PLANETARY GAPLESS GEAR Russian patent published in 2019 - IPC F16H57/12 

FIELD: robotics.

SUBSTANCE: invention relates to multisatellite toothed planetary gears and can be used in robotics and other mechatronic systems. Planetary gapless gear contains sun gear (1), flexible fixed central wheel (2), satellites (3) are made with increased thickness of teeth and located by means of spherical rolling bearings (4) on flexible cantilever axes (5), and carrier (6). Flexible axis of each satellite (5) has two parallel flats perpendicular to the radial plane. Radial flexibilities of flexible fixed central wheel (2) and flexible axis of satellite (5) are higher than their circumferential compliance, which allows reducing elastic play of play at selection of gaps in engagement of wheels.

EFFECT: higher technological effectiveness of transmission.
