Double stage planetary gear 
for gas turbine generators

Sauter Bachmann manufactures and installs a double-stage planetary gear with power splitting in the range of approx. 2.5 MW output for a well-known European manufacturer of gas turbine generators. The input speed at the torsion shaft is 26,000 revolutions per minute and on the output side to the generator either 1500 (50Hz) or 1800 (60Hz) revolutions per minute. The Flex-Pin system is used for the bearings of each planet to ensure optimum power transmission from the many planet wheels to the gear rim and the sun wheel. The operation and the required reliability place extreme demands both on the production and on the assembly of the corresponding components.
