Analysis of Transient Elastohydrodynamic Lubrication of Asymmetric Polymer Gear

Polymer gears are light and corrosion resistant, which can reduce noise and improve economic benefits. Correspondingly, polymer gear teeth are weaker than metal ones, so asymmetric design is adopted to improve the strength of polymer gear. In order to investigate the elastohydrodynamic characteristi...

description Polymer gears are light and corrosion resistant, which can reduce noise and improve economic benefits. Correspondingly, polymer gear teeth are weaker than metal ones, so asymmetric design is adopted to improve the strength of polymer gear. In order to investigate the elastohydrodynamic characteristics of asymmetric polymer gears, analysis of transient elastohydrodynamic lubrication of asymmetric polymer gears is carried out under water lubrication by using the multi-grid method. The water film pressure and thickness of asymmetric gear are compared with that of traditional symmetric gear. The influence of changing gear operating condition and considering gear tooth surface roughness on gear elastohydrodynamic lubrication analysis is studied. The results show that the elastohydrodynamic performance of gears can be effectively improved by asymmetric design. The pressure and film thickness of the lubrication film are greatly affected by rotational velocity and load. The roughness has a negative effect on elastohydrodynamic lubrication of asymmetric polymer gears and the tooth surface quality should be guaranteed in applications.
