトリックスとなる樹脂で一体的に結着された拘束具であれば、上述した場合と同様にして生じ得ることであった。 Such a problem is not limited to the above-described restraint device that restrains the magnets of the rotor of the rotary electric machine, and is wound a plurality of times so that a fiber bundle in which a plurality of fibers are bundled in a tape shape is annularly stacked. In the case of the restraint which is integrally bound by the resin as the matrix, it can be generated in the same manner as described above.
　このようなことから、本発明は、繊維束の巻終端での繊維の端部の剥離に伴う強度低下を抑制することができる拘束具を提供することを目的とする。 From such a thing, an object of the present invention is to provide a restraint which can control a strength fall accompanying exfoliation of an end of a textiles at a winding end of a textiles bundle.
　前述した課題を解決するための、本発明に係る拘束具は、複数本の繊維をテープ状に束ねた繊維束を環状に積層するように複数回巻回されてマトリックスとなる樹脂で一体的に結着された拘束具において、前記繊維束の巻終端における前記繊維の端部の周方向の位置を当該繊維束の幅方向で異ならせる切欠き部が形成されていることを特徴とする。 A restraint according to the present invention for solving the above-mentioned problems is integrally wounded with a resin as a matrix so that it is wound a plurality of times so as to annularly laminate a fiber bundle in which a plurality of fibers are bundled in a tape shape. The restraining device is characterized in that a notch is formed to make the circumferential position of the end portion of the fiber at the winding end of the fiber bundle different in the width direction of the fiber bundle.
　また、本発明に係る拘束具は、上述した拘束具において、前記繊維束の前記切欠き部が、略Ｖ字形状をなしていることを特徴とする。 Moreover, the restraint according to the present invention is characterized in that, in the above-mentioned restraint, the notch portion of the fiber bundle has a substantially V shape.
　また、本発明に係る拘束具は、上述した拘束具において、前記繊維束の前記切欠き部が、略凹形状をなしていることを特徴とする。 Further, in the above-mentioned restraint device, the restraint device according to the present invention is characterized in that the notch portion of the fiber bundle has a substantially concave shape.
　また、本発明に係る拘束具は、上述した拘束具において、前記繊維束の巻終端が、当該繊維束の幅方向で階段構造となるように、前記繊維束の前記切欠き部が、略Ｌ字形状をなしていることを特徴とする。 Further, in the restraint device according to the present invention, in the above-mentioned restraint device, the notch portion of the fiber bundle is substantially L so that the winding end of the fiber bundle has a step structure in the width direction of the fiber bundle. It is characterized in that it has a letter shape.
　また、本発明に係る拘束具は、上述した拘束具において、前記繊維束の幅方向一方側の前記繊維の長手方向の長さが幅方向他方側の前記繊維の長手方向の長さよりも長くなるように、当該繊維束の前記巻終端が当該繊維束の幅方向に傾斜して形成されていることを特徴とする。 Further, in the restraint device according to the present invention, in the restraint device described above, the length in the longitudinal direction of the fiber on one side in the width direction of the fiber bundle is longer than the length in the longitudinal direction of the fiber on the other side in the width direction Thus, the winding end of the fiber bundle is formed to be inclined in the width direction of the fiber bundle.
　また、本発明に係る拘束具は、上述した拘束具において、回転電機の回転子の磁石を拘束するものであることを特徴とする。 A restraint according to the present invention is characterized in that, in the above-mentioned restraint, the magnet of the rotor of the rotary electric machine is restrained.
　本発明に係る拘束具によれば、繊維束の巻終端における繊維の端部の周方向の位置を当該繊維束の幅方向で異ならせる切欠き部が形成されていることから、隣接する繊維の端部の周方向の位置が離れるようになるので、繊維束のうちの一本の繊維の端部が何らかの原因で剥離してしまっても、当該繊維に隣接する他の繊維の端部に加わる衝撃や応力の集中を大きく抑えて、端部の剥離した繊維に隣接する繊維の端部の剥離を抑制することができ、繊維束の巻終端における繊維の端部の連鎖的な剥離を防止することができる。これにより、繊維束の巻終端での繊維の端部の剥離に伴う強度低下を抑制することができる。 According to the restraint device of the present invention, since the notch portion is formed to make the circumferential position of the end portion of the fiber at the winding end of the fiber bundle different in the width direction of the fiber bundle, Since the circumferential positions of the ends become apart, even if the end of one fiber of the fiber bundle is peeled off for some reason, it is added to the end of the other fiber adjacent to the fiber. The concentration of impact and stress can be largely suppressed to suppress peeling of the end of the fiber adjacent to the peeled fiber at the end, and to prevent chain peeling of the end of the fiber at the winding end of the fiber bundle be able to. Thereby, the strength reduction accompanying peeling of the end of the fiber in the winding end of a fiber bundle can be suppressed.
