ABSTRACT. Polymer composite gears widely used these days as substitute material for steel gear in different load conditions and devices. Its failure mode differs from gears made of steel, thus it is important to categorize the failures shown by polymer composite gears. Several previous studies noted that wear detection, surface condition monitoring, weight loss and temperature detection can be used in detecting failure of polymer composite gear. Most pure polymer gears cannot with stand high temperature, the gear simply melts instead of creating crack. 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, temperature detection and it was supplemented by other methods such as surface condition monitoring. Failures shown by polymer composite can be concluded to be tooth breakage, tooth deformation, material removal and surface fatigue.The review also concluded that the usage of reinforced polymer materials did a considerable improvement in polymer gears strength and performance.
