摘　　要：针对液体火箭发动机涡轮泵特殊工作环境,讨论了流体动静压轴承可采用的结构形式和需要解决的关键技术。提出了径向轴承宜采用腔式结构,止推轴承宜采用螺旋槽或瓦块结构;并针对液氧涡轮泵动静压轴承提出了研究需要解决的关键技术。This paper mainly discusses available structures of the liquid hybrid bearings and the key technologies that need to be solved for the liquid rocket engine turbopump.It was suitable for radial hybrid bearing to adopt column bearing,and for axial bearing to adopt spiral groove bearing or tiling bearing under the special environment of liquid rocket engine turbopump.At the end of this paper,some key technologies about oxygen hybrid bearing application in the engine turbopump are proposed.
