CYCLOIDAL GEAR ELECTRIC DRIVE Russian patent published in 2020 - IPC F16H1/32 H02K7/116 

FIELD: machine building.

SUBSTANCE: invention relates to drives. Planetary-lantern electric drive includes housing, stator and rotor installed in shell rigidly connected with electric drive eccentric input shaft. Input shaft has two oppositely oriented eccentric cylindrical sections, on which satellites with external teeth are installed through bearing supports. Input shaft transmits cycloidal motion to satellites, which leads to rolling of pins by satellite outer teeth, these pins are laid in inter-tooth cavities of fixed housing. Difference in number of external teeth of satellites and number of pins per 1÷3 leads to rotation of satellites about its axis. Between the satellite and its associated outlet flange there is a cross-shaped coupling which detaches from the complex motion of the satellite only rotation around the axis and transmits it to the output flange. Outlet flanges are installed in the housing on bearing supports and tightened by bars, at that one of output flanges is rigidly connected with output shaft.

EFFECT: improved reliability of the electric drive, as well as reduced dimensions.
