Abstract
In a transmission for driving the rolls of a rolling line having a number of rolling stands disposed one after another, a respective planetary transmission stage is provided at several output shaft (20) and forms the output rotational speed from a basic rotational speed and an additional rotational speed. The gear wheels (2,23) of the gear wheel transmission trains transmitting the basic and additional rotational speeds are mounted on stationary bearing bushes (3, 26) which project into the hub regions of the gear wheels (2, 23) and are secured in bores or on flange facings of the load-bearing walls (5, 6) of the transmission housing (1). Only one of the gear wheel transmision trains is disposed between the load-bearing walls of the transmision housing, while the other is disposed on the outside stands. This permits the transmission to be of lighter construction and allows greater gear ratios in the gear wheel transmission trains and a smaller distance between the output shafts (20).
