Description

Die Erfindung betrifft ein Laufradblock mit einem Gehäuse mit mindestens einer die Tragkraft aufnehmenden Anschlussfläche und mit Drehlager-Sitzflächen für Gleit- und/oder Wälzlager für die Lagerung eines Laufrads, wobei zur Demontage des Laufrads aus dem Gehäuse die Gleit- und/oder Wälzlager nach außen und das Laufrad zu einer etwa quer dazu gelegenen Seite hin ausbaubar sind.The invention relates to an impeller block having a housing with at least one supporting surface receiving the bearing surface and with pivot bearing seating surfaces for sliding and / or rolling bearings for the storage of an impeller, wherein for disassembly of the impeller from the housing, the sliding and / or rolling outwards and the impeller are expandable to an approximately transverse side towards it.

Es sind verschiedene Bauarten von Laufradblöcken bekannt, die konzeptionell den Austausch des Laufrads auf unterschiedlicher Weise vorsehen bzw. erlauben.Various types of impeller blocks are known which conceptually provide or permit replacement of the impeller.

Die aus der DE 31 34 750 A1 bekannten Laufradblöcke sind aus zwei zusammengeschweißten oder anderweitig verbundenen Hälften der Lagergehäuse gebildet und weisen eingepresste Drehlagersitzflächen für Lager auf, in denen die Nabe des Laufrades abgestützt ist. Hierbei schließen sich an die Drehlagersitzflächen zur Nabe gerichtete Anschlagschultern für die Lager an und das Laufrad reicht mit seiner Nabe bis über die Lager und ist darüber direkt an dem Gehäuse abgestützt, und die Nabe weist ferner an ihren beidseitigen Außenringen Ringnuten für an den Stirnseiten der Lager anliegende Sprengringe und einen Aufnahmedurchbruch mit einer Innenverzahnung für eine Außenverzahnung einer Antriebswelle auf.The from the DE 31 34 750 A1 known impeller blocks are formed from two welded together or otherwise connected halves of the bearing housing and have pressed-Drehlagersitzflächen for bearing in which the hub of the impeller is supported. This is followed by the hub bearing seating surfaces directed to the hub stop shoulders for the bearing and the impeller extends with its hub up over the bearings and is supported directly on the housing, and the hub also has on its two-sided outer rings annular grooves for at the ends of the camp adjacent snap rings and a receiving opening with an internal toothing for external toothing of a drive shaft.

Diese Bauweise hat sich seit Jahren in der Praxis bewährt. Es besteht jedoch weiterhin das Erfordernis der Kostenminimierung sowie der Funktionsverbesserung. Ein Austausch des Laufrades der DE 31 34 750 A1 ist nur durch Austausch des Laufradblocks in seiner Gesamtheit möglich. Nach Auswechseln muss der gesamte Laufradblock wieder an dem Tragwerk - genau wie bei der Erstmontage - mittels Schrauben befestigt werden. Dabei ist der Laufradblock in seiner Lage relativ zum Tragwerk mit den anderen Laufrädern auszurichten, damit die Drehachse des Laufrades rechtwinklig zur Laufradbahn, auf der das Laufrad abwälzt, verläuft. Wenn der Ausrichtvorgang nicht durchgeführt wird, besteht die Gefahr, dass die Laufräder durch Schräglauf auf der Laufradbahn schroten (abreiben) und dadurch schneller verschleißen. Weiterhin besteht im Anwendungsfall eines Brückenkranes die Gefahr, dass das Laufverhalten des Brückenkranes empfindlich durch Schräglauf, Anecken und Spurkranzverschleiß gestört wird. Zusätzlich treten mit wachsendem Schräglaufwinkel Seitenkräfte auf, die das Tragwerk u. dgl. über die Betriebsbeanspruchung hinaus belasten. Diese Problematik wird ausführlich in der DIN 15018 beschrieben.This design has been proven in practice for years. However, there is still the requirement of cost minimization and functional improvement. An exchange of the impeller of DE 31 34 750 A1 is only possible by replacing the impeller block in its entirety. After replacement, the entire impeller block must be re-attached to the structure - as in the initial installation - by means of screws. In this case, the impeller block is to align in its position relative to the supporting structure with the other wheels, so that the axis of rotation of the impeller perpendicular to the impeller track on which the impeller rolls, runs. If the alignment procedure is not carried out, there is a risk that the impellers will be scraped (skewed) due to skewing on the impeller path and thus wear out more quickly. Furthermore, there is the danger in the application of a bridge crane that the running behavior of the bridge crane is sensitive disturbed by skew, ticks and wheel flange wear. In addition, join As the slip angle increases, there are lateral forces on the structure and the like. Like. Load beyond the operating stress addition. This problem is described in detail in DIN 15018.

