摘　　要：浮动油封在煤矿机械中应用广泛,但由于摩擦损伤、橡胶圈黏弹性等影响,其在使用中容易出现油液渗漏现象。由于应力松弛使得一定时间后实际压力小于O形圈密封所要求的最小压力,不能继续起到密封作用,通过实验研究了浮封与时间相关的黏弹性特征,对其失效分析和正确使用具有重要指导意义。Floating oil seal is widely used in coal mine machinery, but due to friction damage, rubber ring viscoelasticity and other effects, it is easy to appear oil leakage phenomenon in use. Since the minimum pressure stress relaxation after a certain period of O-Ring sealing requirements, can not continue to play a role time makes the actual pressure less than in sealing. The viscoelastic characteristics related to time are studied experimentally, which has important guiding significance for the failure analysis and correct use of floating seals.
