“…Advanced non-linear finite element methods have been employed to understand gear surface contact behaviour including micro geometry modifications. In previously published work by a couple of the authors progress had been made in understanding the effect of tip relief on PEEK gear contact conditions using 2D nonlinear finite element methods [22]. Further progress has been made using advanced 3D non-linear finite element methods to consider full geometry and real contact behaviour.…”

Abstract.Polymer are now widely used as substitute material for steel gear in low load devices. Its failure differs from gears made of steel, thus it is important to categorize the failures shown by polymer gears. Several previous studies noted that wear detection, microstructure surface condition monitoring, weight loss and temperature detection can be used in detecting failure of polymer gear. This article reviews the failure detection method mentioned above. Other researcher works were studied and their findings were extracted in order to identify the methods they used. The most common method used was wear detection and it was supplemented by other methods such as microstructure surface condition monitoring. Failures shown by polymer can be concluded to be tooth breakage, tooth deformation, material removal and surface fatigue.

“…Compared with metals, polymer materials have advantages such as lightweight, reduced noise and self-lubricating properties which make their use in automotive, aerospace, medical, industrial applications highly desirable [1][2][3][4][5][6][7][8][9]. On the other hand, the mechanical strength and thermal stability of polymers are lower than those of metals, and therefore they tend to suffer from failures such as wear, local melting and pitting when used in severe conditions [10][11][12][13].…”

Effect of Lubrication on Friction and Wear Properties of PEEK with Steel Counterparts

et al. 2019

Poly-Ether-Ether-Ketone (PEEK) has been widely used for tribological applications with steel counterparts because of its superior mechanical and self-lubricating properties. Fluid lubrication has the potential to further improve the performance of PEEK/steel contacts but its effect has been shown to depend on the operating conditions. To elucidate these aspects and establish the mechanism of fluid lubrication, the friction and wear properties of the PEEK/steel contacts in both dry and poly-α-olefin (PAO) lubricated conditions were investigated by tribological tests and surface analytical techniques. The nanoindentation measurements showed that lubrication with PAO had a softening effect on the wear track of PEEK, but no correlation was established with the wear of PEEK. The tribological behavior, for both dry and lubricated contacts, was correlated with the thickness of PEEK transfer films on the steel counterparts. The thickness of these films, as determined by Electron Probe Micro Analysis (EPMA) and X-ray Photoelectron Spectroscopy (XPS), was controlled by the rates of their formation and removal and depended on the operating conditions. Moreover, lubrication with PAO inhibited not only the formation but also the removal of PEEK transfer films. This study thus sheds light on the mechanism of fluid lubrication of the PEEK/steel contacts.
