Studying, designing and manufacturing the lubrication system control for hydrodynamics journal bearings with variable load and variable speed

Abstract

This paper presents a study in designing and manufacturing the lubrication
systemcontrol for hydrodynamics journal bearings. The object of study are
hydrodynamics journal bearings with the load on the bearing, while the
center of the shaft is fixed by roller bearings. The load can be changed
(from 400 to 700) N and the speed of shaft varies (from 600 to 1400) rpm.
The article also presents the manufacturing of a lubrication system for
hydrodynamics journal bearings, establishing a microcontroller schematic
based on an ATmega328 microprocessor and the signal of the
pressure/temperature sensor installed in the slick. The display software for
such system was created by MATLAB programming software. The results
also showed that the lubricant consumption can be changed accurately
with the variation of load and speed.
