Thrust dynamic pressure gas bearing of elastic support structure

The invention discloses a thrust dynamic pressure gas bearing of an elastic support structure. The gas bearing comprises a first foil piece, a second foil piece, a third foil piece and a fourth foil piece, wherein the first foil piece, the second foil piece, the third foil piece and the fourth foil piece are sequentially stacked and installed on a bearing installation base through a positioning hole. According to the gas bearing, the welding process can be avoided, stable lubricating and supporting effects are maintained through the laminated structure, the reliability of the bearing is improved, and the service life of the bearing is prolonged. 本发明公开了一种弹性支撑结构的推力动压气体轴承，包括第一箔片、第二箔片、第三箔片和第四箔片；第一箔片、第二箔片、第三箔片和第四箔片依次通过定位孔叠放安装在轴承安装座，本发明能够避免焊接工艺，通过叠片式的结构维持稳定的润滑与支撑作用，增进轴承的可靠度及使用寿命。
