Description

Die Erfindung bezieht sich auf ein Schleuderrad für Strahlmittelanlagen mit einem Leitscheibenrad und mit an dem Leitscheibenrad mit Hilfe von Spannelementen als Arretierungen befestigten Wurfschaufeln, deren Vor-und Rückseite gleich, symmetrisch zu ihrer Längsachse und zu einer senkrecht zur Längsachse in der Schaufelebene verlaufenden Querachse ausgebildet ist, und die Ausnehmungen für die Aufnahme der Spannelemente aufweisen.The invention relates to a centrifugal wheel for abrasive systems with a guide pulley wheel and with throwing vanes fastened to the guide pulley wheel with the aid of tensioning elements as detents, the front and rear sides of which are identical, symmetrical to their longitudinal axis and to a transverse axis running perpendicular to the longitudinal axis in the blade plane , and have the recesses for receiving the clamping elements.

Bei dem in der EU-OS 79 100 943 beschriebenen Schleuderrad ist jede Wurfschaufel spiegelsymmetrisch zu zwei aufeinander senkrechten Achsen ausgebildet. Da jede Wurfschaufel in einer dieser Achsen, nämlich in der Querachse, auch Ausnehmungen für die Aufnahme der Arretierung an dem Leitscheibenrad aufweist, ist ein vierfacher Einsatz der Wurfschaufeln möglich: Jede Wurfschaufel kann um 180° sowohl um ihre Längsachse als auch um ihre Querachse gedreht und in jeder dieser Lagen in das Leitscheibenrad eingesetzt werden. Das Schleuderrad kann in beiden Drehrichtungen bewegt werden. Das Leitscheibenrad erlaubt durch die Symmetrie über die Querachse eine Verdrehung des Radkörpers mit den Schaufeln um 180° mit der Möglichkeit für Rechts- und Linksumlauf. Der gleiche Effekt wird durch Umsetzen der Spannelemente für die Arretierung jeweils auf die der Drehrichtung abgewendetEnSeite der Wurfschaufeln für zwei Drehrichtungen des Schleuderrads erzielt. So ausgestaltete Wurfschaufeln sind optimal nutzbar. Mit ihnen lassen sich die maximal möglichen Standzeiten erzielen. Das beschriebene Prinzip setzt für ein Leitscheibenrad bestimmter Abmessung Wurfschaufeln bestimmter Abmessung, insbesondere bestimmter Länge, voraus. Wird ein abweichender Abwurfdurchmesser für das Strahlgut verlangt, sind also längere oder kürzere Schaufeln notwendig oder erwünscht, sind bei Beibehaltung des genannten Prinzips angepaßte Leitscheibenräder erforderlich.In the centrifugal wheel described in EU-OS 79 100 943, each throwing blade is mirror-symmetrical to two mutually perpendicular axes. Since each throwing blade in one of these axes, namely in the transverse axis, also has recesses for receiving the locking device on the guide disc wheel, the throwing blades can be used four times: each throwing blade can be rotated by 180 ° both about its longitudinal axis and about its transverse axis and can be inserted in the guide disc wheel in each of these positions. The centrifugal wheel can be moved in both directions. Due to the symmetry about the transverse axis, the guide pulley wheel allows the wheel body with the blades to be rotated by 180 ° with the possibility of right and left rotation. The same effect is achieved by implementing the clamping elements for the locking on each side of the throwing vanes for two directions of rotation of the centrifugal wheel. Throwing blades designed in this way can be optimally used. The maximum possible downtimes can be achieved with them. The principle described presupposes throwing blades of a certain dimension, in particular a certain length, for a guide disk wheel of a certain dimension. If a different discharge diameter is required for the blasting material, ie longer or shorter blades are necessary or desirable, adapted guide pulley wheels are required while maintaining the principle mentioned.

Der Erfindung liegt die Aufgabe zugrunde, ein Schleuderrad zu schaffen, bei dem unter Beibehaltung der vollständigen Symmetrie und damit der Möglichkeit des vierfachen Einsatzes jeder Wurfschaufel ein und dasselbe Leitscheibenrad mit unterschiedlich langen Wurfschaufeln bestückt werden kann. Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß in jeder Wurfschaufel die Ausnehmungen paarweise spiegelbildlich im Abstand von der Querachse angeordnet sind.The invention has for its object to provide a centrifugal wheel in which, while maintaining the full symmetry and thus the possibility of four times the use of each throwing blade, one and the same guide disc wheel can be equipped with throwing blades of different lengths. This object is achieved according to the invention in that in each throwing blade the recesses are arranged in mirror image pairs at a distance from the transverse axis.

