Abstract
Description
Stand der TechnikState of technology
Die Erfindung betrifft einen Generator nach der Gattung des unabhängigen Patentanspruchs.The The invention relates to a generator according to the preamble of the independent claim.
Aus
der
Eine derartige Anordnung ist ganz besonders dann erforderlich, wenn der Generator über ein Drehmomentübertragungsteil angetrieben wird, das keine axiale Kraftkomponente in der Läuferlagerung des Generators erzeugt.A Such an arrangement is particularly necessary if the Generator over a torque transmission part is driven that no axial force component in the rotor bearing Generator.
Auf Grund von Fertigungstoleranzen im Montageprozess ist die Einstellung der axialen Vorspannungskraft nicht hinreichend genau gewährleistet und ist darüber hinaus ein zusätzlicher Montageprozess. Der Einpassring hat darüber hinaus weitere Nachteile. Z. B. ist dieser großvolumig und erfordert eine Mindestwandstärke zwischen Loslager und Nabe. Die hohen bzw. großen Wandstärken führen zu einer großen nachteiligen Nachgiebigkeit in radialer Richtung. Dort gleiten darüber hinaus der Einpassring aus Kunststoff und ein sehr glatter Lageraußenring aus Stahl relativ zueinander, so dass eine nur unbefriedigende Axialdämpfung der Schwingungen in Richtung der Läuferachse die Folge ist. Nachteilig ist in diesem Zusammenhang, dass die axialen und radialen Schwingungen direkt an das Federelement weitergegeben werden, was in der Folge zu ausfallenden Federelementen führt.On The reason for manufacturing tolerances in the assembly process is the setting the axial preload force is not guaranteed with sufficient accuracy and is about it an additional one Assembly process. The fitting ring also has other disadvantages. For example, this is large-volume and requires a minimum wall thickness between floating bearing and hub. The high or large wall thicknesses lead to a large disadvantage Flexibility in the radial direction. There slide beyond the fitting ring made of plastic and a very smooth bearing outer ring made of steel relative to each other, so that only an unsatisfactory axial damping Vibrations in the direction of the rotor axis The result is. The disadvantage in this context is that the axial and radial vibrations passed directly to the spring element become, which leads to failing spring elements.
Vorteile der ErfindungAdvantages of invention
Der erfindungsgemäße Generator mit den Merkmalen des Hauptanspruchs hat den Vorteil, dass durch das am Lagerteil befestigte Dämpfungselement das Lager und damit auch das Federelement gegen Axial- und Radialschwingungen sehr gut gedämpft ist und somit die Lebensdauer des Federelements um ein Vielfaches verlängert wird.The generator according to the invention with the features of the main claim has the advantage that the damping element attached to the bearing part the bearing and thus the spring element against axial and radial vibrations very well steamed is and thus the life of the spring element many times over extended becomes.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen des Generators nach dem Hauptanspruch möglich.By those in the subclaims listed activities are advantageous developments of the generator according to the main claim possible.
Eine sichere und zuverlässige Befestigungsmöglichkeit ist dadurch gegeben, dass das Lagerteil zumindest eine Nut hat, in der zumindest ein Dämpfungselement befestigt wird.A safe and reliable mounting option is given by the fact that the bearing part has at least one groove, in the at least one damping element is attached.
Eine hohe Tragfähigkeit des Lagers und eine verbesserte Dämpfung wird erreicht, wenn das Lagerteil zwei voneinander axial beabstandete Nuten hat, in denen je ein ringförmiges Dämpfungselement angeordnet ist.A high load capacity of the bearing and improved damping is achieved when the bearing part has two axially spaced grooves, in which are each ring-shaped Damping element arranged is.
Eine sehr gute Abstimmung zwischen Dämpfung und Federung in der Nabe ist dann erhältlich, wenn durch das plastisch verformte Federelement und die dadurch im plastischen Bereich genutzte Federkennlinie des Federelements bei verhältnismäßig großem Federweg während der Montage in einem verhältnismäßig engen Kraftbereich eine gut definierte Axialkraft erreicht wird.A very good coordination between damping and suspension in the hub is available when through the plastic deformed spring element and thereby used in the plastic area Spring characteristic of the spring element with a relatively large travel during Assembly in a relatively tight Force range a well-defined axial force is achieved.
