Abstract

The invention discloses a long-service-life electric steering engine which comprises a potentiometer, a motor, a bevel gear pair driven by the motor, and a speed reducer driven by the bevel gear pair, wherein the speed reducer comprises a first small-teeth-difference internal gear pair consisting of a first external gear and a first internal gear, a second small-teeth-difference internal gear pair consisting of a second external gear and a second internal gear, and an eccentric shaft driven by the bevel gear pair, wherein the first external gear and the second external gear are fixedly connected to the eccentric shaft to form two stages of planet transmission, the second internal gear is fixedly connected to a housing of the long-service life electric steering engine, the first internal gear is used for driving a load to rotate, and the transmission ratio of the first small-teeth-difference internal gear pair is more than that of the second small-teeth-difference internal gear pair. The long-service life electric steering engine disclosed by the invention realizes the long service life and high reliability based on a small-teeth-difference planet gear speed reducer, and meets the requirement of an intermediate and long-range aircraft on the long service life. The invention also discloses an aircraft employing the long-service life electric steering engine.

Description

technical field [0001] The invention relates to the technical field of electric steering gear, in particular to an aircraft and its long-life electric steering gear. Background technique [0002] The electric rudder system is the executive mechanism of the guidance and control system of missiles and UAVs. It is mainly composed of electric steering gear, controller and feedback components. The controller receives the signal output by the missile or UAV controller and drives the electric steering gear to control the missile. Or the wing of the UAV, relying on the aerodynamic force and aerodynamic resistance moment generated by the wing deflection of the projectile or the UAV during flight, to stabilize and control the projectile, so that the projectile flies according to the set trajectory and directly hits the target. In order to improve the performance of the electric steering gear, the output of the electric steering gear is fed back to the input end to form a follow-up, al...
