Abstract
A small gear case for a steering engine comprises an upper casing, a lower casing, a motor assembly, a first gear set, a second gear set, a third gear set and a fourth gear set. Engagement of the four stages of gear sets transmits movement and power input by the motor to the output shaft. When the system functions are satisfied, the size of the gear case can be reduced by optimizing the structure, thereby solving the problems of being small, and light and restricted by dimension of an electric steering engine during research.
Description
Technical field
The utility model relates to steering wheel transmission system technical field, particularly relates to small-sized gearbox technical field.
Background technique
Steering wheel gear-box is as the actuating device of missile brain, and the controlled angle order that acceptance is sent here by missile-borne computer, in order to the deflection angle of primary control surface, thereby produces certain hinge moment, makes guided missile produce the flight attitude requiring.
Steering wheel, as the core component of rudder system, is generally divided into hydraulic sterring engine, pneumatic servo (being subdivided into cold air steering wheel and combustion gas steering wheel) and electric steering engine by the difference of energy system.
In the last few years, along with the development of high-performance direct current servomotor and high efficiency reducing gear, electric steering engine has easy to use, does not leak, conform with missile-borne energy unification requirement, its research, development and application aspect tactical missile will more and more be goed deep into.
Model utility content
The utility model object is that a kind of volume of proposition is little, quality light, its basic principle is to utilize fine module gear system, meets the transmission requirement of steering gear system in strict physical dimension restriction lower tooth train.
The utility model is achieved through the following technical solutions: small-sized steering machine gear-box, it is characterized in that by upper box, lower box, electric machine assembly, and gear train one, gear train two, gear train three, gear train four form, and wherein electric machine assembly comprises motor and gear one.Gear train one comprises gear two and gear shaft two, and gear train two comprises gear three and gear shaft three, and gear train three comprises gear four and gear shaft four, and gear train four comprises gear five and output shaft, gear one connects firmly with motor, and with gear two engagements, the motion of motor and power are transmitted, gear two forms assembly together with fixed connection between gear shaft two, the motion of motor and power are delivered to gear shaft two through one-level gear transmission, gear three has gear pair with gear shaft two, gear three and gear shaft three connect firmly and through gear shaft two, are delivered on gear shaft three for gear train two power, gear four forms gear pair with gear shaft three, gear four connects firmly and is related to that power is delivered on gear shaft four through gear shaft three with gear shaft four, gear five will move with transmission of power to output shaft with gear shaft four engagements.
The utlity model has following technique effect:
By gear one, by motion and the power of motor output, after level Four gear reduction, make output shaft there is nominal torque 40N.m, rated speed Ω=100 °/S, and meet the requirement of system trace performance.
Accompanying drawing explanation
Fig. 1-1 is each constituent element schematic diagram of gear-box, and Fig. 1-2 is Fig. 1-1A-A view.
Fig. 2 detects steering wheel gear-box system for tracking situation schematic diagram.
Embodiment
Fig. 1 (1-1 and 1-2) is for the utlity model has small-sized steering machine gear-box schematic diagram, gear-box is by upper box 6, lower box 8, electric machine assembly 9, gear train one, gear train two, gear train three, gear train four (in Fig. 1-2, mark 1-5 is gear) form, wherein electric machine assembly comprises motor and gear one, gear train one comprises gear two and gear shaft two, gear train two comprises gear three and gear shaft three, gear train three comprises gear four and gear shaft four, and gear train four comprises gear five and output shaft 7.Gear one connects firmly with motor, and with gear two engagements, the motion of motor and power are transmitted, because gear two forms assembly together with fixed connection between gear shaft two, so the motion of motor and power are delivered to gear shaft two through one-level gear transmission, and gear three has gear pair with gear shaft two, gear three is again to connect firmly component relation with gear shaft three, so power is delivered on gear shaft two through gear shaft two, now, gear four forms gear pair with gear shaft three, gear four has with gear shaft four relation of connecting firmly, so power is delivered on gear shaft four through gear shaft three, final gear five and gear shaft four engagements, to move with transmission of power to output shaft.Thereby complete the whole process that is input to output shaft output from motor.
Gear shaft in this gear-box and the modulus of gear are all less than 1, all belong to fine module gear, thereby reduce the external dimension of gear-box.Between each gear assembly diaxon, relative position is parallel relation, uses topological approach to be optimized train of gearings, makes velocity ratio maximum in certain space, reaches 320.In order to meet the assembly relation between steering wheel, between assurance, do not interfere, the angle of gear train one axis and gear train two axis place planes and gear train three axis and gear train four axistyle place plane is 22 °.Final gear-box external dimension: long, wide, height is respectively: 117mm, 60mm, 12.5mm.
Fig. 2 detects steering wheel gear-box system for tracking situation schematic diagram.This test event mainly examine steering wheel following rate under rated load 30Nm condition whether whether meet >=100 °/s and system overshoot≤5%, from test data is calculated, steering wheel gear-box following rate is 127 °/s, system non-overshoot.
