Description

Konvertergetriebeconverter gear
Die Erfindung betrifft ein Konvertergetriebe, umfassend einen mit der Schwenkachse eines Konvertergefäßes verbundenen Zahnkranz im Eingriff mit wenigstens einem Antriebs-Zahnritzel des Konvertergetriebes, und wenigstens eine in die Verzahnung des Zahnkranzes ein- oder ausschwenkbare Blockiervorrich- tung in Form eines an einer horizontalen Welle angeordneten, mit einer Verzahnung ausgebildeten Blockierarmes.The invention relates to a converter gear, comprising a gear ring connected to the pivot axis of a converter vessel in engagement with at least one drive pinion of the converter gear, and at least one blocking device in the form of a locking device arranged on a horizontal shaft, which can be swiveled in or out of the toothing of the gear ring. with locking teeth trained blocking arm.
Konvertergetriebe werden während des Sauerstoff-Einblasvorganges durch hohe und wechselnde Momente belastet. Diese führen in der Regel zu extrem hoher Flächenbelastung und damit zu übermäßigem Verschleiß an den Verzahnungen.Converter gearboxes are subjected to high and changing moments during the oxygen injection process. As a rule, these lead to extremely high surface loads and thus excessive wear on the gears.
Es ist bekannt, die schädliche Belastung durch Einsatz eines Blockierarmes deutlich zu reduzieren. Dessen endständige Blockierarmverzahnung zum blok- kierenden Eingriff in die Verzahnung des Zahnkranzes am Konvertergefäß entspricht als "Negativ-Form" etwa 5 bis 6 Zahnlücken des Abtriebsrades. Die hierbei gleichmäßig auf einen Bereich der Verzahnung verteilte Last ergibt eine signifikante Reduzierung der Flächenpressung derselben und des damit verursachten Verschleißes.It is known to significantly reduce the harmful load by using a blocking arm. Its locking arm toothing for blocking engagement in the toothing of the ring gear on the converter vessel corresponds as a "negative form" to about 5 to 6 tooth gaps of the driven gear. The load that is evenly distributed over an area of the toothing results in a significant reduction in the surface pressure of the same and the wear caused thereby.
Nachteilig an dieser Konstruktion ist eine erforderliche Einstellgenauigkeit des Blockierhebels und seiner Lagerung, insbesondere bei Anordnung zweier unabhängiger Blockierhebel. Hierbei können bereits geringe Abweichungen von der idealen Eingriffsposition zu extrem hohen Zwängen und Spannungen und damit zu einem schnelleren Verschleiß am Zahnkranz und an der Blockierarmverzahnung führen. Um diese Folgen zu vermeiden, wurde von der Maßnahme Gebrauch gemacht, Gehäuse- und Blockierarmbohrung gemeinsam zu bearbeiten. Hierzu ist es erforderlich, Zahnrad und Blockierarm in ihrer optimalen Position im Gehäuse vorzumontieren, sodann zu fixieren und zuletzt gemeinsam zu bearbeiten.A disadvantage of this construction is the required setting accuracy of the locking lever and its mounting, especially when two independent locking levers are arranged. Even slight deviations from the ideal engagement position can lead to extremely high constraints and tensions and thus to faster wear on the ring gear and the locking arm teeth. In order to avoid these consequences, use was made of the measure of machining the housing and blocking arm holes together. For this it is necessary to pre-assemble the gear and blocking arm in their optimal position in the housing, then to fix them and finally to work together.
Dabei ergibt sich außer den sehr hohen Fertigungskosten der weitere Nachteil, dass ein späterer Austausch bzw. eine Nachjustierung des Blockierarmes infolge der besonderen Bearbeitungsfolge nicht möglich ist.In addition to the very high manufacturing costs, there is the further disadvantage that a later replacement or readjustment of the blocking arm is not possible due to the special processing sequence.
