Study on Tooth Wear of Spur Gears Under the Mixed Elastohydrodynamic Lubrication
To study the wear evolution process and wear law of involute spur gears under the mixed elastohydrodynamic lubrication (EHL) and consider the lubrication conditions, thermal effects and load changes in the wear process of gear pairs, a wear model of gear pairs under mixed EHL is established. The too...

| description | To study the wear evolution process and wear law of involute spur gears under the mixed elastohydrodynamic lubrication (EHL) and consider the lubrication conditions, thermal effects and load changes in the wear process of gear pairs, a wear model of gear pairs under mixed EHL is established. The tooth surface wear depth, contact temperature and contact pressure are calculated, and the changes of tooth surface contact pressure and contact temperature in the wear process of the gear pairs are analyzed. The results show that the wear amount at the meshing-in point of the gear pairs is large, and the tooth surface wear can reduce the contact pressure and contact temperature at the meshing-in point.The wear rate near the meshing-in point decreases with the gear meshing. Besides, the influence of tooth surface roughness, input torque and rotational speed on the wear law of spur gear is analyzed. The results show that the reasonable design of gear parameters is beneficial to resist gear wear. |
