Oil seal

Abstract

Abstract Translated from Japanese (57)【要約】 【課題】オイルシールにおいて、簡易に製作できて、し かも安定なシール性能および回転軸の回転振れに対する 良好な追従性を発揮できるようにすること。 【解決手段】回転軸Ｂの外周面に対して斜めに当接させ られるオイルシールＡであって、軸方向に重ね合わされ る二つの環状シート１，２と、両環状シート１，２を結 合する結合部材３，４，５とを備え、両環状シート１， ２には、それぞれ周方向所要間隔おきに径方向内向きに 突出する舌片１１，２１が設けられていて、一方環状シ ート１と他方環状シート２とを位相をずらして重ね合わ せることにより両環状シート１，２の隣り合う舌片１ １，２１間の離間領域に互いに相手となる環状シート ２，１の舌片２１，１１が位置させられている。 (57) [Object] To provide an oil seal that can be easily manufactured, and that can exhibit stable sealing performance and good follow-up performance against rotational runout of a rotating shaft. An oil seal A obliquely abutted against an outer peripheral surface of a rotating shaft B, which couples two annular sheets 1 and 2 overlapped in the axial direction and both annular sheets 1 and 2. And two connecting sheets 3, 4 and 5. 2 are provided with tongue pieces 11 and 21 projecting radially inward at required intervals in the circumferential direction, and the two annular sheets 1 and the other annular sheet 2 are superposed with their phases shifted from each other. Adjacent tongue pieces 1 of sheets 1 and 2 The tongue pieces 21 and 11 of the annular sheets 2 and 1 that are mating with each other are located in the separation area between the first and the second sheets 21.
