Embodiment Construction

[0013] Such as figure 1 — image 3 shown. A three-axis turntable, including a lower base 1 with an open top, lower motors 2 with vertically upward output shafts installed on both sides of the lower base 1, each output shaft of the lower motor 2 is driven and connected with The lower gears, the output shafts of each lower gear are vertically upward and fixed with the lower pinions 3, the lower base 1 is open to the top, and the inner tooth type lower slewing bearing 4 is installed for rotation, and the two lower gears are small. The external teeth of the gear 3 are meshed with the internal gears of the internal-toothed lower slewing bearing 4 respectively, and the top of the lower base 1 is provided with a lower turntable 5 fixed on the top bearing surface of the inner-toothed lower slewing bearing 4. A lower confluence ring 6 is arranged in the center of the base 1, and a lower resolver 7 is installed on the top of the lower confluence ring 6. The rotating inner ring of the ...

Abstract

Disclosed in the invention is a three-shaft rotary table. A lower orientation rotating plate, an upper orientation rotating plate, a pitch shaft, and transmission mechanisms respectively connected with the lower orientation rotating plate, the upper orientation rotating plate, and the pitch shaft are arranged, thereby realizing orientation adjustment of an antenna at three-shaft directions. According to the invention, the motion displacement of the whole structure is large; a motion signal is transmitted externally by a rotation transmitter and a collector ring, so that the signal can be transmitted conveniently; and the three-shaft rotary table has the high controlling precision.

Description

technical field [0001] The invention relates to the field of antenna turntables, in particular to a three-axis turntable. Background technique [0002] The antenna turntable is used to carry the antenna. Through the movement of the turntable, the orientation function of the antenna in the three-axis direction of the coordinate axis is realized to guide the antenna to accurately point to the target. Due to the limitation of the internal mechanical structure, the antenna turntable in the prior art has the problems of small motion stroke, poor control precision and difficult motion signal transmission. Contents of the invention [0003] The purpose of the present invention is to provide a three-axis turntable to solve the problems existing in the prior art antenna turntable. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A three-axis turntable, characterized in that it includes a lower base with an open top,...
