Description
Die bekannten Gleitlager im Triebwerk der Verbrennungsmotoren bestehen aus Stahlwellen oder -Bolzen, welche in einem Futter aus Bronce-oder Weißmetall-Legierung drehbar gelagert sind.The known slide bearings in the engine of internal combustion engines consist of steel shafts or bolts, which are rotatably mounted in a lining made of bronze or white metal alloy.
Nach der Erfindung sollen Wellen und Bolzen aus Hartmetall oder solchen mit einer Hartmetalloberfläche in Schalen oder Büchsen aus Hartmetall oder solchen mit einer Gleitfläche aus Hartmetall drehbar gelagert sein. Unter Hartmetall sind Werkstoffe zu verstehen, wie sie in der Zerspanung als Schneidwerkstoff Anwendung finden - etwa Sintermetalle auf WC-Co bzw. WC-TiC-Co-Basis oder auch Eisen-Wolfram-Grundmasse. Hierdurch wird eine ganz bedeutende Steigerung der Lebensdauer der Lager bei entsprechender Verringerung der Lagerfläche erreicht, da Hartmetall nicht zum Festfressen neigt, sehr hohen Reibungsbeanspruchungen gewachsen ist, große Verdrehungs-, Druck-, Scher-, Verschleiß- und Hitzebeständigkeit besitzt.According to the invention, shafts and bolts made of hard metal or those with a hard metal surface should be rotatably mounted in shells or bushes made of hard metal or those with a sliding surface made of hard metal. Tungsten carbide is understood to mean materials that are used as cutting materials in machining - such as sintered metals based on WC-Co or WC-TiC-Co or iron-tungsten base material. This results in a very significant increase in the service life of the bearings with a corresponding reduction in the bearing area, since hard metal does not tend to seize, can withstand very high frictional loads, and is resistant to torsion, pressure, shear, wear and heat.
