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.

Method of making a plain bearing shell

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 may be formed on a part of the thickness of the outer part of the bearing by radial shaping of the material. This may be made on the joint face of bearing liners or one 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.

Plain bearing

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. The liner is of uniform radial thickness at least between the channels. Lubricant is withdrawn from the channels to maintain the contact area substantially dry.

Plain journal bearing

A multi-layered plain slide bearing having a metal base layer, and having a slide layer which is carried by the base layer and which comprises a copper-lead-tin binary or ternary alloy that has been applied to the base layer and that has an unusually high cooper content. The slide layer can contain, by weight, from 20% to 70% of copper, at least 15% and at the most 80% of lead, and from 0% to 30% of tin, and can also optionally contain indium, cadmium or other like metals. The slide bearing can further include a run-in layer which covers the slide layer, and which contains copper, tin, indium and/or lead or their oxides, sulfides or phosphides.

Plain bearing laminate having slide-layer alloy based on copper-lead-tin

A composite bearing comprising a backing layer, an intermediate layer of a good heat conducting, medium modulus of elasticity metal on said backing layer having a Vickers Hardness (Diamond Pyramid Hardness) in the range between approximately 30 [kp/mm.sup.2 ] and 100 [kp/mm.sup.2 ] and a thickness in the range between approximately 0.2 and 0.7 mm (0.001 and 0.03 inch). A first bearing layer is provided as the main surface layer on said intermediate layer having a thickness of more than 0.0025 mm (0.0001 inch) and not more than 0.1 mm (0.004 inch) preferably in the range between 0.003 mm to 0.01 mm (0.00012 to 0.0004 inch) and consisting of a bearing metal having a Vickers hardness (Diamond Pyramid Hardness) of at least 200 [kp/mm.sup.2 ]. An additional surface layer is provided over said first bearing layer as a running-in layer having a thickness of not more than 0.05 mm (0.002 inch) and consisting of a bearing metal alloy having a Vickers hardness (Diamond Pyramid Hardness) in the range between approximately 4 [kp/mm.sup.2 ] and 30 [kp/mm.sup.2 ].

Sliding friction bearings

A sliding bearing has a pocket recessed into the bearing surface and an edge of the pocket over which oil is supplied to the bearing surface is in the form of a wavy sinuous or sharper sawtooth-like line, with the discharge points being indentations extending in the direction of motion of the component supported for sliding on the bearing surface.
