A Modular Assembled Two-dimensional Pointing Mechanism for Spaceborne Antenna

Abstract

The invention relates to a two-dimensional pointing mechanism for a modular and assembleable space-borne antenna, comprising: an X-axis motor drive assembly, a base, an X-axis resolver, an X-axis rotation body, a Y-axis motor drive assembly, and a Y-axis rotation body , Y-axis resolver antenna connection flange, waveguide assembly. The mechanism adopts a new modular assembly structure layout and optimized drive shaft design. According to different loads, motor drive components and angle sensors with different torques and precisions are selected. The core drive components and angle acquisition components are easy to disassemble and replace, and are convenient to be interchanged according to different load requirements; it can drive different loads within a certain range. Two-dimensional pointing function at different speeds, and the function of transmitting the position information of the load in two directions in a timely manner, especially suitable for institutions that require two-dimensional pointing for various types of space vehicles in the aerospace field, such as various antennas of satellites or other certain The scope turns to point to the desired device.

Description

technical field The invention relates to a two-dimensional pointing mechanism for a space-borne antenna, in particular to a modularized two-dimensional pointing mechanism for a space-borne antenna. Background technique The two-dimensional pointing mechanism of the space-borne antenna was used in the past in China. One type of space-borne antenna was equipped with a type of two-dimensional pointing mechanism for the antenna. Because different antennas have different pointing accuracy requirements, torque requirements and antenna loads, As a result, spaceborne antennas often correspond to a wide variety of two-dimensional pointing mechanisms for supporting antennas, and their versatility and interchangeability are relatively poor. It is often difficult to unify the pointing accuracy requirements and antenna loads of various antennas. The differences in spaceborne antennas are matched with different antenna two-dimensional pointing mechanisms, which will increase the product de...
