PLANETARY GEAR Russian patent published in 2022 - IPC F16H37/12 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering. The planetary gear contains at least two sequentially arranged planetary wheels, the bearing supports of which are located on the eccentrics of at least one eccentric shaft. The shaft eccentrics are shifted relative to each other in phase by equal angles. Each planetary gear has a main internal gear, and all the internal gears of the planetary gears are engaged with one external gear. Each planetary wheel is equipped with one preliminary planetary stage, for which purpose an additional internal gear profile is made on each planetary wheel, displaced relative to the main one and engaged with a planet gear mounted on a free carrier. The satellite is engaged with the gear on the input shaft of the mechanism, and each planetary wheel is mounted on bearings on the eccentric section of the free carrier, and the eccentric sections on the carriers of the planetary wheels are shifted in phase relative to each other by equal angles.

EFFECT: increase in the gear ratio of the planetary mechanism is provided while maintaining small weight and size characteristics.
