Abstract

The invention concerns a gear unit for driving the rolls of a roll train with a number of consecutively arranged roll stands. This gear unit has planetary gear sets at at least one output shaft, which are located one behind the other at short distances. Due to a crosshead provided in accordance with the invention, the output shaft of each planetary gear set is relieved of bearing forces and the torques of the gears, such that it can have a small diameter, which in turn permits a building up of the planetary gear set, such that the operating torque and the operating r.p.m.'s of the planetary gear sets can be considerably higher than in the familiar construction types.