Bei der Erfindung können in ein und dasselbe Leitscheibenrad Wurfschaufeln unterschiedlicher Länge eingesetzt werden: Die "Normallänge" ergibt sich, wenn die Ausnehmungen für die Aufnahme der Spannelemente in der Symmetrie-Querachse liegen. Zu dieser Symmetrie-Querachse weisen kürzere und längere Wurfschaufeln gemäß der Erfindung die Ausnehmungen paarweise spiegelbildlich auf. Die kürzeren und längeren Wurfschaufeln werden ebenso in das Leitscheibenrad eingesetzt wie die Wurfschaufeln mit "Normallänge". Wegen der ortsfesten Spannelemente einerseits und des Abschlusses mit dem Innendurchmesser des Leitscheibenrads andererseits benötigen kürzere und längere Wurfschaufeln Ausnehmungen für die Aufnahme der Spannelemente in einem Abstand von ihrer Stirnkante, der gleich dem Abstand der Spannelemente vom Innendurchmesser des Leitscheibenrads ist. Die vierfache Verwendbarkeit ergibt sich dadurch, daß die weiteren Ausnehmungen mit der Querachse als Spiegelebene vorgesehen sind. Nach dem Einbau in das Leitscheibenrad liegen die weiteren Ausnehmungen bezogen auf den Innendurchmesser des Leitscheibenrads bei kürzeren Schaufeln auf der zugewandten, bei längeren Schaufeln auf der abgewandten Seite der Spannelemente.In the invention, throwing blades of different lengths can be used in one and the same guide disc wheel: the "normal length" is obtained when the recesses for receiving the tensioning elements lie in the transverse axis of symmetry. In relation to this transverse axis of symmetry, shorter and longer throwing blades according to the invention have the recesses in pairs in mirror image. The shorter and longer throwing blades are used in the guide disc wheel as well as the throwing blades with "normal length". Because of the fixed clamping elements on the one hand and the closure with the inner diameter of the guide disc wheel on the other hand, shorter and longer throwing blades require recesses for receiving the clamping elements at a distance from their front edge, which is equal to the distance of the clamping elements from the inner diameter of the pulley wheel. The fourfold usability results from the fact that the further recesses are provided with the transverse axis as a mirror plane. After installation in the guide pulley wheel, the further recesses, based on the inner diameter of the guide pulley wheel, lie on the facing side of the clamping elements in the case of shorter blades and on the opposite side of the clamping elements in the case of longer blades.

Ein Zahlenbeispiel soll die vorgenannten Ausführungen verdeutlichen: Ein Schleuderrad soll bei Abwurfdurchmessern von 560 mm, 450 mm und von 340 mm betrieben werden können. Bei einem Innendurchmesser des Leitscheibenrads von 130 mm werden für den mittleren Abwurfdurchmesser Schaufeln einer Länge von 160 mm verwendet, die die Ausnehmungen für die Aufnahme der Spannelemente in der Symmetrie-Querachse aufweisen. Für den kleineren/größeren Abwurfdurchmesser werden Schaufeln einer Länge von 105 mm/215 mm verwendet, die zu beiden Seiten von der Symmetrie-Querachse im Abstand von 27,5 mm Ausnehmungen für die Aufnahme der Spannelemente aufweisen.A numerical example should clarify the above-mentioned explanations: A centrifugal wheel should be able to be operated with discharge diameters of 560 mm, 450 mm and 340 mm. With an inner diameter of the guide disc wheel of 130 mm, blades with a length of 160 mm are used for the average discharge diameter, which have the recesses for receiving the tensioning elements in the transverse symmetry axis. For the smaller / larger discharge diameter, blades with a length of 105 mm / 215 mm are used, which have recesses on both sides of the symmetry transverse axis at a distance of 27.5 mm for receiving the clamping elements.

Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben. Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen:

  • Fig. 1 die Ansicht einer kurzen Wurfschaufel;
  • Fig. 2 einen Querschnitt durch die Wurfschaufel entlang der Schnittlinie II-II in Fig. 1;
  • Fig. 3 einen Längsschnitt durch die Wurfschaufel entlang der Schnittlinie III-III in Fig. 1.
Embodiments of the invention are specified in the subclaims. An embodiment of the invention is shown in the drawing and will be described in more detail below. Show it:
  • 1 shows the view of a short throwing blade;
  • 2 shows a cross section through the throwing blade along the section line II-II in Fig. 1.
  • 3 shows a longitudinal section through the throwing blade along section line III-III in FIG. 1.