Das Dokument EP 1 022 482 A1 beschreibt eine Vorrichtung zum Blockieren eines Elementes einer kinematischen Kette an einer Gießpfanne, umfassend ein Bauteil mit an seiner Peripherie vorgesehenem Bereich reliefartiger Erhöhungen und Vertiefungen, komplementär zu Bereichen mit reliefartigen Vertiefungen und Erhöhungen an dem zu blockierenden Element, und, angeordnet am Ende eines Blockierarmes, eine Vorrichtung zum Versetzen des Bauteils zwischen einer passiven Position "außer Eingriff" mit dem zu blockierenden Element, und einer aktiven Position, bei der sich die erhöhten und vertieften Bereiche des Elementes bzw. des Bauteils einander durchdringen, um das Element in einer vorbestimmten Position zu blockieren. Ferner sind Anzeige- mittel für das Element in der vorgegebenen Position hinsichtlich seiner erhöhten und vertieften Bereiche, sowie Mittel zur Anzeige der Position des Blockierarmes vorgesehen.Document EP 1 022 482 A1 describes a device for blocking an element of a kinematic chain on a ladle, comprising a component with an area of relief-like elevations and depressions provided on its periphery, complementary to areas with relief-like depressions and elevations on the element to be blocked, and , arranged at the end of a blocking arm, a device for moving the component between a passive position "out of engagement" with the element to be blocked, and an active position in which the raised and depressed regions of the element or the component penetrate each other to block the element in a predetermined position. In addition, display means are provided for the element in the predetermined position with regard to its raised and lowered areas, and means for displaying the position of the blocking arm.
Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Auf- gäbe zugrunde, ein Konvertergetriebe der im Oberbegriff von Anspruch 1 genannten Art in verbesserter Bauart herzustellen und mit Mitteln für die Einstellung einer idealen Eingriffsposition der Verzahnung zwischen Antriebsritzel und Zahnkranz derart auszubilden, dass die optimale Einstellgenauigkeit des Blok- kierhebels relativ zum Zahnkranz des Getriebes jederzeit unabhängig von der Fertigung dieser Elemente nachjustiert werden kann. Zur Lösung der Aufgabe wird bei einem Konvertergetriebe der eingangs genannten Art mit der Erfindung vorgeschlagen, dass die Welle des Blockierarms in wenigstens einem endständigen Lager gelagert und der Blockierarm mittels Kraftmitteln in die Verzahnung des Zahnkranzes kraftschlüssig einrückbar, bzw. aus dem Eingriff der Verzahnung ausrückbar ist, und dass die Welle des Blok- kierarmes mit jeweils zwei ineinander frei drehbar angeordneten Exzenterbuchsen an ihren Wellenenden im Gehäuse des Konvertergetriebes gelagert ist, derart, dass durch unabhängiges Verdrehen derselben eine gegenseitige ideale Eingriffsposition der beiden zusammenwirkenden Verzahnungsbereiche der Blockiervorrichtung sowie des Zahnkranzes einstellbar ist.Starting from the aforementioned prior art, the invention is based on the tasks of producing a converter gear of the type mentioned in the preamble of claim 1 in an improved design and using means for setting an ideal engagement position of the toothing between the drive pinion and ring gear in such a way that the optimum Setting accuracy of the blocking lever relative to the gear rim of the gear can be readjusted at any time regardless of the manufacture of these elements. In order to achieve the object, the invention proposes in a converter gearbox of the type mentioned at the outset that the shaft of the blocking arm is mounted in at least one terminal bearing and the blocking arm can be positively engaged in the toothing of the toothed ring by means of force means or disengaged from the engagement of the toothing , and that the shaft of the blocking arm, each with two eccentric bushings freely rotatably arranged one inside the other, is mounted at its shaft ends in the housing of the converter gear, in such a way that an independent ideal engagement position of the two interacting toothed areas of the blocking device and of the ring gear can be set by independently rotating them.
Mit großem Vorteil wird durch die erfindungsgemäße Bauart der Lagerung des Blockierarmes erreicht, dass eine optimale Einstellbarkeit des Zahnspiels der Antriebsverzahnung des Getriebes jederzeit und unabhängig von dessen Fertigung erzielt wird und/oder das Zahnspiel nachjustiert werden kann. Damit ergibt sich eine gleichmäßige Lastverteilung im Bereich der Blockierverzahnung bei etwa 5 bis 6 Zahnlücken des Eingriffsbereichs des Abtriebrades mit drastisch reduzierter Flächenbelastung der Zahnflanken. Der Verschleiß der Getriebezahnräder wird entsprechend reduziert.With the design according to the invention of the mounting of the blocking arm, it is achieved with great advantage that an optimal adjustability of the tooth play of the drive toothing of the transmission is achieved at any time and independently of its manufacture and / or the tooth play can be readjusted. This results in a uniform load distribution in the area of the locking teeth with approximately 5 to 6 tooth gaps in the area of engagement of the driven wheel with a drastically reduced surface load on the tooth flanks. Wear on the gearwheels is reduced accordingly.
Zweckmäßige Ausgestaltungen der erfindungsgemäßen Lagerung sind entsprechend den Unteransprüchen vorgesehen.Appropriate configurations of the storage according to the invention are provided in accordance with the subclaims.
