LINEAR ELECTRIC DRIVE Russian patent published in 2020 - IPC F16K31/04 F16H1/00 

FIELD: electrical equipment.

SUBSTANCE: linear electric drive relates to electromechanical linear actuators, which is a combined structure of an electric motor and a screw—nut eccentric transmission. Linear electric drive comprises electric motor and screw—nut eccentric transmission, in which input shaft is made with cams, on which screws are installed with possibility of rotation, interacting with screw thread of nut. Surfaces of screws and nut are made with additional mating toothed profiles. Electric motor is aggregated with screw—nut transmission, for this purpose its rotor is directly connected to input shaft of transmission, and transmission nut is installed with possibility of axial movement from outside on housing of electric motor by means of tooth profile on its inner surface, which forms splined connection with teeth made additionally on external surface of housing.

EFFECT: technical result is creation of electric drive, which reduces linear dimensions of drive at same stroke length.
