Mit der Angabe u = 1 Gramm ist direkt klar, dass an einer Stelle des Rotors 1 Gramm zuviel oder zuwenig ist. Leider hat diese direkte Angabe der Unwuchtmasse einen Nachteil: Sie f\u00fchrt leicht zu Missverst\u00e4ndnissen. Denn die Wirkung dieser Masse h\u00e4ngt vom Radius ab, auf dem sie sitzt. Je weiter au\u00dfen am Rotor, desto gr\u00f6\u00dfer die Fliehkraft und damit die Wirkung. Also sollte man dem Kollegen statt &#8220;mach mal 1 Gramm weg&#8221; besser sagen &#8220;mach mal 1 Gramm auf dem Radius 100 mm weg&#8221;.<\/p>\n<p>Und genau daf\u00fcr gibt es die Angabe der Unwucht U=u*r. Sagen Sie nun dem Kollegen &#8220;mach mal 100 g*mm weg&#8221;, dann bohrt er eben 1 Gramm auf 100 mm Radius oder 2 Gramm auf 50 mm Radius weg.<\/p>\n<p>Empfehlung: Wenn beim Radius Interpretationsspielraum ist, dann unbedingt in Unwucht [gmm] kommunizieren.
