Description
Gleitlagerschale mit verstärkter Kühlung. Plain bearing shell with reinforced cooling.
Die Erfindung bezieht sich auf eine Gleitlagerschale mit verstärkter Kühlung, bestehend aus Stützkörper und Lagerschale, insbesondere für grosse elektrische Maschinen. The invention relates to a plain bearing shell with reinforced Cooling, consisting of a support body and bearing shell, especially for large electrical ones Machinery.
Muss ein Gleitlager zeigen hoher Reibungserwärmung zusätzlich gekühlt werden, so gehört es seit längerer Zeit zum Stand der Technik, entweder eine Spülölschmierung mit Rückkühlung des Oels oder eine direkte Kühlung der Lagerschale anzuwenden. Beide Systeme sind in etwa physikalisch gleichwertig, jedoch bietet die direkte Kühlung der Lagerschale besonders bei Einbauten in Wasserkraftwerken, wo geeignete Kühlmittel in ausrichendem Umfang zur Verfügung stehen, grosse Vorteile. A plain bearing must show high frictional heating in addition to being cooled it has been state of the art for a long time either with flushing oil lubrication with recooling of the oil or direct cooling of the bearing shell. Both Systems are roughly equivalent physically, but the direct cooling offers the bearing shell especially for installations in hydropower plants, where suitable coolants are available in sufficient quantities, great advantages.
Um eine wirksame Kühlung zu erzielen, sind bereits verschiedene Massnahmen zur Anwendung gekommen. So hat man unter anderem unmittelbar in den Lagerausguss de unteren Lagerschalenhälfte Rohre, die als Kühlmittelführung- verwendet werden, eingegossen. Various measures are already in place to achieve effective cooling came into use. So you have, among other things, directly into the storage sink the lower half of the bearing shell tubes, which are used as coolant ducts, poured.
Diese bekannte Anordnung weist jedoch verschiedene Mängel auf. Die wichtigsten davon sind, das-s die Lagerschale nach kurzer Betriebszeit nachgeschabt werden muss, da die eingegossenen Kühlrohre nachgeben und somit ein Nachschaben der Lagerschale erforderlich wird, der Lagermetallausguss inuss relativ dick gehalten werden, um die Rohre genügend einivetten zu können. Dadurch wird der Wärmeleitwert ungünstig beeinflusst. Ein weiterer erhebAicher Nachteil ist darin zu sehen, dass keinerlei Reinigungsmöglichkeiten der Kühlrohre vorhanden sind, sowie die verhältnismässig aufwendige Herstellung solcher Lagerschalen. However, this known arrangement has several shortcomings. the The most important of these are that the bearing shell is re-scraped after a short period of operation must become, because the cast-in cooling tubes give way and thus a scraping of the bearing shell is necessary, the bearing metal spout inuss be kept relatively thick in order to be able to einivetten the pipes sufficiently. Through this the thermal conductivity is adversely affected. Another significant disadvantage can be seen in the fact that there are no cleaning options for the cooling tubes are, as well as the relatively complex production of such bearing shells.
Es ist Aufgabe der Erfindung, eine Anordnung zu schaffen welche die Nachteile des Bekannten nicht aufweist. It is the object of the invention to provide an arrangement which the Does not have disadvantages of the known.
Dies kann dadurch erreicht werden, die bisher bekannten Lagerschalen durch dünnwandige Lagerschalen, die mit einem Stützkörper versehen sind, und Anordnungen zur Kühlmittelführung aufweisen, zu ersetzen.This can be achieved by using the previously known bearing shells through thin-walled bearing shells, which are provided with a support body, and arrangements for coolant supply have to be replaced.
