Abstract

The aim of the invention is to create a guide shoe bearing for rotary drums, e.g. tube mills, that can be easily constructed and economically manufactured while, nevertheless, ensuring that, during operation, it can take part in all angular movements of the rotary drum shell. To this end, the invention provides that a plate-shaped elastic body (13) is arranged between the guide shoe bearing element (11) and the associated bearing block (12), and the elastic body (13) is housed in a housing (14), which surrounds the same while being open toward the underside of the guide shoe. The housing (14) with the housed plate-shaped body (13) is closed from the top in a plunger-like manner by the guide shoe underside (15) so that the elastic body (13) functions like a ball joint for the radially supported guide shoe bearing element (11) for all angular motions of the rotary drum shell (10) occurring when the rotary drum is operating.

Description

Gleitschuhlagerung für Drehtrommeln wie z. B. für eine Sliding shoe storage for rotary drums such as B. for a
Rohrmühletube mill
B E S C H R E I B U N GDESCRIPTION
Die Erfindung betrifft eine Gleitschuhlagerung für Drehtrommeln wie z. B. für eine Rohrmühle, deren Drehrohr pro Lagerstation auf mehreren um den unteren Drehrohrumfang verteilten mit Drucköl beaufschlagten Gleitschuhlagerelementen gelagert ist, die jeweils kugel- gelenkig gegen einen Lagerbock radial abgestützt sind.The invention relates to a sliding shoe bearing for rotary drums such. B. for a tube mill, the rotary tube of which is supported per bearing station on several slide shoe bearing elements distributed around the lower rotary tube circumference and pressurized with oil, each of which is supported radially in a ball-and-socket manner against a bearing block.
Bekannt ist, große schwere Drehrohre wie z. B. Rohrmühlen auf mehreren um den unteren Drehrohrumfang verteilt angeordneten Gleitschuhlagerelementen zu lagern, wobei das Drehrohr auf Polstern von Drucköl lastet, das in den Schmierspalt zwischen den Gleitlagerschuhen und der radial abgestützten Drehtrommel-Lauffläche gedrückt wird. Dabei ist es z. B. aus der US-A-4,322,116 bekannt, die Unterseite der Gleitschuhlagerelemente mit sphärisch gewölbten bzw. ku- gelkalottenförmigen Flächen zu versehen, über welche sich das je- weilige Gleitschuhlagerelement am jeweiligen Lagerbock abstützt, dessen Oberseite ebenfalls mit entsprechend sphärisch gewölbten Flächen versehen ist. Aufgrund des kugelkalottenförmigen Sitzes sollen die Gleitschuhlagerelemente Änderungen des Neigungswinkels oder sonstige Winkeländerungen des gelagerten Drehrohres mitma- chen können. Abgesehen davon, dass die bekannte Gleitschuhlagerung infolge der kugelkalottenförmigen Sitze aufwendig in der Herstellung ist, kann die damit erreichte im Prinzip große Schwenkwinkelbeweglichkeit im Betrieb gar nicht genutzt werden, denn die Winkeländerungen des Drehrohrmantels sind relativ klein. Vielmehr ist es so, dass bei der bekannten Gleitschuhlagerung durch die geringe Schwenkwinkelbewegung am kugelkalottenförmigen Sitz die Gefahr nicht ausgeschlossen ist, dass dieser Sitz keine ausrei- chende Schmierung erhält. Denn infolge der nur ganz geringen Relativbewegung zwischen den sphärisch gewölbten Kalottensitzflächen ist es schwierig, die Schmierung der Sitzflächen zu gewährleisten, selbst wenn versucht wird, die kalottenförmigen Sitzflächen mit Drucköl zu versorgen, das aber aufgrund der geringen Relativbewe- gung der Sitzflächen keine ausreichende Gelegenheit hat, den Spalt zwischen den Sitzflächen auszufüllen.It is known to use large heavy rotary tubes such. B. tubular mills on several arranged around the lower rotary tube circumference arranged slide shoe bearing elements, the rotary tube being loaded on pads of pressure oil which is pressed into the lubrication gap between the slide bearing shoes and the radially supported rotary drum tread. It is e.g. For example, it is known from US-A-4,322,116 to provide the underside of the slide shoe bearing elements with spherically curved or spherical cap-shaped surfaces, by means of which the respective slide shoe bearing element is supported on the respective bearing block, the upper side of which is also