ELECTROMECHANICAL ROTARY DRIVE AND THE METHOD OF MANUFACTURING OF SUCH A DRIVE Russian patent published in 2017 - IPC B64C27/615 H02K7/00 

FIELD: electricity.

SUBSTANCE: electromechanical rotary drive comprises a housing having a first end extending to the second end through an intermediate portion defining a longitudinal axis and an inner cavity. The motor is installed in the inner cavity. The electric motor comprises a shaft having a first end of the shaft and a second end of the shaft. The drive element is located inside the body along the longitudinal axis. The drive element comprises an input shaft operatively connected to the first end of the shaft and an output shaft. The output shaft of the drive element is connected to the output shaft element. The bearing assembly serves as a support for either the output shaft element or the first end of the shaft. Inside the housing, a preload element is provided for applying a compressive thrust force to at least one mentioned bearing, drive element and electric motor.

EFFECT: ability to adjust the pitch of the blade of the rotorcraft in all modes of operation.
