〈第一番目の実施形態〉
本発明に係る回転電機の仮固定治具及びこれを使用する回転電機の組立方法の第一番目の実施形態を図１〜６に基づいて説明する。 <First embodiment>
A first embodiment of a temporary fixing jig for a rotating electric machine according to the present invention and a method for assembling a rotating electric machine using the same will be described with reference to FIGS.

本実施形態に係る回転電機の仮固定治具は、図１〜３に示すように、ステータを取り付けた円筒形のフレームに対してロータを仮固定する回転電機の仮固定治具であって、フレームの一端側に基端側を着脱可能に取り付けられて先端側をロータへ着脱可能に連結される板状の支持部材であるブラケット１１と、ブラケット１１の先端側とロータとの間に着脱可能に配設される座部材であるスペーサ１２と、ブラケット１１の先端側及びスペーサ１２を貫通してロータに着脱可能に螺合する仮固定ボルト１３とを備えると共に、さらに、ブラケット１１の基端側をフレームの一端側に着脱可能に取り付ける取付ボルト１４（図４参照）を備えている。   The temporary fixing jig of the rotating electric machine according to the present embodiment is, as shown in FIGS. 1 to 3, a temporary fixing jig of the rotating electric machine for temporarily fixing the rotor to a cylindrical frame to which a stator is attached, A bracket 11 which is a plate-like support member having a base end detachably attached to one end of the frame and a distal end detachably connected to the rotor, and being detachable between the distal end of the bracket 11 and the rotor. And a temporary fixing bolt 13 that penetrates through the distal end side of the bracket 11 and the spacer 12 and is detachably screwed to the rotor, and further includes a base end side of the bracket 11. Is attached to one end of the frame in a detachable manner.

ブラケット１１は、背面（図１Ａ中、紙面奥面、図１Ｂ中、右面）の先端側（図１Ａ，図１Ｂ中、下側）に、厚肉となる台座部１１ａが設けられ、厚さ方向（図１Ａ中、紙面垂直方向、図１Ｂ中、左右方向）へ仮固定ボルト１３を差し込まれるボルト穴１１ｂが形成されると共に、基端側（図１中、上側）に、厚さ方向へ取付ボルトを差し込まれるボルト穴１１ｃが形成されている。   The bracket 11 is provided with a pedestal portion 11a having a large thickness at a front end side (lower side in FIGS. 1A and 1B) of a rear surface (in FIG. 1A, a back surface in FIG. 1B, right side in FIG. 1B), and has a thickness direction. A bolt hole 11b into which the temporary fixing bolt 13 is inserted is formed in the direction perpendicular to the paper surface of FIG. 1A (in the direction perpendicular to the plane of FIG. 1B, in the horizontal direction in FIG. 1B), and is attached in the thickness direction on the base end side (upper side in FIG. 1). A bolt hole 11c into which a bolt is inserted is formed.

スペーサ１２は、直方体形状をなし、ブラケット１１のボルト穴１１ｂと連絡して厚さ方向（図２Ａ中、紙面垂直方向、図２Ｂ中、左右方向）へ仮固定ボルト１３を差し込まれるボルト穴１２ｂが形成されている。   The spacer 12 has a rectangular parallelepiped shape, and has a bolt hole 12b into which the temporary fixing bolt 13 is inserted in the thickness direction (the direction perpendicular to the paper surface in FIG. 2A, the left-right direction in FIG. 2B) in contact with the bolt hole 11b of the bracket 11. Is formed.

仮固定ボルト１３は、頭部１３ａが、ブラケット１１のボルト穴１１ｂの直径よりも大きい径サイズを有し、軸部１３ｂが、重ね合わせたブラケット１１及びスペーサ１２のボルト穴１１ｂ，１２ｂから突出できるように当該ボルト穴１１ｂ，１２ｂの合計長さよりも長くなっている。   The temporary fixing bolt 13 has a head 13 a having a diameter larger than the diameter of the bolt hole 11 b of the bracket 11, and the shaft portion 13 b can protrude from the bolt holes 11 b, 12 b of the bracket 11 and the spacer 12 which are overlapped. Thus, it is longer than the total length of the bolt holes 11b and 12b.

