Problems solved by technology

The supporting parts of the current design of the rotating platform all use bearing parts. These parts can well meet the supporting function during the rotating work, and the coefficient of rotational friction is extremely low. However, these parts need to be lubricated with lubricants. Considering To the use environment of the rotating platform in space, this poses a huge challenge to the design of bearing components

Abstract

The invention provides a large-angle flexible supporting device. The large-angle flexible supporting device comprises a first side ring, a second side ring and a triangular frame, three first supporting assemblies are arranged on the inner surface of the circumference of the first side ring, three second supporting assemblies are arranged on the inner surface of the circumference of the second side ring, first sliding heads of the three first supporting assemblies are connected to second sliding heads of the three second supporting assemblies through the triangular frame, and connection between the first side ring and the second side ring is achieved. The device has the advantages of no lubrication, few parts, good heat dissipation and the like, and can effectively support space rotation motion.

Description

technical field [0001] The invention belongs to the field of support devices, in particular to a large-angle flexible support device. Background technique [0002] With the development of aerospace technology, more and more satellites are equipped with payloads with rotation characteristics. These payloads themselves do not have motion functions. Generally, they are installed on a working platform with rotation characteristics. These rotating platforms drive the payload to move within a certain range, increasing the coverage of the payload, so designing rotating platforms suitable for complex environments has become the focus of current research. The supporting parts of the current design of the rotating platform all use bearing parts. These parts can well meet the supporting function during the rotating work, and the coefficient of rotational friction is extremely low. However, these parts need to be lubricated with lubricants. Considering To the use environment of the rot...
