Abstract

The invention provides a highly integrated electromechanical actuator comprising a direct drive motor, a ball screw and an LVDT (linear variable differential transformer) which are arranged in a main frame. The direct drive motor comprises a motor stator, a motor rotor and a rotary shaft which are connected sequentially, and the motor rotor and the rotary shaft are produced integrally. The ball screw comprises a round nut and a screw shaft, and the screw shaft is connected to the rotary shaft through the round nut. The LVDT comprises an LVDT fixing sleeve, an LVDT iron core, an LVDT shell and an LVDT extending rod. The LVDT shell is arranged in the screw shaft and is connected to a left end cover through the LVDT fixing sleeve, the LVDT extending rod is arranged in the LVDT shell and is connected to the screw shaft, and the LVDT iron core is arranged in the LVDT shell and is connected with the LVDT extending rod. The highly integrated electromechanical actuator has the advantages of simple structure, convenience for mounting, small size, light weight, strong bearing capacity, high moving accuracy and transmission efficiency, good anti-jamming performance and low cost.

Description

technical field [0001] The invention relates to an electromechanical actuator, in particular to a highly integrated electromechanical actuator with small volume, good anti-interference performance and high motion precision. Background technique [0002] There are two types of power-by-wire actuators: electromechanical actuators and electrohydrostatic actuators. The electromechanical actuators are powered by motors, and then go through the transmission parts to the actuators, and finally convert the rotary motion into linear reciprocating motion. The electric hydrostatic actuator needs the support of the hydraulic transmission device to convert the rotational motion of the motor into the linear output of the actuator. The speed response and motion accuracy are poor, and the oil is easy to leak and pollute the environment. [0003] In the past, the motor and the rotating shaft of the electromechanical actuator were separately installed, and the motor and the rotating shaft wer...
