A bolt hole 31b is formed through which the combined bolt 33 is inserted and penetrated (in FIG. 1A, in the vertical direction of the paper surface, in FIG. 1B, in the left-right direction), and is on the tip side of the bolt hole 31b (in FIGS. 1A and 1B). , Lower side) is formed with a female screw hole 31c through which the combined bolt 33 is screwed in the thickness direction (in FIG. 1A, vertical direction on the paper surface, in FIG. 1B, left-right direction), and further, the base end side (in the base end side). A bolt hole 31d is formed on the upper side in FIG. 1) through which the mounting bolt 34 is inserted and penetrated in the thickness direction.

スペーサ３２は、直方体形状をなし、ブラケット３１のボルト穴３１ｂ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）へ兼用ボルト３３を差し込まれて貫通させるボルト穴３２ｂが形成されている。 The spacer 32 has a rectangular cuboid shape, and is a bolt hole that communicates with the bolt hole 31b of the bracket 31 and allows the combined bolt 33 to be inserted and penetrated in the thickness direction (in FIG. 2A, in the vertical direction on the paper surface, in FIG. 2B, in the left-right direction). 32b is formed.

兼用ボルト３３は、頭部３３ａが、ブラケット３１のボルト穴３１ｂ及びめねじ穴３１ｃの直径よりも大きい径サイズを有し、軸部３３ｂが、重ね合わせたブラケット３１及びスペーサ３２のボルト穴３１ｂ，３２ｂから突出できるように当該ボルト穴３１ｂ，３２ｂの合計長さよりも長くなっている。 In the combined bolt 33, the head 33a has a diameter size larger than the diameter of the bolt hole 31b and the female screw hole 31c of the bracket 31, and the shaft portion 33b has the bolt hole 31b of the bracket 31 and the spacer 32 overlapped with each other. It is longer than the total length of the bolt holes 31b and 32b so that it can protrude from 32b.

このような本実施形態に係る仮固定治具３０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４～７に基づいて説明する。 A method of assembling the motor of the elevator hoist, which is a rotary electric machine using the temporary fixing jig 30 according to the present embodiment, will be described with reference to FIGS. 4 to 7.

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３１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３１ｄに取付ボルト３４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３１の基端側をフレーム１１１にそれぞれ取り付ける。 First, in a factory, a plurality (this The base end sides of the brackets 31 (three in the embodiment) are arranged at predetermined intervals (equally spaced in the present embodiment) along the circumferential direction, and the mounting bolts 34 are inserted into the bolt holes 31d and penetrated. It is screwed to one end side of the frame 111, and the base end side of the bracket 31 is attached to the frame 111, respectively.

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３１のボルト穴３１ｂにスペーサ３２のボルト穴３２ｂを各々連絡させるようにブラケット３１の台座部３１ａにスペーサ３２をそれぞれ配置して上記ボルト穴３１ｂ，３２ｂに兼用ボルト３３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。 Then, the rotor 113 forming an annular shape is arranged inside the stator 112, and the spacer 32 is arranged in the pedestal portion 31a of the bracket 31 so that the bolt holes 32b of the spacer 32 are in contact with the bolt holes 31b of the bracket 31. The combined bolts 33 are inserted into the bolt holes 31b and 32b, penetrated, and screwed into the temporary fixing pedestal portion 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３０でフレーム１１１に仮固定される。 In this way, the rotor 113 is temporarily fixed to the frame 111 by the temporary fixing jig 30 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、兼用ボルト３３をそれぞれ外す（図５参照）。 Then, after temporarily fixing the rotor 113 to the frame 111, the rotor 113 is transported to the site, the rotating shaft 114 of the net wheel is inserted into the rotor 113, the rotating shaft 114 is attached to the rotor 113, and then the combined bolt 33 is attached. Remove each (see Fig. 5).

次に、外した兼用ボルト３３をブラケット３１のめねじ穴３１ｃに各々螺合させて、ブラケット３１の先端側とロータ１１３の仮固定台座部１１３ａとの間隔を拡げるように当該兼用ボルト３３の先端面をロータ１１３の仮固定台座部１１３ａにそれぞれ押し付ける（図６参照）。 Next, the removed combined bolt 33 is screwed into the female screw hole 31c of the bracket 31, and the tip of the combined bolt 33 is widened so as to widen the distance between the tip side of the bracket 31 and the temporary fixing pedestal portion 113a of the rotor 113. The surfaces are pressed against the temporary fixing pedestal portion 113a of the rotor 113 (see FIG. 6).