Eine andere Konstruktion eines Laufradblocks ist in der DE 195 40 220 C1 offenbart. Hierbei weist der Laufradblock ein Gehäuse auf, in dem Drehlager-Sitzflächen für Gleit- und/oder Wälzlager für die Aufnahme eines zumindest nach einer Seite herausragenden Laufrades vorgesehen sind, wobei das Gehäuse zum Ausbau des Laufrades nach einer Seite hin durch Abnahme eines lösbaren Deckels zerlegbar ist, so dass das Gehäuse zum Laufradwechsel nicht mehr vom Tragwerk gelöst werden muss. Jedoch muss bei diesem Laufrad zur Montage bzw. Demontage eine Vielzahl von Teilen gelöst bzw. befestigt werden.Another construction of a wheel block is in the DE 195 40 220 C1 disclosed. Here, the impeller block has a housing, are provided in the pivot bearing seats for sliding and / or rolling bearing for receiving a projecting at least one side impeller, the housing for removing the impeller to one side by taking a detachable lid can be dismantled is, so that the housing for impeller replacement must not be solved by the structure. However, in this impeller for mounting or dismounting a variety of parts must be solved or fixed.

Eine weitere Konstruktion eines Laufradblocks ist aus der DE 195 40 217 C1 bekannt. Sie sieht die Verwendung von so genannten Ringkörpern vor, die zur Aufnahme der Lager in den Gehäusewandungen des Laufradblocks dienen. Sie werden dazu nach Einführen des Laufrads mit seiner Nabe von Außen auf die Nabe und deren Lager aufgeschoben und im Gehäuse festgelegt. Auch bei diesen Laufrädern ist die Montage bzw. Demontage mit dem Lösen bzw. Befestigen einer Vielzahl von Teilen verbunden. Insbesondere müssen die Ringkörper entfernt und ausgerichtet werden.Another construction of a wheel block is from the DE 195 40 217 C1 known. It provides for the use of so-called ring bodies, which serve to accommodate the bearings in the housing walls of the impeller block. They are pushed to insert the impeller with its hub from the outside to the hub and its bearings and fixed in the housing. Also in these wheels, the assembly or disassembly is associated with the loosening or securing a plurality of parts. In particular, the ring body must be removed and aligned.

Der Montage- / Demontageaufwand ist zwar bei fliegend gelagerten Laufrädern geringer, jedoch wird dies mit einem hohen konstruktiven Aufwand für die Lagerung erkauft, ohne die die nötige Steifigkeit nicht erreichbar wäre.Although the assembly / disassembly effort is lower in the case of cantilevered wheels, this is achieved with a high design effort for storage, without which the necessary rigidity would not be achievable.

