本考案は機械装置の潤滑油のフィルター装置に関し、特にギア機構を備えた機 械装置の潤滑に供される潤滑油中の異物を効率良く除去し得る小型且つ簡単な構 成の機械装置の潤滑油のフィルター装置に関する。 The present invention relates to a lubricating oil filter device for a mechanical device, and more particularly to a lubricating device for a mechanical device having a gear mechanism, which is capable of efficiently removing foreign matters contained in the lubricating oil and having a small and simple structure. The present invention relates to an oil filter device.

例えば、車両の変速機や差動装置などギア機構を備えた機械装置においては、 ギア機構を収容するケーシングの下部に潤滑油を貯溜するための油溜室が設けら れ、油溜室の潤滑油は、ギア機構の作動により或いはポンプを作動させることに よりギア機構の噛合部や摺動部など潤滑を要する機械装置の各部に供給され、そ れらを潤滑した後油溜室に回収されるようになっている。 前記機械装置の各部には組立加工時に発生した切粉などが付着しており、また 機械装置の作動時にはギア機構の噛合部や摺動部などから金属摩耗粒子が発生し 、これら異物が混入した潤滑油を繰り返して機械装置の各部に供給すると、機械 装置の摩耗が助長されたり、機械装置の故障を招く原因となるため、従来より、 潤滑油中の異物を除去する為のフィルター装置が種々提案され実用化されている 。 例えば、実公昭６３−１９６８０号公報には、変速機のケーシングの一方の側 壁部のうちギア機構の噛合部に略対向する部分に開口部を形成し、この開口部を 介してフィルター部材を収容した箱状のフィルター装置をケーシング内側に突出 するように配設し、ギア機構のギアの回転により油溜室から掻き上げられて落下 する潤滑油がフィルター装置を通過することにより、潤滑油中の異物を除去する ようにしたフィルター装置が記載されている。 For example, in a mechanical device having a gear mechanism such as a transmission and a differential gear of a vehicle, an oil storage chamber for storing lubricating oil is provided at the bottom of a casing that houses the gear mechanism, and the oil storage chamber is lubricated. The oil is supplied to each part of the mechanical device that requires lubrication, such as the meshing parts and sliding parts of the gear mechanism, by operating the gear mechanism or by operating the pump, and after lubricating them, they are collected in the oil sump chamber. It has become so. Chips generated during assembly work adhere to each part of the mechanical device, and metal wear particles are generated from the meshing parts and sliding parts of the gear mechanism when the mechanical device operates, and these foreign substances are mixed in. Repeated supply of lubricating oil to each part of the mechanical device may promote wear of the mechanical device or cause failure of the mechanical device.Therefore, various filter devices have been used to remove foreign matter in the lubricating oil. Proposed and put to practical use. For example, in Japanese Utility Model Publication No. 63-19680, an opening is formed in a portion of one side wall of a transmission casing that substantially faces a meshing portion of a gear mechanism, and a filter member is provided through this opening. The box-shaped filter device that has been housed is arranged so as to project inside the casing, and the lubricating oil that is scraped up and dropped from the oil storage chamber by the rotation of the gears of the gear mechanism passes through the filter device, so that It describes a filter device that is designed to remove foreign matter.

前記公報に記載のフィルター装置においては、ケーシングの側壁部の一部分に だけフィルター装置が設けられているため、異物除去能力が小さくて目詰りを生 じやすく、フィルター部材の交換又は洗浄など頻繁にフィルター装置のメインテ ナンスを行わなければならないという問題がある。また、油溜室に向って落下す る潤滑油の一部しかフィルター装置を通過しないため、異物除去効率が著しく低 いという問題がある。更に、ケーシングの側壁部に開口部を形成してフィルター 装置を配設するため、ケーシングの強度・剛性が低下するという問題がある。加 えて、箱状のフィルター装置をケーシングの内側に突出状に設けるには、ケーシ ング内のスペース上の制約からケーシングを大型化しなければならないとう問題 がある。 In the filter device described in the above publication, since the filter device is provided only on a part of the side wall of the casing, the foreign matter removing ability is small and clogging is likely to occur, and the filter member is frequently replaced such as when replacing or cleaning the filter member. There is a problem that maintenance of the device must be performed. In addition, since only part of the lubricating oil that drops toward the oil reservoir passes through the filter device, there is a problem that the foreign matter removal efficiency is extremely low. Further, since the opening is formed in the side wall portion of the casing and the filter device is disposed, there is a problem that the strength and rigidity of the casing are lowered. In addition, in order to provide the box-shaped filter device so as to project inside the casing, there is a problem that the casing must be upsized due to the space limitation in the casing.
【０００４】 本考案の目的は、潤滑油中の異物を効率良く除去し得る小型且つ簡単な構成の 機械装置の潤滑油のフィルター装置を提供することである。An object of the present invention is to provide a lubricating oil filter device of a mechanical device having a small size and a simple structure capable of efficiently removing foreign matters in the lubricating oil.

