In order to improve the friction and wear performance of textured port plate pair, effects of the micropit depth on the tribology\nperformance is studied in the paper. The relation between the micropit depth and the port plate pairâ??s oil loading carrying capacity\nis analyzed in theory; with the friction coefficient, the wear volume and the surface roughness as the evaluation criteria, effects of\nthe micropitsâ?? depth on the tribology performance are investigated. The conclusions are shown as follows: oil loading capacity\nwould come to its peak when the oil film thickness is equal to the micropit depth; the optimal micropit depth is unrelated to the\narea ratios and micropitsâ?? diameters. With the same parameters, the effects of antifriction is optimal when the micropitsâ?? depth is...........
