SUPPORTING-ROTATING STRUCTURE FOR ANTENNA WITH POLAR SUSPENSION OF REFLECTOR Russian patent published in 1997 - IPC

FIELD: space antenna devices. SUBSTANCE: device has base 1, tube 2, support 4, rack 8 with gears 12 and 13 for polar axis 14. In addition device has cross strut 24 and drives 21, 22 and 28 which drive reflector for local angle, azimuth and declination, respectively. Drive 21 which drives reflector for local angle is located in symmetry plane of support 4 and rack 8. Polar axis gears 12 and 13 are designed as radial sliding bearings and are located on opposite sides of reflector focal axis 27. Axis of cross strut 24 is displaced with respect to polar axis 14 towards reflector for reflector azimuth rotation by right angle. EFFECT: facilitated manufacturing and increased reliability while keeping given rigidity and local angle range of 0-90 for rotation of antenna reflector and azimuth rotation range of +/-90. 2 cl, 1 dwg
