Abstract (en)
[origin: EP2161416A2] The rotor turning device (5) has a rotor (1) with a drive pinion (3), on which the rotor is driven with the rotor turning device. A hydraulically driven outer gear wheel motor (6) is provided with two gear wheels (7,8) intermeshing in the external contact and a housing (9) surrounding the gear wheels. The housing has a recess (13), with which one of the gear wheels is exposed such, that the exposed gear wheel is engaged with the rotor turning device coupled with the drive pinion. The drive pinion is driven by the exposed gear wheel. An independent claim is included for a steam turbine with a rotor.
