Abstract

The invention provides a pointing mechanism with the characteristic of isolating micro-vibration, including No. 1 flexible support device, No. 2 flexible support device, an azimuth movement mechanism, a turntable bearing gear fixedly connected to the bottom of the pitch support base to the azimuth movement mechanism, and a The No. 1 side ring of the No. 1 flexible support device is fixedly installed on the inside of one end of the pitch support base; the No. 4 side ring of the No. 2 flexible support device is fixedly installed on the inside of the other end of the pitch support base; On the No. 2 side wheel, the other side of the No. 1 lug plate is fixedly installed on the No. 1 driven wheel; one side of the No. 2 lug plate is fixed on the No. 3 side wheel, and the other side of the No. 2 lug plate on the pitching platform is fixedly installed on the No. 2 driven wheel. The driving wheel; the driving bevel gear of the driving mechanism meshes with the driven bevel gear. The invention can reduce the rigidity of the local structure on the micro-vibration transmission path and isolate the micro-vibration, thereby effectively solving the influence of the micro-vibration on the control precision of the pointing mechanism.

Description

technical field [0001] The invention belongs to the field of pointing mechanisms, and in particular relates to a pointing mechanism with the characteristics 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 amount of communication between satellites and between satellites and the ground is increasing, and the transmission accuracy is getting higher and higher. The requirements for the control accuracy of the pointing mechanism are also increasing. The pointing accuracy of the pointing mechanism directly determines whether the satellite antenna and other loads can be scanned and positioned. On the other hand, it directly determines the advantages and disadvantages of the communication between the satellite and the communication target. The pointing mechanism is the control and driving mechanism of the satellite ante...