Aus der DE 195 40 217 C1 ist zusätzlich ein Laufradblock in einer weiteren Ausführungsform bekannt, die sich im Wesentlichen dadurch auszeichnet, dass die Lager für das Laufrad direkt in Sitzflächen eingesetzt werden, die in Aussparungen der Gehäusewandung vorgesehen sind. Zur Demontage des Laufrades werden die Lager nach Lösen eines Sicherungsringes seitlich aus den Aussparungen abgezogen. Um nun das Laufrad aus dem Gehäuse entfernen zu können, muss die umlaufende Sitzfläche für das Lager geöffnet werden. Hierfür wird eine seitlich das Gehäuse verschließende Platte entfernt. An dieser Platte sind zusätzlich in das Gehäuse hinein ragende Stege angeordnet, die im montierten Zustand der Platte einen Teil der Sitzfläche für die Lager bilden. Diese Stege werden mit der Platte aus dem Gehäuse entfernt. Nun kann das Laufrad mit seinen beidseitig auskragenden Nabenstummeln seitlich aus dem Gehäuse entnommen werden. Die Nabenstummel passieren hierbei den zuvor von den Stegen verschlossenen Raum.From the DE 195 40 217 C1 In addition, an impeller block is known in a further embodiment, which is characterized essentially by the fact that the bearing for the impeller are used directly in seats, which are provided in recesses of the housing. To disassemble the impeller, the bearings are removed after loosening a retaining ring laterally from the recesses. In order to be able to remove the impeller from the housing, the circumferential seating surface for the bearing must be opened. For this purpose, a laterally closing the housing plate is removed. At this plate in addition into the housing projecting webs are arranged, which form a part of the seat surface for the bearings in the mounted state of the plate. These webs are removed with the plate from the housing. Now, the impeller with its projecting hub stubs on both sides laterally out of the housing be removed. The hub stubs in this case pass the previously closed by the webs space.

Ferner ist aus der DE M 19790 XI/35b eine leicht lösbar befestigte Lagerung von Laufrädern für Krane bekannt. Das Laufrad weist beidseitig austretende Wellenstummel auf, auf denen jeweils ein gekapseltes Lager angeordnet ist. Die Lager sind auf dem Wellenstummel zwischen Anschlägen begrenzt verschiebbar. Zur Befestigung des Laufrades zwischen zwei parallelen und voneinander beabstandeten Trägerblechen des Krans werden auf den Außenseiten der Trägerbleche jeweils zwei kräftige flache Haltestücke angeordnet, die im eingebauten Zustand des Laufrades konzentrisch zu den Wellenstummeln des Laufrades ausgerichtete scheibenförmige Vertiefungen aufweisen. Zusätzlich sind in den Trägerblechen und den Halteblechen nach unten weisende Schlitze angeordnet, deren Breite leicht größer als der Durchmesser der Wellenstummel ist. Zur Montage des Laufrades können dann bei nach außen verschobenen gekapselten Lagern die Wellenstummel von unten in die Schlitze eingeführt werden. Anschließend werden die gekapselten Lager formschlüssig auf den Wellenstumpfen in Richtung der jeweiligen Haltebleche geschoben, bis diese in die scheibenförmige Vertiefung formschlüssig eingreifen. Die gekapselten Lager werden dann mit den Halteblechen und Trägerblechen verschraubt.Furthermore, from the DE M 19790 XI / 35b an easily releasably mounted storage of wheels for cranes known. The impeller has on both sides exiting stub shafts, on each of which an encapsulated bearing is arranged. The bearings are limitedly displaceable on the stub shaft between stops. For attachment of the impeller between two parallel and spaced support plates of the crane each two strong flat holding pieces are arranged on the outer sides of the support plates, which have concentric with the shaft stubs of the impeller aligned disc-shaped recesses in the installed state of the impeller. In addition, in the support plates and the holding plates downwardly facing slots are arranged, whose width is slightly larger than the diameter of the stub shaft. For assembly of the impeller can then be inserted from below into the slots with outwardly shifted encapsulated bearings the stub shaft. Subsequently, the encapsulated bearings are positively pushed onto the stub shaft in the direction of the respective retaining plates until they engage positively in the disc-shaped recess. The encapsulated bearings are then bolted to the retaining plates and carrier plates.

