Pitching waveguide one 211 other ends (see figure 2) that is connected with an interface in orientation rotation joint 104.The other end of pitching waveguide 2 212 and polarized rotation joint 311(polarizing unit, an interface as shown in Figure 6) is connected.
Polarization part 3
Mainly by primary reflection surface, subreflector, feed, resolver, polaxis and bearing, polarization transmission mechanism etc., formed.
As shown in Figure 7,8, antenna surface fixed head 306 is connected by screw with polarizing unit connector 220 and polarizing unit connector 229, has reached being connected of polarizing unit and pitching parts.Bearing 307 be fixed on antenna surface fixed head 306 in the heart, polaxis 317 is through the inner ring of bearing 307, its shaft shoulder compresses the lower end of bearing 307 from bottom to up simultaneously.Antenna main reflector fixture 305 compresses bearing 307 outer rings from top to bottom, on antenna surface fixed head 306, primary reflection surface 303, bearing 307 and antenna main reflector fixture 305 and antenna surface fixed head 306 coaxial (polaxis) assembling, and link together with screw.
Polarization is revolved and is become strutting piece 319 compression bearing 307 inner rings downwards, upwards compresses the inner ring of polarization rotation transformer 304.Polarization is revolved change Axial Mounting Part 302 and is connected with antenna main reflector fixture 305 use screws, and polarization is simultaneously revolved and become the outer ring that Axial Mounting Part 302 compresses the rotation transformer 304 that polarizes downwards.Feed fixture 320 is fixed on to revolve and becomes strutting piece 319 upper ends, and compresses the inner ring of polarization rotation transformer 304 downwards.Feed 318 is fixed on feed fixture 320, and upper end and subreflector fixture 312 are connected by screw simultaneously, and subreflector 301 is fixed by screw with subreflector fixture 312, and subreflector 301 is positioned at the central shaft top of polarizing unit.
Polarization driven transmission wheel 308 is screwed in polaxis 317 bottoms, polarization transmission driving wheel 313 is screwed in polarization motor 316 axial end, polarization motor fixture 314 is screwed polarization motor 316, and polarization motor fixture 314 is fixed on antenna surface fixed head 306.It is 308 intermeshing that polarization transmission driving wheel 313 and polarization driven transmission are taken turns, and drives polaxis 317 to rotate together, and on polaxis, related parts rotate together.
Poled waveguide 1 is connected in the lower end of polaxis 317, and polarized rotation joint 311 is connected in the lower end of poled waveguide 1.The spacer flanger of poled waveguide 1 connects one end of filter 310, and the other end of filter connects poled waveguide 2 315, and the other end of poled waveguide 2 315 is connected with LNB321.Polarized rotation joint has connected poled waveguide 1, pitching waveguide 2 212 altogether.
The machine work principle of whole antenna is:
When orientation parts carry out work, the azimuth-drive motor 112 being arranged on pitching bearing drives orientation driving wheel 113 and bearing 102 outer ring engagements, and orientation driving wheel 113 rotates around the orientation centre of gyration.Now because azimuth-drive motor 112 is fixed on azimuth-drive motor fixture on 114, and azimuth-drive motor fixture 114 is fixed on pitching bearing platform 229, so must drive pitching bearing polarizing unit whole and that be fixed on above pitching bearing integral body to rotate together when azimuth-drive motor 112 rotates.At centre of gyration position, orientation, orientation rotation back shaft 111 is connected and fixed with pitching bearing platform 229, collector ring 101 inner rings, orientation rotation back shaft 111 is tightly fixed with orientation rotation transformer 105 inner rings simultaneously, so these parts also carry out 360 ° of Infinite Cyclic rotations with azimuth-drive motor 112 around the orientation centre of gyration.Due to the particularity of orientation rotation joint 104 structures, in whole rotation process, its upper end is followed rotating part and is rotated together, and lower end maintains static with respect to azimuth base 103.
When pitching component working, pitching driving motor 205 drives pitching transmission driving wheels 215, rotates, but due to spacing and can not 360 ° of rotations, can only swing with 217 engagements of pitching driven transmission wheel around the pitching centre of gyration.What now participate in together motion has axle 1, resolver 202 inner rings, bearing 207 inner rings, axle 2 224, bearing 223 inner rings, and polarizing unit connector 220 and 228, and the polarizing unit being connected with polarizing unit connector 220,228.What pitching realized is the pitching of the pitching centre of gyration.
When polarizing unit is worked, polarization motor 316 drives polarization transmission driving wheel 313, with 308 engagements of polarization driven transmission wheel, around the polaxis centre of gyration, rotates.Now, polaxis 317, poled waveguide 1, filter 310, poled waveguide 2 315, LNB321, bearing 307, revolve and become strutting piece 319, feed fixture 320, feed 318, subreflector fixture 312, subreflector 301 and rotate together.Meanwhile, polarized rotation joint 311 drives pitching waveguide 2 212 and pitching rotary joint 208 to rotate together.What this part realized is that polarizing unit is around the rotation of polarization central shaft.Because pitching joint 208 structures have particularity, it is comprised of inside and outside two parts, and there is rotating shaft the inside, so exterior portion can maintain static, rotating shaft part in the inside can be rotated.
In general, when antenna receives that signal that in control assembly box 233, servo control unit sends rotates, orientation part, pitching part, polarization part can be distinguished independent rotation, also can rotate simultaneously.Realize the integrated motion of orientation, pitching, polarised direction, with this, realize all-direction rotation and follow the tracks of.
