Abstract
A generator drive for matching the rotation speed of a gas turbine to an electricity generator, The drive from the gas turbine is introduced by a sun wheel into planet gears of a first epicyclic gear stage and is driven via further planet gears of a second epicylic gear stage, which are each arranged on a common planet gear shaft with the planet gears of the first gear stage, by an annular gear to the generator. The planet gear shafts are mounted in bushes which can each be inserted complete with the planet gears into openings on a supporting wall of the drive. With respect to their distances from the bearing, the planet gears are arranged on the planet gear shaft such that the moments which result from the circumferential forces about the bearing essentially cancel one another out.
