ANTENNA VIEWING DEVICE Russian patent published in 2018 - IPC G01S13/02 

FIELD: radio engineering, communication.

SUBSTANCE: device contains a base, a mirror, a control unit, power antenna, which includes located based on rotation in azimuth mirror drive, output pinion which cinematically connected with cog-wheel installed on pipe fixed bearings and located coaxially to the axis of rotation in azimuth mirror, tilt mirror with output drive gear and rotating (rotary joint), which consists of a waveguide and ultrahigh-frequency tract. A fork plate is fixed in the upper part of the pipe. Inside the pipe there is a casing with a waveguide integrated into it, which is a rotating part of a non-contact microwave transmission. The stationary part of the rotational transition is fixed inside the sleeve, on the outside along the shaft is gear rod, cinematically connected with the output gear of the mirror tilt located on the base of the drive. In the inner part of the sleeve bearings are fixed, inner mobile rings are installed on the lower part of the casing. Centering on the circumference of the upper part of the casing is carried out by bearings installed in the through grooves located along the circumference of the pipe along its axis of rotation and in coincident slots on the outer part of the casing. The lateral surfaces of the bearings touch the side surfaces of the grooves of the pipe and, accordingly, the side surfaces of the casing slots, while the outer rings of these bearings run, respectively, the inner surfaces of the casing slots in the same direction. In coaxial located holes of the side parts of the fork plate, in bearings, shafts are installed with hooked on them bracket tilt axis which is perpendicular to the axis of rotation of the mirror azimuth. At one end of the bracket and mirror at the opposite end of the counterweight is placed, in the form of strips with central hole, which enshrined the rod. The console part of the rod is inserted into the hole of the clutch rollers arranged symmetrically to the rod in a vertical plane and horizontal connected with two sides symmetrically to the rod bearings, mounted on the bracket holder, still pinned to the top of the casing.

EFFECT: improving the balancing of the moving mirror of the antenna and simplifying the design of the entire antenna device.
