本考案は、各種の流体やダストなどをシールするために用いられる密封装置に 関する。 The present invention relates to a sealing device used to seal various fluids and dusts.
【０００２】[0002]
軸受の内輪と外輪のように相対的に運動する２部材がある場合、軸受外部のダ ストが内部へ侵入したり軸受内部のグリースが外部へ漏出したりすることのない ように、内外両輪の間に密封装置が装着されており、この種の用途に用いられる 密封装置として従来から、ゴム状弾性材製の弾性リップを設けたリップ部材と、 この弾性リップが摺接するスリーブとを組み合わせたものが知られている。 If there are two members that move relative to each other, such as the inner ring and the outer ring of the bearing, the dust on the outer side of the bearing will not leak into the interior and the grease inside the bearing will not leak to the outside. A sealing device is installed between the two. As a sealing device used for this type of application, a combination of a lip member provided with an elastic lip made of rubber-like elastic material and a sleeve with which this elastic lip slides has been conventionally used. It has been known.

It is possible to seal between the lip member 1 and the sleeve 7 by 4, 5 and by the latter elastic lip 6 between the lip member 1 and the inner ring 12, and further between the sleeve 7 and the inner ring 12. it can. Therefore, it is possible to prevent dust or grease from leaking not only between the lip member 1 and the sleeve 7 but also between the sleeve 7 and the inner ring 12. Further, since the two elastic lips 4 and 5 which are in sliding contact with the sleeve 7 are provided, the sealing performance is high.
【００２０】 またリップ部材１が、スリーブ７に摺接するとともに受圧面を軸受の外側Ａへ 向けた対ダスト用の弾性リップ４，５と、内輪１２に摺接するとともに受圧面を 軸受の内側Ｂへ向けた対グリース用の弾性リップ６とを有しているために、前者 の弾性リップ４，５によってリップ部材１とスリーブ７との間を密封し、特にそ の受圧面の向きからしてダストの侵入を効果的に防止することができ、また後者 の弾性リップ６によってリップ部材１と内輪１２との間、延てはスリーブ７と内 輪１２との間を密封し、特にその受圧面の向きからしてグリースの漏出を効果的 に防止することができる。またスリーブ７に摺接する弾性リップ４，５が２本設 けられているために、密封性能が高い。Further, the lip member 1 is in sliding contact with the sleeve 7 and the elastic lips 4, 5 for dust whose pressure receiving surface is directed to the outer side A of the bearing, and the inner ring 12 are in sliding contact with the pressure receiving surface to the inner side B of the bearing. Since it has the elastic lip 6 for facing the grease, the former elastic lips 4, 5 seal between the lip member 1 and the sleeve 7, and particularly when viewed from the direction of the pressure receiving surface thereof, the dust. Can be effectively prevented from entering, and the latter elastic lip 6 seals between the lip member 1 and the inner ring 12, and thus between the sleeve 7 and the inner ring 12, and in particular the pressure receiving surface From the direction, it is possible to effectively prevent the grease from leaking.

Therefore, it is possible to prevent dust or grease from leaking not only between the lip member 1 and the sleeve 7 and between the sleeve 7 and the inner ring 12, but also between the lip member 1 and the outer ring 11.
【００２２】 またこれに加えて、リップ部材１の各弾性リップ４，５，６が受圧面の反対側 の面を摺接面としているために、受圧面に作用する圧力が大きくなったときに弾 性リップ４，５，６がスリーブ７または内輪１２に強く接触する。したがって弾 性リップ４，５，６が受圧面に作用する圧力の大きさに応じた密封性能を発揮す ることができる。In addition to this, since the elastic lips 4, 5, 6 of the lip member 1 use the surface on the opposite side of the pressure receiving surface as a sliding contact surface, when the pressure acting on the pressure receiving surface becomes large. The elastic lips 4, 5, 6 make strong contact with the sleeve 7 or the inner ring 12. Therefore, the sealing performance can be exhibited according to the magnitude of the pressure applied by the elastic lips 4, 5, 6 to the pressure receiving surface.
【００２３】 またこれに加えて、リップ部材１の軸受外側端面１ｃとスリーブ７の軸受外側 端面７ａとが面一となっているために、当該密封装置の装着に際して、リップ部 材１とスリーブ７との相対的な軸方向位置を確実に決めることができる。したが って弾性リップとスリーブ、特にスリーブ７の鍔部９に接触する弾性リップ５と この鍔部９との接触状態を一定に保ち、密封作用を安定化させることができる。In addition to this, since the bearing outer end surface 1c of the lip member 1 and the bearing outer end surface 7a of the sleeve 7 are flush with each other, when the sealing device is mounted, the lip member 1 and the sleeve 7 are mounted. The axial position relative to can be determined with certainty. Therefore, the contact state between the elastic lip and the sleeve, in particular, the elastic lip 5 contacting the collar portion 9 of the sleeve 7 and the collar portion 9 can be kept constant, and the sealing action can be stabilized.
