Method for producing bearing shells of plain bearings

摘要

The present invention relates to a method for producing bearing shells of plain bearings, in which the bearing shells are blasted with corundum particles on the bearing metal side, in order in this way to produce residual compressive stresses in the blasted side of the bearing shell. Furthermore, the present invention relates to a bearing shell produced using such a method.

主权项

1. A method for treating a bearing shell of a plain bearing, in which the bearing shell is blasted with corundum particles on a concave surface of the bearing shell, wherein the concave surface is at an inner side of the bearing shell, so as to generate compressive residual stresses on the inner side of the bearing shell, wherein the inner side of the bearing shell is compressed by the impact of the corundum particles, the bearing shell further includes an unblasted surface, and the blasted surface has a blast-induced increased hardness that is more than 10% greater than the hardness of the unblasted surface.
