Description
Die Erfindung betrifft eine Treibscheiben-Schachtfördermaschine mit einem elektrischen Motor, dessen Rotor mit einem Zylindermantel der Treibscheibe verbunden ist und dessen Stator an einer in Lagerböcken gelagerten Achse angeordnet ist, wobei der Motor innerhalb des Zylindermantels und zwischen den seitlichen Schilden der Treibscheibe in einem Hohlraum angeordnet ist, der zur Kühlung des Motors mit Kühlluft über axiale Kühlluftdurchtrittsöffnungen beaufschlagbar ist.The invention relates to a traction sheave shaft conveyor with an electric motor, the rotor is connected to a cylinder jacket of the traction sheave and the stator is arranged on a mounted in bearing blocks axis, wherein the motor disposed within the cylinder jacket and between the side shields of the traction sheave in a cavity is, which can be acted upon by cooling air via axial cooling air passage openings for cooling the engine.
Aus der
Nachteilig bei der bekannten Treibscheiben-Schachtfördermaschine ist die aufwendige Befestigung des Stators an den beiden angeschmiedeten Flanschen über lösbare Klemmringverbindungen.A disadvantage of the known traction sheave shaft carrier is the complex attachment of the stator to the two forged flanges via detachable clamping ring connections.
Außerdem benötigt die Befestigung des Stators an den beiden Klemmringen relativ viel Raum innerhalb der durch den Zylindermantel und die seitlichen Schilde begrenzten Treibscheibe. Der hohe Raumbedarf der Statorbefestigung kann Wartungs- und Prüfungsarbeiten beeinträchtigen.In addition, the attachment of the stator to the two clamping rings requires a relatively large amount of space within the limited by the cylinder jacket and the side shields traction sheave. The high space requirement of the stator mounting can impair maintenance and testing work.
Die Fertigung des Stators muss auf die Herstellung der einteiligen Achse abgestimmt werden, um die Toleranzen der beiden Flansche, der Klemmringe sowie an den Anschlüssen für den Stator zu berücksichtigen.The manufacture of the stator must be tailored to the manufacture of the one-piece axle to account for the tolerances of the two flanges, the ferrules and the stator connections.
Ein weiterer Nachteil der bekannten Treibscheiben-Schachtfördermaschine besteht darin, dass die einteilige Achse an ihren beiden Enden als Vierkant ausgebildet ist. Diese Vierkante greifen in entsprechende Aufnahmen in den Lagerböcken. An die Vierkante werden Klemmstücke mit Klemmschrauben angepresst, die wiederum in die Lagerböcke eingreifen. Diese Achsbefestigung in den Lagerböcken ist aufwendig. Des Weiteren kommt es bei Lastwechseln zu Bewegungen der Vierkante in den Aufnahmen der Lagerböcke sowie gelegentlich zu Geräuschentwicklungen.Another disadvantage of the known traction sheave shaft carrier is that the one-piece axis is formed at both ends as a square. This quadrilateral engage in corresponding receptacles in the bearing blocks. At the four-edge clamping pieces are pressed with clamping screws, which in turn engage in the bearing blocks. This axle mounting in the bearing blocks is expensive. Furthermore, it comes in load changes to movements of the square edge in the images of the bearing blocks and occasionally to noise.
Ausgehend von diesem Stand der Technik liegt der Erfindung daher die Aufgabe zu Grunde, eine Treibscheiben-Schachtfördermaschine der eingangs erwähnten Art zu schaffen, die unter Beibehaltung der Vorteile einer aus Vollmaterial bestehenden Achse eine weniger aufwendige Konstruktion erfordert, bei der sich der Stator einfacherer und günstiger ausführen und an der Achse befestigen lässt und Bewegungen der Achse in den Lagerböcken und damit eine Geräuschentwicklung nicht auftreten.Based on this prior art, the invention is therefore based on the object to provide a traction sheave shaft carrier of the type mentioned above, while maintaining the advantages of a solid material axis requires a less expensive construction, in which the stator easier and cheaper perform and fix it to the axle and movements of the axle in the bearing blocks and thus a noise does not occur.
Diese Aufgabe wird bei einer Treibscheiben-Schachtfördermaschine der eingangs erwähnten Art dadurch gelöst, dass die Achse aus zwei Teilachsen gebildet ist, die jeweils aus Vollmaterial bestehen, an jeder Teilachse stirnseitig ein äußerer Flansch und ein innerer Flansch ansetzt, zwischen den beiden inneren Flanschen ein Haltelement eingeklemmt ist, an dem der Stator befestigt ist, und die beiden äußeren Flansche an den Lagerböcken befestigt sind.This object is achieved in a traction sheave shaft conveyor of the type mentioned above in that the axis is formed of two sub-axes, each consisting of solid material, on each sub-axis an outer flange and an inner flange attaches to the end face, between the two inner flanges a holding element is clamped, on which the stator is fixed, and the two outer flanges are fixed to the bearing blocks.
