Abstract
Description
Die Erfindung betrifft eine Spindellagerung für eine Doppeldraht-Zwirnspindel nach dem Oberbegriff des Anspruchs 1.The invention relates to a spindle bearing for a double-twisting spindle according to the preamble of
Übliche Doppeldraht-Zwirnspindeln umfassen eine Spindellagerung, ein angetriebenes Rotorelement und einen Schutztopf zur Aufnahme der Spule. Ihre Spindellagerung hat zwei Lagerbereiche. In einem Oberlagerbereich wird der Schutztopf auf dem Rotorelement und relativ zu diesem drehbar gelagert. In einem Unterlagerbereich werden sowohl die Andruckkräfte eines Tangentialriemens, der mittels eines Wirtels das Rotorelement antreibt, als auch die axial wirkenden Kräfte aus dem Gewicht des Schutztopfes und der darin befindlichen Spule aufgenommen. Die Wälzlagerungen des Unterlagerbereichs sind auf eine übliche Lebensdauer von ca. 50.000 h ausgelegt. Die Wälzlagerungen im Oberlagerbereich sind dagegen so ausgelegt, dass sie diese Lebensdauer nicht erreichen. Sie werden nach einer Betriebsdauer, die zwischen 20.000 und 30.000 h liegt, gewechselt. Der Wechsel kann einfach und schnell vorgenommen werden, da der Oberlagerbereich nach Entfernen des Schutztopfes gut zugänglich ist. Beim Unterlagerbereich ist diese leichte Zugänglichkeit nicht vorhanden, da der Wirtel auf den Spindelschaft des Rotorelementes aufgepresst ist und somit ein Abziehen des Wirtels nicht möglich ist. Die Wälzlagerungen im Unterlagerbereich werden daher üblicherweise mit Standardfetten nachgeschmiert, um die Lebensdauer von 50.000 h zu erhalten.Conventional double-twisting spindles include a spindle bearing, a driven rotor element and a protective pot for receiving the spool. Your spindle bearing has two storage areas. In a top storage area, the protective pot is rotatably mounted on the rotor element and relative thereto. In a sub-storage area, both the pressure forces of a tangential belt, which drives the rotor element by means of a whorl, and the axially acting forces are absorbed by the weight of the protective pot and the coil located therein. The rolling bearings of the sub-storage area are designed for a typical service life of approx. 50,000 h. The rolling bearings in the upper bearing area, however, are designed so that they do not reach this life. They are changed after an operating time of between 20,000 and 30,000 h. The change can be made easily and quickly, since the upper bearing area is easily accessible after removing the protective pot. In the sub-storage area, this easy accessibility is not present, since the whorl is pressed onto the spindle shaft of the rotor element and thus a removal of the whorl is not possible. The rolling bearings in the sub-storage area are therefore usually relubricated with standard greases in order to preserve the service life of 50,000 hours.

Es ist Aufgabe der Erfindung, die beschriebenen Nachteile zu beseitigen und die bekannten Spindellagerungen zu verbessern. Diese Aufgabe wird mit einer Spindellagerung mit den Merkmalen des Anspruchs 1 gelöst.It is an object of the invention to eliminate the disadvantages described and to improve the known spindle bearings. This object is achieved with a spindle bearing with the features of
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Ein von oben durch den Fadenleitkörper parallel zur Rotationsachse des Spindelschaftes verlaufender und in die untere Lagereinrichtung mündender Schmiermittelkanal ist nach Abnehmen des Schutztopfes für den Befettungsvorgang leicht zugänglich. Das Aufsetzen einer Fettpresse erfolgt in vertikaler Richtung und ist ergonomisch günstig für die Wartungsperson. Das Schmiermittel kann aufgrund der vertikalen Lage der Spindel und der Laufschwingungen des Lagers, unterstützt durch die Schwerkraft, in den Lagerbereich eintreten.A running from above through the Fadenleitkörper parallel to the axis of rotation of the spindle shaft and opening into the lower bearing means lubricant channel is easily accessible after removing the protective cup for the Befettungsvorgang. The placement of a grease gun takes place in the vertical direction and is ergonomically favorable for the maintenance person. The lubricant may enter the bearing area due to the vertical position of the spindle and the running vibrations of the bearing supported by gravity.
