Description

Die Erfindung betrifft eine Doppeltrommelfördermaschine mit einer angetriebenen Hauptwelle, mindestens einer auf der Hauptwelle drehbar gelagerten Lostrommel mit einer Bremse und einer Versteckvorrichtung zur lösbaren Verbindung von Lostrommel und Hauptwelle.The invention relates to a double drum winding machine with a driven main shaft, at least one loose drum rotatably mounted on the main shaft with a brake and a hiding device for the detachable connection of the loose drum and main shaft.

Bei einer Trommelfördermaschine wird als Seilträger eine Seiltrommel verwendet, auf der das Förderseil auf- oder abgewickelt wird. Man unterscheidet Einzeltrommelmaschinen und Doppeltrommelmaschinen. Doppeltrommelmaschinen können beispielsweise als Blairmaschinen oder Bobinen ausgeführt werden. Eine gattungsgemäße Doppeltrommelfördermaschine ist aus der EP 2 800 719 B1 bekannt. Die EP 0 062 029 A2 offenbart eine Doppeltrommelfördermaschine nach dem Oberbegriff des unabhängigen Anspruchs 1.In a drum hoisting machine, a rope drum is used as a rope carrier on which the hoisting rope is wound or unwound. A distinction is made between single drum machines and double drum machines. Double drum machines can, for example, be designed as Blair machines or reels. A generic double drum winder is from the EP 2 800 719 B1 known. the EP 0 062 029 A2 discloses a double drum winder according to the preamble of independent claim 1.

Doppeltrommelmaschinen gibt es sowohl mit einer Festtrommel und einer Lostrommel, als auch mit zwei Lostrommeln. Dabei werden die Lostrommeln über eine schaltbare Kupplung, die sogenannte Versteckvorrichtung, lösbar mit der Hauptwelle verbunden. Für jede Lostrommel der Trommelfördermaschine ist es erforderlich, dass zum Verstecken eine separate Bremse für die Lostrommel vorhanden ist.Double drum machines are available with a fixed drum and a lottery wheel, as well as with two lottery drums. The loose drums are detachably connected to the main shaft via a switchable coupling, the so-called hiding device. For each lottery wheel of the drum winder it is necessary that a separate brake is available for the lottery wheel for hiding.

Mit Hilfe der Versteckvorrichtung können beide Trommeln relativ zueinander in Umfangsrichtung versetzt werden. Hierzu wird die Lostrommel mit der ihr zugeordneten Bremse blockiert und von der weiteren Trommel, insbesondere einer Festtrommel, abgekuppelt. Dadurch dreht sich die Lostrommel beim Positionieren des zweiten Fördermittels mit Hilfe der weiteren Trommel nicht mit. Nachdem das zweite Fördermittel an der gewünschten Stelle positioniert ist, wird die Lostrommel wieder mit der Antriebswelle gekuppelt und die Bremse gelöst. Doppeltrommelfördermaschinen mit Versteckvorrichtungen ermöglichen daher die Förderung aus unterschiedlichen Tiefen, so dass beispielsweise ein Fördermittel unter Tage beladen, während gleichzeitig das andere über Tage entladen wird. Diese Funktion ist insbesondere beim Abteufen eines Schachtes wichtig, da sich hier die Teufe des Schachtes permanent ändert, um beispielsweise Abraum zu fördern oder während des Abteufens im Schacht Arbeiten zu verrichten. Die Wickelrichtung des Seils auf den Trommeln der Doppeltrommelfördermaschine ist gegenläufig, so dass bei gleicher Drehrichtung der Hauptwelle das Seil der einen Trommel aufgewickelt und das andere abgewickelt wird. Aufgrund der sowohl für das Fest- als auch das Loslager der Lostrommel verwendeten Gleitlager sind die Fahrgeschwindigkeiten des Fördermittels auf 1 m/s beschränkt. Insbesondere beim Abteufen tiefer Schächte besteht jedoch ein Bedürfnis nach höheren Fahrgeschwindigkeiten.With the aid of the hiding device, both drums can be offset relative to one another in the circumferential direction. For this purpose, the loose drum is blocked with the brake assigned to it and decoupled from the further drum, in particular a fixed drum. As a result, the lottery wheel does not rotate when the second conveyor is positioned with the aid of the further drum. After the second conveyor is positioned at the desired location, the The lottery wheel is coupled to the drive shaft again and the brake is released. Double drum conveying machines with hiding devices therefore enable conveyance from different depths, so that, for example, one conveyance is loaded underground while the other is unloaded above ground at the same time. This function is particularly important when sinking a shaft, since the depth of the shaft changes permanently here, for example in order to convey overburden or to carry out work in the shaft while it is being sunk. The winding direction of the rope on the drums of the double drum winder is opposite, so that with the same direction of rotation of the main shaft, the rope of one drum is wound and the other is unwound. Due to the plain bearings used for both the fixed and the loose bearings of the lottery wheel, the travel speeds of the conveyor are limited to 1 m / s. However, there is a need for higher travel speeds, particularly when sinking deep shafts.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Doppeltrommelfördermaschine zu schaffen, die höhere Fahrgeschwindigkeiten erlaubt.Based on this prior art, the invention is based on the object of creating a double drum hoisting machine that allows higher travel speeds.

