Description

Rotor für eine ZerkleinerungsmaschineRotor for a shredding machine
Technisches GebietTechnical field
Die Erfindung betrifft gemäß dem Oberbegriff des Anspruches 1 einen Rotor für eine Zerkleinerungsmaschine, der aus mehreren auf einer Welle drehfest aufgesteckten Scheiben, aus zwischen diesen verteilt angeordneten drehbeweglichen Hämmern und den Rotor gegen Verschleiß abdeckenden Schutzkappen besteht.The invention relates, according to the preamble of claim 1, to a rotor for a comminution machine, which consists of a plurality of disks which are non-rotatably fitted on a shaft, of rotatable hammers distributed between them, and of the protective caps covering the rotor against wear.
Stand der TechnikState of the art
Derartige Rotoren wurden bereits mit der DE 26 05 751 AI bekannt und schließlich nach der DE 43 43 801 AI zu einem Schleißteilsystem weiterentwickelt.Such rotors were already known from DE 26 05 751 AI and finally further developed according to DE 43 43 801 AI into a wearing part system.
Bei differenzierter Betrachtung der den Rotor gegen Verschleiß abdeckenden Schutzkappen kommt den äußeren Schutzkappen, die die äußeren Scheiben des Rotors abdecken, eine besondere Bedeutung im System des Rotors als Werkzeug und zugleich zu schützendes System der Zerkleinerungsmaschine zu.When the protective caps covering the rotor against wear are considered in a differentiated manner, the external protective caps, which cover the outer disks of the rotor, are of particular importance in the system of the rotor as a tool and at the same time a system of the shredding machine to be protected.
So sind zwar die äußeren Schutzkappen zunächst wie die anderen Schutzkappen als inaktive Schleißteile einzuordnen, jedoch haben sie von jenen darüber hinausgehende Funktionen infolge spezifisch wirkender Kräfte zu erfüllen.Although the outer protective caps are initially to be classified as inactive wear parts, like the other protective caps, they have to perform additional functions as a result of specifically acting forces.
Bisher waren die äußeren Schutzkappen lose nur gegen die Fliehkraft und gegen von außen einwirkende radial gerichtete Kräfte über die Hammerachse gehalten. Ein an der äußeren Scheibe befestigtes, vorbenutztes, sogenanntes Verschluß stück sicherte die Lage der Hammerachse und deckte zugleich den die Scheibe übergreifenden Steg der Schutzkappe ab. Wenn auch diese konstruktive Lösung im allgemeinen den Anforderungen der Praxis im Zerkleinerungsprozeß standhielt, so gab es doch infolge der vom Hammer und von der Hammerachse zugleich auf das Verschlußstück und die Kappe einwirkenden Kräftemomente Probleme, die letztlich relativ kostenaufwendige Schäden nicht ausschloß. Darüber hinaus zeigt die US 42 22 530, daß die die äußeren Scheiben des Rotors abdeckenden Schutzkappen von den Kräften der Hämmer und der Hammerachsen und von den durch die Hämmer direkt auf die äußeren Schutzkappen eingeleiteten Kräften entkoppelt sind, wobei die Schutzkappen die Scheibe umgreifen und mittels mindestens eines Verbindungselementes an der Scheibe kraftschlüssig befestigt sind.Previously, the outer protective caps were held loosely only against the centrifugal force and against radially directed forces acting from outside via the hammer axis. A pre-used, so-called closure piece attached to the outer pane secured the position of the hammer axis and at the same time covered the web of the protective cap which overlaps the pane. Even if this constructive solution generally withstood the requirements of practice in the shredding process, there were problems due to the moments of force acting simultaneously on the closure piece and the cap from the hammer and the hammer axis, which ultimately did not exclude relatively costly damage. In addition, US 42 22 530 shows that the protective caps covering the outer disks of the rotor are decoupled from the forces of the hammers and the hammer axes and from the forces introduced directly onto the outer protective caps by the hammers, the protective caps engaging around the disc and by means of at least one connecting element are non-positively attached to the disc.
Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt die Aufgabe zugrunde, einen Rotor für eine Zerkleinerungsmaschine zu schaffen, der aus mehreren, auf einer Welle drehfest aufgesteckten Scheiben und aus zwischen diesen verteilt angeordneten Hämmern, die auf parallel-exzentrisch zu der Welle durch die Scheiben geführte Hammerachsen drehbeweglich gelagert sind und zumindest die dem sekundären Verschleiß ausgesetzten Teile des Rotors mit ihrem kreisbogensegmentförmigen Teil abdeckenden Schutzkappen besteht, die mit ihren Lagernaben zwischen den Scheiben auf besagten Hammerachsen befestigt sind. Dabei ist der Rotor durch die Schutzkappen mit ihren kreisbogensegmentförmigen Teilen zu einem im wesentlichen walzenförmigen Mantel mit gewünscht versetzt zueinander angeordneten Durchbrüchen zum Durchschwingen der Hämmer zu bilden, wobei die störenden Kräfte der Hämmer und Hammerachsen weitgehend ausgeschaltet und eine materialsparende sowie kostengünstige Befestigung der äußeren Schutzkappen an den Scheiben gewährleistet werden.The invention has for its object to provide a rotor for a comminution machine, which consists of several disks rotatably mounted on a shaft and from between distributed hammers, which are rotatably mounted on parallel to the shaft eccentrically through the disks hammer axes and at least the parts of the rotor exposed to secondary wear with their circular segment-shaped part covering protective caps, which are fastened with their bearing hubs between the disks on said hammer axes. The rotor is to be formed by the protective caps with their circular segment-shaped parts to form an essentially roller-shaped casing with perforations for swinging through the hammers which are arranged offset with respect to one another, the disturbing forces of the hammers and hammer axes largely being eliminated and a material-saving and inexpensive fastening of the outer protective caps the discs are guaranteed.
Diese Aufgabe wird beim gattungsgemäßen Rotor durch die Merkmale des Kennzeichens des Anspruches 1 gelöst. Die die äußeren Scheiben des Rotors abdeckenden Schutzkappen sind dabei von den Kräften der Hammerachsen und von den durch die Hämmer direkt auf die äußeren Schutzkappen eingeleiteten Kräften so in Abgrenzung zum Stand der Technik gemäß US 42 22 530 entkoppelt, daß die den Seitenkräften der Hämmer ausgesetzten äußeren Schutzkappen sowohl den äußeren Rand der Scheiben mit ihrem jeweiliegen Steg als auch über einen ringsegmentförmigen Vorsprung einen Absatz der Scheibe umgreifen und zugleich mittels mindestens eines Verbindungselementes wie Imbusschraube an der Scheibe formschlüssig angebracht sind. Andererseits sind die an den inneren Schutzkappen grenzenden äußeren Schutzkappen mittels mindestens eines Verbindungselementes wie Imbusschraube an der äußeren Scheibe kraftschlüssig befestigt. Dabei sichert und begrenzt ein ebenfalls an der Scheibe direkt befestigtes Verschlußstück die axiale Lage der jeweiligen Hammerachse in der Scheibe.This object is achieved in the generic rotor by the features of the characterizing part of claim 1. The protective caps covering the outer disks of the rotor are decoupled from the forces of the hammer axes and from the forces introduced by the hammers directly onto the outer protective caps in delimitation from the prior art in accordance with US Pat. No. 4,222,530 that the external forces exposed to the side of the hammers Protective caps encompass both the outer edge of the disks with their respective web and a shoulder of the disk via a ring-segment-shaped projection and at the same time are positively attached to the disk by means of at least one connecting element such as an Allen screw. On the other hand, the outer ones bordering the inner protective caps Protective caps are non-positively attached to the outer pane by means of at least one connecting element such as an Allen screw. A locking piece, which is also attached directly to the disk, secures and limits the axial position of the respective hammer axis in the disk.
