Abstract
Description
Die Erfindung betrifft ein Generatorgetriebe mit einer mittels einer Festlagerung und einer Loslagerung in einer Lageraufnahmestruktur gelagerten Abtriebswelle.The invention relates to a generator gearbox with a driven shaft mounted by means of a fixed bearing and a movable bearing in a bearing receiving structure.
Ein derartiges Generatorgetriebe mit einer Abtriebswelle ist aus der
Der Erfindung liegt die Aufgabe zugrunde, ein Generatorgetriebe mit einer Festlagerung und einer Loslagerung einer Abtriebswelle bereitzustellen, bei der die Loslagerung insbesondere hinsichtlich einer Anschmierung bei Lastsprüngen verbessert ist.The invention has for its object to provide a generator gear with a fixed bearing and a floating bearing an output shaft, in which the floating bearing is improved in particular with regard to a lubrication at load jumps.
Diese Aufgabe wird dadurch gelöst, dass die Loslagerung zwei nebeneinander liegende Zylinderrollenlager aufweist. Gegenüber einen Einzellager können die einzelnen Komponenten der beiden nebeneinander liegenden Zylinderrollenlager kleiner und leichter dimensioniert werden und können daher schneller beschleunigt werden. Dies gilt insbesondere für die Zylinderrollen und deren Käfige. Dadurch wird die Lagerung insgesamt insbesondere bezüglich eines Anschmierverhaltens beim Anlaufen und/oder bei Lastsprüngen deutlich verbessert. So können beim Anlaufen und/oder bei Lastsprüngen des Generatorgetriebes auftretende Schlupfschäden an der als Hochgeschwindigkeitsabtriebswelle ausgebildeten Abtriebswelle beziehungsweise deren Lagerung, wirkungsvoll vermieden werden.This object is achieved in that the floating bearing has two adjacent cylindrical roller bearings. Compared to a single bearing, the individual components of the two adjacent cylindrical roller bearings can be sized smaller and lighter and can therefore be accelerated faster. This applies in particular to the cylindrical rollers and their cages. As a result, the storage is significantly improved overall, especially with respect to a lubrication when starting and / or load jumps. Thus, damage occurring during start-up and / or load jumps of the generator gear slip damage at the output shaft designed as a high-speed output shaft or its storage, can be effectively avoided.
In Weiterbildung der Erfindung weisen die zwei nebeneinander liegenden Zylinderrollenlager gleiche Dimensionen auf. Dadurch weisen beide Zylinderrollenlager sehr ähnliche oder sogar gleiche Betriebsverhalten auf, was für einen zuverlässigen Betrieb vorteilhaft ist. Ganz bevorzugt werden baugleiche Zylinderrollenlager verwendet, so dass einerseits hinsichtlich einer Bevorratung die Teilevielfalt nicht erhöht ist und andererseits bei der Montage keine besondere Aufmerksamkeit bei der Zusammenstellung der einzelnen Zylinderrollenlager erforderlich ist.In a further development of the invention, the two adjacent cylindrical roller bearings have the same dimensions. As a result, both cylindrical roller bearings have very similar or even the same operating behavior, which is advantageous for reliable operation. Quite preferably identical cylindrical roller bearings are used, so that on the one hand with respect to a stocking variety of parts is not increased and on the other hand during assembly no special attention is required in the compilation of the individual cylindrical roller bearings.
In weiterer Ausgestaltung der Erfindung entspricht die Summe der Tragzahlen der zwei nebeneinander liegenden Zylinderrollenlager zumindest der Tragzahl eines vergleichbaren Einzellagers. Durch diese Ausgestaltung ist sichergestellt, dass das Tragverhalten einer so erfindungsgemäßen modifizierten Loslagerung gegenüber dem Tragverhalten einer Loslagerung mit nur einem Zylinderrollenlager gleich oder sogar besser ist. Dabei bieten die zwei nebeneinander liegenden Zylinderrollenlager aber den Vorteil, dass diese kleiner und leichter als ein vergleichbares Einzellager dimensioniert werden können und dadurch das Anschmierverhalten deutlich verbessert wird.In a further embodiment of the invention, the sum of the load ratings of the two adjacent cylindrical roller bearings at least the load rating of a comparable single bearing. This embodiment ensures that the load-bearing behavior of a so-modified modified floating bearing according to the invention compared with the load-bearing behavior of a floating bearing with only one cylindrical roller bearing is the same or even better. However, the two adjacent cylindrical roller bearings offer the advantage that they can be dimensioned smaller and lighter than a comparable single bearing and thus the lubrication behavior is significantly improved.
