Abstract
Description
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 kugelgelenkig gegen einen Lagerbock radial abgestützt sind.The invention relates to a sliding shoe storage for rotary drums such as B. for a tube mill whose Rotary tube per storage station on several around the lower circumference of the rotary tube distributed pressurized oil Sliding shoe bearing elements is mounted, each ball-jointed are supported radially 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
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 ausreichende 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 Relativbewegung der Sitzflächen keine ausreichende Gelegenheit hat, den Spalt zwischen den Sitzflächen auszufüllen.Rather, it is the case with the known slide shoe storage due to the small swivel angle movement on spherical cap Seat the risk is not excluded that this seat is not sufficient Receives lubrication. Because due to the very slight relative movement between the spherically curved spherical seat surfaces it is difficult to ensure the lubrication of the seats, even if tried will, the dome-shaped seats with pressure oil to supply, but none due to the small relative movement of the seat surfaces has sufficient opportunity 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 on the object for rotary drums such as B. tube mills to create a slide shoe storage that is simple to build and inexpensive to manufacture is and is still guaranteed is that they operate all angular movements of the rotating drum jacket can participate.
Diese Aufgabe wird gemäß der Erfindung mit einer Gleitschuhlagerung mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved according to the invention solved 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 Gleitschuhlagerelement 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 gekammerten elastischen Körper von oben kolbenartig verschließt. Dabei 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.Characteristic for the slide shoe storage according to the invention is that between that with pressure oil loaded slide shoe bearing element and the associated bearing block each a plate-shaped elastic body is arranged in a surrounding this to the plain bearing shoe bottom open housing is chambered, the bottom of the plain bearing shoe with the housing the chambered elastic body sealed like a piston from above. The chambered plate-shaped elastic body has one such a thickness that it acts like a ball joint for the radially supported slide shoe bearing element for all Angle adjustments of the rotary tube jacket occurring in rotary tube operation acts. This means, in the inventive slide shoe storage is guaranteed that the sliding shoe bearing elements due to the respective elastic body participate in all movements of the rotary tube casing in the event that the angle of inclination of the rotary tube shell compared to the Change horizontal and / or that the rotary tube jacket determined itself during its rotation Bend sizes or otherwise deform.
Die gekammerten, plattenförmigen, 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 body behave almost in their closed housings incompressible like a pressurized liquid, d. H. each radial supported Sliding shoe bearing elements change their altitude almost not. However, these elastic bodies have a corresponding thickness and they are spatial resiliently deformable so that it is for the supported slide shoe bearing element act like a ball joint without it being expensive Structure with spherical domed Kugelkalottenflächen requirement. These ball joints work with angular adjustments of the stored rotary tube automatically and completely reliably, without this Spherical bearings must be lubricated.
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 stable even under high press loads that no elastic Material at the gap between the housing and the piston-like in the housing Pressed-in bottom of the plain bearing shoe can come out, whereby there is no need for complex seals.
Die Erfindung und deren weitere Merkmale und Vorteile werden anhand des in der Zeichnung schematisch dargestellten Ausführungsbeispieles näher erläutert.The invention and its further features and Advantages are shown schematically in the drawing Embodiment explained in more detail.
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 Gleitschuhlagerelementen 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 area of a large heavy rotary tube such. B. a tube mill, the rotary tube per bearing station on several distributed around the lower rotary tube circumference loaded with pressure oil loaded slide bearing elements are, of which one, namely the bottom element can be seen in the drawing.
