Problems solved by technology

[0003] The existing variable center of mass adjustment electromechanical actuator has a cumbersome and redundant structure, occupies a large volume, and has many transmission links at the same time, which greatly reduces the stiffness and transmission efficiency of the entire system
On the other hand, the variable center of mass adjustment mechanism is not suitable for working under load. Once an excessive load occurs, it will cause a radial load on the ball screw pair in the system, which will greatly cause the screw to be stuck or even damaged, reducing the system reliability

Abstract

The invention belongs to the field of actuators and specifically discloses a moving mass center adjusting electromechanical actuator which comprises a servo battery, a control driver, a front baffle plate, guide rails, a guiding support structure, a servo motor, a ball screw pair and a rear baffle plate, wherein the front baffle plate and the rear baffle plate are respectively fixed on two ends of two guide rails and the ball screw pair; the ball screw pair is positioned between the two guide rails, and a bottom part of the servo motor can slide on the guiding support structure in a reciprocating manner along the guide rails; two sides of the servo motor are respectively provided with the control driver and the servo battery; the servo motor, the control driver, the servo battery and the guiding support structure form a mass block which can move along the guide rails in a reciprocating manner. According to the electromechanical actuator, the mass center of the whole electromechanical actuator can be changed via control of reciprocating movement of the mass block.

Description

technical field [0001] The invention belongs to the field of actuators, in particular to an electromechanical actuator for variable center of mass adjustment. Background technique [0002] Electromechanical actuators are important flight actuators used in aerospace vehicles. With the rapid development of electromechanical servo systems, in view of the natural advantages of electromechanical servo systems, the development prospects of electromechanical servo systems will be even broader in the future. [0003] The existing variable center of mass adjustment electromechanical actuator has a cumbersome and redundant structure, occupies a large volume, and has many transmission links, which greatly reduces the stiffness and transmission efficiency of the entire system. On the other hand, the variable center of mass adjustment mechanism is not suitable for working under load. Once an excessive load occurs, it will cause a radial load on the ball screw pair in the system, which wi...
