Abstract
The utility model discloses a flat plate direct-coupled rotating structure for an azimuth shaft and a pitch shaft. The rotating structure comprises an azimuth main shaft, a pitch rotating shaft and a pitch rotating shaft support frame, wherein the pitch rotating shaft support frame adopts a flat plate structure; the bottom of the flat-plate structured pitch rotating shaft support frame is fixed on a main shaft outer sleeve of the azimuth main shaft, and the top thereof is supported on the pitch rotating shaft. As the azimuth shaft and the pitch shaft adopt a flat-plate direct coupling, the integral height of a pitch rotating mechanism is effectively reduced, and the occupied area of a power amplifier mounting plate is reduced; and as a power amplifier can be mounted in the rotating structure, which ensures that the power amplifier is close to the feed source of an antenna, the signal circuit loss is reduced, and the adaptability is improved.
