5. Conclusion
The bush temperature for the offset-halves journal bearing has been obtained by evaluating the oil-film
temperature using parabolic temperature profile approximation technique. It has been observed during the
analysis that a considerable amount of heat flows through the bearing material in addition o the flow of heat
with the lubricating oil used for hydrodynamic action. Further, it can be seen from the discussion that the
eccentricity ratio and speed of journal influences the amount of temperature rise in bush material. Hence, it can
be concluded that care of bush temperature parameter should be taken into consideration while designing such
kind of journal bearing profiles.