provided with correspondingly spherically curved surfaces , Due to the spherical cap-shaped seat, the slide shoe bearing elements should be able to take part in changes in the angle of inclination or other changes in the angle of the mounted rotary tube. In addition to the fact that the known slide shoe mounting is complex to manufacture due to the spherical-spherical seats, the large pivoting angle mobility achieved in this way can in principle not be used during operation, because the changes in angle of the rotary tube shell are relatively small. Rather, it is the case that in the known sliding shoe mounting due to the small pivoting angle movement on the spherical cap-shaped seat, the risk that this seat does not receive sufficient lubrication is not excluded. Because of the very slight relative movement between the spherically curved spherical seat surfaces, it is difficult to guarantee the lubrication of the seat surfaces, even if an attempt is made to supply the spherical spherical seat surfaces with pressure oil, but this does not have a sufficient opportunity due to the slight relative movement of the seat surfaces to fill the gap between the seats.
Der Erfindung liegt die Aufgabe zugrunde, für Drehtrommeln wie z. B. Rohrmühlen eine Gleitschuhlagerung zu schaffen, die einfach gebaut und kostengünstig herstellbar ist und bei der trotzdem gewährleistet ist, dass sie im Betrieb alle Winkelbewegungen des Drehtrommelmantels mitmachen kann.The invention is based, for rotary drums such. B. tube mills to create a slide shoe storage that is simple in construction and inexpensive to manufacture and that still ensures that it can take part in all the angular movements of the rotating drum shell during operation.
Diese Aufgabe wird gemäß der Erfindung mit einer Gleitschuhlage- rung mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved according to the invention with a sliding shoe bearing with the features of claim 1. Advantageous developments of the invention are specified in the subclaims.
Charakteristisch für die erfindungsgemäße Gleitschuhlagerung ist, dass zwischen dem mit Drucköl beaufschlagten Gleitschuhlagerele- ment und dem zugehörigen Lagerbock jeweils ein plattenförmiger elastischer Körper angeordnet ist, der in einem diesen umschließenden, zur Gleitlagerschuh-Unterseite hin offenen Gehäuse gekammert ist, wobei die Gleitlagerschuh-Unterseite das Gehäuse mit dem ge- kammerten elastischen Körper von oben kolbenartig verschließt. Da- bei hat der gekammerte plattenförmige elastische Körper eine solche Dicke, dass er wie ein Kugelgelenk für das radial abgestützte Gleitschuhlagerelement für alle im Drehrohrbetrieb vorkommenden Winkelverstellungen des Drehrohrmantels wirkt. Das heißt, bei der erfin- dungsgemäßen Gleitschuhlagerung ist gewährleistet, dass die Gleitschuhlagerelemente aufgrund der jeweiligen elastischen Körper alle Bewegungen des Drehrohrmantels mitmachen in dem Falle, dass sich der Neigungswinkel des Drehrohrmantels gegenüber der Horizontalen ändern und/oder dass sich der Drehrohrmantel während seiner Drehung um bestimmte Größen durchbiegen oder sonstwie verformen sollte.It is characteristic of the slide shoe bearing according to the invention that a plate-shaped elastic body is arranged between the slide shoe bearing element acted on with pressure oil and the associated bearing block, which is chambered in a housing surrounding it and open towards the bottom of the slide bearing shoe, the bottom of the slide bearing shoe being Housing with the chambered elastic body closed like a piston from above. The chambered plate-shaped elastic body has such a thickness that it acts like a ball joint for the radially supported slide shoe bearing element for all the angular adjustments of the rotary tube shell that occur in rotary tube operation. That is, with the invented The slide shoe bearing according to the invention ensures that the slide shoe bearing elements, due to the respective elastic body, take part in all movements of the rotary tube shell in the event that the angle of inclination of the rotary tube shell changes with respect to the horizontal and / or that the rotary tube shell bends or otherwise deforms during its rotation ,
