Abstract
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.

A plain bearing shell, having a slide face of which, in the region of apex of the plain bearing shell, the slide face is convexly curved in an axial direction of the bearing shell at least at the edge regions of the slide face;
- and
- wherein the convex curvature is most pronounced at the apex of the plain bearing shell and decreases continuously in the circumferential direction of the plain bearing shell toward two partial end surfaces of the bearing shell.
A method for producing a plain bearing shell using a rotating drill spindle, comprising the following steps:
- a) clamping a bearing shell blank in a holding fixture for drilling;
- b) overlapping a relative, linear movement of the bearing shell blank and the drill spindle along the axial direction of the plain bearing shell to be produced for finish-drilling a slide face of the plain bearing shell with a relative movement perpendicular thereto of the bearing shell blank and the drill spindle such that a plain bearing shell having a round slide face is produced.
