Definitions
- the invention relates to a roll stand with a pair, roller bearings on two sides, on which, between the Bearing toothed drums are seated or their gearing circumference has and on their ends, outside of the bearings rolling disks can be applied, the one of the toothed drums with a a parallel drive axle seated, drive pinion and the another combs with a loosely mounted intermediate pinion, and drive pinion and also intermesh pinion.
- Roll stands of this type have the advantage of being light Accessibility of the rollers, their support shafts, adjusting devices and the rest of the rolling fittings.
- the closed one The toothed drive of the roller support shafts only allows use of rollers or roller disks with a relatively small diameter. This has the consequence that there are only slight rolling forces have the rolling stock applied, which in turn only one allow small width of the rolling stock.
- the bearing of the roller shafts takes place, also because of the small roller diameter, throughout in thin-walled, heavy-duty plain bearings.
- the rollers or the rolling disks are often made of hard metal or others Hard materials are manufactured for a longer service life and dimensional stability to achieve.
- the invention is based on the object of this rolling mill designs improve that such an influence is made possible.
- This task is solved in that the one support member, which is arranged on the roll stand, piston-cylinder unit that can be influenced by an inductive displacement sensor, and the other support member out, against each other, between arranged the rolling stand and the lifting arm, against each other adjustable wedge arm exist.
- a deflection of the roller shafts, which depend on the respective arising Rolling force can be compensated with the help of this device.
- roller support shafts 1 and 2 in the flange approaches 4a and 5a U-shaped lever arms 4 and 5 mounted and carry between the bearings toothed drums 6 and 7.
- the toothed drum 6 meshes with the on the axially parallel drive shaft 8 seated pinion 9, while the toothed drum 7 seated on the roller support shaft 2 combs with a loose intermediate pinion 10.
- the drive sprocket 9 and the intermediate pinion 10 in turn also comb together.
- the two lever arms 4 and 5 are, cf. Fig. 3 each around the Longitudinal axis of the drive shaft 8 or the loose axis of rotation 11 of the Intermediate pinion 10 in bearings 12 and 13 in the housing 3 of the roll stand stored.
- the lever arm 4 is against one with the housing 3 of the roll stand connected piston-cylinder unit 14 supported, while the lever arm 5 on one, here two Sliding wedges existing wedge position 15 is present.
- Between both free ends of the lever arms 4, 5 is elastic Link 4 a spring 16 arranged.
- the roller shafts 1, 2 with the Rolling disks 17, 18 bearing lever arms 4, 5 can, if necessary. with distance measurement and an inductive displacement sensor given predetermined distances and thus a predetermined distance of the two rolling disks 17, 18 are effected.
- an appropriate Position and force control of the piston-cylinder unit 14 can be any desired stiffness of the Adjust mill stand; quick and precise corrections are also possible the distance, i.e. of the roll gap between the rolling disks 17 to 18 possible.

Claims (1)
- Walzgerüst mit einem Paar, zweiseitig gelagerter Walzentragwellen (1, 2), auf denen, zwischen den Lagern jeweils Zahntrommeln (6, 7) sitzen, und auf deren Enden außerhalb der Lager Walzscheiben (17, 18) aufbringbar sind, wobei die eine der Zahntrommeln (6) mit einem, auf einer parallelen Antriebsachse (8) sitzenden Antriebsritzel (9) und die andere mit einem, lose gelagerten Zwischenritzel (10) kämmt und Antriebsritzel (9) und Zwischenritzel (10) ebenfalls miteinander kämmen, bei dem die Walzentragwellen (1, 2) jeweils im freien Ende einer einarmigen, um die Längsachse des Antriebsritzels (9) schwenkbaren Hebelschwinge (4, 5) lagern, wobei die Hebelschwingen (4, 5) durch einstell- und festlegbare Stützglieder (14; 15) gegen das Walzgerüst, und ihre freien Enden über ein elastisches Glied (16) gegeneinander abgestützt sind,
dadurch gekennzeichnet, daß das eine Stützglied aus einem, am Walzgerüst angeordneten, durch einen induktiven Weggeber beeinflußbaren Kolben-Zylinder-Aggregat (14), und das andere Stützglied aus, gegeneinander verschiebbaren, zwischen dem Walzgerüst (3) und der Hebelschwinge (4 bzw. 5) angeordneten Keilpaaren bestehen.
