很多干轴承材料是采用以青铜粉和玻纤作为填料的聚合物。在高度整合接触的推力轴承中,一些复合材料的单位磨损率(磨损系数K)随轴承压力的增大而急剧增大。然而,无填料的聚合物在极限轴承压力下,其单位磨损率却实际上保持不变。从一些PTFE基复合材料单位磨损率的增大中可看出,磨损机理从形成稳定的传递性薄膜变成磨屑磨损。将几种特定复合材料进行试验后表明,如果在推力轴承表面上开槽,使磨屑迅速进入槽内,则可使单 Many dry bearing materials are polymers that use bronze powder and glass fiber as the filler. In highly integrated contact thrust bearings, some of the composite wear rate (wear coefficient K) increases sharply with increasing bearing pressure. However, unfilled polymer under the limit bearing pressure, the unit wear rate is actually maintained. It can be seen from the increase of the unit wear rate of some PTFE-based composites that the wear mechanism changes from the formation of a stable transmissive film to abrasive wear. Several specific composite materials tested showed that if the surface of the thrust bearing grooves, so that debris quickly into the tank, you can make a single
