Wear Resistance Assessment of Fluoropolymer Coated Gears
Journal Title: Analele Universitatii "Eftimie Murgu" Resita. Fascicula de Inginerie - Year 2017, Vol 24, Issue 1
Abstract
Power transmissions that incorporate gears dissipate a significant amount of energy and noise. Thus, any improvement in their performance​ contributes to reducing energy consumption and noise pollution. In recent years, the opportunities offered by conventional technologies to increase gear performance have been fully exploited. Therefore, sur-face depositions on gear teeth have become increasingly important technologies in achieving objectives such as: improving energy per-formance, providing greater protection against superficial defects, in-creasing load capacity and reducing acoustic emissions generated dur-ing operation. However, gear coating technologies have begun to be developed, but the investigations are still insufficient. In this study, we carried out wear resistance investigations performed on fluoropolymer coatings for different working speeds, loads and lubrication conditions. The results point out that the deterioration rate of the coating in-creases with the increase of the working speed and the applied load. In addition, a slight lubrication, applied at the start of testing, leads to a noticeable improvement in wear behaviour. This study represents one step further in understanding the wear process of fluoropolymer coated gears.