このような本実施形態に係る仮固定治具１０を使用する回転電機であるエレベータの巻上機のモータの組立方法を図４〜６に基づいて説明する。   A method of assembling a motor of an elevator hoist, which is a rotating electric machine, using the temporary fixing jig 10 according to the present embodiment will be described with reference to FIGS.

まず、工場において、環状をなすステータ１１２を内周面に同軸をなして取り付けた円筒形のフレーム１１１の一端側（図４Ａ中、紙面手前側、図４Ｂ中、左端側）に、複数（本実施形態では３つ）のブラケット１１の基端側を周方向に沿って規定間隔（本実施形態では等間隔）でそれぞれ配設して、ボルト穴１１ｃに取付ボルト１４を各々差し込んで貫通させてフレーム１１１の一端側に螺合させ、当該ブラケット１１の基端側をフレーム１１１にそれぞれ取り付ける。   First, at a factory, a plurality of (frames) are attached to one end of the cylindrical frame 111 having the annular stator 112 coaxially attached to the inner peripheral surface thereof (in FIG. 4A, the front side of the paper, and FIG. 4B, the left end side). The base ends of the (three in the embodiment) brackets 11 are disposed at regular intervals (equal intervals in the present embodiment) along the circumferential direction, and the mounting bolts 14 are inserted into the bolt holes 11c and penetrated. The bracket 11 is screwed to one end of the frame 111, and the base end of the bracket 11 is attached to the frame 111.

そして、環状をなすロータ１１３をステータ１１２の内部に配設して、ブラケット１１のボルト穴１１ｂにスペーサ１２のボルト穴１２ｂを各々連絡させるようにブラケット１１の台座部１１ａにスペーサ１２をそれぞれ配置して上記ボルト穴１１ｂ，１２ｂに仮固定ボルト１３を差し込んで貫通させてロータ１１３の仮固定台座部１１３ａにそれぞれ螺合させる。   The annular rotor 113 is disposed inside the stator 112, and the spacers 12 are arranged on the pedestal portion 11a of the bracket 11 so that the bolt holes 11b of the bracket 11 are connected to the bolt holes 12b of the spacer 12, respectively. Then, the temporary fixing bolts 13 are inserted into the bolt holes 11b and 12b and penetrated to be screwed into the temporary fixing pedestals 113a of the rotor 113, respectively.

このようにして、ロータ１１３は、ステータ１１２と同軸をなすように仮固定治具１０でフレーム１１１に仮固定される。   In this manner, the rotor 113 is temporarily fixed to the frame 111 by the temporary fixing jig 10 so as to be coaxial with the stator 112.

そして、フレーム１１１に対してロータ１１３を仮固定したら、現場にまで搬送し、網車の回転軸１１４をロータ１１３の内部に挿入してロータ１１３に回転軸１１４を装着した後、仮固定ボルト１３をそれぞれ外してブラケット１１の台座部１１ａとロータ１１３の仮固定台座部１１３ａとの間からスペーサ１２を各々取り外す（図５参照）。   When the rotor 113 is temporarily fixed to the frame 111, the rotor 113 is transported to the site, the rotating shaft 114 of the mesh wheel is inserted into the rotor 113, the rotating shaft 114 is mounted on the rotor 113, and the temporarily fixed bolts 13 are fixed. And the spacers 12 are respectively removed from between the pedestal portion 11a of the bracket 11 and the temporary fixed pedestal portion 113a of the rotor 113 (see FIG. 5).

このようにして、ロータ１１３は、ステータ１１２と同軸をなすように回転軸１１４に本固定される。   In this way, the rotor 113 is permanently fixed to the rotating shaft 114 so as to be coaxial with the stator 112.

