Antenna is essential component in radio transmission apparatus, for receiving and sending wireless communication signal.Current
Antenna is integrally fixed on supporting rack mostly, and wireless communication signal is sent by the way of omnidirectional or orientation.In order to adapt to not Tongfang
The signal of position receives, and usually antenna is installed on antenna rotating platform and carries out orientation control.
Antenna rotating platform generally drives retarder, the output shaft band pinion gear of retarder by motor, then drives final stage gear wheel,
So as to drive antenna load to rotate.Gear pair usually has certain return difference.The return difference of gear pair has significant impact to equipment performance,
Equipment precision can be reduced.On the other hand, after antenna is fixed on antenna rotating platform, there is lasting pressure to antenna rotating platform, when long
Between under working status, antenna rotating platform causes the normal use for influencing antenna because deforming bearing the gravity of antenna.
Utility model content
The purpose of the utility model is to overcome the shortcomings that the prior art, there is provided a kind of precision height and the big day of load-bearing capacity
Line turntable structure.
The purpose of this utility model is achieved through the following technical solutions：A kind of antenna rotating platform structure, including base, the sun
Wheel, planetary gear and rotating seat, the base is columnar structured for upper opening, and internal tooth is equipped with the inner wall of the base
Enclose, axis hole is provided with the bottom center of the base, input shaft, the upper end of the input shaft and sun gear are housed in the axis hole
Be fixedly connected, be equipped with multiple planetary gears between the sun gear and the ring gear, each planetary gear respectively with sun gear and interior
Gear ring engages, and is installed with output shaft in the centre bore of the planetary gear, the lower end of the output shaft is fixedly connected with planetary wheel carrier, institute
State and lower ball grooves be provided with the inner bottom surface of base, the lower face of the planetary wheel carrier is provided with ball grooves, the lower ball grooves with
The upper ball grooves consistency from top to bottom, and more balls are provided between lower ball grooves and upper ball grooves, the output shaft it is upper
End is fixedly connected with rotating seat.
Further, the planetary gear has three, and three planetary gears are in 120 ° of interval settings.
Further, the planetary wheel carrier is an integral molding structure with the output shaft.
The utility model has the following advantages：
1st, the utility model uses planetary gear slowing-down structure, operates steadily, and output torque is big, and rotation precision is high.
2nd, the utility model is similar to thrust by installing multiple balls, formation between planetary wheel carrier and base inner bottom surface
The structure of ball bearing, so that base mainly carries the weight of antenna, and planetary wheel carrier stress is smaller, is not susceptible to deform,
Load-bearing capacity is high, and can remain high-precision smooth operation.
