Abstract

1. A rotor for beater mills equipped with rows of hammers (10) with parallel axes, a plurality of hammers swing-mounted on sleeves (9), the latter being retained in position between rotor disks (2) by means of bolts (8) passing through the sleeves (9) in an axial direction and secured in the outer rotor disks, thus characterized in that the sleeves (9) are mounted in bearing seats (4, 5) provided on the rotor disks (2) and open in the direction of the rotor axle, whereby the sleeves are secured in the installed position by the bolts (8).

Description

Die Erfindung betrifft einen Rotor für Schlägermühlen mit achsparallelen Reihen von Schlaghämmern, die zu mehreren schwenkbar auf Achsen angeordnet sind, die in Ausnehmungen von Rotorscheiben eingehängt und in eingehängter Lage durch Verriegelungselemente gesichert sind.The invention relates to a rotor for beater mills with axially parallel rows of impact hammers, which are arranged pivotably on several axes, which are suspended in recesses of rotor disks and are secured in the suspended position by locking elements.

Man wählt eine solche Bauart, damit man eine größere Zahl der meist aus flachen Stahlplatten bestehenden Schläger außerhalb der Schlägermühle auf ihrer gemeinsamen Achse aufbringen und sie als Ganzes gegen ein entsprechendes verschlissenes Schlägerpaket austauschen kann, so daß die Stillstandzeiten der SchlägermUhle kurz gehalten werden können.One chooses such a design so that one can apply a larger number of the rackets, which mostly consist of flat steel plates, outside the racket mill on their common axis and can exchange them as a whole for a corresponding worn racket package, so that the downtime of the racket mill can be kept short.

Die bekannten Bauarten der eingangs beschriebenen Art sind jedoch recht kompliziert und dadurch teuer und auch umständlich in der Anwendung. So müssen bei einer Bauart (DE-PS 33 17 070) auf der gemeinsamen Achse zwischen den Schlägern angeordnete Scheiben von der Seite her in entsprechende Ausdrehungen der Rotorscheiben eingeschoben und das Ganze muß dann in axialer Richtung gesichert werden. Bei einer anderen Bauart (DE-PS 7 22 078) werden die in radiale, hakenförmige Ausnehmungen der Rotorscheiben eingehängten Schwenkachsen in diesen Ausnehmungen durch Füllstücke und zweiteilige, die Rotorscheiben umschließende Schellen festgelegt.However, the known types of the type described above are quite complicated and therefore expensive and also cumbersome to use. Thus, in one type (DE-PS 33 17 070), disks arranged on the common axis between the beaters must be inserted from the side into corresponding rotations of the rotor disks and the whole must then be secured in the axial direction. In another design (DE-PS 7 22 078), the pivot axes suspended in radial, hook-shaped recesses of the rotor disks are fixed in these recesses by fillers and two-part clamps surrounding the rotor disks.

Der Erfindung liegt die Aufgabe zugrunde, die Sicherung der Schlägerpakete in den Ausnehmungen der Rotorscheiben zu vereinfachen. Dies wird dadurch erreicht, daß die Achsen, auf denen die Schläger schwenkbar angeordnet sind, als Rohre ausgebildet und als Verriegelungselemente Bolzen vorgesehen sind, die die Rohre durchdringen und in den äußeren Rotorscheiben festgelegt sind.The invention has for its object to simplify the securing of the racket packs in the recesses of the rotor disks. This is achieved in that the axes on which the rackets are pivotally arranged are designed as tubes and bolts are provided as locking elements which penetrate the tubes and are fixed in the outer rotor disks.

Die rohrförmigen Achsen können sich über die gesamte Rotorlänge erstrecken. Es können aber auch zwei oder mehr solcher Achsen axial hintereinander vorgesehen sein. Sie werden aber durch einen sich über die gesamte Rotorlänge erstreckenden Bolzen festgelegt.The tubular axes can extend over the entire rotor length. However, two or more such axes can also be provided axially one behind the other. However, they are fixed by a bolt that extends over the entire length of the rotor.

Die Enden der Achsen werden dabei in seitlich an die betreffenden Rotorscheiben angesetzte, z. B. angeschweißte, zur Rotorachse hin offene Lagerkörper eingehängt. Sollen die Achsen zwischen ihren Enden nochmals gestützt werden, so werden zwischen je zwei benachbarten Rotorscheiben hakenförmige radiale Lagerbleche vorgesehen, die auf der die Rotorachse umschließenden Hohlwelle befestigt, z. B. auf diese aufgeschweißt, sind.The ends of the axes are attached laterally to the rotor disks in question, for. B. welded, open to the rotor axis towards the bearing body. If the axes are to be supported again between their ends, hook-shaped radial bearing plates are provided between every two adjacent rotor disks, which are fastened to the hollow shaft surrounding the rotor axis, for. B. welded onto them.

In der Zeichnung ist ein Ausführungsbeispiel eines Rotors für Schlägermühlen gemäß der Erfindung dargestellt, und zwar zeigt

  • Fig. 1 eine Seitenansicht des Rotors, zur Hälfte im Schnitt, und
  • Fig. 2 eine Stirnansicht des Rotors, teils im Schnitt.
In the drawing, an embodiment of a rotor for beater mills according to the invention is shown and shows
  • Fig. 1 is a side view of the rotor, half in section, and
  • Fig. 2 is an end view of the rotor, partly in section.

Der Rotor besteht aus einer Hohlwelle 1 und aufgeschweißten Rotorscheiben 2. Zwischen je zwei Rotorscheiben sind hakenförmige Stützbleche 3 auf der Hohlwelle befestigt. Auf den einander zugewendeten Seitenflächen der Rotorscheiben 2 sind zur Rotorachse hin offene Lagerkörper 4 angeordnet. Die Stützbleche 3 weisen seitliche Ausnehmungen 5 auf, die in nach außen geschlossene Lagerbuchten 6 führen.The rotor consists of a hollow shaft 1 and welded-on rotor disks 2. Hook-shaped support plates 3 are fastened to the hollow shaft between two rotor disks. On the mutually facing side surfaces of the rotor discs 2 are towards the rotor axis open position rk örper 4 are arranged. The support plates 3 have lateral recesses 5, which lead into closed storage bays 6.

Die Rotorscheiben 2 weisen zentral zu den Lagerkörpern 4 Bohrungen 7 auf, durch die Sicherungsbolzen 8 eingeführt sind. In die Lagerkörper 4 und die Lagerbuchten 6 sind Schlägerpakete eingehängt, die aus einer rohrförmigen Achse 9, schwenkbar darauf angeordneten Schlägern 10 und Abstandsbuchsen 11 bestehen. Die Schlägerpakete 9, 10, 11 sind durch die Sicherungsbolzen 8 in ihrer Lage festgelegt.The rotor disks 2 have bores 7 centrally to the bearing bodies 4, through which locking bolts 8 are inserted. Rackets are suspended in the bearing body 4 and the bearing bays 6 and consist of a tubular axis 9, beaters 10 pivotably arranged thereon and spacer bushings 11. The racket packages 9, 10, 11 are fixed in position by the securing bolts 8.
