Abstract

In a spindle driven by a single electric motor in a spinning machine, the bearing housing receiving a shank connected fixedly in terms of rotation to a rotor carries the stator and is fastened via a damping element to a spindle rail which is gripped over some of its axial height by a pot-like recess. <IMAGE>

Description

Die Erfindung betrifft eine Spindel mit elektromotorischem Ein­zelantrieb für eine Spinnmaschine, die einen in einem Lagerge­häuse gelagerten Schaft aufweist, der drehfest mit einem Rotor verbunden ist, dessen zugehöriger Stator drehfest mit dem in der Spindelbank gehaltenen Lagergehäuse verbunden ist.The invention relates to a spindle with a single electric motor drive for a spinning machine, which has a shaft mounted in a bearing housing, which is connected in a rotationally fixed manner to a rotor, the associated stator of which is connected in a rotationally fixed manner to the bearing housing held in the spindle bank.

Derartige Spindeln werden insbesondere bei Ringspinnmaschinen oder Ringzwirnmaschinen eingesetzt und sollten vorzugsweise mit hohen Drehzahlen laufen.Such spindles are used in particular in ring spinning machines or ring twisting machines and should preferably run at high speeds.

Der Erfindung liegt die Aufgabe zugrunde, eine Spindel der ein­gangs genannten Art so auszubilden, daß einerseits eine ge­dämpfte Anbringung an einer Spindelbank möglich ist, während andererseits ein kleiner und weitgehend konstanter Luftspalt zwischen Stator und Rotor vorgesehen werden kann.The invention has for its object to provide a spindle of the type mentioned so that on the one hand a damped attachment to a spindle bank is possible, while on the other hand a small and largely constant air gap can be provided between the stator and rotor.

Diese Aufgabe wird dadurch gelöst, daß der Stator auf einer Platte angebracht ist, die an dem Lagergehäuse befestigt ist und die über ein gummielastisches Dämpfungselement mit einer das Lagergehäuse mit Abstand umgebenden, an der Spindelbank be­festigbaren Hülse abgestützt ist, wobei das ringförmige Dämp­fungselement mit einer topfartigen Aussparung der Platte und/­oder der Hülse über einen Teil der axialen Höhe eingefaßt ist.-This object is achieved in that the stator is mounted on a plate which is fastened to the bearing housing and which is supported by a rubber-elastic damping element with a sleeve which surrounds the bearing housing at a distance and can be fastened to the spindle bank, the annular damping element having a cup-like shape Recess of the plate and / or the sleeve is bordered over part of the axial height.

Bei dieser Ausbildung werden alle Bewegungen (mit Ausnahme na­türlich der Rotationsbewegung) des Spindelschaftes mit auf den Stator übertragen, der damit in das Schwingungssystem inte­griert ist. Die Statormasse dient damit als rückstellendes Ele­ment. Da das gummielastische Element normalerweise unterschied­liche Federsteifigkeiten bei Druck-Zugbelastungen und bei Scherbelastungen oder Kippbelastungen aufweist, ist es durch die topfartige Aussparung teilweise eingefaßt, so daß ein Aus­gleich und eine Vergleichmäßigung der Federsteifigkeiten in axialer und radialer Richtung erhalten werden kann. Die Abmes­sung der topfartigen Aussparung läßt sich durch Versuche ermit­teln.With this training, all movements (with the exception of course the rotational movement) of the spindle shaft are also on the Transfer stator, which is thus integrated into the vibration system. The stator mass thus serves as a restoring element. Since the rubber-elastic element normally has different spring stiffnesses under compressive tensile loads and under shear loads or tipping loads, it is partially surrounded by the pot-like recess, so that a compensation and an equalization of the spring stiffnesses in the axial and radial directions can be obtained. The dimensions of the pot-like recess can be determined by experiments.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung des in der Zeichnung dargestell­ten Ausführungsbeispiels.

  • Fig. 1 zeigt einen in zwei Ebenen verlaufenden axialen Schnitt durch eine erfindungsgemäße Spindel,
  • Fig. 2 einen Teilschnitt in vergrößertem Maß durch einen Teil der Spindel und
  • Fig. 3 ein Koordinatensystem zum Veranschaulichen der Bewegungsmöglichkeiten.
Further features and advantages of the invention result from the following description of the exemplary embodiment shown in the drawing.
  • 1 shows an axial section in two planes through a spindle according to the invention,
  • Fig. 2 is a partial section on an enlarged scale through part of the spindle and
  • 3 shows a coordinate system to illustrate the possible movements.

Der Stator (15) der Spindel besitzt ein Blechpaket aus Blechen mit im wesentlichen quadratischer Grundfläche. In den etwas ausgesparten und profilierten Ecken sind Säulen (17) angeord­net, die das Blechpaket halten. Die linke Hälfte der Fig. 1 ist in einer Ebene lotrecht zu einer Seitenkante geschnitten. Die rechte Hälfte der Fig. 1 ist in einer Diagonalebene bezüglich der quadratischen Grundfläche geschnitten.The stator (15) of the spindle has a laminated core made of laminations with an essentially square base. In the somewhat recessed and profiled corners, columns (17) are arranged which hold the laminated core. The left half of FIG. 1 is cut perpendicular to a side edge in one plane. The right half of Fig. 1 is cut in a diagonal plane with respect to the square base.

