Abstract

The invention belongs to the technical field of an electromechanical actuator, and provides a modular parallel type electromechanical actuator having the advantage of compact structure, concise transmission and simple assembly debugging. The modular parallel type electromechanical actuator comprises a servo motor (1), a gear reducer (2), an electromagnetic lock (3), a ball screw assembly (4) and a bolt assembly (5). An output shaft of the servo motor (1) is connected with a small gear shaft of the gear reducer (2), a large gear shaft of the servo motor (1) is connected with an input shaft of the ball screw assembly (4), the servo motor (1) and the ball screw assembly are arranged in parallel, and the electromagnetic lock (3) is installed on a housing of the gear reducer (2). Functions between the various function modules are independent, interfaces are clear, and an electromechanical actuator having complete functions can be formed through simple combinations. The modular parallel type electromechanical actuator has the advantages of high universality between the modules, simple assembly, high production efficiency and convenient fault positioning, is suitable for batch production, and greatly improves maintainability and supportability of a system.

Description

technical field [0001] The invention belongs to the technical field of electromechanical actuators, and in particular relates to a modularized parallel electromechanical actuator. Background technique [0002] The electromechanical actuator is the actuator of the servo system. It is usually composed of a servo motor driving a servo transmission mechanism. The transmission mechanism is an important part of the electromechanical servo actuator. Electromechanical actuators have the advantages of frequent forward and reverse rotation, precise position control, high dynamic response, light weight and miniaturization, good maintenance performance, long storage period, and good process stability. [0003] There are various types of electromechanical actuators. According to the form of electromechanical actuator motion output, it can be divided into three types: rotary type, linear type and parallel type. The rotary electromechanical actuator refers to the motor-driven transmission...