Außerdem ist aus der deutschen Offenlegungsschrift DE 28 18 170 A1 ein sogenannter Krankopfträger bekannt, der beispielsweise als Fahrwerksteil einer Kranlaufkatze eines Brückenkrans Verwendung findet. Gegenüber den zuvor beschriebenen Laufradblöcken nach dem Stand der Technik handelt es sich bei diesem Krankopfträgem nicht um einseitig offene quaderförmige Gehäuse, die geringfügig größere Abmessungen als die darin gelagerten Laufräder aufweisen, sondern um rohrförmige Träger mit einem rechteckigen Querschnitt, in deren jeweils gegenüberliegenden Enden jeweils ein Schienenlaufrad gelagert ist. Hierzu sind die Kopfträger neben den offenen Enden noch zusätzlich auf Länge des Laufrades auch an ihrer Unterseite geöffnet, damit das Laufrad nach unten aus dem Kopfträgern herausragen kann. Die Laufräder weisen jeweils eine Laufradwelle auf, die beidendig über nicht dargestellte Wälzlager in Lagerflanschen gelagert sind. Diese Lagerflansche umschließen das Wälzlager und auch die Laufradwelle in Umfangsrichtung gesehen jeweils vollständig. Zur Befestigung der Laufräder innerhalb der Enden der Krankopfträger sind in den jeweiligen Seitenwänden der Krankopfträger Bohrungen vorgesehen, an die sich jeweils in Horizontalrichtung und in Richtung des Endes des Kopfträgers ein Schlitz anschließt. Dieser Schlitz dient dazu, die Laufräder gemeinsam mit ihrer Laufradwelle in den Krankopfträger zu montieren. Hierfür werden die Laufräder mit ihren seitlich hervorragenden Laufradwellen von der Stirnseite des Endes eines Krankopfträgers in den Schlitz hineingeführt, bis diese die Bohrung in der Seitenwand des Kopfträgers erreichen. Dann werden die Wälzlager mit den Lagerflanschen von beiden Seiten jeweils auf die Laufradwellen der Laufräder aufgeschoben, bis die Lagerflansche an den Außenseiten der Seiten des Kopfträgers sowie in der Bohrung in der Seitenwand des Kopfträgers zur Anlage kommen. Üblicherweise werden dann die Lagerflansche mit den Seitenwänden der Kopfträger verschraubt und somit dort befestigt. Der Aus- und Einbau der Laufräder erfolgt somit zu bzw. von den stirnseitigen Enden der Kopfträger und die Laufräder ragen im eingebauten Zustand in Richtung der Schiene nach unten, d. h. im vorliegenden Fall um 90° versetzt zur Ein- und Ausbaurichtung, aus dem Krankopfträger hinaus.Moreover, from the German Offenlegungsschrift DE 28 18 170 A1 a so-called crane carrier known, for example, as a chassis part of a crane trolley of a bridge crane is used. Compared with the previously described impeller blocks according to the prior art, this Krankopfträgem not unilaterally open cuboidal housing having slightly larger dimensions than the wheels mounted therein, but to tubular support with a rectangular cross-section, in each of which opposite ends in each case Rail runner is mounted. For this purpose, the head support in addition to the open ends in addition to length of the impeller also open on its underside so that the impeller can protrude down from the headrests. The wheels each have an impeller shaft, which are mounted at both ends via bearings, not shown, in bearing flanges. These bearing flanges completely surround the rolling bearing and also the impeller shaft in the circumferential direction. For attachment of the wheels within the ends of the crane head carrier holes are provided in the respective side walls of the crane head, to which in each case in the horizontal direction and in the direction of the end of the head carrier is followed by a slot. This slot serves the wheels together with its impeller shaft to mount in the crane carrier. For this purpose, the wheels are guided with their laterally excellent impeller shafts from the front side of the end of a crane overhead carrier in the slot until they reach the hole in the side wall of the head carrier. Then the bearings are pushed with the bearing flanges from both sides in each case on the impeller shafts of the wheels until the bearing flanges come to rest on the outsides of the sides of the head carrier and in the bore in the side wall of the head carrier. Usually then the bearing flanges are bolted to the side walls of the head support and thus fixed there. The removal and installation of the wheels thus takes place to or from the front ends of the head support and the wheels protrude in the installed state in the direction of the rail down, ie offset in the present case by 90 ° to the installation and removal direction, from the crane overhead ,

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, bei einem Laufradblock die Montage bzw. Demontage oder Wechsel des Laufrads zu erleichtern.The present invention is therefore based on the object to facilitate the assembly or disassembly or replacement of the impeller in a wheel block.

