Abstract
This thesis studies the design process of the hydrostatic bearing, and completes a horizontal hydrostatic rotary bearing design with high performance based on a properly structural design and with self-made capillary restrictors. In theory, analyze the flow resistance of the pad and restrictors to design the pressure ratio between the source and the pocket, which conduces to design the bearing stiffness. Secondly, this study probes the function of the load capacity of the single pad and the opposed pad hydrostatic bearing, and the performance of stiffness. In addition, this work also searches the relevant literature about the computation of the stiffness and the load capacity to obtain the essential parameter which influences the bearing’s characteristics, such as the oil film thickness, the land dimension, the oil viscosity, the total flow. This work will compare and analyze the experimental results and the functions about different literatures to estimate the performance of the bearing accurately. This thesis uses the existing horizontal hydrostatic bearing to do the experiment and analyze before the design contracts out. These experimental results compare the actual performance with the theoretic performance to make discussion about the probable parameter of error and present a method to improve the performance of the horizontal hydrostatic rotary bearing. Key words: horizontal hydrostatic rotary bearing, restrictor, stiffness
