A method for manufacturing a sliding layer of a slide bearing includes applying any of the following alloys and/or materials, namely SnSb8Cu4, SnSb12Cu6Zn, CuSn12Ni2, CuAl10Fe1, tin and aluminum bronzes, aluminum materials and alloys made therefrom, to a base body in a laser-based application process, wherein the alloy and/or material for application is in the form of a powder or compacted powder or as a wire.

A wind turbine gearbox, in particular planetary gearbox, has at least one gear which is mounted on an axle, wherein a sliding surface is arranged between the gear and the axle. The sliding surface is arranged on at least one layer of a deposition welded material made from a sliding bearing material. Furthermore, a method produces the wind turbine gearbox.

A metal foam ball, several millimeters in diameter, is manufactured to have an open-pore structure to absorb fluid (e.g., gas and liquid) such as water or lubricant. As an example, a copper foam ball is manufactured via a freeze casting method using prepared oxide powder slurry where a spherical silica gel mold is used to freeze the slurry, which is subsequently dried at low temperature in vacuum and then sintered at high temperature. For improved oxidation, copper alloy foam ball or copper foam ball coated with tin can also be manufactured through the same method. For improved strength, steel, copper-nickel alloy, or titanium foam ball can also be manufactured through the same method.

A Plain bearing having an outer ring and an inner ring, the outer ring and the inner ring providing respectively an inner surface and an outer surface intended to cooperate with each other for the relative movement of the outer and inner rings, the inner surface of the outer ring and the outer surface of the inner ring each including a coating including at least one layer. The hardness of the coating on the inner surface of the outer ring is less than the hardness of the outer ring, and the hardness of the coating on the outer surface of the inner ring is greater than the hardness of the inner ring.

A wind turbine gearbox, in particular planetary gearbox, has at least one gear which is mounted on an axle, wherein a sliding surface is arranged between the gear and the axle. The sliding surface is arranged on at least one layer of a deposition welded material made from a sliding bearing material. Furthermore, a method produces the wind turbine gearbox.

A planetary transmission for a wind turbine includes a bolt having a cylindrical outer surface and a gear having a cylindrical inner surface rotatably supported on the outer surface of the bolt. The cylindrical outer surface of the bolt and the cylindrical inner surface of the gear are configured to function as a plain bearing, and one or both of these surfaces may include a sliding layer formed from a low friction material.

Disclosed herein a bearing that comprises a base, made of a metallic base material. The base comprises a cylindrical outer surface, a cylindrical inner surface that is opposite the cylindrical outer surface, and a central channel defined by the cylindrical inner surface and extending through the base. The bearing also comprises a selective transfer material embedded in the base. The selective transfer material is different than the metallic base material and is configured to release from the base in response to frictionally-induced pressure acting on the base.
