Abstract
Description
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.According to the preamble of claim 1, the invention relates to a rotor for a Shredding machine, which consists of several disks rotatably attached to a shaft, from rotatable hammers distributed between these and the rotor against Protective caps covering wear exist.
Derartige Rotoren wurden bereits mit der DE 26 05 751 A1 bekannt und schließlich nach der
DE 43 43 801 A1 zu einem Schleißteilsystem weiterentwickelt.
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.
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.
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 Verschlußstück 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. Such rotors were already known from DE 26 05 751 A1 and finally developed further into a wear part system according to DE 43 43 801 A1.
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.
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.
So far, 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 previously 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. Although 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 preclude relatively costly damage.
Die GB 2 143 748 A2 offenbart einen Rotor für eine Zerkleinerungsmaschine mit mehreren
auf einer Welle drehfest aufgesteckten Scheiben und 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 kreisbogenförmigen Teilen abdeckenden Schutzkappen, die
mit ihrer Lagernabe zwischen den Scheiben befestigt sind, wobei der Rotor durch die
Schutzkappen mit ihren kreisbogensegmentförmigen Teilen einen im wesentlichen
walzenförmigen Mantel mit gewünscht versetzt zueinander angeordneten Durchbrüchen zum
Durchschwingen der Hämmer bildet, wobei die äußeren Schutzkappen von den Kräften der
Hämmer und der Hammerachsen entkoppelt sind, und wobei ein an der Endscheibe direkt
befestigtes Verschlußstück die axiale Lage der jeweiligen Hammerachse in der Endscheibe
begrenzt und sichert.
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.In addition, US 42 22 530 shows that covering the outer discs of the rotor Caps from the forces of the hammers and hammer axes and from those by Hammers are decoupled forces directly applied to the outer protective caps, the Protective caps encompass the pane and attach it by means of at least one connecting element the disc are non-positively attached.
Der Erfindung liegt die Aufgabe zugrunde, einen Rotor für eine Zerkleinerungsmaschine zu schaffen mit mehreren, auf einer Welle drehfest aufgesteckten Scheiben und 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, wobei der Rotor durch die Schutzkappen mit ihren kreisbogensegmentförmigen Teilen einen im wesentlichen walzenförmigen Mantel mit gewünscht versetzt zueinander angeordneten Durchbrüchen zum Durchschwingen der Hämmer bildet, wobei die äußeren Schutzkappen von den Kräften der Hämmer und Hammerachsen entkoppelt sind, wobei ein an der Endscheibe direkt befestigtes Verschlußstück die axiale Lage der jeweiligen Hammerachse in der Endscheibe begrenzt und sichert und die Befestigung der äußeren Schutzkappen an den Scheiben auf eine materialsparende sowie kostengünstige Weise realisiert wird.The invention has for its object to a rotor for a shredding machine create with several disks that are fixed on a shaft and between them distributed hammers arranged on parallel eccentric to the shaft through the discs guided hammer axes are rotatably mounted, and at least the secondary Parts of the rotor exposed to wear with their circular segment-shaped part protective caps that exist with their bearing hubs between the washers said hammer axes are attached, the rotor through the protective caps with their circular segment-shaped parts with a substantially cylindrical shell Desired offset openings to swing through the Forms hammers, with the outer caps by the forces of the hammers and Hammer axes are decoupled, one directly attached to the end plate Breech piece limits the axial position of the respective hammer axis in the end plate and secures and the attachment of the outer protective caps to the washers on a material-saving and cost-effective way is realized.
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 Inbusschraube an der Scheibe formschlüssig angebracht sind. Andererseits sind die an den inneren Schutzkappen grenzenden äußeren Schutzkappen mittels mindestens eines Verbindungselementes wie Inbusschraube 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 task is performed in the generic rotor by the features of the characteristic of Claim 1 solved. The protective caps covering the outer discs of the rotor are thereby from the forces of the hammer axles and from those through the hammers directly onto the external protective cap forces in contrast to the state of the art US 42 22 530 decouples that the exposed to the side forces of the hammers Protective caps both the outer edge of the panes with their respective web as well grasp a shoulder of the disc via a ring segment-shaped projection and at the same time by means of at least one connecting element such as an Allen screw on the pane are positively attached. On the other hand, they are on the inner protective caps bordering outer protective caps by means of at least one connecting element such as Allen screw non-positively attached to the outer disc. It secures and limits the axial position of the respective also fastened to the disc Hammer axis in the disc.
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 side forces of the hammers exposed outer protective caps from the previously additional forces of the hammer axes are exempt and receive a secure, positive connection. The hammer axes are secured only by the locking pieces. The ones lying against the inner protective caps outer protective caps, in which there is no significant influence on the internal force Protective cap to the outer protective cap is present, have sufficient 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 force decoupling, which has been further developed according to the invention both constructive and technological advantages at the manufacturer as well 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 in the storage of those designed according to the invention Spare and exchange parts and with the resulting optimizable maintenance intervals costly current stocks can be reduced.
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.These advantageous effects support the further features according to the invention if the webs of the outer protective caps to maintain a practically flat outer surface of the panes Have recesses which at least partially encompass the closure pieces. This is further perfected by the fact that the webs and closure pieces in their Contour-like recesses on the outside of the pane are recessed to none protruding parts to form. This corresponding training becomes technological Favorably achieved in that a further disc is attached to a flat disc has peripheral contours that essentially the tangent contours of the webs and follow the locking pieces, these contours forming omissions to the first disc, in which the closure pieces and the webs form a practically flat surface are.
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 Inbusschrauben 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.For the wear-intensive operation of the rotor, it is useful if the positive Attach the webs of the protective caps exposed to the side forces of the hammers to the Washer by means of fasteners such as Allen screws so that this with their Heads sit on the threaded holes in the washer, between the respective 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 Inbusschrauben sitzt der jeweilige flanschartige Ansatz des Kopfes in der entsprechend abgesetzten Bohrung auf. On the other hand, the webs are non-positively attached to the inner protective caps adjacent protective caps by means of fastening elements such as Allen screws each flange-like approach of the head in the correspondingly stepped bore.
Um die Befestigungselemente wie Inbusschrauben 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 the fasteners such as Allen screws on the inside before through the To protect deformations caused by the wear process, connecting elements are used on this side used, primarily hat-shaped nuts, positive or non-positive secured, the hat surface forms a plane with the inner surface of the disc.
Die erfindungsgemäßen Merkmale stellen in ihrer kombinierten Komplexität und funktionell verschmolzenen Einheit einen Rotor dar, der einen deutlichen Qualitätsvorsprung bezüglich seiner Konstruktion sowie seiner technologischen Herstellung und Anwendung schafft.The features according to the invention represent in their combined complexity and functional fused unit represents a rotor that has a clear quality advantage in terms of its construction as well as its technological manufacture and application.
