A Review of Hydrostatic Bearing: Research and Analysis

Background: As a kind of sliding bearing with liquid as a lubricant, Hydrostatic journal bearing can be shown from tribology, mechanics, optimization method and structural design in engineering practice. Hydrostatic bearing characterized by high precision, high rigidity, and long life has drawn people's attention and been widely adopted. As progress has been made in science and technology, people will have a better understanding of the principles and characteristics of the hydrostatic journal bearing. Objective: The development of hydrostatic bearing in recent years is studied and analyzed. Methods: More than 70 recently published patents and journal and conference papers related to the developments in air traffic flow management are reviewed, and the outcomes in temperature field, pressure field, deformation, lubrication, bearing capacity and friction are studied. Results: Through these research results, the current research status of hydrostatic bearings is summarized, and the three aspects of flow field characteristics, lubrication characteristics and tribology are explained, and solutions and feasibility measures for existing outstanding problems in each aspect are mentioned. Conclusion: Based on this article, the design and optimization of hydrostatic bearings are of guiding significance. Finally, the current problems and challenges of hydrostatic bearings are analyzed, and future research directions and research priorities are prospected.