Eine bei der Erfindung verwendete Wurfschaufel 1 besteht im wesentlichen aus einer rechteckigen Grundplatte 2, deren beide Seiten als Strahlmittellauffläche dienen. An jeder Längskante weist die Grundplatte 2 einen rippenförmigen Seitenrand 3 auf. Der Querschnitt der Wurfschaufel 1 erhält dadurch die Form eines Doppel-T. Die Übergänge von der Grundplatte 2 zu den Seitenrändern 3 sind abgerundet, wie es die Fertigungsverfahren des Schmiedens oder Gießens verlangen. Paarweise spiegelbildlich im Abstand von einer mittig verlaufenden Querachse A-A weist jeder Seitenrand auf jeder Seite Ausnehmungen 4 auf, die im wesentlichen halbkreisförmig ausgebildet sind. Die Ausnehmungen 4 sind sowohl auf der Vorderseite als auch auf der Rückseite der Wurfschaufel 1 vorgesehen. Die in derselben Querachse vorgesehenen Ausnehmungen 4 dienen der Befestigung der Wurfschaufel an einem Leitscheibenrad. Wird zum Beispiel die Wurfschaufel mit der in Fig. 1 rechten Stirnseite nach innen in das Leitscheibenrad eingebracht, greifen die Spannelemente in die in Fig. 1 links dargestellten Ausnehmungen. Das gleiche gilt, wenn die Wurfschaufel um die Längsachse B-B um 180° geschwenkt wird. Wird dagegen die Wurfschaufel um die Querachse A-A um 1800 geschwenkt, greifen die Spannelemente in die - dann an der Stelle der ersten Ausnehmungen befindlichen - spiegelbildlich angeordneten Ausnehmungen. Die rippenförmigen Seitenränder 3 sind an den Stirnseiten der Wurfschaufel 1 und in der Querachse A-A mit nach außen weisenden Verstärkungsrippen 5 versehen.A throwing scoop 1 used in the invention essentially consists of a rectangular base plate 2, the two sides of which serve as a blasting agent running surface. The base plate 2 has a rib-shaped side edge 3 on each longitudinal edge. The cross section of the throwing blade 1 thus takes the form of a double T. The transitions from the base plate 2 to the side edges 3 are rounded, as required by the manufacturing processes of forging or casting. In pairs, mirror images at a distance from a central transverse axis AA, each side edge has recesses 4 on each side, which are essentially semicircular. The recesses 4 are provided both on the front and on the back of the throwing blade 1. The recesses 4 provided in the same transverse axis serve to fasten the throwing vane to a guide disc wheel. If, for example, the throwing vane is inserted into the guide disc wheel with the right end face in FIG. 1, the clamping elements engage in the recesses shown on the left in FIG. 1. The same applies if the throwing blade is pivoted through 180 ° about the longitudinal axis BB. If, however, the throwing vane is pivoted about the transverse axis AA 180 0, the clamping elements engage the - then situated at the location of the first recesses - symmetrically arranged recesses. The rib-shaped side edges 3 are provided on the end faces of the throwing blade 1 and in the transverse axis AA with reinforcing ribs 5 pointing outwards.

Die Wurfschaufel 1 ist sowohl bezogen auf ihre Querachse A-A als auch bezogen auf ihre Längsachse B-B vollständig symmetrisch ausgebildet. Sie kann in vier verschiedenen Einbaulagen eingesetzt werden. Das ergibt vier gleiche Wirkungsweisen.The throwing blade 1 is completely symmetrical both with respect to its transverse axis A-A and with respect to its longitudinal axis B-B. It can be used in four different installation positions. This results in four identical modes of action.

Handelt es sich bei der Wurfschaufel um eine lange Wurfschaufel, gilt folgendes: Bei einer mit der in Fig. 1 rechten Stirnseite nach innen in das Leitscheibenrad eingebrachten langen Wurfschaufel greifen die Spannelemente in die in Fig. 1 rechts dargestellten Ausnehmungen.If the throwing shovel is a long throwing shovel, the following applies: in the case of a long throwing shovel with the right end face in FIG. 1 inserted into the guide disc wheel, the tensioning elements engage in the recesses shown on the right in FIG. 1.
