The invention relates to a tool for machining sliding surfaces of a bearing shell (), comprising a rotary drive for driving a drilling spindle () that can be rotated about a rotational axis and at least one first cutting cartridge that is mounted on the drilling spindle () in order to cut the bearing shell () to a certain wall thickness by rotating the drilling spindle (). The tool is characterized in that the first cutting cartridge can be adjusted by an adjustment means in a direction of adjustment that has a component in the radial direction of the drilling spindle, while the drilling spindle () is rotated by the rotary drive. The invention further relates to a bearing shell () comprising a deliberately structured sliding surface () and to a method for producing a bearing shell () comprising a deliberately structured sliding surface ().

Structured sliding surface of a bearing shell

A plain bearing shell includes a slide face of which, in the region of the apex of the plain bearing shell, is convexly curved in the axial direction at least at the edge regions, wherein the curvature is at its most pronounced at the apex of the plain bearing shell and decreases continuously in the circumferential direction of the plain bearing shell toward the two partial surfaces. A method for producing such a plain bearing shell is also provided.