Damit wird im Sinne der Aufgabenstellung erreicht, daß die den Seitenkräften der Hämmer ausgesetzten äußeren Schutzkappen von den bisher zusätzlichen Kräften der Hammerachsen befreit sind und eine sichere, formschlüssige Verbindung erhalten. Die Hammerachsen sind allein durch die Verschlußstücke gesichert. Die den inneren Schutzkappen anliegenden äußeren Schutzkappen, bei denen keine wesentliche kräftemäßige Beeinflussung von innerer Schutzkappe zu äußerer Schutzkappe vorliegt, besitzen eine ausreichende kraftschlüssige Verbindung.It is achieved in the sense of the task that the outer protective caps exposed to the lateral forces of the hammers are freed from the previously additional forces of the hammer axes and receive a secure, form-fitting connection. The hammer axes are secured solely by the locking pieces. The outer protective caps which lie against the inner protective caps and in which there is no significant force influence from the inner protective cap to the outer protective cap have an adequate non-positive connection.
Überraschend hat sich gezeigt, daß diese erfindungsgemäß weiterentwickelte Kräfteentkopplung sowohl konstruktive und technologische Vorteile beim Hersteller als auch technologische Vorteile beim Betreiber und eine bruchsichere Lösung insgesamt bewirkt.Surprisingly, it has been shown that this decoupling of forces developed according to the invention brings about both constructive and technological advantages for the manufacturer as well as technological advantages for the operator and an unbreakable solution as a whole.
So liegen die Vorteile auch darin, daß in der Lagerhaltung von erfindungsgemäß ausgeführten Ersatz- und Austauschteilen und mit den daraus resultierenden optimierbaren Wartungsintervallen kostenaufwendige Umlaufbestände reduziert werden können.The advantages also lie in the fact that costly circulating stocks can be reduced in the storage of spare and replacement parts designed according to the invention and with the resultant optimizable maintenance intervals.
Diese vorteilhaften Wirkungen unterstützen die weiteren erfindungsgemäßen Merkmale, wenn zur Erhaltung einer praktisch ebenen Außenfläche der Scheiben die Stege der äußeren Schutzkappen Aussparungen aufweisen, die zumindest zu Teilen die Verschlußstücke umgreifen. Dies wird noch dadurch vervollkommnet, daß die Stege und Verschlußstücke in deren Konturen ähnliche Aussparungen an der Außenseite der Scheibe eingelassen sind, um keine hervorspringenden Teile zu bilden. Diese entsprechende Ausbildung wird technologisch günstig dadurch erreicht, daß auf einer planen Scheibe eine weitere Scheibe befestigt wird, die periphere Konturen aufweist, die im wesentlichen den tangierenden Konturen der Stege und der Verschlußstücke folgen, wobei diese Konturen zu der ersten Scheibe Auslassungen bilden, in die die Verschlußstücke und die Stege eine praktisch ebene Fläche bildend eingelassen sind. Für den verschleißintensiven Betrieb des Rotors ist es zweckmäßig, wenn die formschlüssige Anbringung der Stege der den Seitenkräften der Hämmer ausgesetzten Schutzkappen an die Scheibe mittels der Befestigungselemente wie Imbusschrauben so erfolgt, daß diese mit ihren Köpfen auf den Gewindebohrungen in der Scheibe aufsitzen, wobei zwischen dem jeweiligen Kopf sowie dessen flanschartigen Ansatz und der entsprechend abgesetzten Bohrung im Steg ein Spiel besteht.These advantageous effects support the further features according to the invention if, in order to maintain a practically flat outer surface of the panes, the webs of the outer protective caps have cutouts which at least partially encompass the closure pieces. This is further perfected by the fact that the webs and closure pieces are recessed in their contours similar recesses on the outside of the disc, so as not to form protruding parts. This corresponding training is achieved in a technologically advantageous manner in that a further disk is attached to a flat disk, which has peripheral contours which essentially follow the tangent contours of the webs and the closure pieces, these contours forming omissions to the first disk in which the closure pieces and the webs are embedded to form a practically flat surface. For the wear-intensive operation of the rotor, it is expedient if the form-fitting attachment of the webs of the protective caps exposed to the lateral forces of the hammers to the disk is carried out by means of the fastening elements such as Allen screws in such a way that their heads rest on the threaded holes in the disk, between which each head and its flange-like approach and the correspondingly offset hole in the web there is a game.
