Description
Summary:The ultimate load carrying capacity of journal bearings with different materials and surface treatment processes was studied in the present work. The load carrying capacity and backside temperature of bearing were examined using a bearing fatigue test machine (Glacier Vandervel, made in UK). The results showed that the copper-based sputtering bearing has the highest ultimate bearing capacity and the fatigue strength reaches 131.3 MPa. The bearing capacity of copper-based electroplated bearings is 99.7 MPa, which is lower than that of copper-based sputtering bearings. The bearing capacity of high tin aluminum alloy is obviously higher than that of white alloy bearing, and the bearing capacity of the two bearings is 72.7 MPa and 36.3 MPa, respectively. Finally, the mechanisms of fatigue failure of the bearings were analyzed.