Die Erfindung beruht auf dem Gedanken, die Gleitlager der Lostrommel durch Wälzlager zu ersetzen und zugleich zwischen den beiden Wälzlagern der Lostrommel ein Ersatzwälzlager die Welle umgebend zu haltern.The invention is based on the idea of replacing the sliding bearings of the lottery wheel with roller bearings and, at the same time, of holding a replacement roller bearing around the shaft between the two roller bearings of the lottery wheel.

Eine Reduktion der Reibung durch Einsatz der Wälzlager ermöglicht höhere Fahrgeschwindigkeiten von mehr als 6 m/s, wobei das erfindungsgemäß gehalterte Ersatzwälzlager den ansonsten sehr zeitaufwendigen, von Zeit zu Zeit erforderlichen Austausch der Wälzlager erheblich vereinfacht und dadurch unnötig lange Betriebsunterbrechungen vermeidet.A reduction in friction through the use of the roller bearings enables higher travel speeds of more than 6 m / s, with the replacement roller bearing held according to the invention being the otherwise very time-consuming one from time to time The necessary replacement of the rolling bearings is considerably simplified, thereby avoiding unnecessarily long interruptions in operation.

Bei den Wälzlagern handelt es sich vorzugsweise um Rollenlager, wobei ein Lager der Lostrommel als Festlager und das andere Lager als Loslager ausgeführt sind. Die Wälzlager verfügen über einen Außen- und Innenring, zwischen denen die Wälzköper geführt sind. Bei dem Festlager umfassen der Innen-und Außenring die Wälzkörper formschlüssig, sodass deren axiale Verschiebung in Richtung der Lagerachse ausgeschlossen ist. Bei dem Loslager umfasst lediglich der Außenring die Wälzkörper formschlüssig, während der Innenring eine Verschiebung der Wälzkörper gegenüber dem Innenring in Richtung der Lagerachse erlaubt.The roller bearings are preferably roller bearings, one bearing of the loose drum being designed as a fixed bearing and the other bearing as a floating bearing. The rolling bearings have an outer and inner ring, between which the rolling elements are guided. In the case of the fixed bearing, the inner and outer rings enclose the rolling elements in a form-fitting manner, so that their axial displacement in the direction of the bearing axis is excluded. In the case of the floating bearing, only the outer ring encompasses the rolling elements in a form-fitting manner, while the inner ring allows the rolling elements to be displaced relative to the inner ring in the direction of the bearing axis.

Eine vorteilhafte Ausgestaltung der Erfindung sieht zur lösbaren Halterung des Ersatzwälzlagers vor, dass an der Lostrommel mindestens eine Halterung für das mindestens eine Ersatzwälzalger befestigt ist und jede Halterung mehrere lösbar miteinander verbundene Teile aufweist, die derart eingerichet sind, dass durch das Lösen und Entfernen einzelner Teile jeder Halterung das mindestens eine Ersatzwälzlager aus der Halterung freikommt und in Achsrichtung der Hauptwelle bewegbar ist.An advantageous embodiment of the invention provides for the detachable mounting of the replacement roller bearing that at least one bracket for the at least one replacement roller bearing is attached to the loose drum and each bracket has several detachably interconnected parts, which are set up in such a way that by loosening and removing individual parts each bracket that at least one replacement roller bearing comes free from the bracket and is movable in the axial direction of the main shaft.

