Abstract

The invention provides a vehicle-mounted antenna turntable with a low main body profile, including a bottom plate, a motor, a reducer, a slewing bearing with an external gear, a power pinion, a turntable, a rotary assembly, a diaphragm coupling, a rotary assembly mounting seat and a protection cover. The bottom plate of the present invention changes the structural type and force bearing mode of the base, and the bottom plate can be made shorter than the base of a general turntable, thereby increasing the installation height of the antenna feeder system; the angle measuring sensor of the present invention is integrated in the rotation combination, eliminating The data transmission chain of the general turntable can overcome the influence of the data transmission chain on the angle measurement accuracy, and realize the precise detection of the rotation angle of the turntable; the invention is equipped with a protective cover, especially the special labyrinth sealing method for the slewing bearing protective cover, which can prevent rainwater , Sundries enter, and the inspection and maintenance work is easy to operate.

Description

technical field [0001] The invention relates to the field of antenna transmission devices, in particular to a vehicle-mounted antenna turntable with a low main body profile. Background technique [0002] Many antenna feed systems in the fields of radar and communication require a set of antenna transmission devices to support the load of the antenna feed and drive the antenna to rotate and point to a predetermined direction as required. [0003] Antenna turntables generally have components such as motors, reducers, bearings, slip rings, data transmission chains, angle sensors, bases, and turntables. The motor drives the reducer, and then drives the antenna load to rotate. The bus ring is used for the transmission of various electrical signals and electric energy between the rotating part and the fixed part. The data transmission chain is coupled with the rotating shaft of the turntable through the gear pair, and its output shaft is coupled with the angle sensor, and the an...