そして、フレーム１１１の内側と外側とを仕切るように覆う円板形のカバー１１５を当該フレーム１１１の一端側に同軸をなして配設し、当該カバー１１５を取付ボルト１１６でブラケット１１及びフレーム１１１に取り付けることにより（図６参照）、エレベータの巻上機のモータ１１０が現場で組み立てられて据え付けられる。なお、図６中、１１５ａはカバー１１５とフレーム１１１との間の空隙を塞ぐ台座部である。   Then, a disk-shaped cover 115 that covers the inside and outside of the frame 111 is disposed coaxially on one end side of the frame 111, and the cover 115 is attached to the bracket 11 and the frame 111 with mounting bolts 116. By mounting (see FIG. 6), the elevator hoist motor 110 is assembled and installed on site. In FIG. 6, reference numeral 115a denotes a pedestal portion that closes a gap between the cover 115 and the frame 111.

つまり、従来は、環状をなす大型で重量物の仮固定治具によってロータをフレームに対して仮固定して、当該仮固定治具を取り外すことによって仮固定を解除すると共にカバーをフレームに装着できるようにしていたが、本実施形態においては、複数（本実施形態では３つ）の板状をなす小型で軽量のブラケット１１及びスペーサ１２によってロータ１１３を仮固定して、スペーサ１２を取り外すことによって仮固定を解除すると共にフレーム１１１にブラケット１１を取り付けたままカバー１１５を装着ことができるようにしたのである。   That is, conventionally, the rotor is temporarily fixed to the frame by a large-sized and heavy temporary fixing jig, and the temporary fixing is released by removing the temporary fixing jig, and the cover can be attached to the frame. However, in this embodiment, the rotor 113 is temporarily fixed by a plurality of (three in this embodiment) plate-shaped small and lightweight brackets 11 and spacers 12, and the spacers 12 are removed. The temporary fixing is released, and the cover 115 can be attached with the bracket 11 attached to the frame 111.

このため、従来は、取り付けや取り外し等の作業に多大な労力を要してしまっていたものの、本実施形態においては、取り付けや取り外し等の作業を非常に容易に行うことが可能となる。   For this reason, although a great deal of labor has conventionally been required for operations such as attachment and detachment, operations such as attachment and detachment can be performed very easily in the present embodiment.

したがって、本実施形態に係る仮固定治具１０及びこれを使用するエレベータの巻上機のモータ１１０の組立方法よれば、作業性を大幅に向上させることができる。   Therefore, according to the temporary fixing jig 10 according to the present embodiment and the method of assembling the motor 110 of the elevator hoist using the same, the workability can be greatly improved.

〈第二番目の実施形態〉
本発明に係る回転電機の仮固定治具及びこれを使用する回転電機の組立方法の第二番目の実施形態を図７〜９に基づいて説明する。なお、前述した実施形態と同様な部分については、前述した実施形態の説明で用いた符号と同様な符号を用いることにより、前述した実施形態での説明と重複する説明を省略する。 <Second embodiment>
Second Embodiment A temporary fixing jig for a rotating electric machine according to the present invention and a method for assembling a rotating electric machine using the same will be described with reference to FIGS. In addition, about the same part as the above-mentioned embodiment, the same code | symbol as the code | symbol used in description of the above-mentioned embodiment is used, and the overlapping description with the above-mentioned embodiment is omitted.

本実施形態は、前述した実施形態と同一の回転電機の仮固定治具１０である。   This embodiment is a temporary fixing jig 10 of the same rotating electric machine as the above-described embodiment.

このような仮固定治具１０を使用する本実施形態に係るエレベータの巻上機のモータの組立方法を次に説明する。   Next, a method of assembling the motor of the elevator hoist according to the present embodiment using the temporary fixing jig 10 will be described.