Ist der Schmiermittelkanal in eine Befestigungsschraube mit nach oben weisendem Schraubenkopf eingebracht, mit der der Fadenleitkörper relativ zum Spindelschaft fixierbar ist, ist neben den Bohrungen für die Befestigungsschrauben kein zusätzlicher Fettkanal durch den Fadenleitkörper erforderlich. Ein üblicher Schmiernippel ist nicht erforderlich. Dadurch werden sowohl Kosten für einen üblichen Schmiernippel als auch Kosten für die Montage eines solchen Schmiernippels vermieden.If the lubricant channel is introduced into a fastening screw with an upwardly pointing screw head with which the thread guide body can be fixed relative to the spindle shaft, no additional grease channel through the thread guide body is required in addition to the holes for the fastening screws. A usual grease nipple is not required. As a result, both costs for a common grease nipple and costs for the installation of such a grease nipple are avoided.
Mit einer farblichen Kennzeichnung des Schraubenkopfes, durch die er von Schraubenköpfen weiterer Befestigungsschrauben ohne Schmiermittelkanal unterscheidbar ist, ist die Lage der Befestigungsschraube mit Schmiermittelkanal auf den ersten Blick erkennbar und ein schnelles Nachschmieren möglich.With a color coding of the screw head, by means of which it can be distinguished from screw heads of further fastening screws without lubricant channel, the position of the fastening screw with lubricant channel can be recognized at first glance and a quick relubrication is possible.
Beträgt der Durchmesser des Schmiermittelkanals maximal 1,2 mm, sind sowohl die Größe des Durchlasses für das Schmiermittel als auch die Haltewirkung der Befestigungsschraube ausreichend.If the diameter of the lubricant channel is at most 1.2 mm, both the size of the passage for the lubricant and the holding action of the fastening screw are sufficient.
Vorteilhaft durchquert der Schmiermittelkanal einen Ring, der den Spindelschaft umgibt und fest mit diesem verbunden ist. Ein solcher Ring bewirkt ein Stabilisieren der Befestigung und erlaubt ein sicheres Angreifen der Schraube.Advantageously, the lubricant passage passes through a ring which surrounds the spindle shaft and is firmly connected thereto. Such a ring stabilizes the attachment and allows a secure engagement of the screw.
Bevorzugt ist der rotierende Ring und die untere Lagereinrichtung von einem stillstehenden Lagergehäuse umgeben und zwischen dem Lagergehäuse und dem Ring eine Spaltdichtung gebildet. Die Spaltdichtung verhindert, dass das durch den Schmiermittelkanal in die untere Lagereinrichtung eingebrachte Schmiermittel wieder nach oben steigt. Dies erfolgt auf einfache Weise durch eine solche Ausbildung des Ringes, dass zwischen dem Ring und dem Lagergehäuse nur ein geringer Abstand besteht, wodurch hier keine zusätzlichen Dichtungselemente benötigt werden. Mit zusätzlichen Dichtungselementen verbundener Montageaufwand wird vermieden.Preferably, the rotating ring and the lower bearing device is surrounded by a stationary bearing housing and formed between the bearing housing and the ring a gap seal. The gap seal prevents the lubricant introduced into the lower bearing device through the lubricant channel from rising upwards again. This is done in a simple manner by such a design of the ring that only a small distance between the ring and the bearing housing, whereby no additional sealing elements are needed here. Assembly costs associated with additional sealing elements are avoided.
Vorteilhaft umfasst die untere Lagereinrichtung zwei axial zueinander beabstandete Wälzlager, wobei über dem oberen Wälzlager ein Schmiermittelspeicher angeordnet ist, in den der Schmiermittelkanal mündet. Auf diese Weise lässt sich ein ausreichender Schmiermittelvorrat in die untere Lagereinrichtung einbringen, der sich bei Rotation des Rotorelementes unter Einfluss der Schwerkraft so verteilen kann, dass beide Wälzlager zufrieden stellend geschmiert werden.Advantageously, the lower bearing means comprises two axially spaced rolling bearings, wherein above the upper roller bearing a lubricant reservoir is arranged, in which the lubricant channel opens. In this way, a sufficient supply of lubricant can be introduced into the lower bearing device, which can be distributed during rotation of the rotor element under the influence of gravity so that both bearings are lubricated satisfactorily.
