Investigation on influences of herringbone grooves for the aerostatic journal bearings applied to ultra-high-speed spindles

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2019
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 ...

Dynamically loaded journal bearings

1975
The aim of the work reported in this thesis was to develop a method, suitable for general design work, to determine the stability of a simple rotor mounted in hydrodynamic bearings, The rotor model used was a simple spring mass system, but the bearing model allowed a comprehensive range of bearing cross-sectional shapes and grooves to be assessed.

SELF‐OILED JOURNAL BEARINGS

Industrial Lubrication and Tribology, 1978
CERTAIN bearing applications require the use of a lubrication system contained within the bearing housing and independent of any outside systems or power sources. Marine main propulsion lineshaft bearings often fall into this category and the use of a disc‐scraper system for oil supply represents one solution.

The Magnetohydrodynamic Journal Bearing

Journal of Basic Engineering, 1963
An analysis of an infinite journal bearing is presented for the case of an electrically conducting fluid in the presence of a magnetic field. The magnetohydrodynamic form of Reynolds’ bearing equation is derived and solved for the pressure distribution. The load carrying capacity is determined from the pressure distribution.

Functioning of Journal Bearings

1969
When a journal bearing operates under conditions of hydrodynamic lubrication there is no contact between the rotating journal and the fixed bearing surface. In steady running the journal assumes an eccentric position, described as the journal attitude, in which the journal centre is displaced from the centre of curvature of the bearing surface in such ...
