The Measurement of Oil-Film Thickness in Gear Teeth

Journal of Basic Engineering, 1960
The voltage drop across thin oil films when a constant current of 1 amp is passed, i.e., the discharge voltage, is used to measure the oil-film thickness between loaded gear teeth while running. It is found that the thickness at the pitch line is between 1 and 4 × 10−4 in., which varies slightly with the viscosity and rather more strongly with load ...

Oil-Film Thickness in a Bearing of a Fired Engine

SAE Technical Paper Series, 1982
<div class="htmlview paragraph">Relative oil-film thickness has been measured in a main bearing of a fired, single-cylinder CLR engine. The bearing is electrically insulated from the block and a small voltage impressed between the bearing and crankshaft.

Nanometric Thickness EHL Oil Films

Part B: Magnetic Storage Tribology; Manufacturing/Metalworking Tribology; Nanotribology; Engineered Surfaces; Biotribology; Emerging Technologies; Special Symposia on Contact Mechanics; Special Symposium on Nanotribology, 2006
EHD oil films possess a remnant thickness of 10–20 nm at very low speeds. This behavior was justified numerically using an empirical equation for wall viscosity. This paper uses molecule-wall interaction potential and finds that the viscosity decreases exponentially with the distance to the wall. A thin attached layer, responsible for remnant oil film,

Interferometry-based measurements of oil-film thickness

Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2001
Measurement of the thickness of thin lubricant films separating rotating surfaces in elastohydrodynamic experiments presents some challenging problems. The nature of the experimental apparatus inhibits the use of most commonly applied interferometric phase measurement methods.

A study on variation in oil film thickness of a piston ring package: variation of oil film thickness in piston sliding direction

JSAE Review, 2000
Abstract This paper describes the variation in oil film thickness (OFT) of a piston-ring package measured with LIF on the piston thrust side in the sliding direction. It is found that the oil control ring OFT differs significantly from the theoretical value in the early stage of the down stroke.

Oil Film Thickness measurements in a Dynamically Loaded Journal Bearing—A Comparison of Measured and Calculated Minimum Oil Film Thickness with Newtonian Lubricating Oils

SAE Technical Paper Series, 1988
<div class="htmlview paragraph">As previously reported an experimental apparatus has been built that allows direct measurement of the oil film thickness in a bearing that is subjected to dynamic toads and shaft speeds representative of those occurring in automobile engine connecting-rod, big-end bearings.

Oil-Film Thickness in Rolling Bearings

2016
There are two kinds of lubrication for the bearings, oil and grease lubrications. In fact, the base oil dissolved in grease is separated from grease due to the centrifugal force of oil at increasing oil temperatures, and it is in fact used to lubricate the rolling bearings (cf. Chap. 5).

Analysis of Oil Film Thickness on a Piston Ring of Diesel Engine: Effect of Oil Film Temperature

Journal of Engineering for Gas Turbines and Power, 2001
This paper describes an analysis of oil film thickness on a piston ring of a diesel engine. The analysis of the oil film thickness has been performed by using Reynolds equation and unsteady, two-dimensional energy equation with heat generated from viscous dissipation.

Simultaneous monitoring of oil film thickness and temperature in fluid film bearings

Tribology International, 2001
This paper reports on the application of an eddy current sensor with an active compensation for changes in sensor temperature to simultaneous monitoring oil film thickness and temperature in a tilting pad thrust bearing. Sensor design, calibration procedure, sensitivity and accuracy are described.
