Abstract

The invention provides a vehicle-mounted antenna turntable with a low main body profile. The vehicle-mounted antenna turntable comprises a bottom plate, a motor, a speed reducer, a slewing bearing with an external gear, a power pinion, a turntable, a rotary combination, a diaphragm coupling, a rotary combination mounting seat and a protective cover. According to the vehicle-mounted antenna turntable with the low main body profile, the structural form and the stress mode of a base are changed, and the bottom plate can be lower than a base of a common rotary table, so that the mounting height ofan antenna feeder system is increased; an angle measurement sensor is integrated in the rotary combination, a data transmission chain of the common rotary table is omitted, the influence of the datatransmission chain on the angle measurement precision can be overcome, and precise detection of the rotation angle of the rotary table is achieved; the protective cover is arranged, particularly, theslewing bearing protective cover adopts a special labyrinth sealing mode, rainwater and impurities can be prevented from entering the slewing bearing protective cover, and inspection and maintenance work operation is convenient.

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...
