Greater Productivity through Maximum Torque Capacity – voestalpine Grobblech Successfully Puts Innovative Voith High-Performance Drive into Operation
The development of the new GearLink concept is the result of close collaboration between voestalpine Grobblech, BUMA engineering and Voith. Universal joints with a rotational diameter of 1300 mm are used in the voestalpine Grobblech rolling mill. The fully forged CHF 1300.8 universal joint shafts are all of varying length, which results in the shafts being offset on the roller side. This means that shafts of equal size can also be used on the roller side regardless of the roller diameter of 980 mm. The GearLink element (a curved-tooth coupling shaft) guarantees the connection between the offset shafts and the coupling sleeves. This reduces the load of bending moments on the roll journals to the greatest extent possible and allows the axial CVC (Continuous Variable Crown) displacement of the rollers. The coupling shaft also provides an axial emergency outlet in case of oblique fractures of the rollers.
voestalpine Grobblech uses materials of the highest quality to produce steel sheets which are used, for example, in the construction of pipelines.
