Description

Großgetriebe einer Windkraftanlage  Large gearbox of a wind turbine
Die Erfindung betrifft ein Großgetriebe insbesondere einer Windkraftanlage mit einer den Getriebeölsumpf abschließenden unteren Ölwanne. The invention relates to a large transmission in particular a wind turbine with a transmission oil sump final lower oil pan.
Getriebe, insbesondere Großgetriebe, die in kalten Umgebungen betrieben werden, müssen vor Betriebsbeginn aufgeheizt werden, damit das Getriebeöl sich in einem optimalen Viskositätsbereich befindet, um alle Lagerstellen und Zahneingriffe mit einem Ölfilm zu benetzen. Hierfür werden in der Regel Gearboxes, especially large gearboxes operating in cold environments, must be heated before starting operation so that the gearbox oil is within an optimum viscosity range to wet all bearings and gear meshes with an oil film. For this are usually
Heizstäbe mit limitierter Oberfläche zur Wärmezufuhr eingesetzt. Daher dauert der Aufheizprozess hierbei sehr lange, zumal die Temperatur an der Oberfläche der Heizstäbe nicht zu hoch sein darf, um das Öl nicht zu beschädigen. Heating rods with limited surface used for heat supply. Therefore, the heating process takes a very long time, especially since the temperature at the surface of the heating elements must not be too high, so as not to damage the oil.
Aufgabe der Erfindung ist es, ein Großgetriebe der eingangs genannten Art so zu verbessern, dass nach einem Stillstand des Getriebes dieses sehr schnell wieder einsetzbar ist. The object of the invention is to improve a large transmission of the type mentioned so that after a standstill of the transmission this is very quickly used again.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass über dem Boden der Ölwanne eine das Öl erwärmende elektrische Heizfolie angeordnet ist. This object is achieved in that above the bottom of the oil pan an oil heating electric heating foil is arranged.
Um das Aufheizen des Öls zu beschleunigen und dadurch den Energiesatz und die Vorlaufzeit zur Inbetriebsetzung von Großgetrieben und angeschlossenen Maschinen zu beschleunigen, wird eine großflächige, flexible Heizfolie im In order to accelerate the heating of the oil and thereby accelerate the energy rate and the lead time for the commissioning of large gearboxes and connected machines, a large, flexible heating foil in the
Getriebeölsumpf eingebracht. Aufgrund der deutlich größeren Oberfläche kann das Öl bei geringerer Oberflächentemperatur schneller aufgeheizt werden. Gear oil sump introduced. Due to the significantly larger surface area, the oil can be heated up faster at a lower surface temperature.
Hierbei kann die Heizfolie auf dem Boden der Ölwanne aufliegen. Alternativ kann die Heizfolie in einem Abstand zum Boden angeordnet sein. Hierbei ist die In this case, the heating foil can rest on the bottom of the oil pan. Alternatively, the heating foil can be arranged at a distance to the ground. Here is the
BESTÄTIGUNGSKOPIE Heizfolie vorzugsweise parallel oder schräg zum Boden angeordnet. Auch kann die Heizfolie gewölbt und/oder gewellt geformt sein. CONFIRMATION COPY Heating foil preferably arranged parallel or obliquely to the ground. Also, the heating foil may be curved and / or wavy shaped.
Vorzugsweise ist dabei der Abstand zwischen der Oberseite des Bodens der Ölwanne und der Unterseite der Heizfolie 10 bis 50 mm. Hierbei können im Abstand Vorsprünge insbesondere Rippen des Bodens angeordnet sein. Preferably, the distance between the top of the bottom of the oil pan and the underside of the heating foil is 10 to 50 mm. In this case, projections, in particular ribs of the bottom, can be arranged at a distance.
Die Wärmeübertragung wird verbessert, wenn die Folie zahlreiche The heat transfer is improved when the film numerous
Durchbrechungen insbesondere Öffnungen aufweist. Vorzugsweise ist die Fläche der Heizfolie großflächig ausgeführt vorzugsweise mindestens so groß wie die Bodenfläche der Ölwanne. Ferner kann der Außenrand der Heizfolie die unteren Ränder der Ölwannenseitenwände bedecken. Openings in particular openings. Preferably, the surface of the heating foil is executed over a large area preferably at least as large as the bottom surface of the oil pan. Further, the outer edge of the heating foil may cover the lower edges of the oil pan sidewalls.
