Abstract:
The subject of the invention is a method for increasing the strength properties of bearing sleeves and a unit for increasing the strength properties of bearing sleeves, to be used in manufacturing and regeneration of slide bearings with special working conditions, such as plane engines or rocket engines. Characterised by placing on the internal layer of the sleeve (T) a nanocomposite, graphene-like grease is placed, advantageously based on molybdenum disulfide, dissolved in anti-corrosion fluid, advantageously FC 111, in an amount of 2% to 10%, advantageously 5%, under the pressure within the range of 20 to 40 Mpa, advantageously 30 Mpa. This method is implemented in a unit characterized in that a cylindrical body, placed on a foundation (1) a sliding piston (2) is placed, having a central channel (3), connecting an impregnating chamber (4) with an impregnating socket (5), constructed in the pressing punch (6), in which a bearing sleeve (7) is placed, which has a hermetic connection of frontal surfaces with the operating surfaces of the punch (6) and upper surface of the piston (2), whereas in the external zone of the sleeve (T) the socket (5) has draining channels (8).

Abstract:
Einen Beschlag, beispielsweise eine Auszugsführung insbesondere für Haushaltsgeräte, mit mindestens zwei relativ zueinander bewegbaren Schienen, die über Wälzkörper aneinander geführt sind. Dabei sind die Laufbahnen (6, 8) der Wälzkörper (4) an den Schienen (2, 3) zumindest bereichsweise über ein Bornitrid und/oder Polysiloxan enthaltendes Schmiermittel (7) geschmiert. Dies ermöglicht einen effizienten Einsatz von Schmiermittel (7), das auch bei hohen Temperaturen beständig ist. Schmiermittel, insbesondere für Beschläge in Haushaltsgeräten, das eine Temperaturbeständigkeit von über 600°C besitzt und im Nass- und Feuchtbereich einsetzbar ist.
Abstract:
An anti-seize composition includes lubricating solids and at least one of a material selected from a grease and an oil. The lubricating solids include at least 15 weight percent of nano-sized lubricating solid particles. The nano-sized lubricating solid particles each have at least one dimension, on average, of less than 500 nm.
Abstract:
A composition that includes solid lubricant nanoparticles and an organic medium is disclosed. Also disclosed are nanoparticles that include layered materials. A method of producing a nanoparticle by milling layered materials is provided.
