Abstract: Polymer & polymer composite gears find increasing application because of the low material manufacturing cost, light weight & quiet operation compared with metal gears. Generally thermoplastic polymers like acetal polymer & nylon polymer are used for gear applications. But acetal and nylon gears have low load carrying capacity. To improve the performance of gears, geometry modification had been done like tooth width modification & cooling holes on tooth surface. But, for high power applications, these materials show poor performance. Therefore, it is necessary to select the polymer which has good mechanical properties & good thermal stability. Poly-ether-ether-Ketone (PEEK) has high strength & stiffness, low coefficient of thermal expansion which is required for gears. The comparative performance spur gears of 30% glass filled PA66 and 30% glass filled PEEK was investigated in this study. The results shows that 30% glass filled PEEK gears have high wear resistance and high torque transmission capacity as compare with 30% glass filled PA66 gears.
