Title: GREASE COMPOSITION FOR CONSTANT VELOCITY JOINTS, HAVING SUPERIOR HEAT RESISTANCE AND LOW FRICTION FORCE
Abstract:
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.
