Beschreibung
Zusammenfassung:The roller (1) has a main body (3) made from a plastic material i.e. polyamide, and a bearing (5) i.e. rolling bearing, inserted in the body for rotatable mounting of the body. The body includes an external periphery surface (9) that is turned toward a traction unit e.g. belt or chain, where the periphery surface is partially provided with a metallic coating (10). The coating consists of transition metal such as nickel, cobalt, iron, silver, titanium and copper and/or metal alloys. The body consists of reinforcing fibers such as carbon fibers, glass fibers and aramid fibers. Die Erfindung betrifft eine Spann- und/oder Umlenkrolle (1) für einen Zugmitteltrieb, mit einem Hauptkörper (3) aus einem Kunststoffmaterial, in dem ein Lager (5) zur drehbaren Lagerung des Hauptkörpers (3) eingesetzt ist, wobei der Hauptkörper (3) eine Außenumfangsfläche (9) aufweist, die einem auszulenkenden Zugmittel zugewandt ist, wobei die Außenumfangsfläche (9) zumindest abschnittsweise mit einer metallischen Beschichtung (10) versehen ist. Die Erfindung betrifft auch einen Zugmitteltrieb mit einem Zugmittel, wie einem Riemen, der mit derr Umlenkrolle in Kontakt steht.
