Eisenbeiss singledrive gears stand out through their compact horizontal or vertical designs. The high power density of the double helical gearing enables the transmission of up to 6 MW with pinion distances of only 400 mm in parts. The use of opendie forging shafts means that no shaft/hub collar connection is required in the gear unit.
LIFTING MECHANISM WITH TWO DRIVES Eisenbeiss uses superimposed planetary gear systems to help realise twomotor drives for full or half lifting speed. Thanks to this drive redundancy the lifting gear remains operational even if one motor fails.
In a multimotor drive, the separate operating members of a machine are driven by their own motors and transmission systems. Such a drive makes possible machines of compact design and the use of automatic control. Multimotor drive is used in complicated machine tools, rolling mills, and hoisting and transport machines.
On the other hand, there are excited vibrations in the rolling stands determined by the damage that exists in some parts of the rolling mill machine. In this context, there are vertical vibrations [3] from the roll stand (116 Hz.), torsion chatter of the main drive (520 Hz.), interspaces chatter or .
Mar 31, 2015· ThyssenKrupp Steel Europe spent a quarter of a million euros on renovating its hotstrip rolling mill in Duisburg. The animation shows how it all works.
Throughout the years ERM acquired and installed new plant in order to keep its good position in the industry. For some mills such as the main hot mill the electric drive motors and controls were extensively modernised and the runout tables extended to allow the rolling of heavier slabs to bigger pieceweights.

Based on vibration problems of a six roller cold rolling mill, hydraulicmachinery coupling vibration system dynamic model of the 2180mm 4stand tandem cold rolling mills was built integrated the software of MATLAB and ADAMS and simulated. The simulation result was consistent with that of the field test data revealed by rolling mill vibration.
Mill Vibration Phenomena during Cold Rolling. All machines vibrate during operation. However, only a few of these vibrations cause problems to the product or the machine itself. Typically, the most damaging vibrations involve a natural resonance of the machine which significantly increases the .
