Abstract
A transmission for a drive assembly for driving a working machine at a variable speed of rotation having: a first planet gear set to which a first drive unit can be coupled and a second planet gear set which the working machine can be coupled. The first planet gear set and the second planet gear set each having planet gears which are arranged on at least two common planet shafts which are mounted in a planet carrier. The planet carrier is rotatably mounted in a transmission housing and can be driven by a second drive unit. A torque on the planet carrier can be braced against the transmission housing via a brake or locking mechanism or clutch.

A transmission for a drive arrangement of a machine configured to drive the machine with a variably adjustable rotational speed, comprising:
- a first planetary gear set to which a first drive unit can be coupled;
- a second planetary gear set, to which the machine can be coupled;
- a planet carrier rotatably mounted in a transmission housing and driveable by a second drive unit;
- wherein the first planetary gear set and the second planetary gear set each comprise respective planet gears arranged on at least two common planet shafts, which are mounted in the planet carrier;
- and
- at least one of one brake, a locking device, and a coupling via which a torque on the planet carrier configured to be directly braced against the transmission housing and accordingly is switched between the planet carrier and the transmission housing.
A drive arrangement of a machine to be driven with variably adjustable rotational speed, comprising:
- a transmission comprising:
- a first planetary gear set to which a first drive unit can be coupled;
- a second planetary gear set, to which the machine can be coupled;
- a planet carrier rotatably mounted in a transmission housing and driveable by a second drive unit;
- wherein the first planetary gear set and the second planetary gear set each comprise respective planet gears arranged on at least two common planet shafts, which are mounted in the planet carrier;
- and
- at least one of one brake, a locking device, and a coupling via which a torque on the planet carrier can be directly braced against the transmission housing and accordingly is switched between the planet carrier and the transmission housing having a first drive unit coupled to the first planetary gear set of the transmission;
- a machine coupled to the second planetary gear set of the transmission;
- the second drive unit coupled to the planet carrier of the transmission whose rotational speed can be superimposed on a rotational speed that is dependent on the rotational speed of the first drive unit,
- wherein the first drive unit and/or the second drive unit can be driven with variably adjustable rotational speed.
A method for operating a drive arrangement having a transmission including a first planetary gear set to which a first drive unit can be coupled;
- a second planetary gear set, to which the machine can be coupled;
- a planet carrier rotatably mounted in a transmission housing and driveable by a second drive unit;
- wherein the first planetary gear set and the second planetary gear set each comprise respective planet gears arranged on at least two common planet shafts, which are mounted in the planet carrier;
- and at least one of one brake, a locking device, and a coupling via which a torque on the planet carrier can be directly braced against the transmission housing and accordingly is switched between the planet carrier and the transmission housing having a first drive unit coupled to the first planetary gear set of the transmission;
- a machine coupled to the second planetary gear set of the transmission;
- the second drive unit coupled to the planet carrier of the transmission whose rotational speed can be superimposed on a rotational speed that is dependent on the rotational speed of the first drive unit, wherein the first drive unit and/or the second drive unit can be driven with variably adjustable rotational speed, comprising:
- exclusively effecting a drive of the drive arrangement via the first drive unit;
- and
- bracing a torque on the planet carrier against the transmission housing via the at least one of the one respective brake, the locking device, and the coupling.
