摘　　要：密封寿命是影响电动工具适用寿命的关键因素和衡量电动工具性能的重要指标。简述唇形油封的密封结构和原理,分析电动工具转子轴动-静组合密封系统的机构和工作原理,对工作状态下油封唇口的位移和应力分布进行仿真,并通过试验验证密封系统的有效性。Sealing life is a key factor to influences the tool life, and an important index for judging the power tool per- formance. The structure and principle of lip seal was introduced. A sealing system included dynamic and static sealing used in the power tool armature shaft was introduced. The sealing lip strain and stress under working conditions was analyzed by using ABAQUS/CAE,and the sealing life was tested by experiment. The simulated and test results prove the effectiveness of this sealing system.