Die vorgenannte Aufgabe zur erfindungsgemäss dadurch gelöst, dass über die gesamte Breite des Stützkörpers in gleichmässigen Abst,inden Rillen zur Führung des Kühlmittels angeordnet sind. Diese Rillen sind in der Nähe der Lagertrennstellen durch je einen Zuführungskanal miteinander verwunden, durch welchen die Rillen mit Kühlmittel versorgt werden. Zwischen der l,agerschale und dem Stützkörper sind an den Lageraussenseiten Dichtungsmittel vorgesehen, die ein Austreten des Kühlmittels an den Lagerseiten verhindern. The aforementioned object is achieved according to the invention in that over the entire width of the support body at a uniform distance, in the grooves for Guide of the coolant are arranged. These grooves are near the bearing separation points each twisted by a feed channel through which the grooves with Coolant are supplied. Between the oil shell and the support body are on Sealing means are provided on the outside of the bearing to prevent the coolant from escaping prevent on the bearing sides.
Das Kühlmittel wird in bekannter Weise den in der Nahe der Lagertrennstell en angeordneten Zuführungskanälen zugeleitet.The coolant is in a known manner in the vicinity of the Lagertrennstell en arranged feed channels fed.
Der Vorteil der Erfindung best-eht insbesondere darin, dass durch die Vielzahl der Rillen im Stützkörper eine intensive Kühlung des Lagers bzw. der Lagerschalen erreicht wird, so dass eine gleichmässige Wärmeabfuhr über die ganze Lageroberfläche erzielt wird. Es -ergeben sich keinerl-ei Wärmespannungen zwischen dem Lagermetall und dem Stützkörper des Lagers, ein Nachsnhaben der Lagerschale -wegen des Nachgebens der eingebetteten Kühlrohre ist nicht erforderlich und die Kühlkanäle und Rill-en können sehr leicht und gr-ündlich gereinigt werden. Ein ganz besond:erer Vorteil liegt in der einfachen und billigen Beratellung dieser gekühlten Gleitlager. The advantage of the invention consists in particular in the fact that through the large number of grooves in the support body provide intensive cooling of the bearing or the Bearing shells is achieved, so that a uniform heat dissipation over the whole Bearing surface is achieved. There are no thermal stresses between the bearing metal and the support body of the bearing, a Nachsnhaben the bearing shell -because of the yielding of the embedded cooling tubes is not required and the Cooling channels and grooves can be cleaned very easily and thoroughly. A very A particular advantage lies in the simple and cheap advice on these refrigerated products Bearings.
In der Zeichnung ist ein Ausführungsbeispie-l- des. Erfindungsgegenstandes -vereinfacht dargestellt. In the drawing, an exemplary embodiment is the subject of the invention -shown in simplified form.
Alle zum unmittelbaren Verständnis der Erfindung nicht notwendigen Konstruktionsmerkmale, beispielsweise die -Lagerbefestigun-gen und die Kühlmittelzuführungen, sind in der Zeichnung fortgelassen worden. All not necessary for a direct understanding of the invention Design features, for example the bearing mountings and the coolant supply, have been omitted from the drawing.
Zur Erläuterung der Wirkungsweise sei Fig. 1 näher betrachtet. Dort stellt dar: Eine dünnwandige Lagerschale 1 ist in einen Stützkörper 2 eingesetzt, in welchen Rillen 3 gleichmässig über die ganze Lagerbreite angeordnet sind. Diese Rillen 3 sind in der Nähe einer Lagertrennstelle 6 durch einen Kanal 5 miteinander verbunden. Zwischen der-Lagerschale 1 und dem Stützkörper 2 sind an den Lageraussenseiten 7 Dichtungsmittel 4 vorgesehen, die ein Austreten des Kühlmittels an den Lageraussenseiten 7 verhindern. To explain the mode of operation, FIG. 1 is considered in more detail. there shows: A thin-walled bearing shell 1 is inserted into a support body 2, in which grooves 3 are arranged evenly over the entire width of the bearing. These Grooves 3 are in the vicinity of a bearing separation point 6 through a channel 5 with each other tied together. Between the bearing shell 1 and the Support body 2 are on the bearing outer sides 7 sealing means 4 are provided, which prevent the coolant from escaping on the outside of the bearing 7.
