INVESTIGATION OF GEAR PERFORMANCE OF (MLNGPs) AS AN ADDITIVE ON POLYAMIDE 6 (PA 6) SPUR.

Abstract

The aim of his study estimated the effects of (MLNGPs) as an additive on Polyamide 6 spur gear performances. These include strength, elastic modulus, thermal stability, dynamic mechanical analysis, moisture absorption, and wear characteristics. The nanocomposites gear was made by melt mixing method and injection molded into thick flanges. The wear experiments were performed using test rig under external torques of 13 and 16 Nm with different concentration 0.1, 0.3 and 0.5 wt% MLNGPs. The result showed tensile strength increased30%, Vickers micro hardness value increased up to 25%, storage modulus E‟ is increased up to 37% and glass transition temperature is increased up to 14%. On the other hand TGA result shows that the Tonest increased up to 7.5% and Td increased up to 2%, and wear decreased by 35% at 16 Nm and 54% at 13 N.m
