- the frictional force in the bearing portion 18 of the flange 16 and the engine 2 side is determined by the magnitude relationship with the frictional force at the spline engaging portion. For example, when the frictional force in the spline engaging portion on the engine 2 side is larger, the rotor side member 50 is left on the first housing 11 side. On the other hand, when the frictional force at the bearing portion 18 of the flange 16 is larger, the rotor side member 50 is removed together with the flange 16 and the rotary shaft 19.

- the locking portion 31 can be retracted from the locking groove 19c of the rotating shaft 19 like the locking member 30 arranged in the upper part of FIG. Accordingly, since the flange 16 is movable in the axial direction with respect to the rotating shaft 19, the locked state between the flange 16 and the rotor-side member 50 can be easily released.
- the locking portion 31 of the locking member 30 is rotated in the restriction groove portion 16b of the flange 16 shown in FIG. Switch between the stopped state.
- the state in which the side surface of the locking portion 31 of the locking member 30 is in contact with the first end surface 16ba of the V-shaped recess in the restriction groove portion 16b is the non-locking state, and the second end surface 16bb of the V-shaped recess.

- the rotor side member 50 can be removed in an integrated state. Therefore, the rotor side member 50 does not fall off from the fixed side after removing the flange 16 alone. As a result, it is possible to reliably prevent the rotor-side member 50 from falling off when the generator motor 1 is disassembled, and to prevent occurrence of breakage of components included in the rotor-side member 50.
- the locking member is inserted along the radial direction from the outer circumferential surface of the flange 116 in the radial direction, and reaches a locking groove 119 a formed on the outer circumferential surface of the rotating shaft 119. You may use the bolt member 130 which has these.

