SERVO DRIVE WITH DRUM-ROLLER ACTUATOR Russian patent published in 2024 - IPC B64C13/50 B25J9/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, namely to the design of electric drives providing for movement of the actuator in space. Servo drive comprises power amplifiers, a drive unit, a transducer reduction gear and a position transducer. Drive unit comprises base, motor, flexible tape wound on drums. In contact with drums there are contact bearings fixed on balancers. Steering plane is fixed on axis installed in aircraft body. Balancers are connected to steering plane by means of rotary element stand, which is rigidly connected to steering plane. Steering plane position sensor is installed on the axle. On the shaft of the electric motor there is a gear which is mechanically connected to gears rotating in opposite directions. In order to change the direction of rotation of one gear, an additional unit of gears is installed to the gear shaft, as well as a damper required to smooth the negative effect of the reducer play taking into account external disturbances.

EFFECT: reduction of dimensions and increase of efficiency due to refusal to use the second electric motor, and, as a result, reduction of power part of the control unit.
