润滑脂是常用的轴承润滑材料。从润滑机理来看,润滑脂和润滑油并无多大差异。为什么有些轴承的润滑要使用润滑脂,而不使用润滑油?归根到底,是由于润滑脂具有一些独特的流变性质。润滑脂是已被稠化为半固体的润滑油,具有一定的稠度和触变性,只有在足够的外力作用下才能产生变形和流动,当轴承运转时成为粘度接近基础油的流体而起润滑作用,除去外 Grease is commonly used bearing lubrication materials. From the lubrication mechanism point of view, there is not much difference between grease and lubricating oil. Why do some bearings use greases instead of greases? In the final analysis, greases have some unique rheological properties. Grease is a thickening of semi-solid lubricating oil, has a certain consistency and thixotropy, only under the action of sufficient external force to produce deformation and flow, as the bearing operation becomes a viscosity close to the base fluid and lubrication , Except outside
