Description
Drehvorrichtung an Speisevorrichtungen von Warmpilgerschrittwalzwerken Das Patent 856 zag betrifft eine Drehvorrichtung an Speisevorrichtungen von Warmpilgerschrittwalzwerken mit einem drehbaren Sperrklinkenhalter, bei der dieser von einem Motor konstanter Drehzahl über ein stufenlos regelbares, vorzugsweise ölhydraulisches Getriebe angetrieben ist. Dabei erfolgt die Regelung der Umlaufgeschwindigkeit des Sperrklinkenhalters durch Schwenken _ des ölhydraulischen Getriebes.Rotating device on feed devices of hot pilgrim step rolling mills The patent 856 zag relates to a rotating device on feed devices of hot pilgrim step rolling mills with a rotatable pawl holder, in which this is more constant by a motor Speed driven by an infinitely variable, preferably oil-hydraulic gear is. The speed of rotation of the pawl holder is regulated by swiveling the oil-hydraulic gear.
Fast alle Pilgerwalzwerke haben während des Anpilgerns eine etwas höhere Drehzahl, was darauf zurückzuführen ist, daB beim Anpilgern eine geringere Verformungsarbeit geleistet und der Walzenzugmotor entsprechend geringer belastet wird als während des eigentlichen Pilgerns. .Almost all pilgrim rolling mills have something during the pilgrimage higher speed, which can be attributed to the fact that a lower speed is used on pilgrims Deformation work done and the compactor motor is correspondingly less stressed is considered during the actual pilgrimage. .
Bei der Drehbewegung, die der Steuermann während des Anpilgerns dem Sperrklinkenhalter zu erteilen hat, hat er also nicht nur die durch den kürzeren Vorholweg geschaffenen. Verhältnisse zu berücksichtigen, sondern gleichzeitig auch die Drehzahländerungen des Walzenzugmotors auszugleichen. Um ihn von einer Berücksichtigung dieser Drehzahländerung zu entlasten und um die dadurch möglichen Bedienungsfehler auszuschalten, wird erfindungsgemäß vorgeschlagen, die Primärpumpe des ölhydraulischen Getriebes nicht durch einen gesonderten Motor mit konstanter Drehzahl anzutreiben, sondern den Antrieb vom Walzenzugmotor abzuleiten. Damit wird erreicht, daß die Menge des von der Primärpumpe geförderten Öls der Drehzahl der Walzen stets verhältnisgleich ist.During the turning movement that the helmsman makes during the pilgrimage to the So he not only has to give the pawl holder through the shorter one Created in advance. To consider circumstances, but also at the same time to compensate for the changes in the speed of the roller tractor motor. To get him out of consideration to relieve this speed change and to avoid the possible operating errors to turn off is proposed according to the invention, the primary pump of the oil-hydraulic transmission not by a separate motor with constant To drive the speed, but to derive the drive from the single drum roller motor. So that will achieved that the amount of oil delivered by the primary pump corresponds to the speed of the Rolling is always proportional.
