Abstract: In order to study the effect of micro-texture size on the friction and wear characteristics of journal bearing,
using the theoretical model of friction and wear of journal bearing and the method of friction experiments, the rule of
friction and wear performance with different micro-texture sizes was analyzed. The results showed that with the increase
of micro-texture size, the lubrication performance of the journal bearing increased firstly and then decreased in the
√
theoretical model of friction and wear. The optimal lubrication performance occurred at the dimensionless radius of 2.
With the increase of micro-texture depth, the wear performance of the journal bearing decreased firstly and then
increased. When the dimensionless depth was 0.03, the journal bearing had the best wear performance. When the micro-
√ √
texture radius was 4 and 5 , the wear was low. In the friction experiment, the lubricating performance was the best as
the micro-texture radius was 0.17mm, and the average friction coefficient was 7.1% lower than that for the micro-texture
radius of 0.1mm. And the surface morphology wear was significantly smaller than other sizes pieces. Both theory and
experiment proved that proper micro-texture size improved effectively the lubrication performance, reduced the friction
coefficient and the wear of journal bearings.