【００１１】 次に、前記のように構成されたフィルター装置ＦＳの作用について説明する。 変速機ＴＭが作動すると、前述のように潤滑の必要な部位に潤滑油１１が供給 されるとともに、潤滑に供された潤滑油１１の殆どは、図４に示すように、ギヤ ２〜６や各軸７〜９の回転による遠心力によりケーシング１の内壁部１ａ側に向 かって飛散し、その後内壁部１ａを伝わって落下する。内壁部１ａを落下する潤 滑油１１は全て油受けリブ１５で受け止められ、その後、図２に矢印で示したよ うに、前後のフィルター部材２０側に流れ出す。 変速機ＴＭが故障しかかっているときなどには、ギア２〜６の噛合部や各軸７ 〜９などの偏摩耗などに起因する粒径約２０μｍ以上の大きな摩耗粒子が発生し 、この摩耗粒子は通常摩耗により発生する粒径約１０μｍの大きさ摩耗粒子とと もに潤滑油１１に混入するが、潤滑油１１が油受けリブ１５に受け止められ油受 けリブ１５に沿って流れる途中において、潤滑油１１中の大きな摩耗粒子は底壁 部１５ａに沈殿して滞留する。一方、潤滑油１１中の小さな摩耗粒子はフィルタ ー部材２０のフィルター２２により除去され、摩耗粒子が除去されて浄化された 潤滑油１１は開口部１５ｂから下方の油溜室１２に落下して回収される。Next, the operation of the filter device FS configured as described above will be described. When the transmission TM operates, the lubricating oil 11 is supplied to the portion requiring lubrication as described above, and most of the lubricating oil 11 that has been lubricated is, as shown in FIG. The centrifugal force generated by the rotation of the shafts 7 to 9 scatters toward the inner wall portion 1a of the casing 1 and then falls along the inner wall portion 1a. All of the lubricating oil 11 that falls on the inner wall portion 1a is received by the oil receiving ribs 15, and then flows out to the front and rear filter member 20 sides as indicated by the arrows in FIG. When the transmission TM is about to fail, large wear particles having a particle size of about 20 μm or more are generated due to uneven wear of the meshing parts of the gears 2 to 6 and the shafts 7 to 9, and the like. Is mixed with the lubricating oil 11 together with the wear particles having a particle size of about 10 μm, which is usually generated by abrasion, but while the lubricating oil 11 is received by the oil receiving rib 15 and flows along the oil receiving rib 15, Large wear particles in the lubricating oil 11 settle and stay in the bottom wall portion 15a. On the other hand, the small wear particles in the lubricating oil 11 are removed by the filter 22 of the filter member 20, and the cleaned and cleaned lubricating oil 11 is dropped from the opening 15b into the oil reservoir 12 below and collected. To be done.
【００１２】 変速機ＴＭの定期点検時などに点検用窓部材２７からフィルター２２の前記摩 耗粒子などを含む異物の蓄積状態が点検され、フィルター２２が機能しないほど 異物が蓄積している場合には、フィルター部材２０をケーシング１から取り外し てフィルター２２の洗浄を行う。フィルター部材２０は、ナット部材２６をネジ 部材２５から取り外した後左方に引き抜くことにより簡単に取り外される。また 、油受けリブ１５に滞留した異物は定期点検時又は必要に応じて除去する。 このように、油受けリブ１５をケーシング１の内壁部１ａの中段部の全周に形 成することにより、潤滑油１１に混入した大きな異物は油受けリブ１５により除 去され、小さな異物だけがフィルター２２により除去されるので、フィルター２ ２が短期間に目詰まりすることはなく、フィルター２２を頻繁に洗浄したり交換 する必要もなくなるので、フィルター装置ＦＳのメインテナンス性が著しく高め られる。また、変速機ＴＭの潤滑に供せられた潤滑油１１は殆ど油受けリブ１５ に受け止められて異物を除去されるので、フィルター装置ＦＳの異物の除去効率 を大幅に高めることが出来る。更に、油受けリブ１５はケーシングを補強する為 のリブとしてケーシング１と一体に小型に形成されるので、ケーシング１の強度 ・剛性を高めることが出来るうえフィルター装置ＦＳを小型且つ簡単に構成出来 る。 尚、前記フィルター装置ＦＳは、変速機ＴＭ以外にエンジン、ディフェレンシ ャル装置、或いはギア機構を備えた種々の加工機械などに適用出来ることは勿論 である。When the accumulated state of foreign matter including the wear particles of the filter 22 is inspected from the inspection window member 27 at the time of periodic inspection of the transmission TM, and the foreign matter is accumulated so that the filter 22 does not function. Cleans the filter 22 by removing the filter member 20 from the casing 1. The filter member 20 is easily removed by removing the nut member 26 from the screw member 25 and then pulling it out to the left. Further, the foreign matter staying on the oil receiving rib 15 is removed at the time of regular inspection or when necessary. By forming the oil receiving ribs 15 on the entire circumference of the middle part of the inner wall portion 1a of the casing 1 in this manner, large foreign matters mixed in the lubricating oil 11 are removed by the oil receiving ribs 15, and only small foreign matters are formed. Since the filter 22 is removed by the filter 22, the filter 22 is not clogged in a short period of time, and the filter 22 does not need to be frequently washed or replaced, so that the maintainability of the filter device FS is significantly enhanced. Further, most of the lubricating oil 11 used for lubricating the transmission TM is received by the oil receiving ribs 15 to remove foreign matters, so that the foreign matter removing efficiency of the filter device FS can be greatly improved. Further, the oil receiving rib 15 is integrally formed with the casing 1 in a small size as a rib for reinforcing the casing, so that the strength / rigidity of the casing 1 can be increased and the filter device FS can be made small and simple. .. It is needless to say that the filter device FS can be applied not only to the transmission TM but also to an engine, a differential device, or various processing machines equipped with a gear mechanism.
