Simulation Analysis of the Lubrication Flow Field of an Electric Vehicle Reducer
[Purposes]In order to study the influence of an electric vehicle reducer at different input speed,lubricating oil level and lubricating oil temperature on the distribution of oil particles,the power loss of gear mixing oil,and the bearing lubrication performance,the analysis of the lubrication effect of the internal cavity of an electric vehicle reducer and the related study of gear stirring oil power loss are carried out.[Methods]In this paper,the simulation analysis is carried out based on the improved semi-implicit moving particle method(MPS)in ShonDY software.The data of the internal flow field of the re-ducer are obtained through the built-in post-processing function.According to the obtained data,the ef-fects of different input speeds,lubricating oil level and lubricating oil temperature on the distribution of oil particles,the power loss of stirring oil and the lubrication performance of the bearing are analyzed.[Findings]The analysis and study of the simulation data can show that different input speed and lubri-cating oil level have significant effects on the distribution of oil particles,the power loss of of stirring oil and the bearing lubrication performance,and the lubricating oil temperature has little influence on the lu-brication effect,oil particle distribution and the power loss of stirring oil.[Conclusions]The obtained re-sults will provide a reference for the design of the internal cavity and gear of an electric vehicle reducer.
