摘　　要：针对气浮轴承供气管对气浮装置具有扰动作用而产生附加作用力,设计了一种无气管扰动气浮轴承结构,并详细介绍了其工作原理.迷宫密封是该结构的关键部分,根据迷宫密封参数与气体泄漏量之间的数学关系,对迷宫密封进行了流体动力学仿真,并与理论计算结果进行对比.研究结果表明:仿真结果和理论数值计算结果具有较高的一致性,得到的最佳迷宫密封结构在项目实验中得到很好的运用.On the purpose of eliminating additional force of air supply pipe to gas bearing, a new structure of gas bearing without influence of air supply pipe was put forward, and its basic structure and working principle was introduced. Based on the relation of labyrinth seal parameters and gas bearing leakage, simulation of important component labyrinth seal was carries out to compare with theoretical calculation. Research result indicates high consistency between simulation result and theoretical calculation. Finally the best structure of labyrinth seal is well applied into project experiment.
