［産業上の利用分野］
本考案はベアリングシールを保護しその密封を
助けるフリンガーに関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a flinger that protects and helps seal a bearing seal.
［従来の技術］
従来、シール取付空間が少ないベアリングを密
封するには、その狭い間隔故充分なシール性能が
発揮されずバツクアツプシールとかフリンガーな
どの補助部品を設置して外部からの泥、水、異物
に対しベアリングシールを保護し密封を補助して
いる。しかし、該バツクアツプシールは高価であ
るため安価で効果的なフリンガーの開発が望まれ
ていた。[Conventional technology] Conventionally, in order to seal a bearing with a small seal installation space, sufficient sealing performance could not be achieved due to the narrow spacing, and auxiliary parts such as back-up seals and flingers were installed to prevent mud and water from outside. , protects the bearing seal from foreign objects and assists in sealing. However, since the back up seal is expensive, it has been desired to develop an inexpensive and effective flinger.
以下、図面を参照しつつ詳述する。 A detailed description will be given below with reference to the drawings.
このフリンガーの従来例を挙げると、第１図に
示すような構成がなされている。すなわち、ベア
リングシール１付ベアリング２の外側の固定ハウ
ジング３内に位置し回転部材４に取り付けられる
断面形状でＬ字形状を有するフリンガー５を設置
している。 A conventional example of this flinger has a configuration as shown in FIG. That is, a flinger 5 having an L-shaped cross section is installed, which is located inside the fixed housing 3 outside the bearing 2 with the bearing seal 1 and is attached to the rotating member 4.
［考案が解決しようとする課題］
しかしこの構造では、泥、水、異物の侵入に対

ベアリング２外及びハウジング３外へ全て有効に
排出することは不可能に近く、徐々にハウジング

封不良を発生させた。[Problems to be solved by the invention] However, with this structure, the flinger 5 is located inside the housing 3 and has only the function of swinging it toward the housing 3 when dirt, water, or foreign matter enters. It is almost impossible to effectively discharge all the foreign matter into the housing 3, and the foreign matter gradually accumulates in the housing 3 and reaches the bearing seal 1, weakening the sealing effect or, in the worst case, causing a sealing failure.
本考案はこのような欠点を除去して安価でかつ
効果的な振り切り作用を行うフリンガーを提供す
るものである。 The present invention eliminates these drawbacks and provides a flinger that is inexpensive and provides effective swinging action.

A flinger A is located in a housing 3 for fixing a motor vehicle, and is installed on a rotating member 4 of a wheel portion such as a drive shaft of an automobile; as shown in FIG. It has a bent fitting part 6, and has a convex ring 7 having a U-shaped cross section in the outward direction, which is continuous with the L-shaped outer circumferential part, and further has an outer circumferential end 8 bent in the outer circumferential direction to form a cross-sectional shape. It is formed into an approximately 〓 shape.
［作用］
本考案はこのような構造であるから次のような
大きな作用効果を発揮する。[Function] Since the present invention has such a structure, it exhibits the following great effects.
すなわち、第３図に示すごとく、泥、水、異物
等のベアリング２内部への侵入を二通りの方向に
分けてそれぞれ説明すると、まず外周側（第３図
では上方）からの侵入方向Ｂに対し、泥水等はハ
ウジング３端面をつたい該フリンガーＡの凸出環
部７の頂部に達し、さらには回転部材４にまで到
達するが、該凸出環部７に付着した泥水等は凸出
環部７の外周側肩部の回転により振り切られ回転
部材４の付着分も同様に回転力によつて振り切ら
れる。このとき該フリンガーＡの設置される位置
は、ハウジング３の外側面の外部に露出する端面
に対して該凸出環部７頂面が回転軸方向に同一面
上かまたは僅かに奥まつた位置に配置すると泥水
の付着を少量として振り切り効果を高められるの
で好ましい位置となる。 That is, as shown in Fig. 3, the intrusion of mud, water, foreign matter, etc. into the inside of the bearing 2 is divided into two directions and explained respectively. On the other hand, muddy water, etc., travels along the end surface of the housing 3 and reaches the top of the protruding ring part 7 of the flinger A, and further reaches the rotating member 4, but the muddy water, etc. attached to the protruding ring part 7 comes out The rotation of the outer circumferential shoulder of the ring portion 7 causes the portion attached to the rotating member 4 to be shaken off as well by the rotational force. At this time, the position where the flinger A is installed is such that the top surface of the protruding ring portion 7 is on the same plane in the direction of the rotational axis or is slightly recessed from the end surface exposed to the outside of the outer surface of the housing 3. This is a preferable position because it reduces the adhesion of muddy water and increases the effect of shaking it off.
次に、斜め横からの侵入方向Ｃに対しては、該
凸出環部７及びＬ字形環着部６がこれに付着する
泥水を前記した振り切り作用をもつて振り切り、
また、外周端部８に近い空間部分に侵入付着する
ものは前記凸出環部７の振り切り作用が引き起こ
す負圧によつて該空間から外部方向に引き出さ
れ、該凸出環部７の肩部によつて悉く外部へ振り
切られるからハウジング３内部あるいはベアリン
グ２内部への泥水の浸入は極めて少ない。それで
もフリンガーＡの外周先端８にまで水分の侵入を
許した場合、量的には前記振り切り負圧効果によ
つてごく少量しか浸入を許さず、回転する前記外
周先端８の遠心力によつて簡単に空気中に飛散昇
華せしめる。 Next, in the direction of intrusion C from the diagonal side, the protruding ring part 7 and the L-shaped ring attachment part 6 shake off the muddy water adhering thereto with the above-mentioned shake-off action,
Furthermore, objects that enter and adhere to the space near the outer peripheral end 8 are pulled out from the space by the negative pressure caused by the shaking off action of the protruding ring 7, and are pulled out from the space toward the outside by the shoulder of the protruding ring 7. Since the muddy water is completely shaken off to the outside by the muddy water, there is extremely little intrusion of muddy water into the inside of the housing 3 or the inside of the bearing 2. Even so, if moisture is allowed to enter the outer peripheral tip 8 of the flinger A, only a small amount is allowed to enter due to the negative pressure effect, and the centrifugal force of the rotating outer peripheral tip 8 allows moisture to enter easily. It is dispersed into the air and sublimated.
［考案の効果］
このように一つのフリンガーで二つ以上のフリ
ンガーの働きをするので大変効果的なシール性能
を発揮する。[Effects of the invention] In this way, one flinger functions as two or more flingers, so it exhibits very effective sealing performance.
また、従来のフリンガー５と比較して本考案の
フリンガーＡは表面積が大きいため重量的に不利
益になる等の考えに及ぶが、径方向で凹凸形状を
有する故薄い材料で充分な強度を各コーナーが保
ち、従つて、重量負担を増加させるものではな
い。 In addition, compared to the conventional Flinger 5, the Flinger A of the present invention has a larger surface area, which may be disadvantageous in terms of weight. The corners hold and therefore do not increase the weight burden.
以上の説明のように、本考案は断面形状でほぼ
〓形状を有した簡単な環構造で強力な振り切り効
果を上げ内部に位置する密封装置を完壁に保護す
ることができる理想的なフリンガーである。 As explained above, the present invention is an ideal flinger that has a simple ring structure with a cross-sectional shape that is approximately square, and can achieve a strong swinging effect and completely protect the sealing device located inside. be.