Jede Halterung ist vorzugsweise an den Querschnitt des Lagerrings des Ersatzwälzlagers angepasst und umgreift das Ersatzwälzlager allseitig. Beispielsweise durch Entfernen der beiden Seitenteile sowie des Unterteils jeder Halterung kommt das mindestens eine Ersatzwälzlager frei und kann anschließend die Hauptwelle umgebend in Achsrichtung verschoben und gegen eines der beiden Wälzlager der Lostrommel ausgetauscht werden.Each holder is preferably adapted to the cross section of the bearing ring of the replacement roller bearing and encompasses the replacement roller bearing on all sides. For example, by removing the two side parts and the lower part of each bracket, the at least one replacement roller bearing is released and can then be moved around the main shaft in the axial direction and against one of the two roller bearings Lottery wheel can be exchanged.

Die Halterung jedes Ersatzwälzlagers kann vor Verschmutzung geschützt in einem ringförmigen, die Hauptwelle umgebenden, mehrteiligen Kanal oder offen in dem Raum zwischen den Seitenwangen der Lostrommel mittels mehrerer den Querschnitt des Ersatzwälzlagers umfassender, mehrteiliger Halterungen erfolgen.Each replacement roller bearing can be secured against contamination in an annular, multi-part channel surrounding the main shaft or openly in the space between the side walls of the lottery wheel by means of several multi-part brackets encompassing the cross-section of the replacement roller bearing.

Die als ringförmiger Kanal ausgebildete Halterung ist vorzugsweise an mehreren der Schottbleche befestigt, die sich zwischen den Seitenwangen der Lostrommel erstrecken.The holder, designed as an annular channel, is preferably attached to several of the bulkhead plates which extend between the side walls of the lottery wheel.

Kommen mehrere Halterungen zum Einsatz, ist jeweils eine Halterung an dem unteren Rand eines der Schottbleche befestigt, der im Abstand zu der Mantelfläche der Hauptwelle verläuft.If several brackets are used, one bracket is attached to the lower edge of one of the bulkhead plates, which runs at a distance from the outer surface of the main shaft.

Um die Wälzlager problemlos ausbauen und ein Ersatzwälzlager einbauen zu können, sind an der Hauptwelle zwei Lagerflansche angeordnet, wobei an jedem Lagerflansch ein erster, mehrteiliger Klemmring zur formschlüssigen Aufnahme des Innenrings eines der beiden Wälzlager lösbar angeordnet ist und an jeder Seitenwange der Trommel ein zweiter, mehrteiliger Klemmring zur formschlüssigen Aufnahme des Außenrings eines der beiden Wälzlager lösbar angeordnet ist. Die Klemmringe können in Umfangsrichtung längs und/ oder quer zur Umfangsrichtung geteilt sein. Die Befestigung der Klemmringe an dem Lagerflansch bzw. der Seitenwange erfolgt vorzugsweise über Schraubverbindungen.In order to be able to remove the rolling bearings without any problems and to be able to install a replacement rolling bearing, two bearing flanges are arranged on the main shaft, with a first, multi-part clamping ring for the form-fitting reception of the inner ring of one of the two rolling bearings being arranged releasably on each bearing flange and a second, multi-part clamping ring for positively receiving the outer ring of one of the two roller bearings is detachably arranged. The clamping rings can be divided in the circumferential direction longitudinally and / or transversely to the circumferential direction. The clamping rings are preferably fastened to the bearing flange or the side cheek by means of screw connections.

