Accurate dimensional characterization of the textured inner surface of the bearing bushing by the mean of a new measurement instrument
Abstract
The measurement of dimples created on the inner bushing surface is a key step in the quality assessment of the textured bearings, because of their substantial effect on the bearing performance. The aim of this study was the complex analysis of the surface topography of textured inner bushing surface with application of the newly designed and built instrument for 360 degrees surface topography measurements. In the article the theoretical models of different textures of the inner bushing surface were analyzed. The influence of spherical dimples: depth, diameter, surface, volume and coverage on the important geometrical parameters describing journal bearings that effect on bearing performance significantly was presented. The effective bearing clearance of textured journal bearing obtained from the model and experiment were in good agreement and differed insignificantly. The differences between values of the theoretical and measured parameters of dimples were very small − approximately 1.2% for dimple depth and 2.6% for dimple volume. The main advantage of the new instrument is the capability of the accurate and precise measurement of inner textured surface of bushing without limitation to just selected zones and without the necessity for destructive testing.
