3rd duplicate gear is made up of No. four gears 4 and No. five gears 5, and No. four gears 4 are arranged under No. five gears 5 Side;4, No. three gears 3 of No. four gears engage with 2, gear 1 of No. two gears connect respectively;No. five gears 5 and No. six gears 6 Engagement connects.
Number 5, No. six gears 6 of gear of gear 3, five of gear 1, three are partial gear, and a gear 1 and three Engaged when different between number gear 3, between No. five gears 5 and No. six gears 6;If controlled motor 12 drives a up time of gear 1 Pin rotates:When a gear 1 is meshed with No. three gears 3, No. six gears 6 and No. three gears 3 synchronously rotate counterclockwise;When five When number gear 5 is meshed with No. six gears 6, No. six gears 6 are rotated clockwise;When above two state interval occurs, you can Three or six the rotating back and forth in certain angle of double crosslinking gear shaft 8 are realized, so as to realize the sectoring of scanner 10.
Accumulator 9 is double moment of torsion cylindrical springs, and its two ends are separately fixed on No. three gears 3 and No. six gears 6, separately One end is then fixedly installed on housing 11.Accumulator 9 can absorb or release kinetic energy during, backwards rotation suitable in No. six gears 6, effectively Reduce impact of the gear when turning to, the service life of extension fixture.
A number gear 1 is identical with the pitch circle of No. two gears 2;No. three gears 3 are identical with the pitch circle of No. four gears 4;No. five teeth Wheel 5 is identical with the pitch circle of No. six gears 6.
A kind of scan method of at the uniform velocity sectoring device, detailed process is as follows:
Working power is opened, controlled motor 12 starts, and drive a gear 1 and No. two gears 2 to turn clockwise;This When, a gear 1 is meshed with No. three gears 3, and No. five gears 5 and No. six gears 6 are not engaged;
When a number gear 1 and No. two gears 2 rotate clockwise, No. three gears 3 and No. four gears 4 are to the anti-of engagement Direction is counterclockwise rotates, and drives No. six coaxial gears 6 of their upper ends and No. five gears 5 respectively counterclockwise Rotation;
When No. six 6 rotation alpha angles of gear, counterclockwise scanning of the scanner 10 in α scopes is realized immediately;Will this moment one Number corresponding anglec of rotation of gear 1 is labeled as β;
When a gear 1 continues to rotate clockwise into γ angular ranges under the drive of controlled motor 12, a tooth Wheel 1 is not engaged with No. three gears 3, and No. five gears 5 and No. six gears 6 are meshed;
With rotating clockwise for gear 1, No. four rotate counterclockwises under No. two engagements of gear 2 of gear 4, No. five rotate counterclockwises of gear 5 are driven simultaneously, and No. six gears 6 is turned clockwise under No. five engagements of gear 5, it is real Existing scanner 10 is scanned in the backhaul clockwise of α scopes;
When a gear 1 continues to turn clockwise traveling to next β angles, scanner 10 can be driven again in α scopes Scanned counterclockwise, so gone round and begun again, constantly circulation, is realized the uninterrupted sectoring of scanner 10;
No. six gears 6 and No. three gears 3 during suitable, inverse coaxial rotating, by accumulator 9 carry out energy absorption and Release, makes device effectively be buffered, and reduces to driving wheel and the elliptical gear of driven pulley;And accumulator 9 discharges in energy During, and because a gear 1 and No. five restriction effects of gear 5 cannot be inverted quickly, so as to ensure that scanning The uniform speed scanning of device 10.
Three groups of duplicate gears can also use ratchet, sheave, cam (including electric cam), crank and rocker mechanism etc. in the present invention Intermittent motion mechanism substitutes, but is difficult to the uniform rotation of output shaft;Accumulator is double moment of torsion cylindrical springs, it is also possible to single Moment of torsion cylindrical spring, leaf spring, weight, electromagnetic storage device etc. are various can be substituted with the component of accumulation of energy or device, but present invention dress The structure put is simpler, the more reliable, cost that works is less expensive.
The present invention has the advantage that compared with conventional art:
(1), the transmission mechanism that three groups of duplicate gears are engaged respectively, take full advantage of gear drive at the uniform velocity, steadily, engaging tooth Rotating backward between wheel and duplicate gear are coaxially same to be turned to the characteristics of with rotating speed, makes the present invention have the fast steady, scanning of biography equal Even advantage.
(2), using the intermittent movement feature of imperfect gear, with reference to the transmission mechanism that three groups of duplicate gears are engaged respectively, Realize input shaft (motor) and turn to fixed, the at the uniform velocity uninterrupted rotating campaign of output shaft.
(3), by the use of double-torsional spring as accumulator, the torsion potential energy of system rotating is absorbed and is discharged, effectively reduce System rotates impact during commutation, makes system motion more steady, and transmission system associated components, motor, scanner are rushed from vibrations Hit, the service life of extension fixture.
Above-mentioned implementation method is not limitation of the present invention, and the present invention is also not limited to the example above, this technology neck Change, remodeling, addition or replacement that the technical staff in domain is made in the range of technical scheme, also belong to this hair Bright protection domain.