Die gekammerten, plattenformigen, elastischen Körper verhalten sich in ihren allseitig geschlossenen Gehäusen nahezu inkompressibel wie eine druckbeaufschlagte Flüssigkeit, d. h. die jeweils radial abgestützten Gleitschuhlagerelemente ändern ihre Höhenlage nahezu nicht. Jedoch haben diese elastischen Körper eine entsprechende Dicke und sie sind räumlich elastisch verformbar, so dass sie für das abgestützte Gleitschuhlagerelement wie ein Kugelgelenk wirken, ohne dass es dazu eines aufwendigen Aufbaues mit sphärisch gewölbten Kugelkalottenflächen bedarf. Dabei arbeiten diese Kugelgelenke bei Winkelverstellungen des gelagerten Drehrohres selbsttätig und völlig betriebssicher, ohne dass diese Gelenklager geschmiert werden müssen.The chambered, plate-shaped, elastic bodies behave in their all-round closed housings almost incompressibly like a pressurized liquid, i. H. the radially supported slide shoe bearing elements almost do not change their altitude. However, these elastic bodies have a corresponding thickness and they are spatially elastically deformable, so that they act like a ball joint for the supported slide shoe bearing element without the need for a complex structure with spherically curved spherical cap surfaces. These ball joints work automatically and completely reliably with angular adjustments of the mounted rotary tube, without the need to lubricate these spherical bearings.
Die gekammerten elastischen Körper bleiben selbst bei hohen Pressbelastungen so formbeständig, dass kein elastisches Material an dem Spalt zwischen dem Gehäuse und der in das Gehäuse kolbenartig hineingepressten Gleitlagerschuh-Unterseite heraustreten kann, wobei aufwendige Abdichtungen entfallen.The chambered elastic bodies remain so dimensionally stable even at high press loads that no elastic material can emerge from the gap between the housing and the slide bearing shoe bottom pressed into the housing in the manner of a piston, with complex seals being dispensed with.
Die Erfindung und deren weitere Merkmale und Vorteile werden anhand des in der Zeichnung schematisch dargestellten Ausführungs- beispieles näher erläutert.The invention and its further features and advantages are explained in more detail with reference to the exemplary embodiment shown schematically in the drawing.
Die Zeichnung zeigt ausschnittsweise im Querschnitt den unteren Umfangsbereich eines großen schweren Drehrohres wie z. B. einer Rohrmühle, deren Drehrohr pro Lagerstation auf mehreren um den < unteren Drehrohrumfang verteilten mit Drucköl beaufschlagten Gleit- schuhlagerelementen gelagert sind, von denen eines, nämlich das unterste Element in der Zeichnung zu sehen sind.The drawing shows sections of the cross-section of the lower peripheral region of a large heavy rotary tube such. B. one Tube mill, the rotary tube of which is supported per bearing station on a plurality of slide shoe bearing elements distributed around the <lower rotary tube circumference and pressurized oil, one of which, namely the lowest element, can be seen in the drawing.
Gemäß der Zeichnung ist der Mantel 10 einer Rohrmühle an einer Lagerstation auf mehreren um den unteren Mantelumfang verteilten Gleitschuhlagerelementen radial abgestützt, von denen das unterste Gleitschuhlagerelement 11 dargestellt ist. Die Gleitschuhlagerele- mente 11 sind hydrodynamische Gleitlager, deren mit Drucköl beaufschlagbare bzw. gefüllten Lagerschalen der Außenkontur des Drehrohrmantels 10 angepasst sind. Wenn bei der hydrostatischen Anfahrschmierung eine positive Schmierspaltdicke gemessen wird, wird die Rohrmühle 10 angefahren, d. h. in Pfeilrichtung in Drehung versetzt.According to the drawing, the jacket 10 of a tube mill is supported radially at a storage station on a plurality of slide shoe bearing elements distributed around the lower jacket circumference, of which the lowermost slide shoe bearing element 11 is shown. The slide shoe bearing elements 11 are hydrodynamic slide bearings, the bearing shells of which pressurized or filled with pressure oil are adapted to the outer contour of the rotary tube shell 10. If a positive lubrication gap thickness is measured in the hydrostatic start-up lubrication, the tube mill 10 is started, i. H. rotated in the direction of the arrow.
