Abstract

The invention provides a pointing mechanism with a micro-vibration isolation characteristic, and the mechanism comprises a first flexible support device, a second flexible support device, an azimuth angle movement mechanism and a rotary disc bearing gear, wherein the bottom of a pitching support base is fixedly connected to the azimuth angle movement mechanism; a first side ring of the first flexible supporting device is fixedly installed on the inner side of one end of the pitching supporting base, a fourth side ring of the second flexible supporting device is fixedly installed on the inner side of the other end of the pitching supporting base, one side of a first lug plate of the pitching platform is fixedly installed on a second side wheel, and the other side of the first lug plate is fixedly installed on a first driven wheel. One side of the second lug plate is fixedly installed on the third side wheel, and the other side of the second lug plate of the pitching platform is fixedlyinstalled on the second driven wheel. And a driving bevel gear of the driving mechanism is meshed with the driven bevel gear. According to the invention, the rigidity of a local structure on a micro-vibration transmission path can be reduced, and micro-vibration is isolated, so that the influence of micro-vibration on the control precision of the pointing mechanism is effectively solved.

Description

technical field [0001] The invention belongs to the field of pointing mechanisms, in particular to a pointing mechanism with the characteristic of isolating micro-vibration. Background technique [0002] With the continuous development of aerospace technologies such as deep space exploration, high-orbit mobile communication, and low-orbit networking, the communication volume between satellites and between satellites and the ground is increasing, and the transmission accuracy is getting higher and higher. The control accuracy requirements of the pointing mechanism are also increasing day by day. The pointing accuracy of the pointing mechanism directly determines whether the satellite antenna and other loads can perform scanning and positioning, and on the other hand directly determines the quality of communication between the satellite and the communication target. The pointing mechanism is the control and driving mechanism of the satellite antenna, etc. The pointing accuracy...
