Aerostatic bearings are the core parts of ultra-high-speed spindles with maximum running speed greater than 100,000 r/min. In this paper, the influences of herringbone grooves on the performance of aerostatic journal bearings are studied to design spindles with the features of higher precision and higher speed. Parametric studies and sensitivity analyses are executed in terms of the improved finite element method, which is specially developed to solve the compressible Reynolds equation for herringbone grooved air bearings. The calculated results indicate that herringbone grooves significantly improve the performance of aerostatic journal bearings under the conditions of ultra-high speeds and low supply pressures. Groove parameters are nonlinear dependent, and groove depth and length are the dominant influential factors for the load capacity at speed of 200,000 r/min. Experiments are designed and conducted to verify the improved finite element method, which show that the improved finite element method can be used to analyze the influences of herringbone grooves on aerostatic journal bearings and also manifest that suitable herringbone groove geometrical parameters can obviously decrease spindle radial runouts at ultra-high speeds.

This paper discusses the stability of herringbone-grooved aerodynamic journal bearings supported by rubber O-rings. In this research, the dynamic stiffness and the damping properties of the O-rings are identified in a variety of operating and design conditions. The identification results are fitted with the empirical formulae previously proposed, and the distributions of the dynamic properties in a variety of support conditions are obtained. It is theoretically investigated how the stability of the bearing system changes with the dynamic properties. The bearing tests are also performed to verify the analytical results with the empirical formulae. The empirical formulae used here was reasonable for simulating the dynamic properties of the O-rings in a variety of bearing support conditions. The comparisons between the analysis and experiments verified the effectively of analyzing the stability of the bearing system by using the empirical formulae.

“…Analyzed film lubrication of Herringbone grooves by two-dimensional that ignored the narrow groove theory shown that light-load herringbone groove lubricating bearings had better stable. The research on herringbone groove lubricating bearing's parameters effected on the characteristics of lubrication and rotor dynamic, shown that pressure distributed widely along the circumference and the rotor had higher stable [6,7]. This paper numerical analysis [8] of herringbone groove hydrodynamic lubricating bearing based on Reynolds equation [9], obtained the high speed and small herringbone groove hydrodynamic lubricating bearing's relationship between load, rotational speed and eccentricity, temperature rise which provided evidences for application.…”

In this paper, numerical analysis of the high speed and small herringbone groove hydrodynamic lubricating bearing's bearing capacity,rotational speed effected on the bearing's eccentricity ratio and temperature rise, film thickness,oil film pressure distribution was solving by Reynolds equation under the Reynolds boundary condition, temperature rise was solving by Reynolds equation. The results shown that the temperature of bearing decreased first, then increased with eccentricity increasing, eccentricity ratio increased with bearing's load increasing but decreased with journal's rotational speed increasing, compared to normal sliding bearing, herringbone groove hydrodynamic lubricating bearings had higher stability and bearing capacity.
