Abstract
The invention pertains to a plain porous bearing for motors and transmissions with a circular bearing bore that displays, distributed alternatingly across the bearing bore, highly compressed at least approximately closed-pore areas and slightly compressed, open-pore areas, where the bearing bore diameters of the highly and slightly compressed areas are at least approximately identical. Also provided is a procedure and device for production of the bearing.
Claims4
A porous plain bearing for motors and transmissions, the bearing having a circular bearing bore that includes alternatingly distributed (i) highly compressed generally closed-pore areas, and (ii) slightly compressed open-pore areas, the bearing bore diameter at the highly compressed areas is at least approximately equal to the bearing bore diameter at the slightly compressed areas, wherein the compression about the circumference of the bearing bore between the highly and slightly compressed areas is continuously varied such that the bearing bore has a non-linear density gradient.
