Abstract

The invention provides a compact steering engine and a steering engine cabin. The compact steering engine comprises a motor, a coupling, a lead screw, a lead screw fixing frame, a lead screw nut, a nut seat, a connecting piece, a connecting rod, a joint bearing, a first dialing pin and a second dialing pin. The motor is connected with the lead screw through the coupling. Power of the motor is transmitted to the lead screw. The lead screw is fixed on the lead screw fixing frame. The lead screw nut is mounted on the lead screw and is fixedly connected with the nut seat. The connecting piece is connected with the connecting rod through the second dialing pin. The connecting rod and the connecting piece have no relative displacement in the z-axis direction while can rotate relatively in the xyplane. The compact steering engine is simple in structure, high in mechanical transmission efficiency and small in transmission gap.

Description

technical field [0001] The invention relates to the technical field of electric steering gear, in particular to a compact electric steering gear. Background technique [0002] With the miniaturization of aircraft, the miniaturization of steering gear is also an inevitable trend of its development, which has attracted extensive attention from scholars at home and abroad. As the actuators of aircraft, missiles and robot systems, the steering gear plays a key role in the normal operation of the entire system. The driving forms of traditional steering gears are pneumatic and hydraulic, but this kind of steering gear has complex structure, large mass, large volume and high cost. With the use of the fly-by-wire control system and the formation of the concept of an all-electric aircraft, the electric steering gear has the advantages of simple structure, easy processing and assembly, reasonable line laying, convenient manufacturing, maintenance and modification, and can use the sam...
