A highly integrated electromechanical actuator with integrated design

Abstract

The invention discloses a highly integrated electromechanical actuator. One end of a screw actuating rod assembly is provided with a front end support lug connection assembly, and the other end of the screw actuating rod assembly is provided with a long nut rotor assembly for cooperation. When the long nut rotor assembly performs the fixed-axis rotation, the screw actuating rod assembly makes reciprocating rectilinear movement. The exterior of the long nut rotor assembly is connected with a servo motor stator assembly through a rotor support fixing assembly. An angular velocity sensor assembly is installed on the long nut rotor assembly, and is used for detecting the angular velocity of a motor rotor. A linear displacement sensor assembly is installed on the screw actuating rod assembly and an actuating rod support fixing assembly which is used for providing a support and fixing effect for the installation of the screw actuating rod assembly, and is used for detecting the displacement information of an actuating rod. A rear end support lug connection assembly is connected with the servo motor stator assembly, and is used for bearing an axial tensioning and pressing load, and preventing the electromechanical actuator from rotating in the peripheral direction. The front end support lug connection assembly and the rear end support lug connection assembly are respectively connected with an external device mechanical interface.
