Development of A Mobile Constant Velocity Joint Polyurea Grease
A mobile Constant Velocity Joint(CVJ)polyurea grease was developed.Through inspection of the base oil,thickener and additives,it was determined that mobile CVJ polyurea grease consisted of(naphthene base oil and mineral oil)blended base oils,the polyurea base soap,0.5%of sulfurized olefin extreme pressure additive,2.0%of the Zinc Dialkyldithiophosphates(ZnDDP)anti-wear & extreme pressure additive,0.5%of phosphate ester-based anti-wear additive and 1.5%of the Molybdenum Dithiocarbamate(MoDTC)anti-wear additive.It had good anti-wear performance and lower friction coefficient,and had the high and low temperature,meeting the requirement of the durability bench test and achieving the development goal.(Charts4 Tables4 References4)