Wird der Spindelschaft mittels eines topfförmigen Wirtels angetrieben, wobei der Wirtel das Lagergehäuse der unteren Lagereinrichtung mindestens teilweise umschließt, ist eine kompakte Bauweise der Spindellagerung möglich. Lage und Ausbildung des Wirtels erlauben eine weitgehend gleichmäßige Belastung der Wälzlager der unteren Lagereinrichtung.If the spindle shaft is driven by means of a cup-shaped whorl, the whorl at least partially enclosing the bearing housing of the lower bearing device, a compact construction of the spindle bearing is possible. Location and Training the whorl allow a largely uniform load on the bearings of the lower bearing device.
Die erfindungsgemäße Spindellagerung ermöglicht eine kompakte, kostengünstige Bauform und eine Verbesserung der Schmierung.The spindle bearing according to the invention enables a compact, cost-effective design and an improvement in lubrication.

Am oberen Ende des Spindelschaftes 3 ist eine obere Lagereinrichtung 16 angeordnet, auf die der Schutztopf 2 aufgesetzt ist. Dadurch ist der Schutztopf 2 relativ zum Spindelschaft 3 drehbar. Im Schutztopf 2 ist eine Spule aufsteckbar, von der in
Die Befestigungsschrauben 13, 14, 15 sind als Innensechskantschrauben ausgebildet.
Der Schmiermittel kanal 18 mündet in einen Hohlraum 23 oberhalb des Wälzlagers 9 der unteren Lagereinrichtung 7, wobei der Hohlraum 23 als Schmiermittelspeicher dient. Der Ring 5 ist derart geformt, dass er mit dem ihn umgebenden stillstehenden Lagergehäuse 8 eine Spaltdichtung 24 bildet.The
Bei der Wartung, die durchgeführt wird, um den Zustand der Wälzlager 20, 21 der oberen Lagereinrichtung 16 zu überprüfen, wird der Schutztopf 2 vom Spindelschaft 3 abgenommen. Damit ist gleichzeitig die Befestigungsschraube 13 sichtbar beziehungsweise freigelegt geworden und ohne zusätzlichen Aufwand ein leichter, unbehinderter Zugang zu den Befestigungsschrauben 13, 14, 15 geschaffen.

Üblicherweise erfolgt das Einbringen des als Schmiermittel verwendeten Fettes mit einer Fettpresse. Die Fettpresse kann, ergonomisch günstig für die Bedienungsperson, in vertikaler Lage auf den Schraubenkopf 19 der Befestigungsschraube 13 aufgesetzt werden. Die für die untere Lagereinrichtung 7 benötigte Fettmenge wird durch den Schmiermittelkanal 18 der Befestigungsschraube 13 in den Hohlraum 23 eingebracht. Die Spaltdichtung 24 verhindert, dass das Fett aus dem Hohlraum 23 nach oben steigt und damit aus der unteren Lagereinrichtung 7 austritt. Der Hohlraum 23 ist so bemessen, dass die für die ausreichende Schmierung der Wälzlager 9, 10 benötigte Fettmenge den Hohlraum 23 nicht ganz auffüllt. Das Fett beziehungsweise das im Fett befindliche Öl kann aufgrund der vertikalen Anordnung des Spindelschaftes 3 und damit der vertikalen Anordnung der unteren Lagereinrichtung 7 und unter Einfluss der Schwerkraft sowie der Laufschwingungen, denen die untere Lagereinrichtung 7 unterworfen ist, die Wälzlager 9, 10 erreichen und in diese eintreten.Usually, the introduction of the grease used as a lubricant is done with a grease gun. The grease gun can, ergonomically favorable for the operator to be placed in a vertical position on the
