“…Rolling contact fatigue (RCF) test. Rolling contact fatigue tests of PEEK thrust bearings were done using an RCF test machine [1][2][3][4][5]. All of the tests were carried out in water at a rotation speed of 1200 rpm or 1800 rpm.…”

Bearings have been used in various environments. Recently, small and light-weight bearings are developed in order to downsize mechanical components. Polymer bearings, such as PEEK (Poly-Ether-Ether-Ketone), PTFE (Poly-Tetra Fluoro-Ethylene) and PPS (Poly-Phenylene-Sulfide-Resin), are designed because of advantages of light weight, high corrosion resistance and self-lubricating. However, industrial design standards of these bearings have not been established yet, i.e., the relation between working conditions, shape, geometry, and lives of bearing components under RCF (Rolling Contact Fatigue) is not fully understood as well as crack propagation, wear and/or failure. In this study, we focused on the manufacture process of groove curvature decreasing contact stress, and observed cracks and flaking failures on groove surfaces and cross sections. Based on these observations, we investigated the relation between the groove geometry and lives of all-PEEK thrust bearings in water.

This comprehensive review article provides a cumulative insight into the tribology and the surface topography of the components of the electric vehicles (EV) and hybrid electric vehicles (HEV) that are subjected to friction and wear under their conventional operation. The comparison between the components that are native to EV and HEV and components that are common for both vehicle types are discretely discussed. The overall influence of such a tribology-critical component on the life and efficiency of the EV and HEV is indicated in this article as well. Identification of the research gaps in the key areas paves an avenue to channel the research and focus upon improving the efficiency of EV and HEV by improvising the design, materials, power harness, and lubrication techniques. Finally, the future scope of the global EV and HEV markets are discussed to signify the importance of the studies on the tribology of the trending automobile field. RECEIVED

[11][12][13][14][15][16] In the present study, grooves of new specimens were made with feedrate of 0?12 mm rev 21 , which was finer than in our previous study. RCF test was performed and the detailed observations were made to find out the effect of feedrate on flaking failure.…”

There were two procedures about surface failure in rolling contact fatigue (RCF): wear process and crack propagation. To find out the failure pattern in polyphenylenesulphide (PPS) polymer thrust bearings under water condition, RCF tests were introduced. In our previous study, the relationship between wear loss, rotation speed and thrust load of polymer bearings under RCF in water was investigated; it was concluded that the main reason for PPS polymer thrust bearings failure in water was flaking due to surface crack propagation. In this study, the detailed surface profiles under heavy load and crack observation were made. Furthermore, effect of machining conditions on flaking was investigated. It is concluded that flaking due to crack propagation was responsible to fatigue failure of PPS polymer thrust bearings under water condition, and slower feedrate in race process improves life time of PPS bearings.
