Abstract

The invention relates to a rolling supporting assembly allowing on-rail changing. The rolling supporting assembly includes a clamping device and a bottom installation portion; the clamping device is movably arranged on the bottom installation portion through a sliding platform; the clamping device includes a first clamping portion, a second clamping portion, and a bottom clamping portion; the first clamping portion, the second clamping portion and the bottom clamping portion are movably arranged on the sliding platform; and the three clamping portions clamp a rotation guide rail together. Thetechnical scheme can stably clamp and support the rotation guide rail, is less in friction abrasion, and can solve the technical problem that clamping and supporting is not stable and friction abrasion is serious in the prior art.

Description

technical field [0001] The invention relates to a device for clamping and supporting a rotating guide rail used in a sun-orientation device of a space station, in particular to an on-rail replaceable rolling support assembly. Background technique [0002] The slewing support mechanism is used in the sun orientation device of the space station. It includes a rolling support assembly and a rotating guide rail. The rolling support assembly is used to clamp and support the rotating guide rail to ensure the continuous and stable rotation of the solar wing. [0003] First of all, in the rolling support assembly, the clamping part, as the most important component of the rolling support assembly, is used to clamp the rotating guide rail. The rolling support assembly consists of two parts, the mounting base and the clamping part. However, in the prior art, after the clamping part clamps the rotating guide rail, it cannot still maintain good line contact when the rotating guide rail i...