Sofern ein Wälzlager der Lostrommel als Festlager und das andere Wälzlager als Loslager ausgeführt ist und zwei Ersatzwälzlager vorgehalten werden, ist benachbart zu dem Festlager ein als Festlager ausgebildetes erstes Ersatzwälzlager und benachbart zu dem Loslager ein als Loslager ausgebildetes zweites Ersatzwälzlager die Hauptwelle umgebend lösbar gehaltert.If one roller bearing of the loose drum is designed as a fixed bearing and the other roller bearing is designed as a floating bearing and two replacement roller bearings are provided, a first replacement roller bearing designed as a fixed bearing and adjacent to the floating bearing a second replacement roller bearing designed as a floating bearing are detachably supported surrounding the main shaft.

Sofern ein Wälzlager der Lostrommel als Festlager und das andere Wälzlager als Loslager ausgeführt ist und lediglich ein Ersatzwälzlager zwischen den beiden Wälzlagern vorgehalten wird, weist das Ersatzwälzlager ringförmige Adapterelemente zur wahlweisen Ausbildung des Ersatzwälzlagers als Festlager oder Loslager auf.If one roller bearing of the loose drum is designed as a fixed bearing and the other roller bearing is designed as a floating bearing and only a replacement roller bearing is kept between the two roller bearings, the replacement roller bearing has annular adapter elements for the optional design of the replacement roller bearing as a fixed bearing or floating bearing.

Die auf beiden Seiten des Innenrings angeordneten ringförmigen Adapterelemente zur Ausbildung eines Loslagers weisen dieselbe Stärke wie der Innenring auf, so dass der Rollenkörper des Ersatzwälzlagers gegenüber dem Innenring in Achsrichtung des Ersatzwälzlagers verschieblich ist.The annular adapter elements arranged on both sides of the inner ring to form a floating bearing have the same thickness as the inner ring, so that the roller body of the replacement roller bearing is displaceable relative to the inner ring in the axial direction of the replacement roller bearing.

Die auf beiden Seiten des Innenrings angeordneten ringförmigen Adapterelemente zur Ausbildung eines Festlagers weisen eine größere Stärke als der Innenring auf, so dass der Rollenkörper des Ersatzwälzlagers gegenüber dem Innenring in Achsrichtung des Ersatzwälzlagers nicht verschieblich ist. Die Adapterelemente zur Ausbildung des Festlagers führen daher den Rollenkörper in Achsrichtung des Lagers auch am Innenring formschlüssig.The annular adapter elements arranged on both sides of the inner ring to form a fixed bearing have a greater thickness than the inner ring, so that the roller body of the replacement roller bearing cannot be displaced relative to the inner ring in the axial direction of the replacement roller bearing. The adapter elements for forming the fixed bearing therefore guide the roller body in the axial direction of the bearing in a form-fitting manner on the inner ring as well.

Jede Lostrommel besteht aus zwei Hälften, die entlang einer Trennfuge jeder Seitenwange der Lostrommel lösbar miteinander verbunden sind. Die lösbare Verbindung erfolgt beispielsweise mittels Verbindungsflanschen, die entlang der Trennfuge an beiden Hälften angeordnet sind. Um die Demontage eines Wälzlagers und den Einbau eines Ersatzwälzlagers zu erleichtern, sind in einer Ausgestaltung der Erfindung auf beiden Seiten der Trennfuge Abdrückpratzen angeordnet. Nach dem Lösen der Schrauben der Verbindungsflansche können die Hälften der Lostrommel mittels einer zwischen den Abdrückpratzen wirkenden Spannvorrichtung geringfügig auseinandergedrückt werden. Die Abdrückpratzen sind beispielsweise als Brennteile an den Seitenwangen der Lostrommel angeordnet.Each lottery wheel consists of two halves which are detachably connected to one another along a parting line of each side wall of the lottery wheel. The detachable connection is made, for example, by means of connecting flanges which are arranged along the parting line on both halves. In order to facilitate the dismantling of a roller bearing and the installation of a replacement roller bearing, in one embodiment of the invention, forcing claws are arranged on both sides of the parting line. After loosening the screws of the connecting flanges, the halves of the loose drum can be pushed apart slightly by means of a clamping device acting between the push-off claws. The push-off claws are arranged, for example, as flame-cut parts on the side cheeks of the lottery wheel.

