On the other hand, a bolt hole 21c into which a mounting bolt is inserted in the thickness direction is formed on the base end side (upper side in FIG. 1).

スペーサ２２は、外周面にねじ山を形成された円柱形状のおねじ部２２ｄが六角形状の台座部２２ａの軸心上に軸心を位置させるように立設され、おねじ部２２ｄがブラケット２１のめねじ部２１ｄに螺合すると共に、ブラケット２１のボルト穴２１ｂと連通して仮固定ボルト２３を差し込まれるボルト穴２２ｂが台座部２２ａ及びおねじ部２２ｄの軸心上を貫通するようにして形成されている。   The spacer 22 is erected so that a cylindrical male screw portion 22d having a thread formed on the outer peripheral surface is positioned on the axis of the hexagonal pedestal portion 22a. The bolt holes 22b into which the temporary fixing bolts 23 are inserted in communication with the bolt holes 21b of the bracket 21 and which pass through the base 22a and the axial center of the male screw portion 22d are screwed into the female screw portions 21d.

Has become.

このような本実施形態に係る仮固定治具２０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 20 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）に対して、スペーサ２２のおねじ部２２ｄをめねじ部２１ｄに各々螺合させた複数（本実施形態では３つ）のブラケット２１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２１ｃに取付ボルト２４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２１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 spacer is attached to one end side (the front side in the drawing in FIG. 4A, the left end side in FIG. 4B) of the cylindrical frame 111 in which the annular stator 112 is coaxially mounted on the inner peripheral surface. Base ends of a plurality of (three in this embodiment) brackets 21 in which the 22 external thread portions 22d are respectively screwed into the female thread portions 21d are arranged at regular intervals (equal intervals in this embodiment) along the circumferential direction. The mounting bolts 24 are respectively inserted into the bolt holes 21 c and penetrated therethrough, screwed into one end of the frame 111, and the base end of the bracket 21 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、スペーサ２２の台座部２２ａをロータ１１３の仮固定台座部１１３ａにそれぞれ当接させるように、ブラケット２１のめねじ部２１ｄに対するスペーサ２２のおねじ部２２ｄの螺合位置を各々調整し、仮固定ボルト２３をブラケット２１のボルト穴２１ｂにそれぞれ差し込んでスペーサ２２のボルト穴２２ｂを経由して貫通させ、ロータ１１３の仮固定台座部１１３ａにそれぞれ螺合させる。   Then, the annular rotor 113 is disposed inside the stator 112, and the spacers for the female threads 21 d of the bracket 21 are arranged so that the pedestals 22 a of the spacer 22 abut against the temporarily fixed pedestals 113 a of the rotor 113, respectively. Each of the screw positions of the external thread portions 22d is adjusted, and the temporary fixing bolts 23 are respectively inserted into the bolt holes 21b of the bracket 21 and penetrated through the bolt holes 22b of the spacer 22, and the temporary fixing pedestal portion of the rotor 113 is 113a.

これにより、ロータ１１３は、ステータ１１２と同軸をなすように仮固定治具２０でフレーム１１１に仮固定される。   Thereby, the rotor 113 is temporarily fixed to the frame 111 by the temporary fixing jig 20 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２３をそれぞれ外すと共に、スペーサ２２の台座部２２ａをロータ１１３の仮固定台座部１１３ａからそれぞれ離反させるように、ブラケット２１のめねじ部２１ｄに対するスペーサ２２のおねじ部２２ｄの螺合位置を各々調整し、ブラケット２１の台座部２１ａにスペーサ２２の台座部２２ａをそれぞれ当接させる（図５参照）。   After 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, and the rotating shaft 114 is mounted on the rotor 113, And the screwing positions of the external threads 22d of the spacers 22 with respect to the internal threads 21d of the brackets 21 are adjusted so that the pedestals 22a of the spacers 22 are separated from the temporarily fixed pedestals 113a of the rotor 113, respectively. The pedestal portions 22a of the spacers 22 are respectively brought into contact with the pedestal portions 21a of the bracket 21 (see FIG. 5).

これにより、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。   As a result, 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２１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。   Then, a disk-shaped cover 115 that covers the inside and outside of the frame 111 is coaxially disposed on one end side of the frame 111, and the cover 115 is attached to the bracket 21 and the frame 111 with mounting bolts 116. By mounting (see FIG. 6), the elevator hoist motor 110 is assembled and installed on site.

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２１及びスペーサ２２によってロータ１１３を仮固定ボルト２３でフレーム１１１に仮固定し、仮固定ボルト２３を外してスペーサ２２をロータ１１３から離反させる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２１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 the present embodiment, the rotor 113 is temporarily fixed to the frame 111 with the temporary fixing bolts 23 by a plurality of (three in this embodiment) plate-like small and lightweight brackets 21 and spacers 22. By removing the temporary fixing bolt 23 and separating the spacer 22 from the rotor 113, the temporary fixing is released, and the cover 115 can be mounted with the bracket 21 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２０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 20 according to the present embodiment and the method of assembling the motor 110 of the elevator hoist using the temporary fixing jig 20, the workability can be greatly improved.

また、ブラケット２１に対するスペーサ２２の螺合位置を調整することにより、スペーサ２２をブラケット２１に保持させた状態でロータ１１３の仮固定台座部１１３ａに対して接近離反移動させることができるので、スペーサ２２とロータ１１３の仮固定台座部１１３ａとの間に隙間を簡単に形成することができると共に、仮固定ボルト２３を取り外したときに、スペーサ２２を誤って落下させてしまうことを防止することができ、スペーサ２２が他の部品に衝突して他の部品を傷付けてしまうことを未然に防止することができる。   In addition, by adjusting the screwing position of the spacer 22 with respect to the bracket 21, the rotor 22 can be moved toward and away from the temporary fixing base 113 a of the rotor 113 in a state where the spacer 22 is held by the bracket 21. A gap can be easily formed between the temporary fixing pedestal 113a of the rotor 113 and the temporary fixing bolt 23, and the spacer 22 can be prevented from being accidentally dropped when the temporary fixing bolt 23 is removed. In addition, it is possible to prevent the spacer 22 from hitting another component and damaging the other component.
