摘要：

Reversing of the gear causes the deterioration of the working condition of the gear system and is unfavorable to the maintenance of gear lubrication. In order to explore lubrication performance of asymmetric gear under reversing working conditions, transient elastohydrodynamic lubrication performance of asymmetric polymer gear reversing conditions is analyzed with multiple grid method. The elastohydrodynamic lubrication properties of the asymmetric gear and symmetric gear under the reversing working condition are compared. The elastohydrodynamic lubrication properties of asymmetric gear under the condition of forward and the reversing operation is comparatively analyzed.The effects of different forms of rotational speed change and the impact on transient elastohydrodynamic lubrication performance of asymmetric polymer gear under the working condition of reversing is analyzed. The results show that under the reversing condition, the thickness of lubricating oil film decreases greatly at the reversing point, which is the dangerous point of gear lubrication failure. Asymmetric design of gears can improve the lubrication performance during reversing operation. The sinusoidal deceleration and sinusoidal acceleration in the reversing process is more favorable to the elastohydrodynamic lubrication performance of the gear than other forms of speed variation under the reversing condition. The impact is not conducive to the lubrication of asymmetric gear under reversing condition. © 2022 Editorial Office of Chinese Journal of Mechanical Engineering. All rights reserved.