Die Spindel (10) weist ein Lagergehäuse (12) auf, in welchem ein Schaft (13) gelagert ist. Der Schaft (13) besteht aus einem in das Lagergehäuse (12) eingesteckten und dort mit einem nicht dargestellten Halslager und einem in Fig. 2 angedeuteten Fußla­ ger (29) gelagert ist. An diesem Teil (23) ist ein Teil (24) befestigt, der glockenförmig das obere Ende des Lagergehäuses (12) umgreift und der dort mit einem Rotor (14) versehen ist. Der Rotor (14) ist in üblicher Weise aufgebaut, d.h. er besitzt ein Blechpaket, in Nuten verlaufende Stäbe und Kurzschlußringe.The spindle (10) has a bearing housing (12) in which a shaft (13) is mounted. The shaft (13) consists of a plugged into the bearing housing (12) and there with a neck bearing (not shown) and a footplate indicated in FIG. 2 ger (29) is stored. A part (24) is fastened to this part (23), which surrounds the upper end of the bearing housing (12) in a bell shape and which is provided there with a rotor (14). The rotor (14) is constructed in the usual way, ie it has a laminated core, rods running in grooves and short-circuit rings.

Dem Rotor (14) ist der bereits erwähnte Stator (15) zugeordnet, der aus dem bereits erwähnten, eine annähernd quadratische Grundfläche aufweisenden Blechpaket (16) und einer Wicklung (30) gebildet ist. Das Blechpaket (16) ist an den vier Ecken mittels der angegossenen Säulen (17) zusammengehalten. Die Säu­len (17) sind an einer Platte (18) befestigt, die mit einem Kragen drehfest mit dem Lagergehäuse verbunden ist. Die Säulen (17) sind mit einer Zentrierprofilierung (31) versehen, der ei­ne entsprechende Gegenprofilierung der Platte (18) zugeordnet ist. Die Säulen (17) sind mittels Schrauben (25) an der Platte (18) befestigt, die die Platte (18) durchdringen und in die Stirnenden der Säulen (17) eingeschraubt sind.The rotor (14) is associated with the stator (15) already mentioned, which is formed from the already mentioned, approximately square base plate stack (16) and a winding (30). The laminated core (16) is held together at the four corners by means of the cast columns (17). The columns (17) are fastened to a plate (18) which is connected to the bearing housing in a rotationally fixed manner with a collar. The columns (17) are provided with a centering profile (31), to which a corresponding counter-profile of the plate (18) is assigned. The columns (17) are fastened to the plate (18) by means of screws (25) which penetrate the plate (18) and are screwed into the front ends of the columns (17).

Zwischen der Platte (18) und dem Blechpaket (16) ist eine Hülse (26) angeordnet. An dem oberen Ende der Säulen (17) ist mittels Nieten (28) eine den in diesem Bereich befindlichen Teil der Wicklung (30) überdeckende Schutzkappe (27) befestigt.A sleeve (26) is arranged between the plate (18) and the laminated core (16). A protective cap (27) covering the part of the winding (30) located in this area is fastened to the upper end of the columns (17) by means of rivets (28).

Die Platte (18) ist über ein gummielastisches, ringförmiges Dämpfungselement (19) mit einem Flansch einer Hülse (20) ver­bunden, die die Spindelbank (11) durchdringt und die an der Spindelbank (11) mittels einer aufgeschraubten Mutter (22) be­festigt ist. Die Hülse (20) umgibt das Lagergehäuse (12) mit Abstand.The plate (18) is connected via a rubber-elastic, ring-shaped damping element (19) to a flange of a sleeve (20) which penetrates the spindle bench (11) and which is fastened to the spindle bench (11) by means of a screwed-on nut (22). The sleeve (20) surrounds the bearing housing (12) at a distance.

Wie aus Fig. 2 deutlicher zu sehen ist, ist die Platte (18) mit einer ebenfalls ringförmigen, topfförmigen Aussparung versehen, durch welche das gummielastische Dämpfungselement (19) sowohl an seinem inneren Durchmesser als auch an seinem äußeren Durch­messer über einen Teil seiner axialen Höhe eingefaßt ist.As can be seen more clearly from FIG. 2, the plate (18) is also provided with an annular, cup-shaped recess, through which the rubber-elastic damping element (19) is both is bordered on its inner diameter as well as on its outer diameter over part of its axial height.

Die Bewegungen des Schaftes (13) werden auf das Lagergehäuse (12) und den Stator (15) übertragen. Dadurch ist es möglich, den Luftspalt zwischen dem Rotor (14) und dem Stator (15) recht klein und weitgehend konstant zu halten, so daß sich ein hoher Wirkungsgrad ergibt. Die übertragenen Bewegungen (Δz, Δx, Δy) sowie auch die Kippbewegungen (α und ß) sind in dem Koordina­tenkreuz der Fig. 3 dargestellt. Durch die topfartige Ausspa­rung (21), die das Dämpfungselement (19) über einen Teil seiner axialen Höhe einfaßt, ist es möglich, die bei Scherbewegungen, Kippbewegungen und Zug-Druckbewegungen auftretenden Federstei­figkeiten wenigstens annähernd auf gleiche Werte zu bringen.The movements of the shaft (13) are transmitted to the bearing housing (12) and the stator (15). This makes it possible to keep the air gap between the rotor (14) and the stator (15) quite small and largely constant, so that there is a high degree of efficiency. The transmitted movements (Δz, Δx, Δy) and also the tilting movements (α and β) are shown in the coordinate system in FIG. 3. The pot-like recess (21), which surrounds the damping element (19) over part of its axial height, makes it possible to bring the spring stiffnesses occurring in the case of shear movements, tilting movements and tension-compression movements at least approximately to the same values.
