Based on the OmniSeal 103A series elastic energy storage seal ring,the design method of the size of the sealing jacket and the matching with the sealing groove was put forward.The structure of the elastic energy storage sealing ring was optimized,an elastic energy storage sealing ring JT1 with a 15° slope on the outer lip surface and an elastic energy storage sealing ring JT2 with a circular arc on the outer lip surface were designed.The designs experiments were carried out to verify the performance of the two elastic energy storage seals from two aspects,the forward and reverse friction force and the sealing performance,and the performance of the designed sealing ring was compared with that of OmniSeal 103A series sealing ring.The JT1 energy storage sealing ring greatly improves the sealing performance and its anti friction performance has not significantly decreased.While the JT2 energy storage sealing ring improves the anti friction performance and the sealing performance is basically equivalent to that of the OmniSeal energy storage sealing ring.Therefore,the JT1 energy storage sealing ring is more suitable for the conditions with higher sealing requirements,while the JT2 energy storage sealing ring is more suitable for the conditions with higher requirements for anti friction.
