A flat integrated composite rudder system

Abstract

The invention discloses a flat integrated composite rudder system. The system comprises a base, a motor, a gear reducer, a composite lead screw assembly and a rocker assembly. The motor, the gear reducer, the composite lead screw assembly and the rocker assembly are arranged on the base; the composite lead screw assembly comprises a ball lead screw I, a ball nut I, a ball lead screw II and a ballnut II, the ball lead screw I is connected with the motor through the gear reducer and installed on the ball lead screw I, and the ball nut I and the ball nut II are fixedly connected; a slide block Iis arranged on the ball nut I, an anti-turning guide rail is arranged on the base, and the slide block I is installed on the anti-turning guide rail; the rocker assembly comprises a connection rod, aslide block II and a rocker. According to the flat integrated composite rudder system, integrated design of the rubber system and a wing is achieved, and the aims are achieved that the mass of the system is reduced, the transmission precision is improved, the mounting precision is improved, and the output torque is increased.

Description

technical field [0001] The invention belongs to the technical field of servo systems, and more specifically relates to a flat integrated composite rudder system. Background technique [0002] In recent years, with the continuous advancement of modern technology, the servo system is developing towards the design direction of miniaturization, long life, high efficiency and maintenance-free. Research on large aircraft, unmanned aerial vehicles, and cruise-guided missiles in my country has become one of the current hot spots. Because of its flat ailerons and flat distribution of internal space, it is quite difficult in system function layout. Therefore, the flat rotary rudder system integrated with the exoskeleton frame came into being. Compared with the traditional electric rudder system, it can greatly reduce the volume and mass of the system on the basis of ensuring the performance of the wing and steering gear structure. . From the perspective of the system, it has more s...

AI Technical Summary

Problems solved by technology

[0003] The rudder system is the executive functional part that realizes the deflection of the rudder blade during the flight of the aircraft. The traditional dynamic rudder system is limited by the transmission mode, and it is difficult to output a large torque in a flat and narrow space. If the output is increased by using multi-stage transmission Torque will increase the system error due to too many transmission links, thus affecting the accuracy of the rudder system

If the method of increasing the deceleration ratio of a certain link is adopted, there will be problems such as large installation space and increased mass of the steering gear, which will restrict the miniaturization of equipment such as drones and cruise guidance missiles.
