Description

Vereinigtes Segment- und Kugeldrucklager. Der Gegenstand der Erfindung betrifft ein Segmentdrucklager, das gegenüber bereits bekannt gewordenen Arten dadurch gekennzeichnet ist, daß ein zusätzliches auf beliebig abschaltbaren, mittels Preßflüssigkeit betriebenen Druckkolben ruhendes Kugellager beim Anfahren oder Auslaufen zur Entlastung der Drucksegmente die Druckabstützung übernimmt.United segment and thrust bearings. The subject of the invention relates to a segment thrust bearing, which compared to types that have already become known thereby is characterized in that an additional can be switched off at will, by means of pressing fluid operated pressure piston stationary ball bearing when starting up or coasting down for relief the pressure segments take over the pressure support.

Dies ist für Maschinen, die - wie beispielsweise Wasserturbinen - mit Achsialbelastung anfahren müssen, vorteilhaft, weil mit der Belastung des (Segment-) Drucklagers gewartet werden kann, bis nach Erreichen einer gewissen Maschinendrehzahl die Schmierung der druckabstützenden Segmente, die ihrerseits von der Drehzahl abhängt, infolge kontinuierlichen Fließens der Schmierflüssigkeit über die Drucksegmentflächen, voll in Gang ist.This is for machines that - such as water turbines - have to start with axial load, advantageous because the load on the (segment) Thrust bearing can be serviced until a certain machine speed has been reached the lubrication of the pressure-supporting segments, which in turn depends on the speed, as a result of the continuous flow of the lubricating fluid over the pressure segment surfaces, is in full swing.

Die Schwierigkeiten des Anfahrens mit hochbelasteten Lagern, die nach längeren Betriebspausen besonders groß sind und leicht zu Anfressungen führen könnten, werden hierdurch vermieden.The difficulties of starting up with heavily loaded bearings that are after longer breaks in operation are particularly large and could easily lead to pitting, are thereby avoided.

Das besonders vorgesehene Kugellager, das Anfahrlager, wird während der Anfahrperiode mit Hilfe von Preßflüss.igkeit durch Druckkolben angehoben, und zwar nur so weit, daß die Last durch das Anfahrkugellager aufgenommen wird und zwischen den Drucksegmenten und dem darüber befindlichen Laufring ein kleines Spiel (beispielsweise von einigen Millim.etern5 entsteht.The specially provided ball bearing, the start-up bearing, is used during the start-up period is raised with the help of press liquid by pressure pistons, and only so far that the load is absorbed by the starting ball bearing and between the pressure segments and the running ring above them a little play (for example of a few millimeters5 arises.

Nach einigen (etwa zwanzig) Umdrehungen wird die Druckflüssigkeit unter dem Kolben abgelassen, der Läufer senkt sich, und das Segginentdrucklager tritt in Tätigkeit.After a few (about twenty) revolutions, the hydraulic fluid will be drained under the piston, the runner lowers, and the segginent thrust bearing comes into action.

Der Gegenstand der Erfindung ist in beispielsweiser Ausführungsform auf der Zeichnung veranschaulicht. Das Segmentdrucklager kann aus zwei Reihen Drucksegmenten i und y bestehen. Durch Kugeln 3 werden die Segmente abgestützt. Die Unterstützung erfolgt beispielsweise durch einen Ring .4, auf dem ein Wagebalken 5 ruht, der den Druck der Kugeln auf den Ring übermittelt. Der Laufring ist mit & bezeichnet.The subject matter of the invention is in an exemplary embodiment illustrated on the drawing. The segment thrust bearing can consist of two rows of pressure segments i and y exist. The segments are supported by balls 3. Support takes place, for example, by a ring .4 on which a balance beam 5 rests, which the Pressure of the balls on the ring is transmitted. The race is marked with &.

Die Anfahrvorrichtung besteht aus einem Anfahrkugellager 7 und Preßflüssigkeitskolben 8 zum Reben und Senken des Anfahrlagers.The start-up device consists of a start-up ball bearing 7 and press fluid piston 8 for lifting and lowering the approach camp.

Die Demontage eines Seb-nentlagers der Erfindung, das - im Falle seiner Anwendung an einer Wasserturbine - im allgemeinen zwischen Turbine und dem darüberliegenden Generator anzuordnen sein wird, erfolgt, indem man den Läufer - ebenfalls mit Hilfe der Hebevorrichtung 7, 8 - anhebt. Man nimmt zunächst zwei Paare gegenüberliegender Drucksegmente heraus und ersetzt sie durch entsprechend bemessene Paßstücke. Ist dies geschehen, so wird der Läufer auf diese Paßstücke, die etwas höher sind als die weggenommenen Segmente, gesenkt, indem die Druckflüssigkeit unter dem Kolben 8 abgelassen wird. Die übrigen Segmente und die dazugehörigen Wagebalken können dann leicht ebenfalls herausgenommen werden.The dismantling of a sebum tank of the invention, which - in the case of his Use on a water turbine - generally between the turbine and the one above Generator will have to be arranged by placing the rotor - also with the help the lifting device 7, 8 - lifts. First take two pairs of opposite sides Print segments out and replace them with appropriately sized fittings. is If this happens, the runner will hit these fittings, which are slightly higher than the removed segments, lowered by the pressure fluid under the piston 8 is drained. The remaining segments and the associated balance beam can can then be easily removed as well.
