摘　　要：本文叙述了机载雷达液压系统油路密封用O型密封圈的研制及其关键技术，采用聚四氟乙烯薄膜包覆后的密封圈与未包覆密封围相比具有摩擦系数低、损耗系数小、密封性能好等特点，提高了密封圈的可靠性和使用寿命。In this paper.the development of type-O rubber sealing rings used in a liquid pressure system of air-borne radar and its key techniques are described. Compared with uncov ered rings,the sealing rings covered by PTFE film have the features of lower friction coefficient,less loss coefficient and better sealing function. The reliability and life-time of sealing rings is improved.
