摘要
石墨封严环在机械关键部件密封中有着重要作用。以直升机传动系统为研究对象,分析了石墨封严的同轴度、摩擦功率对泄漏失效的影响,并提出了石墨封严环泄漏失效的预防措施。
Graphite sealing rings play an important role in the sealing of key mechanical parts. Taking the helicopter transmission system as the research object, the influence of the coaxiality and friction power of graphite seal on the leakage failure is analyzed, and the preventive measures for the leakage failure of the graphite seal ring are proposed.
