The invention relates to a sliding bearing and to a method for producing a sliding bearing, having at least one groove formed on the sliding surface which extends at least partially in the axial direction of a mounted shaft, ends on at least one end before the edge of the bearing and is deeper than 80 &#x3bc;m and/or wider than 150 &#x3bc;m, so that dirt and/or particles can be embedded.

Structured dirt depository in sliding bearing surfaces

A plain bearing having a depository surface which has at least one depository and which is a sliding surface and/or a surface of an oil supply groove, wherein the depository is a cutout which is open in the direction of the depository surface and which has a depository a wall and which extends away from the depository surface into the bearing, wherein the depository wall, in the direction of extent, forms an acute angle with a reference direction, wherein the reference direction is the tangent to the depository surface at the point at which the depository wall intersects the depository surface in the direction away from the depository.

Dirt depositories in sliding bearings

A method and an apparatus for testing the adhesive strength of overlays attached to the inside of plain bearing bushings. The method is characterized in specifying clearance between the plain bearing bushing tested and a rotating or oscillating pin extending through the bushing. Next, feeding a liquid medium into the gap between the bushing and the pin and oscillating the plain bearing bushing and pin relative to one another perpendicularly to the bushing axis for a given period and examining the bushing after the load test. The corresponding apparatus comprises a pin mounted rotatably in a pin receptacle and on which there is arranged a first drive mechanism. In addition, a bushing receptacle is provided, in which the plain bearing bushing is fitted, wherein the pin is mounted with predetermined clearance in the bushing. The apparatus additionally comprises a mechanism for bringing about oscillating relative movement of bushing receptacle and pin receptacle.