Abstract
Description
このようなハイブリッド型の建設機械に搭載された発電機モータは、エンジンの出力軸と油圧ポンプの入力軸とに接続されており、エンジンの駆動力によって発電を行う。そして、発電機モータでの発電により生じた電気エネルギーはキャパシタなどの蓄電装置に蓄えられ、建設機械が大きなエンジン出力を要する場合等に、蓄えられた電気エネルギーによって発電機モータが駆動されて、エンジンの出力を補助する。
すなわち、上記公報に開示された発電機モータでは、メンテナンスや故障時等に発電機モータを分解する必要が生じた場合には、通常、油圧ポンプ側から部品を取り外していく必要がある。このため、発電機モータを分解する際には、油圧ポンプを取り外した後、まず、油圧ポンプ側に配置されたフランジ部を取り外すことになる。
本発明の課題は、発電機モータを分解する際に、固定側からロータ側部材が脱落してしまうことを防止することが可能な発電機モータを提供することにある。
これにより、自由端側となる第1端部側においてフランジ部を取り外した場合でも、ロータ側部材もフランジ部と一緒に取り外すことができる。よって、フランジ部だけが取り外されて、ロータ側部材が固定側部材に対して軸方向に自由に移動可能な状態になることを回避できる。この結果、発電機モータの分解時において、固定側からのロータ側部材の脱落を確実に防止することができる。
ここでは、フランジ部とロータ側部材とを軸方向において一体化する係止部材を、フランジ部側に設けている。
これにより、発電機モータを分解する際にフランジ部を取り外した場合でも、フランジ部に設けられた係止部材を、ロータ側部材の一部に引っ掛けることで、フランジ部とロータ側部材とを一体化した状態で、第1端部側において取り外すことができる。
ここでは、フランジ部とロータ側部材との軸方向における相対移動を規制する係止部材を、ロータ側部材の回転中心となる回転軸の外周面近傍に設けている。
これにより、発電機モータを分解する際に、互いに一体化した状態で固定側部材から取り外したフランジ部とロータ側部材とを、係止部材を回動させるだけで、容易に分離することができる。
ここでは、回動可能な係止部材の回動範囲を、規制溝部によって規制している。
これにより、係止部材の一部が規制溝部の一方の端面に当接した状態において、ロータ側部材が固定側部材に対して係止された第1状態とし、規制溝部の反対側の端面に当接した状態において、ロータ側部材が固定側部材に対して開放された第2状態とすることができる。よって、係止部材を規制溝部の範囲内において回動させるだけで、上記第1状態と第2状態とを容易に切り換えることができる。
ここでは、係止部材として、略L字型の部材を用いている。
これにより、略L字型の係止部材の端部をロータ側部材側に形成された段差や溝等に引っ掛けるだけで、フランジ部とロータ側部材とを容易に一体化させることができる。
これにより、係止部材によってロータ側部材の回転が妨げられることはない。
これにより、発電機モータの分解時においてフランジ部を取り外した際には、ロータ側部材だけをフランジ部と一体化して取り外すことができる。
これにより、固定側部材にステータ等を残した状態で、回転軸やロータ等だけを容易に取り外すことができる。
なお、以下の説明において、軸方向、径方向、周方向とは、発電機モータ1に組み込まれた状態でのそれぞれの方向を意味している。具体的には、軸方向とは、発電機モータ1のロータ14の回転軸19の軸方向(図2における左右方向)を意味している。径方向とは、回転軸19を中心とする円の半径方向を意味している。周方向とは、回転軸19を中心とする円の円周方向を意味している。
本実施形態に係る発電機モータ1は、図1に示すように、エンジン2、冷却ファン3、油圧ポンプ4およびマフラー5等を備えたハイブリッド型の油圧ショベル(建設機械)に搭載されており、エンジン2と、油圧ポンプ4との間に配置されている。ハイブリッド型の油圧ショベルは、走行体と、走行体に旋回可能に設けられた旋回体とを備えている。旋回体は、作業機、キャブ、カウンタウエイト、エンジンルームを備えている。旋回体は、発電機モータ1あるいはキャパシタからの電気エネルギーにより動作する旋回電動モータにて駆動される。旋回電動モータは、旋回体の減速時に回生により発電し、発電で得られた電気エネルギーは、キャパシタに蓄電される。
第1ハウジング11は、鋳鉄製の部材であって、図3に示すように、第2ハウジング15と接合されて、内部にステータ10やロータ14等を収納する空間を形成する。そして、この収納空間の下部には、回転軸19や軸受け部18の潤滑を促すとともに、ステータ10の発熱部(コイル23等)を冷却するための冷却油を貯留する油溜めVが形成されている。また、第1ハウジング11の下端部には、図3に示すように、図2に示す油溜めVに連通する検油管(給油管と兼用)11aが接続されている。
貫通孔16cには、後述する係止部材30の回動軸32が挿入されて、ボルトおよびナット(図5参照)によって固定される。
中央孔16dは、円盤状のフランジ16の中央に設けられており、発電機モータ1を組み立てた状態において、回転軸19の油圧ポンプ4側の端部が挿入される。
本実施形態の発電機モータ1では、図4に示すように、フランジ16とロータ側部材50との間における軸方向における相対移動を規制するために、係止部材30を設けている。
本実施形態の発電機モータ1は、上述した構成を備えており、メンテナンス時や故障等の際には、エンジン2側(第2端部側)に第1ハウジング11等の固定側部材が固定された状態で、車体開口部に近い側である油圧ポンプ4側(第1端部側)から部品を取り外して分解される。
これにより、発電機モータ1の分解工程において、フランジ16を取り外した際に、第1ハウジング11等の固定側部材に対してロータ側部材50が軸方向に移動可能な状態で残されることを回避することができる。この結果、フランジ16だけを取り外した後、固定側に残されたロータ側部材50が不意に脱落してしまうことを防止して、ロータ側部材50に含まれる各部品の破損等を防止することができる。
これにより、係止部材30による係止状態と非係止状態との切り換えを確実かつ容易に実施することができる。
本実施形態の発電機モータ1では、図4に示すように、軸方向における油圧ポンプ4側において着脱されるフランジ16と、フランジ16を取り外した際に軸方向におけるエンジン2側に固定された固定側部材(第1・第2ハウジング11,15、ステータ10等)と、フランジ16を取り外した状態において固定側部材に対して軸方向における油圧ポンプ4側に移動可能なロータ側部材50と、フランジ16のロータ側部材50に対する軸方向における相対移動を規制する係止部材30と、を備えている。
以上、本発明の一実施形態について説明したが、本発明は上記実施形態に限定されるものではなく、発明の要旨を逸脱しない範囲で種々の変更が可能である。
上記実施形態では、フランジ16を取り外した際にロータ側部材50と一体化させるための係止部材30として、回動軸32を中心として回動可能な略L字型の部材を用いた例を挙げて説明した。しかし、本発明はこれに限定されるものではない。
