摘　　要：液压支架推移千斤顶不同于其他部位千斤顶,主要区别是推移千斤顶带有较长的耳轴,在实际生产使用中,由于地质条件及采煤工况的变化,导致耳轴两侧出现受力不均衡的状况,产生较大的扭转力矩,这种状况下对推移千斤顶的强度和刚度,以及千斤顶导向环和密封件的寿命都会产生一定的影响。本文着重讨论偏心量的计算及对导向环的影响。The advancing jack in hydraulic support is different from others in other parts, and the main difference is that the advancing jack has long trunnion. In actual production and use, the changes of geological conditions and mining conditions always lead to the unbalanced stress condition and generate large torque. This situation will influence the strength and stiffness of advancing jack rider ring and influence the life of the seal. This paper mainly discusses the calculation of eccentricity and influence on rider ring.