Figur 1 zeigt eine Doppeltrommelfördermaschine 1 mit einer auf einer Hauptwelle 2 angeordneten Festtrommel 3 und einer Lostrommel 4. Die Hauptwelle 2 wird von einem Antriebsmotor 5 angetrieben. Figure 1 shows a double drum winder 1 with a fixed drum 3 arranged on a main shaft 2 and a loose drum 4. The main shaft 2 is driven by a drive motor 5.

Sowohl die Festtrommel 3 als auch die Lostrommel 4 weisen jeweils eine Scheibenbremse 6,7 auf. Die Lostrommel 4 ist über eine Versteckvorrichtung 8 lösbar mit der Hauptwelle 2 verbunden.Both the fixed drum 3 and the loose drum 4 each have a disk brake 6, 7. The lottery wheel 4 is detachably connected to the main shaft 2 via a hiding device 8.

Die Hauptwelle 2 ist endseitig und zwischen dem Antriebsmotor 5 und der Festtrommel 3 in Gleitlagern 9,10 gelagert, wobei das Gleitlager 9 als Festlager und das Gleitlager 10 als Loslager ausgeführt ist.The main shaft 2 is supported at the end and between the drive motor 5 and the fixed drum 3 in sliding bearings 9, 10, the sliding bearing 9 being designed as a fixed bearing and the sliding bearing 10 as a floating bearing.

Aus Figur 2 ist erkennbar, dass die Festtrommel 3 über Klemmringe 11 drehfest mit der Hauptwelle 2 verbunden ist. Die Klemmringe sind mit den Seitenwangen der Festtrommel 3 verschraubt. Zwischen den Seitenwangen der Festtrommel 3 erstrecken sich Schottbleche 12.the end Figure 2 it can be seen that the fixed drum 3 is non-rotatably connected to the main shaft 2 via clamping rings 11. The clamping rings are screwed to the side walls of the fixed drum 3. Partition plates 12 extend between the side walls of the fixed drum 3.

Die Lostrommel 4 ist mit zwei Wälzlagern 13,14 auf der Hauptwelle 2 (Detail W in Figur 2) drehbar gelagert, wobei das Wälzlager 13 als Loslager und das Wälzlager 14 als Festlager ausgeführt ist. Zwischen den beiden Wälzlagern 13,14 der Lostrommel 4 ist ein Ersatzwälzlager 15 die Hauptwelle 2 umgebend lösbar gehaltert. Bei den beiden Wälzlagern 13,14 und dem Ersatzwälzlager 15 handelt es sich um Rollenlager. Die Rollenlager verfügen über einen Außen- und Innenring, zwischen denen die Wälzköper geführt sind. Bei dem Wälzlager 14 umfassen der Innen- und Außenring die Wälzkörper formschlüssig, sodass eine axiale Verschiebung der Wälzkörper in Richtung der Lagerachse ausgeschlossen ist. Bei dem Wälzlager 13 umfasst lediglich der Außenring die Wälzkörper formschlüssig, während der Innenring eine Verschiebung der Wälzkörper gegenüber dem Innenring in Richtung der Lagerachse erlaubt.The lottery wheel 4 is mounted on the main shaft 2 with two roller bearings 13, 14 (detail W in Figure 2 ) rotatably mounted, the roller bearing 13 being designed as a floating bearing and the roller bearing 14 as a fixed bearing. Between the two roller bearings 13, 14 of the loose drum 4, a replacement roller bearing 15 is detachably supported, surrounding the main shaft 2. The two roller bearings 13, 14 and the replacement roller bearing 15 are roller bearings. The roller bearings have an outer and inner ring, between which the rolling elements are guided. In the case of the roller bearing 14, the inner and outer rings encompass the roller bodies in a form-fitting manner, so that an axial displacement of the Rolling bodies in the direction of the bearing axis is excluded. In the case of the roller bearing 13, only the outer ring encompasses the roller bodies in a form-fitting manner, while the inner ring allows the roller bodies to be displaced relative to the inner ring in the direction of the bearing axis.

