摘　　要：为保证电机满足防水防尘要求,结合新型插电式混合动力系统中结构参数并针对使用情况进行密封件选型,为试验验证做好基础。油封通过选型后,无法通过计算或者仿真来确定可靠性,需要相应的试验验证来确认设计是否满足实际需求。根据零件的特性和实际使用情况进行了油封单体试验和混合动力系统高速试验,并最终通过了试验。In order to meet the IP67 requirements of the electric motor,combined with the new plug-in hybrid powertrain system in the structural parameters and the use of sealing parts to complete the selection for the test to verify the foundation.After sealing selection,it is impossible to validate the reliability by calculation or simulation.Need to carry out the corresponding test design verification to confirm the design reasonable to meet the actual needs.According to the characteristics of the parts and the actual use,complete the oil seal monomer test and hybrid powertrain system high-speed test,and finally through the above test.
