Abstract

A cooling and lubricating arrangement of tribological contact areas is disclosed. The arrangement includes tribological contact areas that slide over one another, of which at least one contact area has a surface contour with surface depressions in which a lubricant is stored. The surface contour forms a number of elongate grooves, the gap heights of which, at least in respect of respectively two adjacent grooves, are preferably different.
