PLANETARY GEAR Russian patent published in 2018 - IPC F16H1/32 

FIELD: machine building.

SUBSTANCE: invention relates to gearing. Planetary gear contains a sun gear, satellites, bearings, axes of satellites on which two rows of satellites are located on both sides of the bearings, a carrier and a stationary central wheel. Sun gear and stationary central wheel have annular grooves in the middle part of their toothed rims, the width of the grooves corresponds to the width of the bearing, and the depth is equal to at least twice the difference in the radii of the outer bearing ring and the circumference of the tooth slot of the satellite. Carrier is made in the form of a thick disk with landing seats of cylindrical shape on its end part, and satellites – with a diameter of the tips of the teeth smaller than the diameter of the outer rings of bearings, which are seated in the carrier seats.

EFFECT: increase in the level of manufacturability and simplification of the design of planetary gear is provided.
