【産業上の利用分野】[Industrial applications]

この考案は、鉄道車両において、主電動機の駆動力を減速して車輪に伝達する 歯車装置における軸封装置の改良に関する。 The present invention relates to an improvement of a shaft sealing device in a gear device that decelerates a driving force of a main electric motor and transmits the driving force to wheels in a railway vehicle.

【0002】[0002]

【従来の技術】[Prior art]

鉄道車両における主電動機の駆動力を減速して車輪に伝達する歯車装置は、図 1に示すように、主電動機の電機子軸にたわみ継手を介して接続した小歯車軸5 に一体成形した小歯車2と、車軸4に取り付けた大歯車1を噛み合わせ歯車箱3 に納めてなり、歯車箱内に収容している潤滑油を大歯車1の回転によりかき上げ 、歯車噛み合い部および車軸4の両端に設けた軸受8と小歯車軸5の両端に設け た軸受9を潤滑する構造からなる。 As shown in FIG. 1, a gear device for reducing the driving force of a main electric motor in a railroad vehicle and transmitting it to wheels has a small gear shaft 5 integrally formed with a small gear shaft 5 connected to an armature shaft of the main electric motor via a flexible joint. The gear 2 and the large gear 1 attached to the axle 4 are meshed with each other and housed in the gear box 3. The lubricating oil contained in the gear box is scraped up by the rotation of the large gear 1, and the gear meshing portion and the axle 4 The bearing 8 provided at both ends and the bearing 9 provided at both ends of the pinion shaft 5 are lubricated.

【0003】 上記歯車装置の車軸4の車輪側に設けた軸封装置8は、図1および図3に示す ように、歯車箱3に取り付けた軸受押え10と車軸4に取り付けた油切り12に よりラビリンスが形成され、その外側にラビリンスシール13を形成した押え蓋 11を被着して構成されている。As shown in FIGS. 1 and 3, the shaft sealing device 8 provided on the wheel side of the axle 4 of the above gear device has a bearing retainer 10 attached to the gear box 3 and an oil drainer 12 attached to the axle 4. A labyrinth is further formed, and a pressing lid 11 having a labyrinth seal 13 formed thereon is attached to the outside thereof.

【0004】 上記歯車装置はラビリンスを設けて、車輪側に設けた軸受からの油漏れの防止 を図っている。その歯車装置を有する鉄道車両が高速走行すると、車輪6と歯車 箱3との隙間部分を通過する走行風等により負圧となり、歯車箱内において大歯 車によりかきあげられ軸受8を潤滑している油は、軸受押え10と油切り部材1 2との接触面すきま、ラビリンスシール13を経て外部へ吸引され油漏れが起こ る。The above gear device is provided with a labyrinth to prevent oil leakage from a bearing provided on the wheel side. When a railway vehicle having the gear device travels at high speed, a negative pressure is generated due to traveling wind passing through the gap between the wheel 6 and the gear box 3, and the bearing 8 is lubricated by being scraped up by the large gear in the gear box. Oil is sucked to the outside through the clearance between the bearing retainer 10 and the oil draining member 12 and the labyrinth seal 13 to cause oil leakage.

【0005】[0005]

【考案が解決しようとする課題】[Problems to be solved by the device]

上記のごとく、従来の鉄道車両用歯車装置は、高速走行時にラビリンスから油 漏れを起こす欠点があり、潤滑油の消耗が激しいばかりか、最良の潤滑状態を維 持するのが困難であつた。 As described above, the conventional railway vehicle gear device has the drawback of causing oil leakage from the labyrinth during high-speed traveling, which not only consumes the lubricating oil severely but also makes it difficult to maintain the optimum lubricating state.

【0006】 この考案は、上記の現状に鑑み、高速走行時にラビリンスから油漏れを防止す るため、歯車箱側に設けた軸受押え蓋に、車輪ボスとの間に密着シールを有する シール用押え部材からなる密封装置を提案するものである。In view of the above situation, this invention has a bearing retainer lid provided on the gear box side and a seal retainer provided with a close contact seal with the wheel boss in order to prevent oil leakage from the labyrinth during high-speed traveling. It proposes a sealing device composed of members.

【0007】[0007]

【課題を解決するための手段】[Means for Solving the Problems]

上記目的を達成するため、この考案の鉄道車両用歯車装置の密封装置は、主電 動機の電機子軸にたわみ継手を介して接続した小歯車軸に一体成形した小歯車と 、車軸に取り付けた大歯車を噛み合わせ歯車箱に納めた歯車装置において、車軸 の車輪側を軸支する軸受の押え蓋に、車輪ボスとの間に密封シールを有するシー ル用押え部材を設けてなる。 In order to achieve the above object, a sealing device for a gear device for a railway vehicle according to the present invention is attached to an axle and a small gear integrally formed with a small gear shaft connected to an armature shaft of a main motor through a flexible joint. In a gear device in which a large gear is meshed in a gear box, a seal cover member having a hermetic seal is provided between a wheel boss and a cover of a bearing that supports the wheel side of an axle.

【0008】[0008]

【作用】[Action]

軸受の押え蓋と車輪ボスとの間は、密封シールを有するシール用押え部材で塞 がれているため、鉄道車両の高速走行に伴い走行風が生じても、軸受側にその影 響を及ぼすことはない。その結果、軸受側からの潤滑油の油漏れが防止できる。 Since the bearing retainer lid and the wheel boss are closed by a seal retainer member that has a hermetic seal, even if a running wind is generated as the railway vehicle travels at high speed, it will affect the bearing side. There is no such thing. As a result, it is possible to prevent the lubricating oil from leaking from the bearing side.

【0009】 上記のごとく、ラビリンスからの油漏れが阻止される結果、潤滑油のむだな消 耗が減少し、最良の潤滑状態を維持できる。As described above, as a result of preventing oil leakage from the labyrinth, wasteful consumption of lubricating oil is reduced, and the best lubrication state can be maintained.

Seal presser having a close seal 14 between the wheel boss 7 and the wheel boss 7. Providing an sealing device comprising a timber 15, to seal between the sealing pressing member 15 and the drive wheel hub 7 in close contact with the seal 14.

【0011】 上記密着シール14により軸受内部と、歯車箱3と車輪6間の隙間は完全に遮 断され、ラビリンスからの油漏れを防止できる。なお、密着シール14が密着す ることにより車輪ボス側が磨耗するが、その磨耗量は車輪の取替え時期までは使 用に差し支えない程度のものであり、車輪の使用寿命を低下させることはない。The contact seal 14 completely blocks the inside of the bearing and the gap between the gear box 3 and the wheel 6, thereby preventing oil leakage from the labyrinth. Although the wheel boss side is worn due to the close contact of the close contact seal 14, the wear amount is such that it can be used until the time when the wheel is replaced, and it does not reduce the service life of the wheel.
