PLANETARY GEAR WITH PRESTAGE Russian patent published in 2022 - IPC F16H1/28 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering. Planetary gear with a preliminary stage contains a housing with input and output shafts, an internal planetary gear mounted on bearings on an eccentric section of a free carrier. The planetary wheel has an internal gear ring, which it interacts with the preliminary stage and an outer ring, which is engaged with the inner ring of the additional central wheel. The planetary wheel is equipped with a mechanism for transmitting rotation between parallel shafts, the axes of which have a relative movement. The preliminary stage is represented by a central gear on the input shaft of the transmission, with which the satellite is engaged, mounted with the possibility of rotation on the free carrier. The planetary wheel is made with two identical inner rims, the satellite is made in the form of a satellite block of three gears rigidly connected to each other, while the larger wheel, located in the middle of the block, engages with the central gear on the input shaft, and the smaller side wheels are in engagement with the inner rims of the planetary wheel.

EFFECT: invention provides an increase in the gear ratio without changing the dimensions of the transmission.
