Abstract

The invention discloses a radial gas bearing for an air suspension blower. The radial gas bearing comprises a top-layer foil, a top-layer gasket, a bottom-layer foil, a bottom-layer gasket, a bearing seat and a gasket, the top-layer foil is provided with a slit along the axial direction, two sides of the slit are provided with limiting blocks, the bearing seat and the gasket are respectively provided with a bearing seat limiting device and a gasket limiting device which are used for limiting the top-layer foil, and the bearing seat is provided with a bottom-layer foil fixing clamping groove which is used for fixing the bottom-layer foil and corresponds to the bottom-layer foil; a top-layer gasket is arranged above the bottom-layer foil, a bottom-layer gasket is arranged below the bottom-layer foil, the top-layer foil is located above the top-layer gasket, the bearing seat is provided with a top-layer foil fixing clamping groove corresponding to the top-layer foil, the top-layer foil is connected with the top-layer foil fixing clamping groove, and the top-layer foil fixing clamping groove coincides with one of the bottom-layer foil fixing clamping grooves; the free end of the bearing seat is provided with a gasket. The invention further discloses an assembly method. The bearing capacity is higher, the stability is high, and disassembly and assembly are convenient.

Description

technical field [0001] The invention relates to the technical field of dynamic pressure gas bearings, in particular to a radial gas bearing for an air suspension blower and an assembly method thereof. Background technique [0002] Air suspension centrifugal blower can be widely used in sewage treatment, food and drug industry, petrochemical industry, leather printing and dyeing industry, metallurgy and textile industry, cement building materials industry and thermal power generation industry, etc. Compared with traditional centrifugal fans, air suspension blowers equipped with gas bearings have advantages in terms of energy saving and high efficiency, oil-free maintenance, long-life semi-permanent, frequency conversion and low noise, and are currently the most advanced centrifugal fans in the industry. [0003] The existing radial gas bearings for air-suspension blowers have a low bearing capacity and cannot meet the support requirements for the rotors of high-power and high...
