探讨将应用于抽水蓄能电站发电机组中的新型可逆式动压推力轴承结 构，即采用改变摆动瓦两侧波纹管压力差和支承摆动瓦的球面油垫的压力 分布以实现压力中心可调的侧推轴承结构．应用有限元法对二维Ｒｅｙｎｏｌｄｓ 方程进行求解计算，从而求出这种新型推力轴承的油膜压力和油膜厚度分 布，找出了在ｈｍｉｎ＝Ｃ时的最佳油楔角及与之对应的最大承载能力，并对这 种轴承的参数进行实验验证． In this paper, a new type of reversible hydrodynamic thrust bearing structure to be applied to the generator set of pumped storage power station is adopted, that is, the pressure distribution of the spherical oil pad is adjustable by changing the pressure difference of the bellows on both sides of the swinging tile and supporting the swinging tile Side thrust bearing structure. The two-dimensional Reynolds equation is solved by finite element method to get the oil film pressure and oil film thickness distribution of this new type of thrust bearing. The optimal oil wedge angle at hmin = C and its corresponding maximum bearing capacity Ability, and experimental verification of the parameters of this bearing.