Diese Aufgabe wird durch die in Anspruch 1 wiedergegebene Erfindung gelöst.This object is achieved by the reproduced in claim 1 invention.

Dadurch, dass die Drehlager-Sitzflächen derart ausgebildet sind, dass diese die Gleit- und/oder Wälzlager mehr als halbkreisförmig umschließen und in Bezug auf die Gleit- und/oder Wälzlager zur Seite eine Engstelle bildend offen sind, sowie dass das Laufrad im eingebauten Zustand zu dieser Seite aus dem Gehäuse herausragt, ist es möglich den Montageaufwand zu verringern. Ferner entfällt pro Lagerseite eine zusätzliche Passung, so dass eine höhere Genauigkeit der Laufradausrichtung und eine höhere Wiederholgenauigkeit beim Laufradwechsel erreicht werden. Als Folge treten geringere Schräglaufkräfte auf und damit einhergehend ein geringerer Verschleiß am Laufrad.Characterized in that the pivot bearing seats are designed such that they surround the sliding and / or rolling more than semicircular and forming a bottleneck to the side forming in relation to the sliding and / or rolling bearings, and that the impeller in the installed state To this side protrudes from the housing, it is possible to reduce the assembly costs. Furthermore, there is no need for an additional fit per bearing side, so that a higher accuracy of the wheel alignment and a higher repeat accuracy when changing the impeller are achieved. As a result, lower skew forces occur and, consequently, less wear on the impeller.

Durch die nicht vollständig umschlossenen Aussparungen bzw. Lagerstellen ist es möglich, das Laufrad inklusive Nabe in das Gehäuse einzuführen und anschließend durch Aufschieben der Lager zu sichern.Due to the not completely enclosed recesses or bearings, it is possible to introduce the impeller including the hub in the housing and then secure by sliding the bearings.

Dazu ist es von Vorteil, wenn die nicht vollständig umschlossenen Aussparungen eine Engstelle aufweisen, die geringfügig größere Ausmaße als der Durchmesser der Nabe des Laufrads aufweist. Auch können die Gleit- und/oder Wälzlager dabei kleiner als die nicht vollständig umschlossenen Aussparungen und größer als die Engstelle ausgeführt sein.For this purpose, it is advantageous if the not completely enclosed recesses have a constriction which has slightly larger dimensions than the diameter of the hub of the impeller. Also, the sliding and / or rolling bearings can be made smaller than the not completely enclosed recesses and larger than the bottleneck.

Entsprechend sind die Aussparungen zur Seite hin derart offen, dass das Laufrad nach seitlichem Entfernen der Gleit- und/oder Wälzlager zur Seite hin ausbaubar ist. Bei der Seite handelt es sich vorzugsweise um die nach unten gerichtete Seite.Accordingly, the recesses are open to the side so that the impeller after lateral removal of the sliding and / or roller bearings can be expanded to the side. The page is preferably the down side.

Die Aussparungen können dabei im Schnitt besehen etwa eine schlüsseloch-förmige Gestalt aufweisen.The recesses can be seen in section have about a keyhole-shaped shape.

Die Aussparungen des Laufradblocks weisen Vorteilhafterweise einen etwa kreisförmigen oberen Bereich zur Aufnahme der Gleit- und/oder Wälzlager und einen, insbesondere einen zur Seite offenen Winkel ausbildenden, unteren Bereich auf, der sich an dem oberen Bereich an der Engstelle anschließt. Dies erlaubt eine gute Festlegung der Lager und hohe Stabilität bzw. gute Aufnahme der Kräfte und trotzdem eine sichere und einfache Montage und Befestigung des Laufrads.The recesses of the impeller block advantageously have an approximately circular upper area for receiving the sliding and / or rolling bearings and a, in particular forming an angle open to the side, the lower area, which adjoins the upper area at the bottleneck. This allows a good determination of the bearings and high stability and good absorption of forces and still safe and easy installation and attachment of the wheel.