In weiterer Ausgestaltung der Erfindung sind die Rollendurchmesser der Zylinderrollen jedes der beiden nebeneinander liegenden Zylinderrollenlager gleich. Auch diese Ausgestaltung trägt dazu bei, dass das Betriebsverhalten der beiden nebeneinander liegenden Zylinderrollenlager gleich ist.In a further embodiment of the invention, the roller diameter of the cylindrical rollers of each of the two adjacent cylindrical roller bearings are the same. This embodiment also contributes to the fact that the operating behavior of the two adjacent cylindrical roller bearings is the same.
In einer alternativen Ausgestaltung der Erfindung können die Rollendurchmesser der Zylinderrollen und/oder die Durchmesser der Außenringe und Innenringe jedes der beiden nebeneinander liegenden Zylinderrollenlager sich minimal, insbesondere im μm-Bereich unterscheiden. Dabei hat dann beispielsweise ein Zylinderrollenlager ein größeres Lagerspiel als das nebenliegende Zylinderrollenlager. Dies kann beispielsweise bei auf die Abtriebswelle einwirkenden Biegebelastungen vorteilhaft sein.In an alternative embodiment of the invention, the roller diameters of the cylindrical rollers and / or the diameters of the outer rings and inner rings of each of the two adjacent cylindrical roller bearings may differ minimally, in particular in the micron range. In this case, then, for example, a cylindrical roller bearing has a larger bearing clearance than the adjacent cylindrical roller bearing. This may be advantageous, for example, when acting on the output shaft bending loads.
In Weiterbildung der Erfindung ist der Rollendurchmesser der Zylinderrollen der beiden nebeneinander liegenden Zylinderrollenlager kleiner, insbesondere 5 bis 20%, ganz besonders angenähert 12% kleiner als der Rollendurchmesser eines vergleichbaren Einzellagers. Beispielsweise kann der Durchmesser der Zylinderrollen von 42 mm auf 37 mm reduziert werden. Mit solchermaßen ausgestalteten nebeneinander liegenden Zylinderrollenlagern lässt sich die gleiche Tragzahl wie bei einem vergleichbaren Einzellager darstellen, wobei aber das Trägheitsmoment der so ausgebildeten Loslagerung um bis zu ca. 40% geringer als bei einer Einzellagerung ist. Dadurch, dass der Rollendurchmesser verringert ist, können mehr Zylinderrollen zwischen dem Innenring und dem Außenring eingebaut werden, die eine bessere Lastverteilung in der Loslagerung gewährleisten. Dadurch werden die dynamischen Eigenschaften der zwei nebeneinander liegenden Zylinderrollenlager deutlich verbessert. Die Vergrößerung der Anzahl der Zylinderrollen von beispielsweise 14 Zylinderrollen bei einem herkömmlichen Einzellager auf jeweils 16 Zylinderrollen bei den beiden nebeneinander liegenden Zylinderrollenlagern ermöglicht eine Trägheitsreduzierung im Bereich von angenähert 10% bei jedem Rollensatz.In a further development of the invention, the roller diameter of the cylindrical rollers of the two adjacent cylindrical roller bearings is smaller, in particular 5 to 20%, very particularly approximately 12% smaller than the roller diameter of a comparable single bearing. For example, the diameter of the cylindrical rollers can be reduced from 42 mm to 37 mm. With thus designed side by side cylindrical roller bearings leaves represent the same load rating as a comparable single bearing, but the moment of inertia of the so-formed floating bearing is up to about 40% less than in a single bearing. The fact that the roll diameter is reduced, more cylindrical rollers between the inner ring and the outer ring can be installed, which ensure a better load distribution in the floating bearing. This significantly improves the dynamic properties of the two adjacent cylindrical roller bearings. The increase in the number of cylindrical rollers of, for example, 14 cylindrical rollers in a conventional single bearing on 16 cylindrical rollers in the two adjacent cylindrical roller bearings allows an inertia reduction in the range of approximately 10% in each set of rollers.
