摘　　要：轴承温度每上升10℃~15℃,润滑脂的使用寿命要降低约50%。制备了一种能改善轴承温升的氟醚润滑脂。氟醚润滑脂由20%的全氟聚醚基础油,聚四氟乙烯稠化剂,聚脲预制皂及3.0%的二异辛基二硫代磷酸锌组成。该润滑脂的微锥入度为65单位,蒸发损失(149℃,24 h)为1.57%,钢网分油(100℃,24 h)为0.5%,烧结负荷(常温,1500 r/min)为3090 N,轴承温升3.0℃,可以满足高温长寿命轴承的润滑要求。(图4表2参考文献10)The service life of lubricating grease should be reduced by about 50%every 10℃~15℃rise of bearing temperature.A kind of fluoroether grease which could improve the temperature rise of bearing was prepared.The fluoroether grease was composed by 20%perfluoropolyether base Stock,polytetrafluoroethylene thickener,polyurea premade soap and 3.0%zinc diisooctyldithiophosphate.The micro cone penetration of the grease was 65 units,and the evaporation loss(149℃,24 h)was 1.57%,steel mesh oil separation(100℃,24 h)0.5%,weld load(room temperature,1500 r/min)was 3090 N,bearing temperature rise 3.0℃,which could meet the lubrication requirements of high temperature and long life bearings(.Charts4 Tables2 References10)
