摘　　要：介绍了一种新型的液压-螺旋拔轴器的结构、工作原理和特点。该结构具有螺旋和液压两级增力,用手动的方法就可以达到1 000 kN^2 000 kN的作用力。采用大螺杆进行行程补偿,具有结构紧凑,质量轻,易操作等特点。该结构适用于大型旋转设备,也可以在小批量、小压制行程的锻压机械和工程施工专用设备中推广。The structure, working principle and characteristics of a kind of novel hydraulic-screw axle-puller were introduced. Its structure possesses two-staged force enhancement of screw and hydraulic pressure, just the hand moving method can reach an effort of 1 000 kN～2 000 kN. By adopting the big screw that has the characteristics of compact structure, light masses and easy manipulation to carrying out travel compensation. This structure is suitable to be applied to large rotation devices, and could be popularized as well as in forging machinery of small series production with small pressing stroke and in the special purposed device of project construction.
