半流体脂由于其独特的流变性,兼具有润滑油与脂的优点而获得越来越广泛的应用.该文利用毛细管粘度计和RV2型流变仪研究了半流体脂的弹流润滑机理.“,”Semi - fluid grease is used more and more for its special rheology and possessing advantages of oils and greases. In this paper, the capillary viscometer and rheometer RV2 are used to investigate the relations between apparent viscosity and shear rate of semi -fluid at different temperature. Its EHL mechanism is investigated too.