In weiterer Ausgestaltung der Erfindung ist jedes der nebeneinander liegenden Zylinderrollenlager ein Zylinderrollenlager in der Bauart N, NU oder NJ. Diese Bauarten haben sich als besonders geeignet erwiesen. Weiterhin ist jedes der nebeneinander liegenden Lager ein HC-Lager. Ein solches HC-Lager (High-Capacity-Lager) weist einen massenträgheitsoptimierten Käfig für die Zylinderrollen auf, was ebenfalls zu einem verbesserten Betriebsverhalten führt.In a further embodiment of the invention, each of the adjacent cylindrical roller bearings is a cylindrical roller bearing in the type N, NU or NJ. These types have proven to be particularly suitable. Furthermore, each of the adjacent bearings is an HC bearing. Such a HC bearing (high-capacity bearing) has a mass inertia-optimized cage for the cylindrical rollers, which also leads to improved performance.
In weiterer Ausgestaltung der Erfindung ist ein gekoppelter Käfig für die beiden nebeneinander liegenden Zylinderrollenlager vorhanden. Ein gekoppelter, oder ein in weiterer Ausgestaltung vorgesehener einteiliger Käfig in Form eines Doppelkäfigs für die beiden nebeneinander liegenden Zylinderrollenlager stellt sicher, dass das dynamische Verhalten der beiden Zylinderrollenlager zumindest angenähert gleich ist, was wiederum auch vorteilhafte Auswirkungen auf das Betriebsverhalten und somit das Anschmierverhalten der beiden Zylinderrollenlager mit sich bringt. Bei dem gekoppelten Käfig sind die beiden Käfige für die Zylinderrollenlager prinzipiell eigenständig ausgebildet, und werden beispielsweise bei der Montage der Zylinderrollenlager in geeigneter Weise miteinander verbunden oder greifen beispielsweise durch seitliche Stifte ineinander. Bei beiden Ausführungen ist der Durchmesser des Käfigs kleiner als der Durchmesser eines herkömmlichen Käfigs eines Einzellagers. Weiterhin ist zumindest ein Käfig am Innenring, am Außenring oder an den Zylinderrollen geführt und das Material des Käfigs ist Blech, wobei der Käfig als Blech-Stanz-Biegeteil ausgebildet ist. Ein solcher Käfig ist einfach herstellbar, dabei leicht und passgenau.In a further embodiment of the invention, a coupled cage for the two adjacent cylindrical roller bearings is present. A coupled, or provided in a further embodiment, one-piece cage in the form of a double cage for the two adjacent cylindrical roller bearings ensures that the dynamic behavior of the two cylindrical roller bearings is at least approximately equal, which in turn also beneficial effects on the performance and thus the Anschmierverhalten the two Cylindrical roller bearing brings with it. In the coupled cage, the two cages for the cylindrical roller bearings are basically formed independently, and are for example in the assembly of the cylindrical roller bearings connected in a suitable manner or engage, for example, by lateral pins into one another. In both embodiments, the diameter of the cage is smaller than the diameter of a conventional cage of a single bearing. Furthermore, at least one cage is guided on the inner ring, on the outer ring or on the cylindrical rollers and the material of the cage is sheet metal, wherein the cage is designed as a sheet-metal stamped and bent part. Such a cage is easy to produce, while easy and accurate.
In Weiterbildung der Erfindung ist das Generatorgetriebe Teil eines Strömungskraftanlagengetriebes, insbesondere eines Meeresströmungskraftanlagengetriebes oder eines Windkraftanlagengetriebes. Bei solchen Strömungskraftanlagengetrieben ist die Erfindung besonders vorteilhaft umsetzbar, da es bei den hier verbauten großen Getrieben auf eine besondere Robustheit der verbauten Teile ankommt. Diese Robustheit wird durch die Verbesserung des Anschmierverhaltens erhöht.In a further development of the invention, the generator transmission is part of a flow force transmission, in particular a sea current power transmission or a wind turbine gearbox. In such Strömungsananlagengetrieben the invention is particularly advantageous feasible, since it depends on the built-in large gearboxes here on a particular robustness of the installed parts. This robustness is increased by improving the greasing behavior.
