A review of the design and optimization of large-scale hydrostatic bearing systems

Abstract

In the last decades, the demand for hydrostatic bearings application has been rising due to the possibilities and advantages they offer. The advancements in hydrostatic lubrication understanding and computer technology improvement opened new ways for hydrostatic bearing performance and precision improvement. The emergence of the trend Industry 4.0 has brought new challenges and opportunities to the heavy machinery industry. This paper reviews the overall design and optimization processes for large-scale hydrostatic bearing geometry including the hydraulic system. The latest developments in the bearing geometry optimization, pressurized fluid supply components, and flow control devices are discussed. Moreover, possible measures for avoiding costly maintenance and repairs of the hydrostatic bearing are proposed. Finally, potential future research directions in large-scale hydrostatic bearing development are suggested. This review offers a comprehensive summary of potential problems and possible solutions in the large-scale hydrostatic bearing design, and simultaneously, serves as a supporting material to overcome potential obstacles that might emerge during manufacturing, assembly, and service.
