Description

Technical Field

[0001] This invention belongs to the field of gas bearings, specifically relating to a foil thrust air bearing with a structure that mimics the pores and muscles of a whale. Background Technology

[0002] Foil thrust air bearings are widely used as key components in various precision measuring instruments and confidential equipment, capable of bearing axial loads and ensuring stable support and operation of the shaft system. However, traditional types have limitations: their air supply system is fixed, making it difficult to adapt to different working conditions, and the stability of the air film is affected; their load-bearing capacity is limited, restricting the development of precision equipment towards higher loads.

[0003] Bionics offers new insights into problem-solving. The corrugated structure of a whale-like blowhole muscle, made of rubber, allows for adjustment of its expansion by controlling the air intake. Combining this with foil thrust bearings promises to precisely regulate air supply, optimize the air film, improve load-bearing capacity, expand the application range of foil thrust bearings, and meet the demands of modern industry. Summary of the Invention

[0004] The purpose of this invention is to provide a foil-type thrust air bearing that mimics the muscle structure of a whale's blowhole. By utilizing the characteristics of this whale-like muscle structure, the stiffness of the foil body is controlled through the degree of expansion, effectively coping with high-load impacts and expanding the applicable scenarios for the foil thrust bearing. Simultaneously, by controlling the expansion of two cooperating foil bodies, the entry of external high-pressure gas into the bearing clearance can be partially or completely prevented, allowing independent control of the air supply volume of each air supply hole, thus enabling the foil thrust bearing to adapt to more diverse air supply scenarios.

[0005] To achieve the purpose of this invention, the following technical solution is proposed: a foil-type thrust air bearing mimicking the structure of whale spiracles and muscles, comprising: a bearing base (1), a corrugated foil structure resembling whale spiracles and muscles (2), and a flat foil sheet (3). The bearing base (1) includes an "L"-shaped mounting groove (1-1), an air supply hole I (1-2), an air supply hole II (1-3), a boss (1-4), and a magnetic strip (1-5). The corrugated foil structure resembling whale spiracles and muscles (2) includes a magnetic base (2-1), a corrugated foil structure air inlet duct (2-2), and a corrugated foil body (2-3). The flat foil sheet (3) includes a foil plane (3-1) and a foil clip (3-2). The characteristic feature is that the "L"-shaped mounting groove (1-1) and the boss (1-4) The air supply holes I (1-2) are evenly distributed circumferentially on the bearing base (1), the air supply holes II (1-3) are evenly distributed radially on both sides of the air supply holes I (1-2), the magnetic strip (1-5) is located at the outlet of the air supply hole II (1-3), the corrugated foil structure (2) resembling whale spiracle muscle is located on the bearing base (1), the corrugated foil structure air inlet duct (2-2) is installed in the air supply hole II (1-3), the magnetic base (2-1) is located at the bottom of the corrugated foil structure (2) resembling whale spiracle muscle and cooperates with the magnetic strip (1-5), the flat foil (3) is located on the corrugated foil body (2-3), and the foil buckle (3-2) is installed in the "L" shaped mounting groove (1-1).

[0006] Furthermore, the bearing base (1) and flat foil (3) are made of alloy material, the wave foil structure (2) resembling whale spiracles and muscles is made of rubber material, and the magnetic strip (1-5) and magnetic base (2-1) are made of magnetic material.

[0007] Furthermore, the corrugated foil (2-3) is shaped like a yin-yang fish, and in the expanded state, the two corrugated foils fit together tightly with a smooth curve to block the air from the air supply hole I (1-2).

[0008] This invention provides a foil thrust air bearing with a structure mimicking the spiracle muscle of a whale. It innovatively draws inspiration from the role of whale spiracle muscle in air passages and incorporates the yin-yang symbol from traditional Chinese culture to construct a unique air passage network within the bearing. By controlling the gas flow rate in the inlet duct (2-2) of the foil structure, the expansion degree of the foil body (2-3) can be effectively controlled, thus altering its stiffness. By simultaneously controlling the expansion of two cooperating foil bodies (2-3), the gas flow rate at air supply port I (1-2) can be precisely adjusted to control the gas film thickness. Furthermore, the gas flow rate at each air supply port I (1-2) can be independently controlled, ensuring a stable gas film thickness for the foil thrust air bearing. Compared to traditional foil thrust bearings, it can dynamically adjust its load-bearing performance based on real-time operating conditions, improving the bearing's stability and adaptability, and expanding the applicable scenarios for foil thrust bearings.
