Patentanspruch:Claim: Schlagrad für Schlagradmühlen mit je einer durch Stege miteinander verbundenen Naben- und Ringscheibe und an den Stegen auswechselbar befestigten Schlagplatten, wobei die Naben- und Ringscheiben mit nach innen vorstehenden ringförmigen Rändern versehen sind, an denen seitliche Flanschen der Stege nach außen hin anliegen, dadurch gekennzeichnet, daß jeweils zwei in Umfangsrichtung hintereinanderliegende Stege (2) gemeinsame seitliche Flanschen (4) besitzen.Beater wheel for beater mills, each with a hub and ring disk connected to one another by webs and striking plates that are replaceably fastened to the webs, the hub and ring disks are provided with inwardly projecting annular edges, on which side flanges of the webs rest outwards, characterized in that two in each case in the circumferential direction webs (2) lying one behind the other have common lateral flanges (4). Die Erfindung betrifft ein Schlagrad für Schlagradmühlen mit je einer durch Stege miteinander verbundenen Naben- und Ringscheibe und an den Stegen auswechselbar befestigten Schlagplatten, wobei die Naben- und Ringscheiben mit nach innen vorstehenden ringförmigen Rändern versehen sind, an denen seitliche Flanschen der Stege nach außen hin anliegen.The invention relates to a beater wheel for beater mills, each with one connected to one another by webs Hub and ring washer and striking plates that are replaceably attached to the webs, with the Hub and ring disks are provided with inwardly projecting annular edges on which lateral The flanges of the webs rest on the outside. Ein derartiges Schlagrad ist in der DE-PS 10 47 586 beschrieben. Beim Betrieb von Schlagradmühlen mit Schlagrädern dieser Art hat sich gezeigt, daß Verformungen der Stegflanschen und Risse in den Stegen auftreten. Die Verformung der Stegflanschen wird durch die Fliehkräfte verursacht, die auf eine kleine Auflagefläche zwischen Stegflanschen und den Rändern der Ring- und Nabenscheiben einwirken. Die Risse werden im wesentlichen durch die Drehmomente hervorgerufen, die infolge der einseitigen Lage der Schlagplatten zum Stegschwerpunkt entstehen.Such an impact wheel is described in DE-PS 10 47 586. When operating beater mills with Impact wheels of this type have been shown to prevent deformations of the web flanges and cracks in the webs appear. The deformation of the web flanges is caused by the centrifugal forces acting on a small Act on the contact surface between the web flanges and the edges of the ring and hub disks. The cracks are essentially caused by the torques resulting from the one-sided position of the Impact plates are created for the center of gravity of the bridge. Aufgabe der Erfindung ist es, diese Nachteile des bekannten Schlagrades zu beseitigen und ein Schlagrad zu schaffen, bei dem die Stegfliehkräfte auf relativ großen Flächen der Ränder der Naben- und Ringscheiben übertragen werden.The object of the invention is to eliminate these disadvantages of the known striking wheel and a striking wheel to create in which the web centrifugal forces on relatively large areas of the edges of the hub and ring disks be transmitted. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß jeweils zwei in Umfangsrichtung hintereinanderliegende Stege gemeinsame seitliche Flanschen besitzen.According to the invention, this object is achieved in that two in each case are located one behind the other in the circumferential direction Web have common side flanges. ίο Die Fliehkräfte werden dadurch auf eine größere Auflagefläche zwischen den Stegflanschen und den Rändern der Ring- und Nabenscheiben verteilt; dadurch ist die Flächenpressung reduziert, so daß eine Verformung der Stegflanschen vermieden wird. Außerdem wird durch die Zusammenfassung zweier Stege durch gemeinsame seitliche Flanschen die Beanspruchung der Stege durch die Drehmomente weitgehend herabgesetzt und die Gefahr, daß Risse in den Stegen auftreten, vermindert.ίο The centrifugal forces are thereby increased Support surface distributed between the web flanges and the edges of the ring and hub disks; through this the surface pressure is reduced so that deformation of the web flanges is avoided. aside from that the stress is reduced by the combination of two webs through shared lateral flanges the webs largely reduced by the torques and the risk of cracks in the webs occur, diminished. In der Zeichnung und der Beschreibung is! die Erfindung näher erläutert. Es zeigtIn the drawing and the description is! the invention explained in more detail. It shows Fig. 1 eine Ansicht des Schlagrades im Schnitt nach der Linie C-Din Fig. 2,

Zwischen den Flanschen 4 der Naben- und Ringscheiben 1, 3 sind die Panzerbleche 5 angeordnet. Zwischen den Stegen 2 sind die Flanschen 4 mit den Panzerblechen 6 versehen.so the hub and ring disks i, 3 are in contact. The armor plates 5 are arranged between the flanges 4 of the hub and ring disks 1, 3. The flanges 4 are provided with the armor plates 6 between the webs 2.
