FIELD: engines and pumps.
SUBSTANCE: invention relates to machine building, in particular, to devices transmitting rotation from power plant to planetary reduction gear satellite gears. The proposed device has a housing accommodating a jack shaft aligned by bearings and spacers relative to the housing surfaces of coupling with the planetary reduction gear, the jack shaft being furnished with working surfaces that, when meshed, transmit rotation from the power plant shaft to the planetary reduction gear satellite gears. The said jack shaft is aligned also by bearings and spacers relative to the housing surfaces of coupling with the power plant.
EFFECT: high reliability and accuracy of torque transmission from the power plant via the jack shaft to the planetary reduction gear.
