Investigations on Varying Compositions of Nylon 6 Polymer Matrix Composites for Wear Reduction in Application to Gears

Abstract

In power transmission systems, gears are the most essential parts. Gear failure would happen at any regular working cycles and it must be avoided with special care. The mode of failure suggests that optimum material and suitable post processing has to be done. Industry demands more efficient, reliable, and lightweight gears. Hence more efficient, reliable, and lightweight gears must be developed and manufactured. Eventhough lot of investment is being done on research and implementing new technologies while manufacturing gears, stills some failures is arised. Many physical factors, including the inappropriate materials composition, may induce gear failure. In this paper, some typical diverse materials, like nylon 6 and glass fibers are mixed with various volume proportions to enhance wear resistance and improve gear’s life. Polymer gears developed in this study offer more superior life than pure nylon gears. All the prepared specimen samples are tested to a variety of studies including Tensile, Compression, Flexural, Impact, TGA and Wear tests. Depreciation is not reducing low, however. 90% nylon 6 + 10 % Glass fiber to 10% nylon 6+ 90Glass fiber 10 % Nylon 6 has mixed for investigation. Based on the investigation, 70% of Nylon 6 + 30% glass fiber has high strength, low wear, and high wear resistance.
