Passively and Actively Controlled Externally Pressurized Oil-Film Bearings
Journal of Lubrication Technology, 1972The first section of this paper is concerned with the description of a hydrostatic bearing when compensated by passive orifice or capillary type restrictor. In the second section a survey of the various types of active restrictors is outlined. Active restrictors considered include the constant flow valve, integral control valve, diaphragm controlled ...

Oil Film Thickness and Pressure Distribution in Elastohydrodynamic Point Contacts
Journal of Mechanical Engineering Science, 1982In this paper, a general numerical solution to the elastohydrodynamic point contact problem is presented for moderate loads and material parameters. Isobars, contours and regression formulae describe how pressure and oil film thickness vary with geometry, material properties, load, and squeeze velocity, when the rolling velocity vector is at various ...

Measurement of Piston Skirt Oil-film Pressure under Piston Slap
SAE Technical Paper Series, 2007<div class="htmlview paragraph">Using small thin-film pressure sensors deposited onto a piston skirt surface, oil-film pressure on the piston skirt surface is measured when piston slap noise is generated without affecting the surface geometry, stiffness and mass of the piston.

Fiber Bragg Grating-Based Oil-Film Pressure Measurement in Journal Bearings
IEEE Transactions on Instrumentation and Measurement, 2019The on-line measurement of oil-film pressure inside a journal bearing based on an optical fiber Bragg grating (FBG) is proposed and described for the first time. Two methods are described, one includes inserting the packaged FBG into the bearing using rubber and the other is involved the packaged FBG being directly embedded on the bearing surface.

Pneumatic Impact Ignition of Sebum Oil Film in High-Pressure Oxygen
Journal of ASTM International, 2006Abstract Whenever oxygen systems are assembled or maintained, a risk of introducing contamination arises. Potential contaminants include oils from a person's hands and body left behind in the form of fingerprints. The oil on the surface of skin is a complex mixture of sebum oil, lipids, sweat, and environmental materials.

Transducers for pressure, temperature and oil film thickness measurement in bearings
Sensors and Actuators, 1982Abstract Thin-film manganin pressure transducers have been developed for in situ pressure measurement in lubricated contacts. They are sufficiently small to allow resolution of the pressure spike, predicted by EHL theory. In addition, a resistance transducer for the simultaneous measurement of temperature and a capacitive transducer for the ...

Optical sensor for oil film pressure measurement in journal bearings
2008In operation of journal bearings, the oil film pressure is one of the key parameters. Until now, measuring of the oil film pressure has been a demanding or even unfeasible task, especially in journal bearings carrying dynamic loads. A new approach that has been developed for experimental determination of the oil film pressure is based on optical ...
