Optimized design of spray parameters of oil jet lubricated spur gears
2018
Abstract The lubrication process in jet lubrication is significantly influenced by different spray parameters under different injection conditions. The computational fluid dynamics model of the jet lubrication process is established. The jet lubrication process is evaluated with different spray parameters, including the spray angle, position, and distance. The results indicate that for into mesh lubrication, a suitably small angle inclined to driving gear, deviation of injection position from into mesh side, and larger spray distance improve the lubrication effect. With out of mesh lubrication, a small angle inclined to driven gear, deviation of injection position from out of mesh side, and smaller spray distance provide the optimal lubrication effect. Finally, the analysis results are verified by experimental results.
