ELECTRIC DRIVE WITH PLANETARY REDUCER FOR MECHANICAL SYSTEMS OF SPACE APPARATUS Russian patent published in 2019 - IPC F16H1/46 H02K7/10 

FIELD: machine building.

SUBSTANCE: invention relates to the machine building. Electric drive with a planetary gearbox for mechanical systems of spacecrafts contains an electric motor, a reducer, including a housing, a high-speed shaft connected to the electric motor by means of a front stage, a high-speed, intermediate and low-speed planetary rows, low-speed shaft, made as a unit with a low-speed carrier and mounted on two ball bearings, high-speed carrier, made with support from the side of the electric motor, sun gear connecting the internal toothed rim of the high-speed carrier with the intermediate carrier carriers. Sun gear connecting the internal gear rim of a high-speed carrier with satellites of the intermediate carrier is made with central sections of the ends with spherical holes in which balls are installed. One well is made with a clearance for the ball along the side spherical surface, and its base is made in the form of a plane orthogonal to the axis of the said sun gear, on the other side of the specified ball, a similar hole is made in the body of the adjusting bolt with a lock nut installed in the body of the axis of the intermediate carrier. Ball of the other hole on the opposite side of the sun gear is made with a cup spring, the support of which is made in the body of a high-speed carrier.

EFFECT: improved efficiency and reliability of the drive.
