Description

Technisches Gebiet der ErfindungTechnical field of the invention

Die vorliegende Erfindung betrifft das Gebiet der Textilmaschinen und insbesondere eine Falschdrallaggregatsspindel und ein Falschdrallaggregat.The present invention relates to the field of textile machines, and more particularly to a false twisting unit spindle and a false twisting unit.

Allgemeiner Stand der TechnikGeneral state of the art

Der Stand der Technik ist in den folgenden Dokumenten offenbart: GB1310124 A , DE3702530 A1 , CN102021699 A , EP2295621 A1 und WO2006/005389 A1 .The prior art is disclosed in the following documents: GB1310124 A . DE3702530 A1 . CN102021699 A . EP2295621 A1 and WO2006 / 005389 A1 ,

Die Falschdrallaggregatsspindel ist eine wesentliche Komponente eines Falschdrallaggregats und übt nicht nur eine die Friktionsscheibe stützende Funktion aus, sondern treibt die Friktionsscheibe drehend an und erfüllt so die Aufgabe der Friktionsdrehung bei Chemiefasern.
Figur 1 der beiliegenden Zeichnungen zeigt eine Schnittansicht einer Falschdrallaggregatsspindel des Stands der Technik, wobei die Falschdrallaggregatsspindel eine Kernwelle 1 und ein die Kernwelle 1 umgebendes Lager 2 umfasst. Am Endstück der Kernwelle 1 ist ein vom Lager 2 getrenntes Übertragungselement 3 angebracht und in der Anordnung des Falschdrallaggregats treibt die Kernwelle 1 über das Übertragungselement 3 eine andere Spindel an. Zwischen dem Übertragungselement 3 und dem Lager 2 ist ein Elektromotor 4 angeordnet, wobei der Elektromotor 4 vom Übertragungselement 3 entlang der axialen Richtung der Kernwelle 1 getrennt ist und der Elektromotor 4 die Antriebskraft für die Spindel bereitstellt.The false twist unit spindle is an essential component of a false twist unit and not only exercises a function supporting the friction disc, but drives the friction disk rotating and thus fulfills the task of friction rotation in man-made fibers.
FIG. 1 In the accompanying drawings, there is shown a sectional view of a prior art false twisting unit spindle wherein the false twisting unit spindle comprises a core shaft 1 and a bearing 2 surrounding the core shaft 1. At the end of the core shaft 1 is separated from the bearing 2 transmission element 3 is mounted and in the arrangement of the false twist unit drives the core shaft 1 via the transmission element 3 to another spindle. Between the transmission element 3 and the bearing 2, an electric motor 4 is arranged, wherein the electric motor 4 is separated from the transmission element 3 along the axial direction of the core shaft 1 and the electric motor 4 provides the driving force for the spindle.

Insbesondere umgibt der Rotor 5 des Elektromotors 4 die Kernwelle 1 entlang der radialen Richtung der Kernwelle 1 und ist mit der Kernwelle 1 verbunden und der Stator 6 ist mit dem Gehäuse 7 des Elektromotors 4 verbunden, wobei auf den Stator 6 eine Drahtspule gewickelt ist und der Rotor 5 und der Stator 6 entlang der radialen Richtung der Kernwelle 1 voneinander getrennt sind. Durch die Drehung des Rotors 5 und des Stators 6 gegeneinander wird eine Umwandlung von mechanischer und elektrischer Energie realisiert und somit die Kernwelle 1 in Umfangsrichtung drehend angetrieben. Das Gehäuse 7 des Elektromotors weist einen mit dem Lageraußenring 9 verbundenen Verbindungsring 8 auf, wobei der Verbindungsring 8 das Lager 2 entlang der radialen Richtung der Kernwelle 1 umgibt und mit dem Lageraußenring 9 verbunden ist.Specifically, the rotor 5 of the electric motor 4 surrounds the core shaft 1 along the radial direction of the core shaft 1 and is connected to the core shaft 1 and the stator 6 is connected to the housing 7 of the electric motor 4, wherein a wire spool is wound on the stator 6 and the Rotor 5 and the stator 6 along the radial direction of the core shaft 1 are separated from each other. By the rotation of the rotor 5 and the stator 6 against each other, a conversion of mechanical and electrical energy is realized, and thus the core shaft 1 is rotationally driven in the circumferential direction. The housing 7 of the electric motor has a connected to the bearing outer ring 9 connecting ring 8, wherein the connecting ring 8, the bearing 2 along the radial direction of the core shaft 1 surrounds and is connected to the bearing outer ring 9.

Wenn die Falschdrallaggregatsspindel in der am Falschdrallaggregatssockel angeordneten Sockelbohrung montiert wird, wird das Ende der Kernwelle 1, an dem kein Übertragungselement 3 montiert ist, zuerst in die Sockelbohrung eingeführt, und anschließend wird das Lager 2 in die Sockelbohrung eingeführt. Da aber der Außendurchmesser des Verbindungsrings 8 größer als der Außendurchmesser des Lageraußenrings 9 ist, ragt der Verbindungsring 8 über die Außenumfangsfläche des Lageraußenrings 9 heraus, das Lager 2 kann nur teilweise in die Sockelbohrung eingeführt werden und der Verbindungsring 8 behindert ein weiteres Einführen der Falschdrallaggregatsspindel in die am Falschdrallaggregatssockel angeordnete Sockelbohrung. Deshalb muss am Falschdrallaggregatssockel erneut eine Sockelbohrung konstruiert werden, um die Falschdrallaggregatsspindel in geeigneter Weise zu montieren.When the false twisting unit spindle is mounted in the socket bore disposed on the false twist assembly socket, the end of the core shaft 1 to which no transmission member 3 is mounted is first inserted into the socket bore, and then the bearing 2 is inserted into the socket bore. However, since the outer diameter of the connecting ring 8 is larger than the outer diameter of the bearing outer ring 9, the connecting ring 8 protrudes beyond the outer peripheral surface of the bearing outer ring 9, the bearing 2 can only be partially inserted into the base bore and the connecting ring 8 hinders further insertion of the false twisting unit spindle arranged on Falschdragagagtsrammel base socket. Therefore, a pedestal hole must again be constructed on the false twist assembly base to properly mount the false twist unit spindle.

Die Aufgabe, die die vorliegende Erfindung lösen soll, ist die Montage der Falschdrallaggregatsspindel entlang der axialen Richtung der Kernwelle in der Sockelbohrung des Falschdrallaggregatssockels, was durch den Verbindungsring behindert wird.The object to be solved by the present invention is to mount the false twist assembly spindle along the axial direction of the core shaft in the base hole of the false twist assembly base, which is hindered by the connection ring.

Entsprechend den Figuren 2 und 3 umfasst die Falschdrallaggregatsspindel eine Kernwelle 10, ein die Kernwelle 10 umgebendes Lager 20 und einen an einer Seite des Lagers 20 auf der Kernwelle 10 angeordneten Elektromotor 30.According to the Figures 2 and 3 The false twist unit spindle comprises a core shaft 10, a bearing 20 surrounding the core shaft 10 and an electric motor 30 arranged on one side of the bearing 20 on the core shaft 10.

Das Lager 20 umfasst einen die Kernwelle 10 umgebenden Lageraußenring 21, zwei zwischen dem Lageraußenring 21 und der Kernwelle 10 angeordnete Rollenkörpergruppen (ohne Bezugsziffern), wobei die Rollenkörper dafür sorgen, dass der Lageraußenring 21 und die Kernwelle 10 gegeneinander beweglich sind.