Die um den Drehrohrumfang verteilten Gleitschuhlagerelemente 11 sind jeweils gegen einen Lagerbock 12 radial abgestützt, der wiederum gegen das Fundament abgestützt ist. Erfindungsgemäß ist nun zwischen dem Gleitschuhlagerelement 11 und dem zugehörigen Lagerbock 12 jeweils ein plattenförmiger elastischer Körper 13 angeordnet, der aus elastischem Kunststoff und/oder aus Gummimaterial besteht und der in einem diesen umschließenden, zur Unterseite des Gleitlagerschuhes 11 hin offenen Gehäuse 14 gekammert ist, wobei gemäß Ausführungsbeispiel dieses Gehäuse 14 als nach oben offene Ausnehmung des Lagerbocks 12 dargestellt ist. Die Unterseite des Gleitlagerschuhs 11 verschließt mit einem nach unten wie ein Kolben 15 vorspringender Ansatz kolbenartig das Gehäuse 14 mit dem gekammerten elastischen Körper 13.The sliding shoe bearing elements 11 distributed around the circumference of the rotary tube are each supported radially against a bearing block 12, which in turn is supported against the foundation. According to the invention, a plate-shaped elastic body 13 is now arranged between the slide shoe bearing element 11 and the associated bearing block 12, which consists of elastic plastic and / or rubber material and which is chambered in a housing 14 enclosing it and open towards the underside of the slide bearing shoe 11, whereby According to the exemplary embodiment, this housing 14 is shown as an upwardly open recess in the bearing block 12. The underside of the slide bearing shoe 11 closes the housing 14 with the chambered elastic body 13 in a piston-like manner projecting downward like a piston 15.
Der sich wie eine druckbeaufschlagte nahezu inkompressible Flüssigkeit verhaltende gekammerte plattenförmige Gummikörper 13 hat eine solche Dicke, dass er wie ein Kugelgelenk für das radial abge- stützte Gleitschuhlagerelement 11 für alle im Drehrohrbetrieb vorkommenden Winkelverstellungen des Drehrohrmantels 10 wirkt. Trotz Kugelgelenkigkeit ändert das Gleitschuhlagerelement 11 seine Höhenlage aber nicht.The chambered plate-shaped rubber body 13 which behaves like a pressurized, almost incompressible liquid has a thickness such that it acts like a ball joint for the radially supported slide shoe bearing element 11 acts for all angle adjustments of the rotary tube shell 10 which occur in rotary tube operation. Despite spherical articulation, the slide shoe bearing element 11 does not change its altitude.
Der gekammerte plattenförmige elastische Körper 13 kann in seiner Berandung eckig oder rund sein. Der plattenförmige Körper 13 kann abgesehen von Gummimaterial aus einem geeigneten elastischen Kunststoffmaterial bestehen, das sich ebenfalls wie eine druckbeauf- schlagte nahezu inkompressible Flüssigkeit verhält, selbst wenn es nicht gekammert ist. Außerdem besteht die Möglichkeit, den plattenformigen Körper 13 als einen Verbundkörper auszubilden, der aus elastischem Kunststoffmaterial und Gummimaterial zusammengesetzt ist. The chambered plate-shaped elastic body 13 can be angular or round in its boundary. Apart from rubber material, the plate-shaped body 13 can consist of a suitable elastic plastic material, which also behaves like a pressurized, almost incompressible liquid, even if it is not chambered. There is also the possibility of forming the plate-shaped body 13 as a composite body which is composed of elastic plastic material and rubber material.
