FIELD: machine building.
SUBSTANCE: invention relates to a planetary gearbox. Planetary gearbox with internal arrangement of a brake coupling contains the same number of braking and planetary gears. Planetary gears are fixed on a shaft which can rotate relative to two parallel axes. Brake gears can rotate around their proper axes and brake with the help of a brake coupling. Sun gear is fixed on an input shaft, while an output shaft is connected to a carrier. Brake gears are circular with teeth on the inner surface and are supported by bearings on the gearbox body. Brake coupling interacts with the internal surface of the cylindrical parts of the braking gears.
EFFECT: there is ensured a possibility to use a gearbox body for support of braking gears.
