The Srfindmi ^ "relates to a universal rolling mill, in particular Streck-Tedo2ierv & l2verk, with several hierarchies arranged is arranged. above the Saliber-Citte, a ISIT to, one side of the open C-foraigen Gerüatbett, in which the frameworks are laterally insertable., and ¹ old za. the Valzenachsen aligned drive shafts which are stored in the Gerütitbett and oit the Walzenaehsen detachable are, whereby the old, the not vertically arranged horizontal disks connectable Intriebswellezi are connected via bevel gears sit intermediate shafts.

Such universal mill have prevailed in recent times, in particular ia a view to da3 the-replaceable when changing the Valzprogr & QB3 or ¥ alzenver3chlel3 frameworks can be designed to be relatively small, since the Zegelradgetriebe outside of the framework in dea Gei-Üstbett anfjeordnet are, and s ± & itself consequently, it can be easily and quickly installed and removed. In addition, such scaffolds are relatively inexpensive, so that the storage of scaffolding sets is profitable for various rolling programs.

In a known universal rolling mill of the type mentioned, the input shaft for the respective stand is connected to the drive shaft of the vertical roller disk via a frontal stump. On the input shaft there is also a bevel gear, which meshes with the bevel gears on the two intermediate shafts of the two other Valsenach disc drives and drives the two remaining roller disks via the intermediate shafts, the bevel gear units arranged in the frame bed and the drive shafts. In such a drive scheme, the two intermediate shafts extend obliquely upwards and downwards through the scaffolding bed from the input shaft, whereby they form an angle with one another which is open towards the open side of the scaffolding bed. Since the two intermediate shafts in the scaffolding bed lie in the same vertical plane as the scaffolding to be used, the opening angle between the two intermediate shafts or the distance of the intersection of the axes of the two intermediate shafts from the installation location of the respective scaffolding must be so large that there is enough space for the scaffolding to be pushed in remains free. Since the position of the drive shafts is fixed by the predetermined position of the roller disks, the bevel gears provided between the drive shafts and the intermediate shafts, which are arranged somewhat in front of the intersection of the drive shafts with the intermediate shafts, must be arranged at a considerable distance of ³ mm center, that is that the dimensions of the frame bed in which the shafts and gears are mounted must be very large both in height and in width. This fact has a disadvantage in that there is not always enough tree available at the honing areas and the relatively wide construction requires a lot of material.

The invention is based on the object of a universal rolling mill to make the type mentioned at the outset more compact.

Invention agooäS this object is achieved in that on the feachloaenen side of the scaffold bed a per se known comb roller is provided and that the intermediate shafts parallel to iSmt Airirlebawelle the vertical roller disc are arranged horizontally in the Gtrüatbatt and connected to the corresponding comb rollers.

iirisbssn dining also has the advantages of? themselves Due to the spur gears arranged on the input side, greater rotation ■ oaente let transfer.

Among other things, to relieve the spur gears of the Kannwalzenroihe located in the area of the drive shaft, the power input can be connected to that Kanawalzenwell © to which the drive shaft of the vertical roller disc is connected, so that a continuous shaft train is created from the Mntriebsvell © to the vertical roller disc and the Kamnvälzenzeile with which the coaent to be transferred to the vertical valve disk is not burdened.

Invention is illustrated in the drawing, for example Unl is described below in general with reference to the drawing.

The drawing shows a cross-section in a scholarly representation by means of a stretch reduction valve according to the invention.

As shown in the drawing, the stretching roller mill has a 3 C-shaped geriatric bed 2 open to the right, in which the consecutively arranged formers 4 can be inserted laterally. The individual framework consists of three, inter alia, glass disks 6, B _t 10 b * v, arranged offset from one another by 120 °. 6 ", 3 ', UO', which form the caliber 12. The valaenaxi order is chosen so that one of the roller disks alternates from stand to stand in a vertical position 3cre'ed under b * v. Above the caliberaitte In the section shown in the drawing, the vertical roller disk 6 is

Arranged over 12 caliber.

The drive devices that are not shown in the drawing can be used both as individual drives and as group drives be trained. The input shafts 14 and 14 '' connected to the drive devices, of which the input shaft 14 is in the • The cutting plane is located, each drive a crested orphan row 18 or 18 ·, which is made up of seven vertically one above the other, ita engagement Put the stationary spur gears 22, 24, 26, 28, 30,> 2 and 34 together. Sis spur gears of the respective comb roller row are on the closed side of the C-shaped frame bed 2 arranged and allow a particularly favorable geometric arrangement of the shaft lines leading to the roller disks for the transmission of the torque.

From the uppermost spur gear 34 of the row of comb rollers 18, the torque forwarded to the obliquely to the open side of the stand bed 2 inclined roller disk 8, while the torque for the obliquely The roller disk 10 inclined to the comb roller row is removed from the lowermost spur gear 22. The drive of the vertically standing roller disc 6 takes place directly via the! «Drive shaft 14» which is coaxial to the drive shaft 36 of the roller disk 6 is located and via a coupling 38 is connectable with this. As a result, the Kasmvalzen series of a third of the total torque is relieved, de that on the input shaft Η seated spur gear 30 of the comb roller row 18 now only a third of the torque to the forehead above * » wheels 32 and 34 and the other third to those arranged below Spur gears 28, 26, 24 and 22 has to be transferred.

Ton the upper spur gear 34 or the lower spur gear 22 is the Torque via an intermediate shaft 40 or 42 and a downstream bevel gear 44 or 46 on the inclined orphan pulleys 8 and 10 transferred.

702344917.1170

The two intermediate shafts 40 and 42 are arranged horizontally and lie in one plane with the drive shaft * 6 of the vertical V & lzenscheibe 6. Both the two intermediate shafts 40 and 4.2 and 4ie bevel gears 44 and 46 are mounted in the C-shaped frame bed 2. The shafts 48 and pO of the drive side. When the device 4 is installed, bevel gears of the gears 44 and 46 are coaxial with the drive shaft * »56 and 53 of the obliquely arranged roller discs 3 and 10 and can be connected via clutches 52 and 54 not connect with this.

The three-component transmission for the following or preceding stand, which can be driven via the input shaft 1. ", is in principle the same as for the stand shown in the plane of the drawing. The torque is generated once from the input shaft 14 * directly via the drive shaft 36 ^{the vertical 'tfalzenscheiöe 6 1} located below the caliber 12 is transferred, while the drive of the inclined roller ^{disks S 1} and 10', which are arranged offset by 180 relative to the roller disks 8 and 10 of the stand shown in the plane of the drawing, also over from the comb roller row 18 * Outgoing intermediate shafts and bevel gears 44 'or 46' arranged offset relative to the plane of the drawing according to the geometrical conditions.

As can be seen from the drawing, the bevel gears 44 »44 ¹ or 46, 46 'can generally be arranged at a relatively short distance from the applicable scaffolding, so that the overall dimensions of the system can be kept relatively small and a compact construction can be achieved .
