ENGINE TURNING AND STARTING DEVICE OF GAS TURBINE PLANT Russian patent published in 2016 - IPC F02C7/32 F01D25/34 

FIELD: machine building.

SUBSTANCE: engine turning and starting device of gas turbine plant comprises drive motor, reduction gear and overrunning clutch compressor rotor. Reduction gear comprises gearbox with three pairs of inter-engaged gears and simple three-link planetary mechanism. At the input shaft gearbox two gears are freely installed between them is fixed gear rim with three position clutch. Gear rim with three position clutch tubular output shaft is fixed on the front end, located between second and third rows of gears. At the second rim tubular output shaft there is a double two-position clutch, nearby it are rims Sun gear drive shaft and tubular shaft drive carrier of planetary gear. Satellites located on axles, engaged with Sun gear, as well as with epicyclic wheel, which is fixed on the output tubular shaft with rim next to it there is a rim of the output shaft of carrier. Two-position clutch is installed on the rim of the wall of the gearbox casing near the rim of the tubular shaft epicyclic wheel. At the output of the second three-link planetary mechanism, and the gear box is misaligned. Parallel to the inlet shaft there is a secondary shaft with freely mounted unit of two gears and tubular output shaft with freely mounted gears with secured on secondary shaft three rims. First rim and three position clutch is fixed on the end face between housing and a unit of gears, second toothed rim is fixed between the rims of the tubular gearbox output shaft and tubular input shaft of carrier first, third gear rim is located between the rims of the tubular output shaft of the first planetary gear and tubular input shaft of carrier second planetary mechanism. Cage with five-way rim is freely installed at the output of the secondary shaft and the input shaft drive Sun gear of the second planetary mechanism. Reduction gear output shaft is fixed on the carrier of the second planetary mechanism.

EFFECT: invention allows increasing the number and range of gear ratio turning gear and starting device.
