Description
Vorrichtung zur Erhöhung der Haftreibung zwischen Seil und Treibscheibe von Fördermaschinen Die Erfindung betrifft die Erhöhung der Haftreibung zwischen Seil und Treibscheibe von Fördermaschinen, Förderhaspeln, Aufzügen oder sonstigen auf Seilzug beruhenden Antrieben durch eine Ausfüllung der Seilrille mit einer Seilschmierung oder einem sonstigen Stoff von magnetischer Permeabilität.Device to increase the static friction between rope and traction sheave of hoisting machines The invention relates to increasing the static friction between Rope and traction sheave of hoisting machines, conveyor reels, elevators and others Drives based on rope pull by filling the rope groove with rope lubrication or any other material with magnetic permeability.
Die bisher durch mechanische Reibung erzeugte Übertragung des Drehmoments von der Treibscheibe auf das Förderseil erfährt durch die magnetische Haftung eine wirksame Ergänzung. Diese ist in weiten Grenzen regelbar, nämlich mit der magnetischen Permeabilität der Ausfüllung und dem Füllungsquerschnitt der Nut sowie mit der Stärke, Richtung und Anordnung der Magnetfelder, welche quer oder längs des Seiles, mit Unterbrechungen längs der Seilumschlingung und durch natürliche oder elektrisch erregte Magnete erzeugt werden können.The transmission of torque previously generated by mechanical friction from the traction sheave to the hoisting rope is subject to magnetic adhesion effective supplement. This can be regulated within wide limits, namely with the magnetic Permeability of the filling and the filling cross-section of the groove as well as the thickness, Direction and arrangement of the magnetic fields, which cross or along the rope, with Interruptions along the rope loop and by natural or electrical excited magnets can be generated.
Die Wirkung der Nutausfüllung, welche von der einfachen Adhäsion bis zur magnetischen Sättigung sich abstufen läßt, vermindert zunächst die mechanische Reibung und unterstützt die magnetische Haftung, besonders bei Litzenseilen, die inniger umfaßt werden. Bei großer Steigerung der Permeabilität tritt eine magnetische Verhärtung der Nutausfüllung ein, welche wieder eine Erhöhung auch der mechanischen Reibung zur Folge hat. Aus diesen Faktoren wird diejenige Seilhaftung hergestellt, welche den betriebsbedingten Seilschlupf zuläßt, den Seilrutsch dagegen ausschließt.The effect of the groove filling, which ranges from simple adhesion to can be graded to the magnetic saturation, initially reduces the mechanical Friction and supports the magnetic adhesion, especially with stranded ropes that be embraced more intimately. With a large increase in permeability, a magnetic one occurs Hardening of the groove filling, which in turn increases the mechanical Causes friction. The rope adhesion is established from these factors, which allows the operational rope slip, but excludes the rope slide.
