【考案の詳細な説明】
この考案は水中形電動機のスラスト軸受装置、とくにス
ラスト受に関するものである。[Detailed Description of the Invention] This invention relates to a thrust bearing device for a submersible electric motor, and in particular to a thrust bearing.
従来の水中形電動機のスラスト受の材質としては、一般
に金属を使用することが多く、相手材のスラスト円板に
はカーボンや合成樹脂を用いていた。Conventional submersible electric motors typically use metal as the material for their thrust bearings, and carbon or synthetic resin is used for the mating thrust disk.
しかし、これらの材料の組合せにおいては、水潤滑とい
う苛酷な条件のために、スラスト荷重が増加するにつれ
て、焼付や異常摩耗が発生するという欠点があった。However, the combination of these materials has the disadvantage that seizure and abnormal wear occur as the thrust load increases due to the severe conditions of water lubrication.
この考案は従来の欠点を除去するためになされたもので
、以下図示実施例により説明する。This invention was devised to eliminate the drawbacks of the prior art, and will be explained below with reference to the illustrated embodiments.
図中、1はスラスト軸受支え、2はイコライザー、3は
ピン、4はスラスト受台座、5はスラスト受、6はスラ
スト円板、Tは回転機の軸である。In the figure, 1 is a thrust bearing support, 2 is an equalizer, 3 is a pin, 4 is a thrust bearing pedestal, 5 is a thrust receiver, 6 is a thrust disk, and T is a shaft of a rotating machine.
スラスト受5は、アスベストを繊維状に経ったもので布
織り、その布状のシートを所要枚数積層したものに樹脂
を含浸させ、加熱圧縮により成型したものを第2図に示
すように繊維状の網目が表面に見えるように、すなわち
この成型品の布状部分がスラスト円板6との摺動向とな
るようにスラスト受台座4に接着またはねじ止め等によ
り一体化されている。The thrust receiver 5 is made of fibrous asbestos, which is woven into a cloth, and the required number of cloth-like sheets are laminated, impregnated with resin, and molded by heating and compression. It is integrated with the thrust receiving pedestal 4 by gluing or screwing so that the mesh is visible on the surface, that is, the cloth-like portion of this molded product slides against the thrust disk 6.
また相手摺動材のスラスト円板6としては、耐食性のあ
る金属材料、たとえば銅合金あるいはステンレス鋼など
を使用すればよい。Further, as the thrust disk 6 of the mating sliding member, a corrosion-resistant metal material such as a copper alloy or stainless steel may be used.
この考案装置によれば、スラスト受がシート状に織り合
わせた構造になっているためある程度の吸水性を有する
ことになり、このスラスト受に含まれた水により、運転
中にスラスト受とスラスト円板との摺動面から完全に潤
滑水がなくならず、軸受の焼付や異常摩耗を防ぐことが
できる。According to this devised device, since the thrust receiver has a sheet-like interwoven structure, it has a certain degree of water absorption. Lubricating water does not completely disappear from the sliding surface with the plate, preventing seizure and abnormal wear of the bearing.
また、上述の摺動向の加工精度が悪い場合、従来装置で
は直ちに潤滑不能になり焼付、異常摩耗を起こしていた
が、本考案の装置ではスラスト受に含まれた水により潤
滑され徐々に摺動向がなじみ、安定してくるので、従来
より底い精度の加工でも高苛重を受けることができる軸
受となる効果がある。In addition, if the machining precision of the sliding movement described above is poor, the conventional equipment would immediately become unable to lubricate, resulting in seizure and abnormal wear, but with the device of the present invention, the water contained in the thrust receiver lubricates the sliding movement and gradually moves the sliding movement. As the bearing becomes more stable and stable, it has the effect of making the bearing able to withstand higher loads even during machining with lower precision than conventional bearings.
