Abstract
The invention provides an electric steering engine. The electric steering engine comprises a motor, a speed reducer and a feedback potentiometer, wherein the speed reducer comprises a bevel gear, a gear module, a straight gear and an output shaft, wherein the bevel gear is meshed and connected with an output shaft of the speed motor, the gear module is meshed and connected with the bevel gear, the straight gear is meshed and connected with the gear module; the output shaft is connected with the straight gear; in addition, the feedback potentiometer is connected with the output shaft. According to the electric steering engine, the special structure of the straight gear connected with the output shaft is designed; on the basis that the load bearing strength of the electric steering engine is not damaged, the occupied space and weight of the steering engine are greatly reduced, and the application range of straight-tooth-type electric steering engines is enlarged.
Description
Technical field
The present invention relates to flying vehicles control device field, particularly relate to a kind of electric steering gear.
Background technology
Electric steering gear is as servo actuator, there is structure simple, the features such as process and assemble is easy, and track laying, manufacture maintenance and repacking are all more convenient, obtain applying more and more widely in the aircraft such as unmanned plane, guided missile, associating guided munition (JDAM) and spacecraft.Along with the development of technology, the performance of aircraft to steering wheel is had higher requirement, and impels steering wheel constantly to reduce towards quality, volume, the future development that load-carrying capacity constantly strengthens.Retarder is as the vitals of electric steering gear, in steering gear system, adopt at present the deceleration mode of harmonic reduction (such as CN103523207A) or ball-screw deceleration (such as CN201224496Y) more, however the retarder manufacture difficulty of this kind of pattern and cost all higher.On the basis meeting steering gear system function, spur reduction device due to its process and assemble difficulty little, low cost and other advantages also obtain to be applied widely, such as patent CN203570932U propose small-sized steering machine gear case etc.The retarder of straight-tooth type is in order to obtain higher load-carrying capacity and intensity, the strength of gear teeth be connected with steering wheel output shaft is maximum, therefore the volume and weight of this gear is all comparatively large, which limits the application adopting the steering wheel of this kind of retarder steering wheel volume weight to be had to the occasion of rigors in finite space.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of electric steering gear, and the fuction output meeting Electrodynamic Rudder System requires and can effectively reduce size and the weight of steering wheel, adapts to the installation requirement under limited space conditions.
Technical scheme of the present invention is:
A kind of electric steering gear, comprising: motor, retarder and feedback potentiometer; Retarder comprises: finishing bevel gear cuter, the output shaft of the motor that is connected with a joggle; Gear assembly, be connected with a joggle finishing bevel gear cuter; Straight gear, be connected with a joggle gear assembly; Output shaft, connects straight gear; In addition, feedback potentiometer is connected with output shaft.
Further, gear assembly comprises the multiple gears engaged step by step.
Further, straight gear is connected with output shaft interference or flat key.
Further, straight gear is sector structure.
Further, the gear in gear assembly is fine module gear.
Further, finishing bevel gear cuter and straight gear are fine module gear.
The present invention's advantage is compared with prior art:
The present invention is by carrying out special construction design to the straight-tooth gear be connected with output shaft, on the basis of not losing electric steering gear loading strength, greatly reduce taking up room and weight (about reducing 3/4) of steering wheel, expand the field of application of the electric steering gear of straight-tooth type.

The present invention is a kind of electric steering gear, as shown in Figure 1, this electric steering gear mainly comprises motor 1, retarder, feedback potentiometer 6, and retarder mainly comprises cover plate 7, casing 8, finishing bevel gear cuter 2, first gear assembly 3, second gear assembly 4, the 3rd gear assembly 5, straight gear 9 and output shaft 10.
Motor 1 and finishing bevel gear cuter 2 connect firmly, the power of motor to be engaged with the finishing bevel gear cuter on the first gear assembly 3 by finishing bevel gear cuter 2 thus is delivered to the first gear assembly 3, then be delivered in straight gear 9 by the gears meshing step by step of the first gear assembly 3, second gear assembly 4, the 3rd gear assembly 5 and straight gear 9, straight gear 9 is by being connected with the interference or flat key of output shaft 10 transmission realizing power.Feedback potentiometer 6 and output shaft 10 connect firmly, and after control signal sends, by the signal feedback of feedback potentiometer 6, realize exporting the control of electric steering gear.Above-mentioned all gears are fine module gear.Straight gear 9 is sector structure.
Casing is for holding finishing bevel gear cuter 2 and each gear assembly of retarder, and cover plate is used for the open side of closed box.
The unspecified part of the present invention belongs to general knowledge as well known to those skilled in the art.
