Abstract

COMPOSIÇÃO DE GRAXA. A presente invenção refere-se a uma graxa lubrificante usada para lubrificar elementos mecânicos tendo uma esfera deslizante alternada interposta entre os mesmos e mantendo a resistência à descamação mesmo sob uma carga alta em elementos mecânicos tendo uma esfera deslizante alternada interposta entre os mesmos. A presente invenção, portanto, fornece uma composição de graxa compreendendo um óleo de base (a), um composto de diureia (b), um composto de amida (c) e um composto de tiofosforoso ou um composto de éster de ácido tiofosfórico (d), em que o composto de diureia (b) inclui um composto representado pela Fórmula (1), R1-NHCONH-R2-NHCONH-R3 (1) em que R1 e R3 representam um grupo hidrocarboneto alifático acíclico tendo de 8 a 20 átomos de carbono, e R2 representa um grupo difenilmetano.GREASE COMPOSITION. The present invention relates to a lubricating grease used to lubricate mechanical elements having an alternating sliding ball interposed therebetween and maintaining peeling resistance even under high load in mechanical elements having an alternating sliding ball interposed therebetween. The present invention therefore provides a grease composition comprising a base oil (a), a diurea compound (b), an amide compound (c) and a thiophosphorus compound or a thiophosphoric acid ester compound (d ), wherein the diurea compound (b) includes a compound represented by Formula (1), R1-NHCONH-R2-NHCONH-R3 (1) wherein R1 and R3 represent an acyclic aliphatic hydrocarbon group having from 8 to 20 atoms carbon, and R2 represents a diphenylmethane group.
