Abstract: front page image
(EN)Proposed is a grease composition for constant velocity joints, having superior heat resistance and lubricity and low friction force. The proposed grease composition for constant velocity joints comprises, based on the total weight of the grease composition, 5 to 25 wt % of a urea-based grease thickener, 0.1 to 3.0 wt % of diphenylamine, 0.1 to 10 wt % of a calcium salt, 1.0 to 10.0 wt % of molybdenum dithiocarbamate, 0.5 to 5.0 wt % of molybdenum dithiophosphate, 0.5 to 5 wt % of zinc dialkyldithiophosphate, 1.0 to 10.0 wt% of calcium sulfonate, 0.1 to 5.0 wt % of molybdenum sulfide, 0.1 to 5.0 wt% of graphite, with the remainder consisting of base oil.
(FR)La présente invention concerne une composition de graisse pour joints homocinétiques, présentant une résistance à la chaleur et un pouvoir lubrifiant supérieurs et une faible force de frottement. Ladite composition de graisse pour joints homocinétiques contient, rapporté au poids total de la composition de graisse, de 5 à 25 % en poids d'un épaississant de graisse à base d'urée, de 0,1 à 3,0 % en poids de diphénylamine, de 0,1 à 10 % en poids d'un sel de calcium, de 1,0 à 10,0 % en poids de dithiocarbamate de molybdène, de 0,5 à 5,0 % en poids de dithiophosphate de molybdène, de 0,5 à 5 % en poids de dialkyldithiophosphate de zinc, de 1,0 à 10,0 % en poids de sulfonate de calcium, de 0,1 à 5,0 % en poids de sulfure de molybdène, de 0,1 à 5,0 % en poids de graphite, le reste étant constitué d'une huile de base.
(KO)내열성 및 윤활성이 우수하여 저마찰력이 향상된 등속조인트용 그리스 조성물이 제안된다. 제안된 등속조인트용 그리스 조성물은 전체 그리스 조성물의 중량을 기준으로 하여 우레아계 그리스 증주제 5 내지 25 wt%, 디페닐아민 0.1 내지 3.0 wt%, 칼슘솔트 0.1 내지 10 wt%, 몰리브덴디티오카바메이트 1.0 내지 10.0 wt%, 몰리브덴디티오포스페이트 0.5 내지 5.0 wt%, 아연디알킬디티오포스페이트 0.5 내지 5 wt%, 칼슘설퍼네이트 1.0 내지 10.0 wt%, 몰리브덴설파이드 0.1 내지 5.0 wt%, 및 그라파이트 0.1 내지 5.0 wt% 및 잔량으로는 기유를 포함한다.