Weist das Federelement im plastischen Bereich eine Federkonstante c zwischen 18 und 70 N/mm auf, so wird über den Kompressionsweg des Federelements bei üblichen Toleranzen der Generatorbauteile eine hinreichend genaue Axialkraft durch das Federelement erzielt.has the spring element in the plastic area has a spring constant c between 18 and 70 N / mm, so is about the compression path of the spring element with usual tolerances of the generator components achieved a sufficiently accurate axial force by the spring element.
Eine besonders günstige kompakte Bauweise des Federelements ergibt sich dann, wenn nach einem elastischen Kompressionsweg zwischen 3 und 3,5 mm der plastische Bereich beginnt. Beginnt der plastische Bereich unterhalb von 1,5 mm, so sind die Toleranzen für die verspannten Bauteile so klein zu wählen, dass eine Fertigung zu teuer ist. Wird der elastische Kompressionsweg größer gewählt, so führt dies zu einer nicht erwünschten axialen Verlängerung der Nabe. Damit bei Ausnutzung des plastischen Bereichs das Federelement die Vorspannung beziehungsweise Axialkraft auf das Lager nicht zu groß wird, soll über einen plastischen Kompressionsweg zwischen 1,5 und 3,5 mm eine Axialkraftveränderung ΔFA von 100 N einstellbar sein. Die Axialkraft FA liegt in günstigen Fällen zwischen 350 N und 650 N. Liegt die Axialkraft niedriger, so wird die Lebensdauer des Loslagers stark beschränkt, da die Abrollbewegungen der Wälzkörper nicht ideal verlaufen. Ist die Axialkraft größer als 650 N, so sinkt die Lebensdauer des Lagers auf Grund der erhöhten Pressung der Wälzkörper zwischen den Lagerringen.A particularly cheap compact design of the spring element results if after a elastic compression path between 3 and 3.5 mm the plastic Area begins. The plastic range begins below 1.5 mm, so are the tolerances for to choose the clamped components so small that a production too is expensive. If the elastic compression path is chosen larger, this leads to an unwanted one axial extension the hub. So the spring element when the plastic area is used the preload or axial force on the bearing does not become too great, supposed about a plastic compression path between 1.5 and 3.5 mm an axial force change ΔFA of 100 N can be set. In favorable cases, the axial force FA is between 350 N and 650 N. If the axial force is lower, the lifespan of the floating bearing becomes longer severely limited, since the rolling movements of the rolling elements are not run ideally. If the axial force is greater than 650 N, it decreases Life of the bearing due to the increased pressure of the rolling elements between the bearing rings.
Das Federelement ist durch die Nabe zentriert. Dies hat den Vorteil, dass das Federelement nicht an der Bohrung der Nabe anliegt, es dadurch nicht zu einem Axialkraftverlust kommt, der die Axialkraft auf das Loslager verringern könnte.The spring element is centered by the hub. This has the advantage that the spring element is not in contact with the bore of the hub, this does not result in a loss of axial force that could reduce the axial force on the floating bearing.
Nach einer weiteren Ausgestaltung ist vorgesehen, dass das Federelement einen Trägerbereich hat, von dem zumindest ein Federarm ausgeht. Der Trägerbereich hat dabei die Aufgabe, als Zentrierelement zu wirken und bietet damit einen guten Halt für den zumindest einen Federarm. Eine besonders raumsparende Bauweise ergibt sich dadurch, dass sich der zumindest eine Federarm in peripherer Richtung erstreckt.To Another embodiment provides that the spring element has a carrier area, from which at least one spring arm originates. The carrier area has the task to act as a centering element and thus offers a good hold for the at least one spring arm. A particularly space-saving design results is characterized in that the at least one spring arm is peripheral Direction extends.
Um eine günstige Werkstoffausnutzung beim Federelement zu erreichen, ist vorgesehen, dass mit der Axialkraft belastete Querschnitte des Federelements im Wesentlichen gleichen mechanischen Spannungen ausgesetzt sind.Around a cheap one To achieve material utilization in the spring element is provided that cross sections of the spring element loaded with the axial force are subjected to essentially the same mechanical stresses.