Wie insbesondere aus Figur 2 erkennbar erstrecken sich zwischen parallelen Seitenwangen 16.1, 16.2 der Lostrommel 4 Schottbleche 17. Am unteren Rand jedes Schottblechs 17 ist jeweils eine Halterung 18 für das Ersatzwälzlager 15 befestigt.Like in particular from Figure 2 It can be seen that partition plates 17 extend between parallel side walls 16.1, 16.2 of the loose drum 4. A holder 18 for the replacement roller bearing 15 is attached to the lower edge of each partition plate 17.

Jede Halterung 18 besteht aus einem parallel zur Drehachse der Hauptwelle 2 verlaufenden Steg 18.1, der an dem Schottblech 17 befestigt ist. An dem Steg 18.1 sind zwei parallele Seitenteile 18.2 sowie ein Unterteil 18.3 lösbar befestigt. Die derart an den Querschnitt des Ersatzwälzlagers 15 angepasste Halterung umgreift das Ersatzwälzlager allseitig.Each holder 18 consists of a web 18.1 which runs parallel to the axis of rotation of the main shaft 2 and is fastened to the bulkhead plate 17. Two parallel side parts 18.2 and a lower part 18.3 are detachably attached to the web 18.1. The holder adapted in this way to the cross section of the replacement roller bearing 15 encompasses the replacement roller bearing on all sides.

Durch Entfernen der beiden Seitenteile 18.2 sowie des Unterteils 18.3 jeder Halterung 18 kommt das Ersatzwälzlager 15 aus der Halterung 18 frei, wie in Figuren 4 B) und C) dargestellt, und kann anschließend die Hauptwelle 2 umgebend in Achsrichtung bewegt und gegen eines der beiden Wälzlager 13, 14 der Lostrommel 4 ausgetauscht werden.By removing the two side parts 18.2 and the lower part 18.3 of each holder 18, the replacement roller bearing 15 is released from the holder 18, as in FIG Figures 4 B) and C) shown, and the main shaft 2 can then be moved around in the axial direction and exchanged for one of the two roller bearings 13, 14 of the loose drum 4.

Das Ersatzwälzlager 15 weist zu diesem Zweck vier ringförmige Adapterelemente 19, 20 zur wahlweisen Ausbildung des Ersatzwälzlagers 15 als Festlager oder Loslager auf.For this purpose, the replacement roller bearing 15 has four ring-shaped adapter elements 19, 20 for the optional formation of the replacement roller bearing 15 as a fixed bearing or a floating bearing.

Die auf beiden Seiten des Innenrings des Ersatzwälzlagers 15 angeordneten ringförmigen Adapterelemente 19 zur Ausbildung des Ersatzwälzlagers als Loslager weisen dieselbe Stärke wie der Innenring auf, so dass die Wälzkörper 21 des Ersatzwälzlagers 15 gegenüber dem Innenring in Achsrichtung des Ersatzwälzlagers 15 verschieblich sind. Die Oberfläche der ringförmigen Adapterelemente 19 und des Innenrings bilden eine einheitliche Lauffläche für die Wälzkörper 21 des Ersatzwälzlagers 15 (Figur 4B).The annular adapter elements 19 arranged on both sides of the inner ring of the replacement roller bearing 15 for forming the replacement roller bearing as a floating bearing have the same thickness as the inner ring, so that the rolling elements 21 of the replacement roller bearing 15 can be displaced relative to the inner ring in the axial direction of the replacement roller bearing 15. The surface of the annular adapter elements 19 and the inner ring form a uniform running surface for the rolling elements 21 of the replacement rolling bearing 15 ( Figure 4B ).

Die auf beiden Seiten des Innenrings des Ersatzwälzlagers 15 angeordneten ringförmigen Adapterelemente 20 zur Ausbildung eines Festlagers weisen eine größere Stärke als der Innenring auf, so dass die Wälzkörper 21 des Ersatzwälzlagers 15 gegenüber dem Innenring in Achsrichtung des Ersatzwälzlagers nicht verschieblich sind. Die Adapterelemente 20 zur Ausbildung des Festlagers führen daher die Wälzkörper 21 in Achsrichtung des Lagers auch am Innenring formschlüssig. Die Oberfläche des Innenrings bildet die Lauffläche für die Rollenkörper 21 des Ersatzwälzlagers 15 (Figur 4C).The annular adapter elements 20 arranged on both sides of the inner ring of the replacement roller bearing 15 to form a fixed bearing have a greater thickness than the inner ring, so that the roller bodies 21 of the replacement roller bearing 15 cannot be displaced relative to the inner ring in the axial direction of the replacement roller bearing. The adapter elements 20 for forming the fixed bearing therefore guide the rolling elements 21 in the axial direction of the bearing in a form-fitting manner on the inner ring as well. The surface of the inner ring forms the running surface for the roller bodies 21 of the replacement roller bearing 15 ( Figure 4C ).

