Title (EN) LUBRICATING OIL COMPOSITION, LUBRICATING METHOD, AND TRANSMISSION
(FR) COMPOSITION D’HUILE LUBRIFIANTE, PROCÉDÉ DE LUBRIFICATION, ET BOÎTE DE VITESSES
(JA) 潤滑油組成物、潤滑方法、及び変速機
Abstract:
(EN) A lubricating oil composition is provided which achieves both a high viscosity index and a high shear stability, and which contains (1) a synthetic oil that has a 2.5 mm2/s or lower kinematic viscosity at 100°C and (2) a polymethacrylate that has a prescribed structural unit and has a monovalent functional group containing an oxygen atom in the molecule; a lubricating method and a transmission that use said composition are also provided.
(FR) La présente invention décrit une composition d’huile lubrifiante qui permet d’atteindre à la fois un indice de viscosité élevé et une stabilité élevée au cisaillement, et qui contient (1) une huile synthétique qui présente une viscosité cinématique de 2,5 mm2/s ou inférieure à 100 °C et (2) un polyméthacrylate qui possède un motif structurel prescrit et possède un groupe fonctionnel monovalent contenant un atome d’oxygène dans la molécule ; un procédé de lubrification et une boîte de vitesses qui utilisent ladite composition sont également décrits.
(JA) 高い粘度指数と高いせん断安定性とを両立する(1)100℃動粘度が2.5mm/s以下の合成油、及び(2)所定の構造単位を有する、分子中に酸素原子を含む1価の官能基を有するポリメタクリレートを含有する潤滑油組成物、これを用いた潤滑方法及び変速機を提供する。
