A kind of perfluoropolyether(PFPE)grease for motor bearings was developed.Through the investigation of base oils,thickeners and additives,it is determined that the PFPE grease for motor bearings is composed of PFPE base oil,polytetrafluoroethylene(PTFE)thickener,3％white carbon black,3％zinc-containing organic anti-wear extreme pressure agent,3％sulfurized isobutylene anti-wear extreme pressure agent,2％nano calcium carbonate,and 3％organic borate ester anti-wear extreme pressure agent.The developed PFPE grease for motor bearings exhibits a wear scar diameter of 0.41 mm,a weld load(PD)of 7846 N,and a maximum non-seizure load of 1961 N.Additionally,the prepared PFPE grease shows good compatibility with rubber,achieving the research objectives.(Charts4 Tables9 References10)
