CPU gear units are specially designed The design of the two-stage planetary gear unit guarantees optimum power transmission in the 1'000 to 10'000 kW range. The gearbox comprises two co-axial planetary stages arranged one behind the other. Both stages are spur-toothed planetary gears with fixed ring gear and rotating planet carrier (except CPU-9 ... CPU-17: first stage with fixed planet carrier and rotating ring gear). All bearings are slide bearings. Both stages are provided with its own housing. The internal toothed coupling guarantees reaction-free power transmission from the...

has a limited axial displacement and therefore requires an axial bearing on either the motor or gearbox side. The easy disassembly of the coupling spool piece allows the first planetary stage to be displaced towards the motor side for maintenance purposes, allowing the main motor to remain in place during maintenance work. This coupling also provides electrical insulation between the motor and the gearbox. Auxiliary drive The auxiliary drive is intended to slowly turn the mill for maintenance works or for the even cooling down of the mill. The auxiliary drive is equipped with a planetary...

Annulus (ring gear) Sun pinion Slide bearing Planet Internal coupling MAAG Gear toothed coupling ZEXF MAAG Gear toothed coupling ZCF Function Power input is achieved by the sun pinion of the first stage. In the first and second stage three planet wheels in mesh with the sun pinions transmit the power to the rotating planet carriers. The rotating planet carrier from the first stage is connected by a toothed coupling with the sun pinion of the second stage. The planet carrier from the second stage forms the output flange of the gearbox. The internal toothed coupling guarantees reaction-free...
