Rolling bearings are increasingly used in special environmental conditions such as vacuum, particularly high or low temperatures in radiant environments or in contact with aggressive media, and therefore cannot be operated with conventional lubricants such as oil or grease. Instead, solid lubricated rolling bearings are used, which are initially lubricated by coating the raceways or rolling elements and whose lubrication receives an additional lubricant source through the use of the rolling bearing cage as a lubricant reservoir... In the present work, tribological model tests as well as component tests were carried out to visualize the wear and transfer processes in the bearings. With the help of modern surface analysis techniques, the lubricant wear and lubricant transport were examined in detail on a microscopic level.weiterlesen
