The invention relates to a rotor bearing system (). Said system comprises a housing () in which a first permanent magnet () is mounted such that it can rotate about a first axis (). A rotor () for conveying a liquid comprises a second hollow-cylindrical permanent magnet (), which is mounted such that it can rotate about a second axis. The first permanent magnet () and the second permanent magnet () overlap axially at least partially, wherein the first permanent magnet () is disposed offset relative to the second permanent magnet (). In the axial overlap region () of the first permanent magnet () and the second permanent magnet (), the housing () is positioned between the two permanent magnets (). A first bearing () is configured for the relative axial positioning of the rotor () and the housing () with respect to one another and for receiving an axial force resulting from the arrangement of the first permanent magnet () and the second permanent magnet (), and a second bearing () and a third bearing () are configured for receiving radial forces and for positioning the axis of rotation of the second permanent magnet ().

The invention relates to a method for producing components of a tilting-pad bearing (), wherein: the tilting-pad bearing () has an outer ring () and multiple tilting pads () preferably arranged at regular angular intervals about a longitudinal axis () of the outer ring (); the tilting pads () are pivotably mounted with an outer surface () about a pitch line () on an inner surface () of the outer ring (); and a blank () in the form a cylinder portion () having a constant wall thickness is used to produce the tilting pads () from a tilting pad ring () or to produce the outer ring (). The invention is characterised in that: a radial force (F) acting in the direction of the longitudinal axis () is applied to the cylinder portion () at multiple clamping points () in the region of its outer periphery (), said radial forces (F) elastically deforming the cylinder portion (); an inner bore () having a round cross-section is subsequently produced on the inner surface () of the elastically deformed cylinder portion (); and subsequently the radial clamping of the cylinder portion () is stopped.

A foil segment bearing comprises a bearing backing with a through opening. A shaft is arranged in the through opening such that a gap exists between the shaft and the bearing backing. The foil segment bearing also has at least one first bearing segment and one second bearing segment with respective inner surfaces. Each of the respective inner surfaces defines a bearing surface with an adjustable circumference. The bearing segments are arranged in the bearing backing at a distance from the shaft such that a gap exists between the shaft and the bearing segments. The foil segment bearing also has a foil arrangement arranged in the gap between the inner surfaces of the bearing segments and the shaft. The foil segment bearing also has an adjustment mechanism configured to set a geometry of the gap.

A foil bearing includes a bearing back, a foil arrangement, and a setting mechanism. The bearing back includes a passage opening configured to receive a shaft, such that a gap is formed between the shaft and the bearing back. The foil arrangement defines a first inner circumference and includes a first segment-shaped foil arranged in the gap adjacent to the bearing back, a second segment-shaped foil arranged in the gap adjacent to the first segment-shaped foil, and a third segment-shaped foil arranged in the gap between the shaft and the second segment-shaped foil. The setting mechanism is configured to set the first inner circumference.

The invention pertains to a plain porous bearing for motors and transmissions with a circular bearing bore that displays, distributed alternatingly across the bearing bore, highly compressed at least approximately closed-pore areas and slightly compressed, open-pore areas, where the bearing bore diameters of the highly and slightly compressed areas are at least approximately identical. Also provided is a procedure and device for production of the bearing.

A high-pressure pump having a drive shaft and at least one pump element including a pump piston driven in a reciprocating motion by the drive shaft. A ring on which the pump piston is braced via a support element is rotatably supported on a portion of the drive shaft that is disposed eccentrically to its pivot axis. The ring and/or the support element, at least in their contact region, has many microscopic indentations, and a solid lubricant film is applied to the ring and/or to the support element, at least in their contact region.

A lubricant varnish component and a lubricant varnish, for example, for coating elastomer profiles, are provided, wherein lubricant varnish component includes a polyurethane, a siloxane as well as a polyamide powder, a polyethylene powder or a solution of a polyamide. The lubricant varnish may additionally contain a curing agent, in particular an isocyanate-based curing agent. In addition, a first method for coating elastomers is proposed, wherein the proposed lubricant varnish is first applied in the form of a coating to an elastomer profile, and this coating then being dried and/or thermally crosslinked. Also, the proposed lubricant varnish, having or not having polyamide or polyethylene, may first be applied in the form of a first coat to the elastomer profile, and an alcoholic or aqueous solution of a polyamide in the form of a second coat or a polyamide powder or a polyethylene powder may then being applied to the first coat. The proposed lubricant varnish is suitable, for example, for the production of coated windshield wiper blades having a reduced coefficient of dry friction.

A sintered plain bearing for motors and gear drives, having a running surface formed by a bearing bore and capable of having lubricant applied to it from lubricant reservoirs in the bearing, in which the bearing bore has, alternatingly distributed over the circumference, high-compaction small-pore running surfaces and axially extending low-compaction open-pore lubricant reservoirs. Lubrication is improved, especially in the initial phases of operation, by the fact that the lubricant reservoirs are constituted by channel structures having at least two longitudinal channels, and that at least in some of the channel structures, some of the channel crests remaining between adjacent longitudinal channels are in contact with the shaft received by the bearing bore in order to transfer lubricant.
