Abstract: In a laminate for friction bearing elements which contains, on a metallic support layer, an anti-friction layer comprising an aluminum alloy containing nickel, manganese and lead, there is additionally provided bismuth or copper which improve considerably the bearing properties and also facilitate the surface machining by chip removal of the anti-friction layer. It is of particular advantage if the aluminum alloy has the addition of both bismuth and copper, resulting in considerably improved sliding characteristics and improved emergency running properties in addition to substantially improved properties regarding strength, dynamic loadability, fatigue strength and good machinability.

Abstract: Method and machine for producing friction bearing shells from ribbon-shaped composite laminate material, wherein the composite laminate material is fed and processed in successive stages at a multiplicity of successive stations until the shells are finished, except for the slide surface processing. The continuous processing includes chip-generating operations arranged to considerably improve the precision and quality of the friction bearing shells that are produced. The ribbon is blanked to produce individual plates which are disposed transverse to the transport direction, making it possible to work on each individual plate without reaction upon other plates. Scrap and chips are removed, preferably at spacing areas. The shells leaving the continuous production line are finished, except for any processing of the slide surfaces.

Abstract: Plain bearings, particularly thin-walled plain bearing liners, are provided with radial projections for fixing and as an aid to assembly, e.g. with lugs, on the outer side of the outer part of the bearing, without using the whole thickness of the outer part of the bearing, so that the inner surface of the outer part of the bearing, which carries the functional layer, remains along its whole length cylindrically curved and smooth. Such outer projections are formed on a part of the thickness of the outer part of the bearing by radial shaping of the material. This is made on the joint face of bearing liners or on one or the other of the axial end faces of bearing liners or bushes or also on any desired place of the outer peripheral surface of the outer part of the bearing.

Abstract: A composite structural material particularly intended for frictional and slide elements, consisting of a substrate such as a steel layer with a copper- or tin-containing intermediate layer, a tin- or copper-containing functional layer and, between these last two layers, a diffusion barrier layer protecting against diffusion of tin from the functional layer into the intermediate layer or back to the diffusion barrier layer. The diffusion barrier layer consists of a metallic material having a hexagonal crystal lattice, which material is applied by cathodic sputtering, forming a material structure that is densely packed in vacuo with a space filling by metal ions of above 70%. For the cathodic sputtering, conditions of plasma pressure and substrate temperature can be chosen so that recrystallization occurs simultaneously with the formation of the diffusion barrier layer; this makes it possible to achieve the densest hexagonal packing, with a space filling of up to 74%.

Abstract: A slider bearing assembly has a bearing housing having a bore centered on an axis and having an inside bore surface and a uniform composition plain bearing liner in and coaxial with the bore and having an outer surface delimited by two axially oppositely directed end faces, an axial middle region between the end faces, and an inner surface centered on the axis. The bore and outer surfaces are in mutual surface contact in a contact area and normally directly engage each other without the interposition of a liquid lubricant. The bearing liner is fixed in the housing against any movement relative thereto other than micromovements. A movable part has a journal centered on the axis and radially outwardly confronting and normally engaging the inner liner surface. This movable part is nonradially movable relative to the liner and housing, that is it can only move axially and/or angularly relative to the liner. Drainage channels formed in at least one of the surfaces at the contact area extend to the axial end faces.

Abstract: In a sliding bearing, a metallic layer is coated on a bearing base bush and is provided with grooved or helical or crossing indentations with intermediate elevations. Applied in a uniform manner onto the so-formed metallic layer is a sliding layer of softer material. Under pressure or application of shear forces, the material of the sliding layer provided above the elevations is forced through plastic shaping to flow into the indentations so as to provide a levelled and smooth sliding surface covering the metallic layer.

Abstract: The bearing is composed of a strong metallic backing, a softer metallic support layer, and a galvanically applied metallic anti-friction layer, the support layer and the anti-friction layer being of mutually different metals or metallic alloys. An intermediate layer is provided between the support layer and the anti-friction layer. The intermediate layer is made as a layer which prevents or limits diffusion of metallic components from the anti-friction layer into the supporting layer and vice versa, and is composed of a binding layer, entering into a lasting surface bond with the material of the anti-friction layer, and of an underlayer, entering into a lasting surface bond with the material of the support layer.

K. above the melting temperature of the synthetic resin.

Abstract: Laminated anti-friction bearing material and process for producing the same. Heterogeneous wire, containing both metallic and non-metallic elements or components, is atomized by an electric current impulse discharge which causes an explosive or sputtering disintegration of the wire, resulting in the materials thereof being sprayed or deposited onto a substrate. The deposited coating can include a matrix formation in its make-up, with discrete anti-friction and other particles, and is characterized by a strong cohesion to the substrate, together with highly desirable sliding properties. The sputtering is accompanied by a controlled oxiding, or a controlled sulfidizing of the sputtered materials, and the sputtering can produce an improved anti-friction layer, and also an improved running-in layer.
