Problems solved by technology

[0005] 1. The drive form of worm gear is adopted, and its input shaft and output shaft are distributed orthogonally, which leads to a large envelope size of the drive device, which is not conducive to the overall layout design of the drive device and antenna
[0006] 2. The drive device in the form of a brake, relying on the friction plate to achieve tight locking, the disadvantage is that the drive device does not have a convenient manual adjustment function

Abstract

The invention discloses a self-locking driving device for a satellite communication antenna, and belongs to the technical field of antennas. The self-locking driving device comprises an input shaft, an input shifting fork, an output shaft, a limiting spring and a limiting pin roller, wherein the input shaft can drive the input shifting fork to rotate left and right, the input shifting fork shifts the limiting spring and the limiting pin roller to rotate, and then the output shaft is driven to rotate. When an output flange is subjected to forward or reverse torque action of an external load, the driving device has a bidirectional self-locking function through the limiting action of the limiting spring and the limiting pin roller. The self-locking driving device realizes parallel arrangement of the input shaft and the output shaft, facilitates adjustment of the pointing angle of the antenna, is small in appearance envelope size, and is conductive to layout design of the overall structure of the antenna; and meanwhile, the driving device has a bidirectional self-locking function, so that locking and maintaining of a satellite communication antenna beam angle can be realized.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a self-locking driving device for a satellite communication antenna. Background technique [0002] Satellite-to-ground antennas are used more and more in satellite-ground information transmission, emergency communications, earthquake relief and other fields, which greatly expands the scope of information transmission and improves the speed of information transmission. [0003] The satellite communication antenna needs to have the locking and holding function of the beam angle, so as to ensure the stability of the satellite communication link. Therefore, the driving device of the satellite antenna needs to have a self-locking function. [0004] In order to realize the self-locking function, the existing satellite antenna driving device generally adopts two forms of worm gear driving or holding brake. Adopt the drive device of above-mentioned two forms to have the weak point of ...
