Um die Eignung für hohe Drehzahlen zu verbessern, können zur Lagerung einer Friktionsspindel zwei Lager mit unterschiedlichen Eigenschaften, nämlich ein Festlager und ein gedämpftes Loslager vorgesehen sein. Dennoch kann insbesondere bei höheren Drehzahlen das Auftreten von Resonanzen problematisch sein.Around the suitability for can improve high speeds for storage of a friction spindle two bearings with different Properties, namely a fixed camp and a muted one Floating bearing be provided. Nevertheless, especially at higher speeds the occurrence of resonances be problematic.
Aufgabe der ErfindungTask of invention
Der Erfindung liegt die Aufgabe zugrunde, ein Friktionsfalschdrallaggregat zum Texturieren von Garnen anzugeben, welches sich durch ein besonders breites nutzbares Drehzahlband auszeichnet.Of the Invention is the object of a Friktionsfalschdrallaggregat for texturing yarns, which is characterized by a particular broad usable speed range distinguishes.
Zusammenfassung der ErfindungSummary the invention
Diese Aufgabe wird erfindungsgemäß gelöst durch ein Friktionsfalschdrallaggregat mit den Merkmalen des Anspruchs 1. Dieses zum Texturieren von Garnen vorgesehene Aggregat weist eine Anzahl, typischerweise drei, Friktionsspindeln auf, welche jeweils mittels eines ersten, als Festlager fungierenden Lagers und eines zweiten, axial von diesem beabstandeten Loslagers, gelagert sind. Erfindungsgemäß ist das erste Lager als Wälzlager, insbesondere Rillenkugellager, und das zweite, zumindest in geringem Maße dämpfende Eigenschaften aufweisende Lager als Magnetlager ausgebildet. Hierbei ist das Magnetlager dem vom Lagerbereich auskragenden freien Ende der Friktionsspindel zugewandt. Der besondere Vorteil des Magnetlagers besteht darin, dass es die radiale Position des rotierenden Teiles, hier der Welle der Friktionsspindel, nicht vollkommen festlegt und gleichzeitig eine besondere Eignung für hohe Drehzahlen von beispielsweise mehreren 10.000 Umdrehungen/min aufweist.These The object is achieved by a Friktionsfalschdragaggregat with the features of the claim 1. This provided for texturing yarns aggregate points a number, typically three, friction spindles which each by means of a first, acting as a fixed bearing camp and a second, axially spaced from this movable bearing stored are. This is according to the invention first bearings as rolling bearings, in particular deep groove ball bearings, and the second, at least in small Dimensions damping Characteristics bearing designed as a magnetic bearing. in this connection the magnetic bearing is the free end projecting from the bearing area facing the friction spindle. The special advantage of the magnetic bearing is that it is the radial position of the rotating part, here the shaft of the friction spindle, not perfectly fixed and at the same time a special suitability for high speeds of example several 10,000 revolutions / min.
Nach einer besonders einfachen Ausführungsform ist das Magnetlager als Permanentmagnetlager ausgebildet. Dieses kann entweder attraktiv oder repulsiv wirken. Ebenso können als Magnetlager jedoch auch aktive, d.h. mit Elektromag neten arbeitende Magnetlager zum Einsatz kommen. Auch eine Kombination aktiver und passiver Magnetlagerung ist realisierbar, indem beispielsweise bei einem ansonsten passiven Magnetlager lediglich die Dämpfung aktiv geregelt wird.To a particularly simple embodiment the magnetic bearing is designed as a permanent magnet bearing. This can either be attractive or repulsive. Likewise, as However, magnetic bearings are also active, i. working with electric motors Magnetic bearings are used. Also a combination of active and passive magnetic bearing is feasible, for example, at an otherwise passive magnetic bearing only the damping active is regulated.
Als besonders vorteilhaft hat es sich erwiesen, wenn das Magnetlager relativ zur Rotationsachse der Friktionsspindel schräggestellte, den Luftspalt des Lagers begrenzende Polflächen aufweist. Durch die Schrägstellung der Polflächen, welche vorzugsweise 30° bis 60° beträgt, weist das Magnetlager sowohl axiale als auch radiale Führungseigenschaften auf. Durch die Größe des Luftspaltes zwischen den Polflächen sind auf einfache Weise die Dämpfungs- und Vorspanneigenschaften des als Loslager der Friktionsspindel fungierenden Magnetlagers einstellbar. Die schräggestellten Polflächen des Magnetlagers beschreiben einen Konus, dessen Spitze dem Festlager der Friktionsspindel zugewandt oder abgewandt sein kann.When It has proven particularly advantageous if the magnetic bearing tilted relative to the axis of rotation of the friction spindle, Having the air gap of the bearing limiting pole faces. Due to the inclination the pole faces, which preferably 30 ° to 60 °, points the magnetic bearing on both axial and radial guide properties. By the size of the air gap between the pole faces are easily the damping and Preload properties of acting as a floating bearing of the friction spindle Magnetic bearing adjustable. The inclined pole faces of the Magnetic bearings describe a cone whose tip is the fixed bearing may face the friction spindle or facing away.
