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.

The invention relates to an anti-friction lacquer having a polymer as a resin matrix and functional fillers, the functional fillers containing mixed-phase oxides and optionally further functional fillers. The invention further relates to a sliding element having a metallic substrate layer and a coating which is applied thereon and made of at least such an anti-friction lacquer and to a method for the production thereof.

A bearing including a backing formed of a steel material, a lining formed of aluminum or an aluminum alloy, and a diffusion barrier layer disposed between the backing and the lining is provided. The diffusion barrier layer is formed of nickel or a nickel alloy and has a thickness ranging from 1 micron to 100 microns. The bearing is typically formed by cladding the lining or plating the steel backing with the diffusion barrier layer, bonding the lining and the backing with the diffusion barrier layer between, heating to a temperature of at least 400° C., and forming the bearing into a shape after or before the heating step.

A fluid film bearing includes a plurality of bearing pads that are arranged in a circumferential direction of a rotating body that rotates about an axis, and that support the rotating body via a fluid film, wherein the bearing pad includes a base layer made of metal, an elastic layer that is layered on the rotating body side of the base layer, and that is made of an elastically deformable elastic material, a sliding layer that is layered on the rotating body side of the elastic layer, and that opposes the rotating body and is made of a bearing material, and a metal plate that is layered between the elastic layer and the sliding layer, and that is more rigid than the elastic layer and the sliding layer.

A plain bearing, having a bearing base body made from a metallic material, having an intermediate layer made from a metallic material applied onto the bearing base body, and having a plain-bearing layer made from a non-metallic material applied onto the intermediate layer. The intermediate layer is an arrangement of wires or a perforated plate. The arrangement of wires or the perforated plate forms undercuts and the plain-bearing layer is a layer made from polyether ether ketone.

An anti-friction lacquer has a resin matrix of a polymer and functional fillers containing mixed-phase oxides having a specified grinding hardness and proportion and optionally contain further functional fillers. A sliding element is also disclosed having a metallic substrate layer and a coating applied to the substrate that is made of at least in part of the anti-friction.

A sliding-hearing composite material includes a steel supporting layer (10), an intermediate layer (12) based on an aluminum alloy that is free of lead, and a bearing metal layer (14) based on an aluminum alloy that is free of lead, wherein the aluminum alloy of the intermediate layer (12) has a composition having 3.5 to 4.5 wt % copper, 0.1 to 1.5 wt % manganese, 0.1 to 1.5 wt % magnesium, and the usual admissible impurities, the remainder being aluminum, and wherein the aluminum alloy of the bearing mental layer (14) has a composition having wt % tin, 1.0-3.0 wt % nickel, 0.5-1.0 wt % manganese, 0.5-1.0 wt % copper, 0.15-0.25 wt % chromium, 0.1-0.3 wt % vanadium, and the usual admissible impurities, he remainder being aluminum. A sliding bearing element and the use of the sliding-bearing composite material for sliding bearing element, particularly sliding bearing shells, sliding bearing bushes, or thrust washers is also disclosed.

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.

[Object] Provided is a technique capable of reducing the possibility of generation of a Cu—Sb compound in an overlay and the possibility of delamination between layers.

[Solution] A sliding member includes: an overlay including an alloy plating film of Bi and Sb; a lining including an Al alloy; a first intermediate layer including Cu as a main component, and laminated on the lining; and a second intermediate layer including Ag as a main component, and connecting the first intermediate layer and the overlay.
