Description
Differential-Anstellvöxnchtung für Walzwerke Anstellvorrichtungen für Walzwerke, die auf verschiedene Hubgeschwindigkeiten einstellbar sind, sind in mehrfacher Ausführung bekannt. Man hat auch schon vorgeschlagen, die verschiedenen Hubgeschwindigkeiten dadurch zustande zu bringen, daß man zwei unabhängig voneinander liegende Drehkräfte differential zusammenwüken läßt, von denen die eine an der Druckspindel, die andere an der Druckmutter der Einstellvorrichtung angreift. Die dabei erforderliche drehbare Lagerung dien Druckmutter in dem Walzenständer bedingt jedoch sehr große Gleitflächen, um die hohen Walzdrücke aufnehmen zu können, die die Mutter auf den Ständer übertragen muß. -Auch ist es sehr schwierig, bei diesen hohen Drücken das Schmiermittel auf den Gleitflächen zu halten. Die schwere Ausführung der Mutter erfordert ferner zu ihrer Beschleunigung große Antriebskräfte und entsprechend hohe Motorleistungen.Differential adjustment device for rolling mill adjustment devices for rolling mills that can be adjusted to different lifting speeds known in several versions. It has already been suggested that the various To bring about lifting speeds by having two independently of each other lying torsional forces can work together differently, one of which is on the pressure spindle, the other engages the pressure nut of the adjustment device. The necessary rotatable mounting serve pressure nut in the roll stand, however, requires very large ones Sliding surfaces in order to be able to absorb the high rolling pressures that the mother exerts on the Must transfer stand. -Also, it is very difficult to do that at these high pressures To keep lubricant on the sliding surfaces. The heavy execution of the mother also requires large and correspondingly high driving forces for their acceleration Engine performance.
Diese Mängel werden gemäß der Erßndung dadurch vermieden, daß der beiden. Druckspindeln gemeinsamen Antriebswelle ein Differentialgetriebe an sich bekannter Ausführung vorgeschaltet wird, auf "das die beiden Drehkräfte je nach ihrer Richtung additiv oder subtraktiv reinwirken. Bei dieser Bauart bleibt die Anstellmutter in üblicher Weise fest im Ständer, und @es werden lediglich die Spindeln. angetrieben.These deficiencies are avoided according to the invention in that the both. Pressure spindles common drive shaft a differential gear in itself known design is connected upstream, on "which the two rotational forces depending on have an additive or subtractive effect in their direction. With this type of construction, the Adjusting nut firmly in the stand in the usual way, and only the spindles are used. driven.
Die Verwendung von Differentialgetrieben für Anstellvorrichtungen für Walzwerke ist schon vorgeschlagen worden, um die beiden Spindeln ein und desselben Gerüstes mit verschiedenen Geschwindigkeit anzutreiben und damit einen Höhenausgleich der Walzen zu erzielen. Mit der der Erfindung zugrunde liegenden Aufgabe, den Anstellvorgang nach Belieben schnell oder langsam durchzuführen, hat dies nichts zu tun. In der Zeichnung ist der Gegenstand der Erfindung beispielsweise dargestellt: Abb. i ist ein senkrechter Schnitt und Abb. z ein GrundriB einer Differentialanstellung. Abb. 3 zeigt eine Einzelheit daraus.The use of differential gears for adjusting devices for rolling mills it has already been proposed to make the two spindles one and the same To drive the scaffolding at different speeds and thus a height compensation to achieve the rollers. With the object on which the invention is based, the adjustment process To do it quickly or slowly at will has nothing to do with it. In the Drawing shows the subject matter of the invention, for example: Fig. I is a vertical section and Fig. z a plan of a differential adjustment. Fig. 3 shows a detail of this.
Die beiden Druckspindeln a werden durch die Schneckenräder b in den im Ständer festen Druckmuttern c beim Anstellen gedreht. Der Antrieb der Schneckenräder erfolg, durch eine ihnen gemeinsame Welle,, die erfindungsgemäß ein; Differentialgetriebe f an sich bekannter Ausführung enthält.The two pressure spindles a are through the worm wheels b in the The pressure nuts c fixed in the stand are rotated when adjusting. The drive of the worm wheels success, through a wave common to them, which according to the invention a; Differential gear f contains known execution.
Die Schneckenräder des Differentialgetriebes werden unmittelbar von einem Motor d, sein Gehäuse über ein Vorgelege i von einem Motore in Drehung versetzt. Die Motorkupplungen sind, wie in Abb. 3 zu sehen ist, mit Bremsbündein h und k versehen.The worm gears of the differential gear are set in rotation directly by a motor d, and its housing is set in rotation by a motor via a back gear i. As can be seen in Fig. 3, the motor couplings are provided with brake collars h and k.
Je nachdem einer oder der andere der beiden Motoren d und e für sich oder beide gemeinsam im gleichen Sinne oder entgegengesetzt umlaufen, lassen sich im ganzen vier G.eschwindi.gkeitsstufes@ für die Antriebswellle.g der Spindeln a erzielen. Die Anstellgeschwindigkeyt der Walzen ist somit in weiten Grenzen regelbar.Depending on one or the other of the two motors d and e for themselves or both can be circulated together in the same sense or in opposite directions a total of four speed levels @ for the drive shaft of the spindles a achieve. The setting speed of the rollers can thus be regulated within wide limits.
Die Motoren d und e können durch andere Antriebe ersetzt werden, beispielsweise durch von Hand bewegte Antriebselemente.The motors d and e can be replaced by other drives, for example by drive elements moved by hand.
