Effect of surface texturing on hydrodynamic lubrication at various temperatures
Source abstract
Abstract
The formation of hydrodynamic lubrication is analyzed based on an experimental study of the hydrodynamic lubrication characteristics between two parallel surfaces with different types of surface texturing. The study considers planar samples of C45 steel and accounts for the thermal expansion of 304 stainless steel in the experimental apparatus at oil temperatures of 323.15 K and 353.15 K. The experiments involve the use of a rotating rheometer at various angular speeds, with the effect of thermal expansion that occurs in actual applications being simulated by varying the gap between the planar sample surfaces. The experimental results show that (i) the lubrication properties of the planar textured samples depend strongly on temperature and (ii) the load-carrying capacity of the textured samples is considerably greater than that of the non-textured samples.