An der Hauptwelle 2 sind im Abstand der beiden Seitenwangen 16.1, 16.2 der Lostrommel 4 zwei Lagerflansche 22, 23 angeformt. An dem Lagerflansch 22 für das Loslager ist ein erster, mehrteiliger Klemmring 24.1 zur formschlüssigen Aufnahme des Innenrings des Wälzlagers 13 (Loslager) angeschraubt. An dem Lagerflansch 23 für das Festlager ist ebenfalls ein erster, mehrteiliger Klemmring 24.2 zur formschlüssigen Aufnahme des Innenrings des Wälzlagers 14 (Festlager) angeschraubt. An der Seitenwange 16.1 der Lostrommel 4 ist ein zweiter, mehrteiliger Klemmring 25.1 zur formschlüssigen Aufnahme des Außenrings des Wälzlagers 13 (Loslager) angeschraubt. An der Seitenwange 16.2 der Lostrommel 4 ist ein zweiter, mehrteiliger Klemmring 25.2 zur formschlüssigen Aufnahme des Außenrings des Wälzlagers 14 (Festlager) angeschraubt.Two bearing flanges 22, 23 are formed on the main shaft 2 at a distance between the two side walls 16.1, 16.2 of the loose drum 4. A first, multi-part clamping ring 24.1 is screwed to the bearing flange 22 for the floating bearing for the form-fitting reception of the inner ring of the roller bearing 13 (floating bearing). A first, multi-part clamping ring 24.2 for the form-fitting reception of the inner ring of the roller bearing 14 (fixed bearing) is also screwed onto the bearing flange 23 for the fixed bearing. On the side wall 16.1 of the Loose drum 4 is screwed on a second, multi-part clamping ring 25.1 for the form-fitting reception of the outer ring of the roller bearing 13 (loose bearing). A second, multi-part clamping ring 25.2 for positively receiving the outer ring of the roller bearing 14 (fixed bearing) is screwed onto the side cheek 16.2 of the loose drum 4.

Die Lostrommel 4 besteht aus zwei Hälften 4.1, 4.2, die entlang einer Trennfuge 26 jeder Seitenwange 16.1, 16.2 der Lostrommel lösbar miteinander verbunden sind. Die lösbare Verbindung erfolgt mittels Verbindungsflanschen 27 (vgl. insbesondere Figur 1), die entlang der Trennfuge 26 an beiden Hälften 4.1, 4.2) angeordnet sind und durch Schrauben miteinander verbunden werden. Um die Demontage eines Wälzlagers 13,14 und den Einbau eines Ersatzwälzlagers 15 zu erleichtern, sind auf beiden Seiten der Trennfuge 26 Abdrückpratzen 28 angeordnet. Nach dem Lösen der Schrauben der Verbindungsflansche können die Hälften 4.1, 4.2 der Lostrommel mittels einer zwischen den Abdrückpratzen wirkenden Spannvorrichtung geringfügig auseinandergedrückt werden.The lottery wheel 4 consists of two halves 4.1, 4.2, which are detachably connected to one another along a parting line 26 of each side wall 16.1, 16.2 of the lottery wheel. The detachable connection is made by means of connecting flanges 27 (cf. in particular Figure 1 ), which are arranged along the parting line 26 on both halves 4.1, 4.2) and are connected to one another by screws. In order to facilitate the dismantling of a roller bearing 13, 14 and the installation of a replacement roller bearing 15, forcing claws 28 are arranged on both sides of the parting line 26. After loosening the screws of the connecting flanges, the halves 4.1, 4.2 of the loose drum can be pushed apart slightly by means of a clamping device acting between the push-off claws.