Eine optimale Temperaturregelung und -Steuerung wird erreicht, wenn in der Ölwanne unterhalb des Ölspiegels ein Temperatursensor angeordnet ist. Optimal temperature control and control is achieved when a temperature sensor is located in the oil sump below the oil level.
Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen schematisch dargestellt und wird im Folgenden näher beschrieben. Es zeigen An embodiment of the invention is shown schematically in the drawings and will be described in more detail below. Show it
Fig. 1 einen Querschnitt durch das Großgetriebe, 1 shows a cross section through the large transmission,
Fig. 2 einen Längsschnitt durch das Großgetriebe. Fig. 2 is a longitudinal section through the large transmission.
Großgetriebe werden u.a. in Windkraftanlagen, Schienenfahrzeugen, Large gearboxes are u.a. in wind turbines, rail vehicles,
Schiffsantrieben und im Bergbau eingesetzt. Hierbei geschieht es häufig, dass das Getriebe längere Zeit stillsteht und abkühlt. Vor einem erneuten Ship propulsion and used in mining. In this case, it often happens that the transmission stops and cools for a long time. Before a renewed
Betriebsbeginn müssen die ca. 200 bis 800 Liter Getriebeöl in der Ölwanne ausreichend erwärmt werden, um das Getriebeöl und das Getriebe zu schonen. Starting operation, the approx. 200 to 800 liters of transmission oil in the sump must be heated sufficiently to protect the transmission oil and the gearbox.
Hierzu ist auf der Oberfläche des Bodens der Getriebeölwanne 1 eine elektrische Heizfolie (einstückig oder mehrteilig) befestigt, die großflächig das Getriebeöl erwärmt, das die Zahnräder 3 schmiert und bei Stillstand des Großgetriebes das Getriebeölniveau 4 erreicht. Die Oberflächentemperatur der Heizfolie bleibt hierbei unter 80 Grad Celsius und dennoch erfolgt die ausreichende Erwärmung in kurzer Zeit, da die Heizfolie eine große Fläche bildet. For this purpose, on the surface of the bottom of the transmission oil pan 1, an electric heating foil (integral or multi-part) attached, which heats the transmission oil over a large area, lubricates the gears 3 and reaches the transmission oil level 4 at standstill of the large transmission. The surface temperature of the heating foil remains in this case below 80 degrees Celsius and yet the sufficient heating takes place in a short time, since the heating foil forms a large area.
Vorzugsweise ist die Fläche der Heizfolie 2 mindestens so groß wie die Preferably, the surface of the heating foil 2 is at least as large as the
Bodenfläche der Ölwanne 4. In einer Ausführung ragt die Heizfolie über den Außenrand des Ölwannenbodens hinaus und bedeckt mit seinem Außenrand den unteren Rand der Ölwannenseitenwände. Bottom surface of the sump 4. In one embodiment, the heating foil projects beyond the outer edge of the sump bottom and covers with its outer edge the lower edge of the sump sidewalls.
Die Heizfolie 2 kann direkt ohne Abstand auf dem Boden befestigt sein. Alternativ kann sie aber auch mit der Bodenoberseite einen Abstand von vorzugsweise 10 bis 50 mm bilden, durch den das Öl strömen kann und damit noch schneller sich erwärmt. Ferner wird die Wärmeübertragung noch dadurch beschleunigt, wenn in diesem Abstand Rippen des Bodens vorstehen und/oder in der Heizfolie 2 sich Durchbrechungen/Öffnungen befinden. The heating foil 2 can be attached directly without clearance on the floor. Alternatively, however, it may also form a distance of preferably 10 to 50 mm with the bottom top side, through which the oil can flow and thus heats up even faster. Furthermore, the heat transfer is further accelerated if at this distance ribs of the bottom project and / or in the heating foil 2 openings / openings are.
Mindestens ein Temperatursensor 5 erfasst die aktuelle Öltemperatur, so dass nach Erreichen der geforderten Öltemperatur die Maschine oder das Windrad mit dem Großgetriebe anlaufen kann. At least one temperature sensor 5 detects the current oil temperature, so that after reaching the required oil temperature, the machine or the wind turbine can start with the large transmission.
