Additiven unter Vermischen, ein entsprechendes Verfahren und die Verwendung der calciumligninsulfonat-haltigen Schmierfette.
Abstract:
In einer elektrischen Maschine mit einem Wälzlager (3), dessen Innenring (5) auf der Rotorwelle (2) der elektrischen Maschine sitzt, dessen Außenring (4) in einem Gehäuse (1) sitzt und das sich in einem abgeschlossenen Raum (8) befindet soll das Wälzlager (3) vor elektrischen Durchschlägen geschützt sein. Dazu enthält der Raum (8) eine Flüssigkeit auf wässriger Basis, deren Spiegel (13) die Außenkontur des Innenringes an seiner tiefsten Stelle (14) überragt. Dadurch sind Innenring (5) und Außenring (4) leitend verbunden und der Spannungsausgleich zwischen Rotor und Gehäuse (1) der elektrischen Maschine kann ungehindert und ohne Durchschläge erfolgen. In einer Anwendung als Getriebemotor ist auch das Schmiermittel des Getriebes eine Flüssigkeit auf wässriger Basis.
Abstract:
A method for reducing wear between two surfaces in sliding contact with one another includes introducing nanoparticles between the two surfaces in an amount and having a composition that results in shear lines being generated within at least one agglomerated wear particle that is generated between the two surfaces as a result of the sliding contact, and subjecting the agglomerated wear particles to at least one load, using at least one of the two surfaces, such that the agglomerated wear particles disassemble along the shear lines into multiple smaller wear particles.
