Title (EN) HYDROGENATED NITRILE RUBBER COMPOSITION AND DRIVETRAIN OIL SEAL
(FR) COMPOSITION DE CAOUTCHOUC DE NITRILE HYDROGÉNÉ ET JOINT D’HUILE POUR TRANSMISSION
(JA) 水素化ニトリルゴム組成物及びドライブトレイン用オイルシール
Abstract: front page image
(EN)The present invention addresses the problem of providing a hydrogenated nitrile rubber composition and a drivetrain oil seal capable of suppressing seal noise even with advanced seal wear or under dry lubrication devoid of grease. This hydrogenated nitrile rubber composition contains 10 to 55 parts by weight of wollastonite and 10 to 55 parts by weight of graphite as additives in relation to 100 parts by weight of hydrogenated nitrile rubber, and the total of these additives is 50 to 110 parts by weight. This drivetrain oil seal is composed of a cross-linked product obtained by crosslinking the hydrogenated nitrile rubber composition.
(FR)La présente invention aborde le problème consistant à produire une composition de caoutchouc de nitrile hydrogéné et un joint d'huile pour transmission capable de supprimer le bruit de joint même sous usure avancée du joint ou sous lubrification sèche sans graisse. Cette composition de caoutchouc de nitrile hydrogéné contient 10 à 55 parties en poids de wollastonite et 10 à 55 parties en poids de graphite comme additifs liées à 100 parties en poids du caoutchouc de nitrile hydrogéné, et le total de ces additifs est de 50 à 110 parties en poids. Le joint d'huile pour transmission est composé d'un produit réticulé obtenu par réticulation de la composition de caoutchouc de nitrile hydrogéné.
(JA)本発明は、シールの摩耗が進行しても、あるいはグリースがないドライ潤滑下においても、シール鳴きを抑制できる水素化ニトリルゴム組成物及びドライブトレイン用オイルシールを提供することを課題とする。本発明の水素化ニトリルゴム組成物は、水素化ニトリルゴム100重量部に対して、充填剤として、10~55重量部のウォラストナイトと、10~55重量部のグラファイトとを含有し、これらの充填剤の総量が50~110重量部である。また、本発明のドライブトレイン用オイルシールは、該水素化ニトリルゴム組成物を架橋して得られた架橋体により構成される。