Die Achse besteht aus zwei, vorzugsweise übereinstimmend aufgebauten Teilachsen aus Vollmaterial. Durch die Ausführung der Teilachsen vorzugsweise als Schmiedeteile werden die herstellungsbedingten Risiken von Gießteilen vermieden. Der Stator wird über das zwischen den beiden inneren Flanschen eingeklemmte Halteelement, insbesondere in Form eines Stegbleches, fixiert. Die nach dem Stand der Technik bisher erforderliche Verbindung des Stators über zwei Klemmringe und die damit verbundenen Nachteile entfallen vollständig. Die beiden inneren Flansche, die die Teilachsen mit Schrauben und Muttern zusammenfügen, klemmen auch das Halteelement für den Stator ein, so dass die Montage erheblich vereinfacht ist.The axis consists of two, preferably matching constructed sub-axes of solid material. By carrying out the partial axes, preferably as forgings, the production-related risks of castings are avoided. The stator is fixed on the clamped between the two inner flanges retaining element, in particular in the form of a web plate. The previously required according to the prior art connection of the stator via two clamping rings and the associated disadvantages completely eliminated. The two inner flanges, which join the sub-axes with screws and nuts, also clamp the holding element for the stator, so that the assembly is considerably simplified.
Ein weiterer Vorteil der Erfindung besteht darin, dass das Halteelement für den Stator und die Teilachsen unabhängig voneinander ausgelegt und hergestellt werden können. Die Herstellung erfordert nicht die Berücksichtigung von Fertigungstoleranzen von an der Achse im Abstand zueinander angeordneten Flanschen und Klemmringen; es sind lediglich noch die Toleranzen der Lochkreise in den inneren Flanschen und der damit fluchtenden Bohrungen in dem insbesondere als Stegblech ausgeführte Halteelement zu berücksichtigen.Another advantage of the invention is that the holding element for the stator and the sub-axes can be designed and manufactured independently of each other. The production does not require the consideration of manufacturing tolerances of the axis spaced apart flanges and clamping rings; There are only the tolerances of the bolt holes in the inner flanges and the aligned holes in the particular designed as a web plate holding element to consider.
Die Stahlkonstruktion des vorzugsweise einteilig mit dem Halteelement ausgeführten Stators kann aufgrund der einteiligen Ausführung vor Einbau komplett bearbeitet werden, da eine Berücksichtigung der Toleranzen mehrerer an den Blechpaketen des Stators angreifender Halteelemente nicht erforderlich ist. Befinden sich die Blechpakete des Stators indes zwischen zwei im Abstand zueinander angeordneten Halterungen, die mit der Achse verbunden werden, verändert sich beim Verschrauben der Blechpakete der Abstand der Halterungen zueinander, was zu Anschlussproblemen der Halterungen an der Achse führt.The steel construction of the preferably integrally formed with the holding member stator can be completely processed due to the one-piece design before installation, since a consideration of the tolerances of several acting on the laminated cores of the stator holding elements is not required. Meanwhile, the laminations of the stator are located between two spaced-apart Brackets that are connected to the axis, the distance between the brackets to each other changed when screwing the laminated cores, which leads to connection problems of the brackets on the axle.
Zum Luftspaltausgleich ist es in einer Ausgestaltung der Erfindung vorgesehen, dass der Stator an dem Halteelement radial justiert werden kann.For air gap compensation, it is provided in one embodiment of the invention that the stator can be radially adjusted to the support member.
Die beiden Teilachsen sind jeweils mit ihren äußeren Flanschen an den Lagerböcken befestigt. Durch diese Verbindung entfällt bei der Herstellung der Teilachsen die Notwendigkeit, endseitig einen Vierkant zu fräsen. Des Weiteren tragen die Schrauben an den beiden äußeren Flanschen zu einer gleichmäßigeren Lastabtragung in die Stützböcke bei. Relativbewegungen zwischen den Teilachsen und den Stützböcken werden vermieden. In Folge dessen treten auch keine störenden Betriebsgeräusche und technisch nachteilige Bewegungen auf. Insbesondere bei einem Motorkurzschlussmoment werden die auftretenden Lasten durch Scherbeanspruchung sämtlicher Schrauben der Flansche abgetragen. Ein weiterer konstruktiver Vorteil der Flanschverbindungen zwischen den Teilachsen und den Stützböcken besteht in deren guter Berechenbarkeit und Überprüfbarkeit zu Wartungszwecken.The two sub-axes are each secured with their outer flanges on the bearing blocks. Through this connection eliminates the need to mill a square at the end of the production of the sub-axes. Furthermore, the screws on the two outer flanges contribute to a more even load transfer in the support blocks. Relative movements between the sub-axes and the support blocks are avoided. As a result, no disturbing operating noise and technically disadvantageous movements occur. In particular, in the case of a motor short-circuit torque, the loads occurring are removed by shearing stress of all screws of the flanges. Another constructive advantage of the flange connections between the sub-axles and the support blocks is their good predictability and verifiability for maintenance purposes.
