Abstract

The invention belongs to the technical field of interior structure design of electromechanical actuators, and particularly relates to a slide slot type guide tooth limiting and guide device of an electromechanical actuator. A base body of a guide tooth is fixedly mounted in a groove in the axial direction in one side of an inner hole of an actuator housing; an actuating rod is positioned inside the actuator housing, and one end of the actuating rod gets out of the actuator housing; a nut sleeves the outer wall of a lead screw, and is connected with the other end of the actuating rod; a guide tooth slot base body is pressed into the groove in the actuating rod and is fixed; a supporting ring is mounted on the actuating rod and is in contact with the actuator housing; and the guide tooth isin engaged connection with the guide tooth slot. The slide slot type guide tooth limiting and guide device changes surface-surface friction into line-line friction or line-surface friction, can acheive the effect as rolling friction within a short-time working occasion, and greatly reduces friction force and efficiency loss.

Description

technical field [0001] The invention belongs to the technical field of internal structure design of electromechanical actuators, and in particular relates to a chute-type guide tooth limit guide device for electromechanical actuators. Background technique [0002] In the aerospace vehicle control system, the electromechanical servo system is an important executive system, which plays a role in controlling the flight attitude of the aircraft. In recent years, due to the advantages of compact structure, high specific power and convenient maintenance, the electromechanical servo system has developed rapidly and has many successful applications. [0003] As an important part of the electromechanical servo system, the electromechanical actuator is the actuator of the electromechanical servo system. During work, the rotational motion of the motor is converted into a linear output through the action of the screw pair. The conversion process also needs to limit the movement of the a...