Bei der hingegen kraftschlüssigen Befestigung der Stege der an den inneren Schutzkappen grenzenden Schutzkappen mittels der Befestigungselemente wie Imbusschrauben sitzt der jeweilige flanschartige Ansatz des Kopfes in der entsprechend abgesetzten Bohrung auf.In contrast, when the webs of the protective caps bordering on the inner protective caps are non-positively fastened by means of the fastening elements such as Allen screws, the respective flange-like attachment of the head rests in the correspondingly offset bore.
Um die Befestigungselemente wie Imbusschrauben an den Innenseiten vor durch den Verschleißprozeß bedingten Verformungen zu schützen, werden von dieser Seite Verbindungselemente eingesetzt, vorrangig hutförmige Muttern, formschlüssig oder kraftschlüssig gesichert, deren Hutoberfläche mit der Innenfläche der Scheibe eine Ebene bildet.To protect the fastening elements such as Allen screws on the inside from deformations caused by the wear process, connecting elements are used from this side, primarily hat-shaped nuts, positively or non-positively secured, the hat surface of which forms a plane with the inner surface of the washer.
Die erfindungsgemäßen Merkmale stellen in ihrer kombinierten Komplexität und funktioneil verschmolzenen Einheit einen Rotor dar, der einen deutlichen Qualitätsvorsprung bezüglich seiner Konstruktion sowie seiner technologischen Herstellung und Anwendung schafft.In their combined complexity and functionally fused unit, the features according to the invention represent a rotor which creates a clear quality advantage in terms of its design, as well as its technological manufacture and application.
Die Erfindung wird nachstehend in einem Ausführungsbeispiel erläutert.The invention is explained below in an exemplary embodiment.

Bester Weg zur Ausführung der ErfindungBest way to carry out the invention
In den Fig. 1 und 2 ist ein Rotor 1 für einen Hammerbrecher dargestellt, der im wesentlichen aus mehreren auf einer Welle 2 drehfest aufgesteckten Scheiben 3 und aus zwischen diesen verteilt angeordneten Hämmern 4 besteht. Die Hämmer 4 sind auf parallel zu der Welle 2 durch die Scheiben 3 geführte Hammerachsen 5 drehbeweglich gelagert. Zumindest die dem sekundären Verschleiß ausgesetzten Teile des Rotors sind mit den kreisbogensegmentförmigen Teilen 6.4 der Schutzkappen 6 abgedeckt. Diese Teile 6.4 bilden einen im wesentlichen walzenförmigen Mantel 7 mit gewünscht versetzt zueinander angeordneten Durchbrüchen 7.1 zum Durchschwingen der Hämmer 4.1 and 2, a rotor 1 for a hammer crusher is shown, which essentially consists of a plurality of disks 3 mounted non-rotatably on a shaft 2 and of hammers 4 distributed between them. The hammers 4 are rotatably mounted on hammer axes 5 which are guided parallel to the shaft 2 through the disks 3. At least the parts of the rotor that are exposed to secondary wear are covered with the circular segments 6.4 of the protective caps 6. These parts 6.4 form an essentially roller-shaped casing 7 with perforations 7.1 arranged to be offset with respect to one another for swinging through the hammers 4.
