Abstract: An inner-support and gas-flotation static balancing device for a rotating ring-shaped part and a method of using the same are provided. A bottom end of an end cover is rotatably connected to a top end of a support base. One end, which is away from a working gas cavity, of the gas-flotation chamber is connected to a disc seat through a supporting column. The levelness of the gas-flotation chamber may be adjusted through the supporting column. Two axial positioning mechanisms are respectively mounted on two sides of the gas-flotation chamber in an axis direction. Gas supplied by external air supply may enter the working gas cavity, the cylindrical gas inlet channels, and the gas inlet holes through the gas supply hole, so as to form an gas film with certain bearing capacity between the working surface and the inner surface of the rotating ring-shaped part.

Abstract: The present disclosure provides a split-type swing angle adjustable aerostatic bearing device for rotor static balance and an air flotation support device for static balance of rotating ring-shaped parts, the split-type swing angle adjustable aerostatic bearing device for rotor static balance and an air flotation support device for static balance of rotating ring-shaped parts belong to a field of static balance detection, and aims to solve a problem of low measurement precision of rotor and realize static balance of rotating ring-shaped parts. A gas mold, having a certain bearing capacity, is formed between an outer surface of the air flotation support cover under the bearing base and a concave surface of the upper base, so that the bearing base is floated to realize an automatic centering of the rotor static balancing device.
