Abstract: front page image
(EN)An oil seal (1A) has an outer member (2) fitted to a crankcase (100), an inner member (3) integrally rotatably fitted to a crankshaft (101), and a first movable lip (4) disposed in the gap (G1) formed by the outer member (2) and the inner member (3). The first movable lip (4) is disposed such that it is not in contact with the outer member (2) when rotation of the crankshaft (101) is stopped and that it is displaced in the direction to approach the outer member (2), coming into contact with the outer member (2) to close the gap (G1).
(FR)La présente invention concerne un joint étanche à l'huile (1A) qui comprend un élément externe (2) fixé à un carter de moteur (100), un élément interne (3) incorporé de manière rotative à un vilebrequin (101) et une première lèvre amovible (4) disposée dans l'espace (G1) formé par l'élément externe (2) et l'élément interne (3). La première lèvre amovible (4) est disposée de manière à ne pas être en contact avec l'élément externe (2) lorsque la rotation du vilebrequin (101) est arrêtée, à se déplacer dans la direction se rapprochant de l'élément externe (2) et venir au contact de ce dernier (2) afin de fermer l'espace (G1).
(JA) オイルシール1Aは、クランクケース100に装着されるアウター部材2と、クランク軸101に一体回転可能に装着されるインナー部材3と、アウター部材2とインナー部材3とで形成される隙間G1に配置され、かつクランク軸101の回転停止時にアウター部材2と非接触の状態でインナー部材3に設けられるとともに、クランク軸101の回転速度の上昇に伴って隙間G1が塞がれるようにアウター部材2に接近する方向へ変位してアウター部材2に接触する第1可動リップ4と、を備えている。
