本考案はころがり軸受成立軸形電動機の下部軸受装置の
改良に関する。[Detailed Description of the Invention] The present invention relates to an improvement of a lower bearing device for a shaft-type electric motor with rolling bearings.
＝般にころがり軸受成立軸形電動機はポンプを駆動する
ものが多いが、この電動機とポンプを結合する継手は第
１図に示すような組合せをとっている。=In general, shaft-type electric motors with rolling bearings often drive pumps, and the joints that connect the electric motor and the pump are combined as shown in Figure 1.
すなわち第１図にかいて、電動機１は架台２の上に載シ
、ボルト等によシ固定されている。That is, in FIG. 1, an electric motor 1 is mounted on a frame 2 and fixed by bolts or the like.
電動機１の軸３とポンプの軸４とは各々継手５゜６によ
り直結され動力の伝達を行なっている。The shaft 3 of the electric motor 1 and the shaft 4 of the pump are directly connected through joints 5 and 6 to transmit power.
従来のころがり軸受成立軸形電動機の下部軸受装置は、
第２図に示す如く軸３、下部ころがり軸受７、下部ベア
リングブラケット８、外側油筒９、内側油動１０、締付
ナツト１１、油留筒１．２などによう構成されている。The conventional lower bearing device of a shaft-type electric motor with rolling bearings is
As shown in FIG. 2, it is composed of a shaft 3, a lower rolling bearing 7, a lower bearing bracket 8, an outer oil cylinder 9, an inner oil cylinder 10, a tightening nut 11, an oil reservoir cylinder 1.2, etc.
下部ベアリングブラケット８は電動機本体を支えており
その構造は一体の円環状になっている。The lower bearing bracket 8 supports the motor body and has an integral annular structure.
筐た第３図に示す如く回転子１３は上部ベアリングブラ
ケット１４に支えられ、この上部ベアリングブラケット
１４は固定子１５に固定されている。As shown in FIG. 3, the rotor 13 is supported by an upper bearing bracket 14, and the upper bearing bracket 14 is fixed to a stator 15.

！：マ徐々に吊り上げ、回転子１３の引抜きを行なって
いる。If the rotor 13 is to be pulled out from the stator 15 during inspection for a motor with such a structure, remove the bolts connecting the motor joint 5 and the pump joint 6 shown in Fig. Heat the shrink-fitted joint 5 on the motor side with a welding torch, heating coil, etc., and when the fit between the shaft 3 and the joint 5 loosens, remove the upper bearing bracket from the stator 15 as shown in Figure 3. The one that supported rotor 13 by 14! : The rotor 13 is being gradually lifted and pulled out.
その際外側油筒９、内側油動１０を固定しているボルド
はゆるめておく。At this time, loosen the bolts that secure the outer oil cylinder 9 and the inner oil cylinder 10.
上記のような方法で電動機の継手を軸より外す理由は、
継手５の外径が第２図に示す下部ベアリングブラケット
８の内径、つ１りころがり軸受の外径より大きく継手５
を取付けた１１では回転子１３の引抜きが不可能である
ためで、回転子１３を引抜く前に継手５を軸３よシ外す
ことは不可避の条件である。The reason for removing the motor joint from the shaft using the method described above is
The outer diameter of the joint 5 is larger than the inner diameter of the lower bearing bracket 8 shown in FIG.
This is because it is impossible to pull out the rotor 13 with the rotor 11 attached, and it is an unavoidable condition to remove the joint 5 from the shaft 3 before pulling out the rotor 13.
従って、軸３より継手５を外して回転子１３を引抜くに
は、第１図に示す架台２の内部が継手５を加熱する作業
が出来るように大きなスペースを取る必要がある。Therefore, in order to remove the joint 5 from the shaft 3 and pull out the rotor 13, it is necessary to take up a large space inside the frame 2 shown in FIG. 1 so that the joint 5 can be heated.
この作業するスペースをとるととカーない場合には、電
動機１を架台２より外してり −ン等で別の場所へ移動

いのであるが、このために電動機１を仮置きするスペー
スが必要となり非常に不経済である。If you do not have enough space to do this work, remove the motor 1 from the pedestal 2, move it to another location using a crane, etc., remove the joint 5, and remove the outer oil pipe 9 and the inner oil pipe. 10
It is possible to remove the bolts etc. fixing the rotor 13 and pull out the rotor 13, but this requires a space to temporarily store the electric motor 1, which is very uneconomical.
また、電動機が太きくなればなるほど設備や建屋も必然
的に大規模になう点検時間も大巾に増加し経済的に益々
不利となる。Furthermore, as the electric motor becomes thicker, the equipment and building will inevitably become larger and the inspection time will also increase significantly, making it even more economically disadvantageous.

形電動磯を提供することを目的とする。The present invention solves the uneconomical problems such as the increase in the scale of equipment and buildings and the increase in inspection time that occur when pulling out the rotor of a shaft-type electric motor with rolling bearings as described above, and makes it easy to pull out the rotor. The purpose of the present invention is to provide a rolling bearing type vertical shaft type electric rock having a structure that can be used.
以下本考案を第４図および第５図に示す一実施例によシ
説明する。The present invention will be explained below with reference to an embodiment shown in FIGS. 4 and 5.
第４図において、下部ベアリングブラケットはブラケッ

イドピン１８で位置決めでき、締付ボルト１９にて固定
されている。In FIG. 4, the lower bearing bracket is divided into a bracket body 16 and a bearing support 17, which can be positioned with guide pins 18 and fixed with tightening bolts 19.
ブラケット本体１６の内径は継手５の外径より大きく継

え１７、外側油動９、内側油動１０および油留筒１２の
重量はころがり軸受にて支える。The inner diameter of the bracket body 16 is larger than the outer diameter of the joint 5, so that the outer diameter of the joint 5 can be offset, and the weight of the bearing support 17, the outer oil drive 9, the inner oil drive 10, and the oil reservoir cylinder 12 is larger than the outer diameter of the joint 5. I will support you.
このような構造をもった電動機の回転子引抜き作業方法
は次の通うである。The method for removing the rotor of a motor with this structure is as follows.
すなわち、１ず電動機の継手５とポンプの継手６とを固
定しているボルトを外して直結を切り離す。That is, first, remove the bolts fixing the motor joint 5 and the pump joint 6 to disconnect the direct connection.
そして第４図に示すブラケット本体１６とベアリング支
え１７とを締付けているボルト１９を外す。Then, remove the bolts 19 that fasten the bracket body 16 and the bearing support 17 shown in FIG.
次に固定子１５に上部ベアリングブラケット１４を固定
しているボルト２０を外し案内用ピン２１をねじ込む。Next, the bolts 20 fixing the upper bearing bracket 14 to the stator 15 are removed, and the guide pins 21 are screwed in.
この状態で上部ベアリングブラケットを徐々に吊り上げ
ると回転子１３が上部軸受に支えられているため回転子
１３も徐々に吊り上げられる。When the upper bearing bracket is gradually lifted in this state, the rotor 13 is also gradually lifted because the rotor 13 is supported by the upper bearing.
その際継手５はブラケット本体１６、固定子鉄心２２、
防風板２３の各々の内径をかわして抜けて行く。At that time, the joint 5 includes the bracket main body 16, the stator core 22,
It bypasses the inner diameter of each of the windbreak plates 23 and passes through.
