FIELD: metallurgy. ^ SUBSTANCE: driver of rolling mill contains motors, high speed shaft mounted in body, low-speed shaft, mounted co-axial on bearing support and connected to forming roll, and also control gear in the form of gears, wheels of which are mounted on high speed and low-speed shafts, at that one low-speed shaft is passed through the second low-speed shaft freely, and bearing supports of shafts are located in body, gears are implemented as single-stage, through-going low-speed shaft is related directly to forming roll, and hollow low-speed shaft is related to other roll by means of gear with reduction ratio, equal to one. Furthermore, control gear can be implemented in the form of differential spur gear train, one central wheel of which is connected to through-going low-speed shaft and the second - with hollow. ^ EFFECT: increased load-carrying ability of driver and reduced its overall dimensions. ^ 2 cl, 2 dwg |
