An electric steering gear system

Abstract

The invention discloses an electric steering gear system, comprising: a rudder cabin; a circuit board located on the upper side of the rudder cabin; a linkage steering gear assembly, including a linkage motor, a linkage reducer and a first gear located in the rudder cabin. Potentiometer and linkage rudder; differential steering gear assembly, including differential motor, differential reducer, second potentiometer and differential rudder located in the rudder cabin; wherein, the linkage reducer is arranged on the circuit board in parallel Below, the differential reducer is parallel to the linkage reducer, the direction of the output shaft of the differential motor is parallel to the differential reducer and the differential motor is located below the differential reducer, the direction of the output shaft of the linkage motor is perpendicular to the linkage reducer and the differential The speed reducer has a curved surface that fits closely with the linked motor. As a result, the cross-staggered distribution of the linkage steering gear assembly and the differential steering gear assembly makes the volume of the electric steering gear system smaller. On the premise of ensuring the precise and stable operation of the electric steering gear system, the application range of the electric steering gear system is wider. wide, saving costs.

Description

technical field [0001] The invention relates to the technical field of aircraft stabilization and control, in particular to an electric steering gear system. Background technique [0002] The electric steering gear is the direction control actuator of aircraft such as missiles, rockets, and drones. The aircraft realizes its own pitch, yaw, and roll by controlling the electric steering gear, so as to achieve the purpose of flying according to the predetermined trajectory and heading. The steering gear receives the steering command issued by the flight control system or the missile-borne computer, drives the deflection of the rudder surface in real time, and changes the aerodynamic moment acting on the aircraft, so as to achieve the purpose of controlling the heading and attitude of the aircraft. Depending on the purpose of the aircraft, there are different requirements for the performance indicators of the steering gear. Usually, the performance requirements of the steering ...
