以OmniSeal 103A系列弹性蓄能密封圈为参考，提出密封夹套和与密封沟槽配合尺寸设计方法，并对弹性蓄能密封圈的结构进行优化，设计外唇面带有15°斜面的弹性蓄能密封圈JT1和外唇面为圆弧面的弹性蓄能密封圈JT2。设计实验从正反向摩擦力和密封性2个方面对两款弹性蓄能密封圈进行性能验证，并且与OmniSeal 103A系列中同规格密封圈性能进行对比。结果表明：JT1蓄能密封圈很大程度上提升了密封性能并且其抗摩擦性能也没有大幅下降，而JT2蓄能密封圈提升了抗摩擦性能，且密封性基本与OmniSeal蓄能密封圈相当。因此，JT1蓄能密封圈更适用于对密封性要求更高的场合，JT2蓄能密封圈更适用于对抗摩擦性要求更高的场合。
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.