Das Zurückgreifen auf bewährte Flanschbindungen an beiden Seiten jeder Teilachse hat eine deutliche Vereinfachung der Konstruktion, eine gleichzeitig verbesserte Lastabtragung sowie eine optimierte Anbindung an den Stator zur Folge.The use of proven flange connections on both sides of each part axis results in a significant simplification of the construction, a simultaneously improved load transfer and an optimized connection to the stator.
Um auf einfache und wirtschaftliche Art Kühlluft zum in die Treibscheibe integrierten Motor zu bringen, umgibt jede Teilachse ein Lagersockel, wobei mindestens eine axiale Kühlluftdurchtrittsöffnung in jedem der beiden Lagersockel angeordnet ist. Die Kühlluft wird an einem der beiden Lagersockel zugeführt, durchströmt den Luftspalt zwischen Rotor und Stator und entweicht aus dem Hohlraum über Kühlluftdurchtrittsöffnungen in dem anderen der beiden Lagersockel.In order to bring cooling air to the motor integrated in the traction sheave in a simple and economic manner, each sub-axis surrounds a bearing base, wherein at least one axial cooling air-through opening is arranged in each of the two bearing sockets. The cooling air is supplied to one of the two bearing pedestals, flows through the air gap between Rotor and stator and escapes from the cavity via cooling air passage openings in the other of the two bearing base.
Auf jedem Lagersockel ist jeweils eines der seitlichen Schilde der Treibscheibe mittels eines Wälzlagers drehbar gelagert. Sofern die beiden Lagersockel mindestens zweiteilig ausgeführt sind, können die Teilachsen als massive Schmiedeteile ausgeführt sein. Die Lagersockel werden nach dem Schmieden der Teilachsen an dem Achskörper angebracht. Grundsätzlich ist eine Teilung der Lagersockel in zwei, die Achse jeweils auf einem Umfang von 180 Grad umgebene Teile ausreichend. Werden die Lagersockel einteilig ausgeführt, ist es erforderlich, einen der beiden Flansche jeder Teilachse nachträglich anzubringen, beispielsweise durch aufschrumpfen, was jedoch produktionstechnisch unvorteilhaft ist.On each bearing base each one of the side shields of the traction sheave is rotatably supported by means of a rolling bearing. If the two bearing pedestals are at least two parts, the part axles can be designed as massive forgings. The bearing pedestals are attached to the axle body after forging the part axles. Basically, a division of the bearing base in two, the axis each on a circumference of 180 degrees surrounded parts is sufficient. If the bearing base made in one piece, it is necessary to subsequently attach one of the two flanges of each sub-axis, for example, by shrinking, but this is unfavorable in terms of production technology.
Um die Lagersockel in axialer Richtung auf den Teilachsen zu fixieren, ist jeder Lagersockel vorzugsweise formschlüssig mit einer der beiden Teilachsen verbunden. Der Formschluss kann beispielsweise durch einen den Achskörper jeder Teilachse umgebenden Bund erfolgen, der in eine korrespondierende umlaufende Nut in dem Lagersockel eingreift.In order to fix the bearing pedestals in the axial direction on the sub-axles, each bearing pedestal is preferably connected in a form-locking manner to one of the two sub-axles. The positive connection can be effected, for example, by a collar surrounding the axle body of each partial axle, which engages in a corresponding circumferential groove in the bearing socket.
Zur Abtragung von Querkräften zwischen den inneren Flanschen der Teilachsen sowie zwischen den äußeren Flanschen jeder Teilachse und den Lagerböcken sind die beiden Teilachsen mit den Lagerböcken und an den inneren Flanschen zusätzlich über Achszapfen miteinander verbunden. Die Achszapfen an den beiden inneren Flanschen greifen in einen Durchgang in dem Stegblech ein, dessen Durchmesser dem Außendurchmesser der Achszapfen entspricht. Die Länge der beiden Zapfen ist kleiner als die Dicke des Stegblechs im Bereich des Durchgangs. Die Schraubverbindungen an den Flanschen übertragen sämtliche Momente des Motors sowie alle Biegemomente aufgrund von Eigengewicht, Seilbetriebslast und Seilbruchlast.For the removal of transverse forces between the inner flanges of the sub-axes and between the outer flanges of each sub-axis and the bearing blocks, the two sub-axes are additionally connected to the bearing blocks and on the inner flanges via journals. The journal on the two inner flanges engage in a passage in the web plate whose diameter corresponds to the outer diameter of the journal. The length of the two pins is smaller than the thickness of the web plate in the region of the passage. The screw connections on the flanges transmit all the moments of the motor as well as all Bending moments due to dead weight, rope operating load and rope breaking load.
