Satellite-borne load linear motion system

Abstract

The invention discloses a satellite-borne load linear motion system which comprises a load assembly and a linear track fixed on a satellite body. The linear rail is a foldable rail; the load assemblycomprises a moving mechanism, a driving mechanism and a load mechanism for bearing a corresponding load; the moving mechanism is assembled on the linear rail, the linear rail provides acting force forlimiting the moving mechanism to be separated from the linear rail, the moving mechanism can be driven by the driving mechanism to move on the linear rail, and therefore the load can complete high-precision long-time reciprocating motion in the foldable rail. By means of the foldable structure, the distance of the linear orbit can be longer after the linear orbit is unfolded, the satellite load envelope requirement can be met, and meanwhile the long-distance reciprocating linear motion of the load can be met; the moving mechanism can move on the linear rail all the time and cannot be separated from the linear rail to fail in the weightless state, and therefore the load linear motion system can still normally move in the weightless state.

Description

technical field [0001] The invention relates to the technical field of linear drive mechanisms, in particular to a linear motion system suitable for spaceborne applications. Background technique [0002] With the continuous development of aerospace technology, in order to obtain better electrical performance of satellite payloads, the payload system is becoming more and more complex, and the requirements are getting higher and higher, and the space occupied by the payload is getting larger and larger. With the continuous increase of the load system, the required drive mechanism is also getting larger and larger, and the existing drive mechanism cannot meet the use requirements. In order to better cooperate with the satellite load system, it is urgent to break through the inherent mode of the drive mechanism and study a Applicable to space-borne linear motion systems. [0003] Existing space-borne linear motion systems are generally small in size, one-time unfolding or closi...
