Title:
PARTIAL STRUCTURING OF SLIDING SURFACES
Document Type and Number:
WIPO Patent Application WO/2013/182539
Kind Code:
A3
Abstract:
When structuring the sliding bearing surfaces (1) of a crankshaft by selectively introduced, microscopically small depressions (27), to achieve a great reduction in friction during use of the crankshaft with little effort, it is proposed in the case of centre bearings and pin bearings to structure specifically only the regions of the bearing surface that are subjected to high levels of loading, both in the circumferential direction and in the axial direction, since even these are difficult to reach in view of the working gap from the tool of only a few microns.
