Steering gear system Swing type electric servo mechanism

Abstract

A yaw-type electric servo mechanism for a steering gear system, using a rare-earth motor as a driving source, after the torque is increased through a reduction box, it is transmitted to the output of the yaw system, which can drive the load to swing with a limited rotation angle, and the yaw system will swing The angle is fed back to the swing position signal of the control system through the potentiometer. The transmission scheme combining NGW planetary gearbox and ball screw is adopted, and four yaw-type servo mechanisms are evenly and symmetrically arranged on the end cover of the steering gear with an installation section diameter of 80-120mm. The servo system and drive circuit are placed in the gaps of the four yaw-type servo mechanisms, which saves space, facilitates system installation, and is conducive to the layout of the whole bomb, creating favorable conditions for the miniaturization of missiles. The compact structure layout is better than harmonic gear transmission The solution reduces the volume by 40% and the weight by 25%, and solves the problem of miniaturization and light weight of the steering gear. <pb pnum="1" />

Description

Steering gear system Yaw type electric servo mechanism technical field The invention relates to an electric servo mechanism of a steering gear system, in particular to a swing type electric servo mechanism of the steering gear system. Background technique In recent years, with the vigorous development of aerospace, aviation, weapons and other industries, various advanced precision-guided missiles have been miniaturized and lightweight, and the requirements for the overall performance of missiles are getting higher and higher. As an important part of missiles, steering gear The transmission system has become the focus of development and optimization. The transmission structure of the existing steering gear transmission system generally adopts the transmission scheme of the combination of harmonic gear and bevel gear. The steering gear transmission system of an advanced missile currently in service in my country adopts a combination of harmonic gear and bevel gear. The main...
