根据流体力学有限元理论 ,对新型可逆式动压推力轴承承载能力作了计算。同时考虑了轴瓦的热变形的影响。建立了最小油膜厚度、油楔角与承载力的关系曲线。并与未考虑热变形的曲线作了比较。建议在实际调整最小油膜厚度时需增加该值的 13 %左右 ,用来补偿热变形。 According to the hydrodynamic finite element theory, the bearing capacity of the new reversible hydrodynamic thrust bearing was calculated. At the same time consider the impact of thermal deformation of the bearing. The minimum oil film thickness, oil wedge angle and bearing capacity curve were established. Compared with the curve without considering the thermal deformation, It is recommended to increase the minimum thickness of the actual film when the need to increase the value of about 13%, used to compensate for thermal deformation.