前述した実施形態の場合と同様に、工場において、ステータ１１２と同軸をなすようにロータ１１３をフレーム１１１に仮固定治具１０で仮固定したら、そのまま引き続き、フレーム１１１の内側と外側とを仕切るように覆うと共に仮固定ボルト１３の頭部１３ａを露出させる露出穴１１５ｂを形成されてフレーム１１１の内側と外側とを連通させる作業穴１１５ｃを蓋板１１５ｄで開閉可能に塞がれた円板形のカバー１１５を当該フレーム１１１の一端側に同軸をなして配設し、当該カバー１１５を取付ボルト１１６でブラケット１１及びフレーム１１１に取り付ける（図７参照）。   As in the case of the above-described embodiment, when the rotor 113 is temporarily fixed to the frame 111 by the temporary fixing jig 10 so as to be coaxial with the stator 112 at the factory, the inside and outside of the frame 111 are continuously partitioned. And a work hole 115c for communicating the inside and the outside of the frame 111 with a cover plate 115d so as to be openable and closable. The cover 115 is disposed coaxially on one end side of the frame 111, and the cover 115 is attached to the bracket 11 and the frame 111 with attachment bolts 116 (see FIG. 7).

このようにしてフレーム１１１にカバー１１５を取り付けたら、現場にまで搬送し、網車の回転軸１１４をロータ１１３の内部に挿入してロータ１１３に回転軸１１４を装着し、カバー１１５の蓋板１１５ｄを開けて作業穴１１５ｃを開放し、前述した実施形態の場合と同様に、仮固定ボルト１３をそれぞれ外してブラケット１１の台座部１１ａとロータ１１３の仮固定台座部１１３ａとの間からスペーサ１２を各々取り外してカバー１１５の作業穴１１５ｃから外部へ搬出した後（図８参照）、カバー１１５の蓋板１１５ｄを閉じて作業穴１１５ｃを閉塞すると共にブラケット１１のボルト穴１１ｂを栓部材１５で塞ぐことにより（図９参照）、エレベータの巻上機のモータ１１０を現場で組み立てて据え付けることができる。   After the cover 115 is attached to the frame 111 in this manner, the frame is transported to the site, the rotating shaft 114 of the mesh wheel is inserted into the rotor 113, the rotating shaft 114 is mounted on the rotor 113, and the cover plate 115d of the cover 115 , The working hole 115c is opened, and the temporary fixing bolts 13 are respectively removed to separate the spacer 12 from between the pedestal portion 11a of the bracket 11 and the temporary fixing pedestal portion 113a of the rotor 113, as in the above-described embodiment. After each of them is removed and taken out from the work hole 115c of the cover 115 to the outside (see FIG. 8), the cover plate 115d of the cover 115 is closed to close the work hole 115c, and the bolt hole 11b of the bracket 11 is closed by the plug member 15. (See FIG. 9), the motor 110 of the elevator hoist can be assembled and installed on site.

つまり、前述した実施形態においては、現場において、ロータ１１３を回転軸１１４に本固定してから、フレーム１１１にカバー１１５を取り付けるようにしたが、本実施形態においては、工場において、ロータ１１３をフレーム１１１に仮固定したら、そのまま引き続いて、フレーム１１１にカバー１１５を取り付けた後に、現場にまで搬送するようにしたのである。   That is, in the above-described embodiment, the rotor 113 is fixed to the rotating shaft 114 at the site, and then the cover 115 is attached to the frame 111. In the present embodiment, the rotor 113 is After being temporarily fixed to the frame 111, the cover 115 is attached to the frame 111 and then transported to the site.

このため、前述した実施形態では、カバー１１５を現場まで別個に搬送しなければならなかったものの、本実施形態においては、カバー１１５を現場まで一体的に搬送することができる。   Therefore, in the above-described embodiment, the cover 115 has to be separately transported to the site, but in the present embodiment, the cover 115 can be transported integrally to the site.

したがって、本実施形態によれば、前述した実施形態の場合と同様な効果を得ることができるのはもちろんのこと、作業効率をさらに向上させることができる。   Therefore, according to the present embodiment, it is possible to obtain not only the same effects as in the above-described embodiment, but also to further improve the working efficiency.

〈他の実施形態〉
