Linear electric steering engine for rudder angle control device

Abstract

The invention relates to a linear electric steering engine for a rudder angle control device. The linear electric steering engine comprises a motor assembly, a box body, an end cover, a telescopic thread sleeve, a limiting screw, a connecting rod, a mounting plate and a precision potentiometer, the motor assembly is composed of a screw rod and a torque motor, the telescopic thread sleeve is arranged on the screw rod in a sleeving manner, the telescopic thread sleeve is assembled in an inner cavity of the box body, the telescopic thread sleeve is in clearance fit with the box body through a linear bearing, an internal thread meshed with the screw rod is machined at one end of the telescopic thread sleeve, a U-shaped groove for limiting the movement of a limiting screw is formed in the outerdiameter of the same end, the limiting screw is assembled on the side wall of the box body, a through hole for assembling the connecting rod is machined in the other end of the telescopic thread sleeve, the mounting plate is fixedly mounted on the upper surface of the box body through the screw, one end of the connecting rod is connected with a pull rod extending out of the precision potentiometer, and the other end of the connecting rod is fixedly connected with the telescopic thread sleeve. The steering engine is high in steering efficiency, good in reliability and maintainability, flexiblein steering, capable of easily achieving multi-channel control, simple and compact in structure and light in weight.

Description

technical field [0001] The invention belongs to the technical field of electric steering gear, and in particular relates to a linear electric steering gear for a rudder angle control device. Background technique [0002] At present, the research and development of underwater devices has attracted more and more attention from various countries. The rudder angle control device is the executive mechanism of its control system, which is used to convert the command signal of the control system into the control force of the underwater device, which is one of the key points. For the part, it requires the rudder angle adjustment to be very effective and reliable, and the structure should be as simple as possible and occupy less space. The speed and effectiveness of rudder angle adjustment depend on the operational effectiveness of the electric steering gear. Its performance directly affects the performance of the entire control system. Based on the fact that the steering gear used i...

Problems solved by technology

The speed and effectiveness of rudder angle adjustment depend on the operational effectiveness of the electric steering gear. Its performance directly affects the performance of the entire control system. Based on the fact that the steering gear used in most rudder angle control devices is mostly pneumatic or hydraulic, this Although the design is effective, the overall structure is too complicated and the weight is relatively large. There are special requirements for machining accuracy, assembly adjustment and material selection. It is necessary to improve the existing structure, that is, to invent a linear rudder angle control device. Electric steering gear is very meaningful and necessary