続いて、ブラケット３１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を各々取り外した後、兼用ボルト３３をブラケット３１のめねじ穴３１ｃから取り外すことにより、ロータ１１３がステータ１１２と同軸をなすように回転軸１１４に本固定される。 Subsequently, the spacer 12 is removed from between the pedestal portion 11a of the bracket 31 and the temporary fixing pedestal portion 113a of the rotor 113, and then the dual-purpose bolt 33 is removed from the female screw hole 31c of the bracket 31, so that the rotor 113 becomes a stator. It is finally fixed to the rotating shaft 114 so as to be coaxial with 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３１及びフレーム１１１に取り付けることにより（図７参照）、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。 Then, a disk-shaped cover 115 that covers the inside and the outside of the frame 111 is arranged coaxially on one end side of the frame 111, and the cover 115 is attached to the bracket 31 and the frame 111 with mounting bolts 116. By mounting (see FIG. 7), the motor 110 of the elevator hoist is assembled and installed in the field.

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３１及びスペーサ３２によってロータ１１３を仮固定して、スペーサ３２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３１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 can be temporarily fixed to the frame by a large and heavy temporary fixing jig forming an annular shape, and the temporary fixing can be released and the cover can be attached to the frame by removing the temporary fixing jig. However, in the present embodiment, the rotor 113 is temporarily fixed by a plurality of (three in the present embodiment) plate-shaped small and lightweight brackets 31 and spacers 32, and the spacers 32 are removed. The temporary fixing was released and the cover 115 could be attached with the bracket 31 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, conventionally, a great deal of labor has been required for the work of attaching and detaching, but in the present embodiment, the work of attaching and detaching can be performed very easily.

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 method of assembling the temporary fixing jig 10 and the motor 110 of the elevator hoist using the temporary fixing jig 10 according to the present embodiment, the workability can be significantly improved.

また、兼用ボルト３３をブラケット３１のめねじ穴３１ｃに各々螺合させて、兼用ボルト３３の先端面をロータ１１３の仮固定台座部１１３ａにそれぞれ押し付けることにより、ブラケット３１の先端側とロータ１１３の仮固定台座部１１３ａとの間隔を拡げるようにしたことから、ブラケット３１の台座部１１ａとロータ１１３の仮固定台座部１１３ａとで間にスペーサ１２を強く挟持してしまっていたとしても、当該間からスペーサ１２を取り外すことが容易にできる。 Further, by screwing the combined bolt 33 into the female screw hole 31c of the bracket 31 and pressing the tip surface of the combined bolt 33 against the temporary fixing pedestal portion 113a of the rotor 113, the tip side of the bracket 31 and the rotor 113 are respectively. Since the distance from the temporary fixing pedestal portion 113a is widened, even if the spacer 12 is strongly sandwiched between the pedestal portion 11a of the bracket 31 and the temporary fixing pedestal portion 113a of the rotor 113, the space between them is the same. The spacer 12 can be easily removed from the space.

〈他の実施形態〉
なお、前述した実施形態においては、ブラケット３１及びスペーサ３２のボルト穴３１ｂ，３２ｂを貫通してロータ１１３の仮固定台座１１３ａに着脱可能に螺合する仮固定ボルトと、ブラケット３１を貫通するようにブラケット３１のめねじ穴３１ｃに螺合してロータ１１３の仮固定台座１１３ａに先端面を押し付け可能な押付ボルトとを兼用ボルト３３によって同一部材とするようにしたが、他の実施形態として、仮固定ボルトと押付ボルトとをそれぞれ異なる部材とすることも可能である。 <Other embodiments>
In the above-described embodiment, the temporary fixing bolts that penetrate the bolt holes 31b and 32b of the bracket 31 and the spacer 32 and are detachably screwed to the temporary fixing pedestal 113a of the rotor 113 and the bracket 31 are penetrated. A pressing bolt that is screwed into the female screw hole 31c of the bracket 31 and can press the tip surface against the temporary fixing pedestal 113a of the rotor 113 is made the same member by the combined bolt 33. It is also possible to use different members for the fixing bolt and the pressing bolt.

しかしながら、前述した実施形態のように、仮固定ボルトと押付ボルトとを同一部材からなる兼用ボルト３３で構成するようにすれば、押付ボルトを別途用意する必要がなく、部品点数の増加を抑えることができるので、非常に好ましい。 However, if the temporary fixing bolt and the pressing bolt are composed of the combined bolt 33 made of the same member as in the above-described embodiment, it is not necessary to separately prepare the pressing bolt, and the increase in the number of parts can be suppressed. It is very preferable because it can be used.

また、前述した実施形態においては、エレベータの巻上機のモータに適用した場合について説明したが、本発明はこれに限らず、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であれば、前述した実施形態の場合と同様にして適用することができる。 Further, in the above-described embodiment, the case where the rotor is applied to the motor of the elevator hoist has been described, but the present invention is not limited to this, and the rotation for temporarily fixing the rotor to the cylindrical frame to which the stator is attached is not limited to this. If it is an electric machine, it can be applied in the same manner as in the case of the above-described embodiment.

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は、取り付けや取り外し等の作業性を大幅に向上させることができるので、産業上、極めて有益に利用することができる。 The temporary fixing jig for the rotary electric machine according to the present invention and the method for assembling the rotary electric machine using the jig can greatly improve workability such as attachment and detachment, and thus can be extremely beneficially used in industry. can.
