摘　　要：为提高纠斜液压缸的密封性能,设计了两种组合密封圈,研究其在不同液压油压力及液压油与泥浆压差下的等效应力、接触应力和摩擦力,并进行模拟实验。结果表明:随着钻探深度的增加,YR和WR形密封圈的最大等效应力、最大接触应力和摩擦力逐渐增大,但YR形密封圈的数值相对较小,接触应力分布相对均匀;压力补偿油箱内外压差对密封圈的性能影响较小,设计使用中可忽略;YR形密封圈的密封性能相对较好。To enhance the sealing performance of the hydraulic cylinder,there are design two types of combined sealing rings.These rings were examined under various hydraulic oil pressures and pressure differences between the hydraulic oil and mud,and simulation experiments were conducted.The findings indicate that as the drilling depth increases,the WR and YR seals experience a gradual rise in maximum equivalent stress,maximum contact stress,and friction.However,the YR seals demonstrate relatively smaller values,along with a more uniform distribution of contact stress.The impact of pressure difference between the internal and external compartments of the pressure compensation tank on the seal ring's performance is negligible and can be disregarded during design and usage.Overall,the YR sealing ring exhibits comparatively superior sealing performance.