Der etwa kreisförmige obere Bereich der Aussparungen beschreibt dabei im Schnitt etwa einen Dreiviertelkreis.The approximately circular upper portion of the recesses describes about a three-quarter circle in section.

Die Anschlussfläche kann auf jeder Seite des Gehäuses vorgesehen sein, aus der das Laufrad nicht herausragt. Insbesondere handelt es sich um eine Kopfanschlussfläche, die auf der Oberseite des Gehäuses angeordnet ist.The pad may be provided on each side of the housing from which the impeller does not protrude. In particular, it is a head connection surface which is arranged on the upper side of the housing.

Weitere Merkmale, Einzelheiten und Vorteile der Erfindung werden anhand der nachfolgenden Beschreibung der Zeichnung erläutert. Es zeigt:

Die Flächen 3B, die Bohrungen zur Aufnahme von Verbindungsbolzen umgeben, dienen als Anlageflächen. Die Fläche 3C wird zur Befestigung von Rollenführungen und Puffern eingesetzt. Die Unterseite ist mit 3D bzw. 8 bezeichnet.The housing 2 also has longitudinal sides 2B and end faces 2C, which also have raised surfaces 3B and 3C. The surfaces 3B, which surround bores for receiving connecting bolts, serve as abutment surfaces. Surface 3C is used to fasten roller guides and buffers. The underside is labeled 3D or 8 respectively.

In dem Gehäuse 2 ist ein Laufrad 6 vorgesehen, welches sich mit seiner Nabe 7 um die Achse A dreht und nach unten zur Seite 8 hin teilweise aus dem Gehäuse 2 herausragt. Bei üblicher Einbaulage ist die Achse A horizontal ausgerichtet. Die Nabe 7 wird seitlich jeweils in Gleit- und/oder Wälzlager 5 gelagert, die in das Gehäuse 2 eingesetzt werden.In the housing 2, an impeller 6 is provided, which rotates with its hub 7 about the axis A and protrudes down to the side 8 partially out of the housing 2. In the usual installation position, the axis A is aligned horizontally. The hub 7 is mounted laterally in each case in sliding and / or roller bearings 5, which are inserted into the housing 2.

In den beiden Längsseiten 2B des Gehäuses sind Drehlager-Sitzflächen 4 vorgesehen, die direkt in der Gehäusewandung durch die Flächen der Aussparungen 9 gebildet sind. Sie weisen einen oberen, im Schnitt kreisförmigen Bereich 11 und einen unteren, einen zur Seite 8 bzw. Unterseite 3D hin offenen Winkel bildenden Bereich 12 auf. Die Aussparungen 9 sind also nicht vollständig von der Gehäusewandung umschlossen und weisen einen etwa schlüssellochförmigen Längsschnitt auf. Zwischen dem oberen, im Schnitt kreisförmigen Bereich 11 und dem unteren, einen zur Unterseite 8 hin offenen Winkel bildenden Bereich 12 besteht eine Übergangs- bzw. Engstelle 13, die ein Ausmaß aufweist, dass geringfügig größer als der Durchmesser der Nabe 7 ist. Die Nabe 7 ist also von unten her in die Aussparungen 9 bzw. deren oberen, im Schnitt kreisförmigen Bereiche 11 einführbar.In the two longitudinal sides 2B of the housing pivot bearing seats 4 are provided, which are formed directly in the housing by the surfaces of the recesses 9. They have an upper region 11 which is circular in section and a lower region 12 which forms an angle which is open towards side 8 or bottom side 3D. The recesses 9 are therefore not completely enclosed by the housing wall and have an approximately keyhole-shaped longitudinal section. Between the upper, sectionally circular region 11 and the lower, forming an opening 8 to the bottom side 8 forming an area or constriction 13, which has a degree that is slightly larger than the diameter of the hub 7. The hub 7 is thus inserted from below into the recesses 9 and their upper, in section circular regions 11.

