Изобретение относитс к машиностроению .The invention relates to mechanical engineering.

Цель изобретени - снижение неравномерности распределени нагрузки по сателлитам путем увеличени податливости между венцами сателлитов.The purpose of the invention is to reduce the uneven distribution of the load on the satellites by increasing the compliance between the crowns of the satellites.

На фиг. 1 представлен предлагае-- мый двухвенцовьш сателлит; на фиг.2- сечение А-А на фиг, 1,FIG. 1 presents the proposed two-satellite satellite; FIG. 2 is a section A-A in FIG. 1,

Двухвенцовый сателлит содержит зубчатый венец 1, выполненный заодно со ступицей 2, второй зубчатый венец 3 установлен на ступице 2 свободноDvuhventsovy satellite contains a gear rim 1, made integral with the hub 2, the second gear 3 is mounted on the hub 2 freely

момента в соответствии с величиной отклонени их зубьев в окружном направлении от номинала. Различие в на- груженности сателлитов зависит от величины угловой жесткости, св зывающей зубчатые венцы 1 и 3,torque in accordance with the magnitude of the deviation of their teeth in the circumferential direction from the nominal. The difference in the satellite load depends on the magnitude of the angular stiffness connecting the gear rims 1 and 3,

Выбором конфигурации лысок 4 и геометрических параметров клинообразных сухарей 6 и нажимных дисков 7 можно получить при большом взаимном смещении венцов 1 и 3 (до 30) сравнительно небольшие деформации тарельчатых пружин 8 и 9, т.е. при конечBy choosing the configuration of bald heads 4 and the geometrical parameters of wedge-shaped crackers 6 and pressure discs 7, with a large mutual displacement of the crowns 1 and 3 (up to 30), relatively small deformations of the disc springs 8 and 9, i.e. at the end

(с возможностью вращени ). На послед- 5 ной жесткости последних можно полу- ней равномерно по окружности выполнены лыски 4, а второй зубчатый венец 3 со стороны внутреннего диаметра имеет радиальные пазы 5 по числу лысок 4, ff которых установлены клинооб-20 разные сухари 6, контактирующие с нажимными дисками 7. Последние взаимодействуют с тарельчатыми пружинами 8 и 9, размещенными на ступице 2 по обе стороны от зубчатого венца 3.(with the possibility of rotation). On the last 5 rigidity of the latter, flats 4 are made evenly around the circumference, and the second gear crown 3 has radial grooves 5 on the side of the inner diameter, according to the number of bald heads 4, ff of which wedge-20 different crackers 6 are in contact with pressure discs 7. The latter interact with cup springs 8 and 9, placed on the hub 2 on either side of the ring gear 3.

Выравнивание нагрузки по сателлитам осуществл етс следующим образом.The equalization of the load on the satellites is carried out as follows.

При приложении вращающего момента, например, на зубчатый венец 1 он будет проворачиватьс относительно второго зубчатого венца 3, удерживаемого моментом сопротивлени . При этом происходит перемещение в пазах 5 клинообразных сухарей 6, которые с помощью нажимных дисков 7 сжимают. тарельчатые пружины 8 и 9. Возникающие при этом силы трени делают возможным передачу вращающего момента с зубчатого венца 1 на венец 3.When a torque is applied, for example, on the ring gear 1, it will turn relative to the second ring gear 3 held by the moment of resistance. When this occurs, the movement in the slots 5 wedge-shaped crackers 6, which with the help of pressure plates 7 are compressed. Belleville springs 8 and 9. The resulting frictional forces make it possible to transfer torque from gear ring 1 to ring 3.
