Abstract

The invention discloses an air floatation hanging type gravity unloading device for a space deployable mechanism. The air floatation hanging type gravity unloading device comprises an installation base plate and a top air floatation block, and a supporting rod and a guide rail connecting side plate are sequentially arranged above the installation base plate from left to right. A bottom base plate,a first bottom air floating block and a top base plate are sequentially arranged on the left side of the guide rail connecting side plate from bottom to top. Compared with an existing common air floating hanging type gravity unloading device, the air floating hanging type gravity unloading device for the space deployable mechanism adopts the air floating principle, low-damping movement of a deployable mechanism product is achieved, high damping of a mechanical bearing and various test failures caused by damage in use are avoided, the consistency of test precision is guaranteed, a linear air floatation sliding sleeve mechanism free of a side face surrounding mechanism is achieved, meanwhile, the thickness of a single linear mechanism is reduced, two-dimensional movement of a transverse airfloatation sliding block on a space plane is achieved, and a balance operation mechanism for an ultra-long-distance linear guide rail with a supporting mode is achieved.

Description

technical field [0001] The invention relates to the technical field of expandable mechanisms, in particular to an air-floating hanging gravity unloading device for a space expandable mechanism. Background technique [0002] As the size of the space deployment mechanism required by the spacecraft mission becomes larger and larger, the weight also becomes larger. For example, the length of some high-power solar wings after deployment exceeds 10 meters, and a single solar panel exceeds 10 kilograms. The weight of the veneer can reach several hundred kilograms. These weight changes lead to a significant increase in the frictional resistance of the microgravity simulation device using traditional mechanical bearings, which can no longer meet the ground deployment test requirements of this type of large-scale and high-weight space mechanism. [0003] The general air-floating hanging gravity unloading device adopts the microgravity simulation device for the deployment test of the t...
