Embodiment Construction

[0020] The present invention will be described in further detail below. see Figure 1-3 , a self-locking steering gear, including a sliding bearing seat 1, a rudder plate 2, a cylindrical pin 3, a double-row torsion spring 4, a gear shaft 5, a steel ball 6, a compression spring 7, a slotted flat end set screw 8, a sliding bearing 9. Sliding lead screw 10, motor 11, housing 12, rack nut 13, leading screw end sliding bearing 14, magnetic steel base 15, magnetic steel 16, magnetic encoder chip 17 and circuit board 18. Wherein, the shaft of the motor 11 is bonded coaxially with the sliding screw 10, and the rack nut 13 is screwed with the sliding screw 10. At the same time, the rack nut 13 is also meshed with the gear shaft 5, and the rudder blade 2 is installed via the cylindrical pin 3. On the gear shaft 5, the magnetic steel 16 is installed in the magnetic steel seat 15 bonded with the sliding screw 10, the double-row torsion spring 4 is installed on both sides of the gear sha...

Abstract

The invention belongs to the field of aircraft control, in particular to a self-locking steering engine. The existing steering engine mostly adopts a motor with a reducer mechanism, and thus the existing steering engine is not applicable in narrow space and does not have a self-locking function. The self-locking steering engine is used for controlling a plurality of rudders in the narrow space, and comprises a cylindrical shell body, wherein a plurality of rudder blade assembly mounting holes are uniformly distributed along an annular surface, and a corresponding number of driving assembly mounting holes and folding groove openings of the rudder blades are formed in the end surface. The steering engine is self-locking when there is no action command, and the rudder blades can be automatically unfolded in place and locked.

Description

technical field [0001] The invention belongs to the field of aircraft control, and in particular relates to a self-locking steering gear. Background technique [0002] The steering gear is a position angle servo drive, suitable for those control systems that need to change and maintain the angle constantly. In the existing technology, the steering gear mostly uses a motor with a reducer mechanism, which has the advantages of compact structure, easy installation and debugging, simple control, and low cost. However, this steering gear is not suitable for small spaces and does not have a self-locking function. , the deployment of the rudder blades is not considered. Contents of the invention [0003] In view of the above problems, the present invention provides a steering gear that can realize simultaneous operation of four rudders that are circumferentially symmetrical in a narrow space, self-locking when there is no action command, and the rudder blades can be automaticall...