Nach einer vorteilhaften Weiterbildung weist die Friktionsspindel einen integrierten elektromotorischen Antrieb auf, wobei Rotor und Stator des Elektromotors vorzugsweise axial zwischen dem Wälzlager und dem Magnetlager angeordnet sind. Der Elektromotor ist vorzugsweise als Permanentmagnetmotor aufgebaut, ebenso ist jedoch beispielsweise auch ein fremderregter Elektromotor verwendbar. Zur Lagerung von Rotorwicklungen bzw. Permanentmagneten eignen sich Hülsen, die drehfest mit den Friktionsspindeln verbunden sind und bevorzugt als Tiefziehteile gefertigt sind.To an advantageous development, the friction spindle has a integrated electromotive drive on, with rotor and stator the electric motor preferably axially between the rolling bearing and the magnetic bearing are arranged. The electric motor is preferably constructed as a permanent magnet motor, however, for example Also a foreign excited electric motor usable. For storage of Rotor windings or permanent magnets are sleeves, the rotatably connected to the friction spindles and preferred are manufactured as deep-drawn parts.
Unabhängig davon, ob die Friktionsspindel direkt elektromotorisch oder indirekt, beispielsweise über einen Riemen, angetrieben ist, ist das die Lager umhüllende, ggf. auch den Elektromotor aufnehmende Gehäuse besonders rationell als Tiefziehteil herstellbar. Entsprechendes gilt für Gehäuseabdeckungen sowie für Anschlussteile, die eine drehbare Lagerung der Friktionsspindel ermöglichen. Letztgenannte Anschlussteile können auch einteilig mit dem im Wesentlichen zylindrischen Gehäusemantel oder mit einer Gehäuseabdeckung ausgebildet sein.Independently of, whether the friction spindle directly by electric motor or indirectly, for example via a Belt is driven, this is the bearing enveloping, possibly also the electric motor receiving housing especially rational as deep-drawn part manufacturable. The same applies to housing covers also for Connecting parts, the rotatable mounting of the friction spindle enable. The latter connection parts can also in one piece with the substantially cylindrical housing shell or with a housing cover be educated.
Die Magnetlagerringe, aus welchen das Magnetlager aufgebaut ist, sind in fertigungstechnisch besonders günstiger Weise bevorzugt mit der Welle der Friktionsspindel bzw. mit einem nicht rotierenden Gehäuseteil verklebt. Zusätzlich zum Magnetlager kann eine mechanisch wirkende Dämpfungsvorrichtung vorgesehen sein. Im Gegensatz zum Magnetlager legt das Wälzlager die axiale und radiale Position der Welle der Friktionsspindel genau fest. Das Wälzlager kann in einfachen Ausgestaltungen Wälzkörper, insbesondere Kugeln, aus Stahl aufweisen. Von besonderem Vorteil, insbesondere aufgrund der geringeren Massen, ist jedoch der Einsatz eines Hybridlagers mit Wälzkörpern aus Keramik. Der Außenring des Wälzlagers ist hierbei aus Stahl gefertigt. In einer aufwändigeren Bauform sind auch Vollkeramiklager als Festlager verwendbar.The Magnetic bearing rings, from which the magnetic bearing is constructed, are in manufacturing technology particularly favorable way preferably with the shaft of the friction spindle or with a non-rotating housing part bonded. additionally to the magnetic bearing can be provided a mechanically acting damping device be. In contrast to the magnetic bearing, the rolling bearing defines the axial and radial Precisely fix the position of the shaft of the friction spindle. The rolling bearing can in simple embodiments rolling elements, in particular balls, made of steel. Of particular advantage, in particular due the lesser masses, however, is the use of a hybrid bearing with rolling elements Ceramics. The outer ring of the roller bearing is made of steel. In a more elaborate design are also Full ceramic bearing usable as a fixed bearing.
