为了提高PPS- ptfe混合轴承的径向承载能力和磨损损失，基于陶瓷轴承的球半径r设计了PPS- ptfe混合轴承中PPS内圈的沟槽形状。采用原始（r*1.0）和改进（r*1.1）内圈的PPS-PTFE混合轴承进行滚动接触疲劳试验。使用rl的轴承的径向承载能力。1内圈比使用r1.0内圈的轴承容量提高了150%。r1.1内圈轴承的工作温度在40℃时稳定，而r1.0内圈轴承的工作温度在100℃以上迅速上升并发生热失效。此外，使用r1.1内圈的轴承的磨损量低于r1.0。因此，沟槽形状影响着PPS-PTFE混合轴承的摩擦学性能。
In order to improve the radial load capacity and wear loss of the PPS-PTFE hybrid bearings, the groove shape of the PPS inner ring in the PPS-PTFE hybrid bearing was designed based on ceramic bearing’s ball radius (r). The rolling contact fatigue tests were performed by using the PPS-PTFE hybrid bearings with the original (r*1.0) and modified (r*1.1) inner rings. The radial load capacity of the bearing using the rl.1 inner ring was improved 150% over the capacity of the bearing using the r1.0 inner ring. While the operation temperature of the bearing with the r1.1 inner ring was stable at 40 °C, that of the bearing with the r1.0 inner ring incresed rapidly over 100 °C and thermal failure occurred. Moreover, the wear loss of the bearings with the r1.1 inner ring was lower than that of the r1.0. Thus the groove shape influenced the tribology performance of the PPS-PTFE hybrid bearings.