Erfindungsgemäß werden nach Fig. 2 und 3 die die äußeren Scheiben 3.1 des Rotors 1 abdeckenden Schutzkappen 6.1 von den Kräften der Hämmer 4 und der Hammerachsen 5 sowie von den durch die Hämmer 4 direkt auf die Schutzkappen 6.1 eingeleiteten Kräfte entkoppelt. Dabei sind die Schutzkappen 6.1 mittels den äußeren Rand der Scheiben 3.2 nach außen umgreifenden Stegen 6.2 direkt an den Scheiben 3.1 befestigt. Der jeweilige Steg 6.1 weist eine Aussparung 6.3 (Fig. 2, 3 und 4) auf, die ein ebenfalls an der Scheibe 3.1 direkt befestigtes Verschlußstück 8 teilweise umfaßt (Fig. 2), welches die axiale Lage der jeweiligen Hammerachse 5 in der Scheibe 3.1 begrenzt und sichert.According to the invention, according to FIGS. 2 and 3, the protective caps 6.1 covering the outer disks 3.1 of the rotor 1 are decoupled from the forces of the hammers 4 and the hammer axes 5 and from the forces introduced by the hammers 4 directly onto the protective caps 6.1. The protective caps 6.1 are fastened directly to the disks 3.1 by means of the webs 6.2 encompassing the outer edge of the disks 3.2. The respective web 6.1 has a cutout 6.3 (FIGS. 2, 3 and 4) which partially includes a closure piece 8 which is also directly attached to the disk 3.1 (FIG. 2) and which defines the axial position of the respective hammer axis 5 in the disk 3.1 limits and secures.
Entsprechend Fig. 3a, b ist die den Seitenkräften der Hämmer 4 ausgesetzte Schutzkappe 6.1 über einen ringsegmentförmigen Vorsprung 6.5, der in einen Absatz 3.2 der Scheibe 3.1 eingreift, und mittels mindestens einer Imbusschraube als Verbindungselement 10, die mit ihrem Kopf auf der Gewindebohrung in der Scheibe 3.1 aufsitzt, formschlüssig verbunden. Dazu besteht zwischen dem Kopf sowie dessen flanschartigen Ansatz und der entsprechend abgesetzten Bohrung im Steg 6.2 ein Spiel.3a, b is the protective cap 6.1 exposed to the lateral forces of the hammers 4 via a ring segment-shaped projection 6.5 which is in a shoulder 3.2 of the disk 3.1 engages, and positively connected by means of at least one Allen screw as a connecting element 10, which sits with its head on the threaded bore in the disk 3.1. There is a game between the head and its flange-like approach and the correspondingly offset hole in the web 6.2.
Hingegen ist gemäß Fig. 4a, b die an der betreffenden inneren Schutzkappe 6 grenzende Schutzkappe 6.1 mit ihrem Steg 6.2 kraftschlüssig an der Scheibe 3.1 durch mindestens eine Imbusschraube als Verbindungselement 10 befestigt, die deshalb mit ihrem flanschartigen Ansatz des Kopfes in der entsprechend abgesetzten Bohrung im Steg 6.2 aufsitzt.4a, b, the protective cap 6.1 bordering on the relevant inner protective cap 6 is non-positively fastened with its web 6.2 to the disk 3.1 by means of at least one Allen screw as a connecting element 10, which therefore has a flange-like attachment of the head in the correspondingly offset bore in the Web 6.2 sits on.
Zur Vermeidung von störenden Verformungen der Imbusschrauben als Verbindungselement 10 greifen diese gemäß Fig. 5 in hutförmige Muttern als Befestigungselemente 9 ein, die von der anderen Seite in die Scheibe 3.1 eingesetzt und formschlüssig oder kraftschlüssig gesichert sind.To avoid disturbing deformations of the Allen screws as the connecting element 10, they engage according to FIG. 5 in hat-shaped nuts as fastening elements 9, which are inserted into the disk 3.1 from the other side and are positively or non-positively secured.
Eine technologisch günstige Ausführung nach Fig. 1 und 2 sieht vor, daß mit der äußeren Scheibe 3.1 eine Scheibe 3.3 verbunden ist, die den in der Fig. 2 sichtbaren Konturen der Stege 6.2 und der Verschlußstücke 8 folgt, welche so in den gegenüber der Scheibe 3.1 entstandenen Aussparungen die Verschlußstücke 8 und die Stege 6.2 eingelassen sind, daß eine praktisch ebene Fläche ohne hervorspringende Teile entsteht.A technologically favorable embodiment according to FIGS. 1 and 2 provides that a disk 3.3 is connected to the outer disk 3.1, which follows the contours of the webs 6.2 and the closure pieces 8 visible in FIG. 2, which in the opposite of the disk 3.1 resulting recesses, the locking pieces 8 and the webs 6.2 are embedded, that a practically flat surface is created without protruding parts.