In den oberen, im Schnitt kreisförmigen Bereich 11 werden Gleit- und/oder Wälzlager 5 eingepresst, die zur Lagerung der Enden der Nabe 7 dienen. Im montierten Zustand sind sowohl die Gleit- und/oder Wälzlager 5 und die im Schnitt kreisförmigen Bereiche 11, in die die Lager 5 eingepresst werden, konzentrisch zu der Drehachse A des Laufrads 6 ausgerichtet. Entsprechend sind die Durchmesser der Gleit- und/oder Wälzlager 5 kleiner als der Durchmesser der oberen, im Schnitt kreisförmigen Bereiche 11 und größer als die Breite der Engstelle 13. Somit "fallen" sie nicht aus dem Gehäuse heraus.In the upper, in section circular region 11 sliding and / or rolling bearings 5 are pressed, which serve to support the ends of the hub 7. In the assembled state, both the sliding and / or roller bearings 5 and the circular sections 11 in which the bearings 5 are pressed, concentrically aligned with the axis of rotation A of the impeller 6. Accordingly, the diameters of the sliding and / or rolling bearings 5 are smaller than the diameter of the upper, circular in section 11 and larger than the width of the constriction 13. Thus, they do not "fall out" of the housing.

Zur Montage wird also das Laufrad 6 mit seiner Nabe 7 zusammen von unten, d. h. von der Seite 8 her in das Gehäuse 2 eingeführt, wobei die Enden der Nabe 7 jeweils in die Aussparungen 9 hineinragen und letztendlich in die im Schnitt kreisförmigen Bereiche 11 eingeführt werden.For assembly so the impeller 6 with its hub 7 together from below, d. H. introduced from the side 8 in the housing 2, wherein the ends of the hub 7 each protrude into the recesses 9 and are finally introduced into the circular in section 11 areas.

Anschließend werden die Gleit- und/oder Wälzlager 5 mit ihrem Innenring 5B seitlich auf die Nabe 7 aufgeschoben und mit ihrem Außenring 5A in die Aussparungen 9 bzw. deren oberen, im Schnitt kreisförmigen Bereiche 11 eingebracht und dort in die Drehlager-Sitzflächen 4 eingepresst. Zum Schluss werden Sicherungsringe 10 auf die Enden der Nabe 7 aufgebracht, die zur Sicherung in entsprechend in den Enden der Nabe 7 vorgesehene Nuten 14 eingreifen.Subsequently, the sliding and / or rolling bearings 5 with their inner ring 5 B laterally pushed the hub 7 and inserted with its outer ring 5A in the recesses 9 and their upper, circular in section areas 11 and pressed there into the pivot bearing seats 4. Finally, locking rings 10 are applied to the ends of the hub 7, which engage for securing in accordance with provided in the ends of the hub 7 grooves 14.

Durch die Ausgestaltung des Laufradblocks 1 wird das Laufrad 2 mit seiner Nabe 7 zusammen direkt im Gehäuse 2 gelagert, ohne dass ein Einsatz von Ringkörpern notwendig ist. Damit wird zum einen die Montage erleichtert. Es entfallen pro Lagerseite zusätzliche Teile wie Passungen. Ferner wird durch die direkte Lagerung eine höhere Genauigkeit der Radausrichtung und auch eine höhere Wiederholungsgenauigkeit beim Radwechsel erlaubt. Somit treten geringere Schräglaufkräfte auf und entsprechend ein geringerer Verschleiß am Laufrad.Due to the design of the impeller block 1, the impeller 2 is mounted with its hub 7 together directly in the housing 2, without the use of ring bodies is necessary. This facilitates the assembly on the one hand. It accounts for each bearing side additional parts such as fits. Furthermore, a higher accuracy of the wheel alignment and a higher repetition accuracy when changing the wheel is allowed by the direct storage. Thus occur lower skew forces and accordingly a lower wear on the impeller.
