Description

Technical Field

[0001] The utility model relates to the technical field of air-floating guide rails, in particular to a stable air-floating guide rail. Background Art

[0002] A stable air-floating guideway is a guideway system that uses the principles of gas dynamics to achieve suspension motion. It is usually composed of a guideway, a suspension unit, and a control system. There are usually many air holes on the guideway, through which gas is supplied to the suspension unit. There is an air bag or air cushion inside the suspension unit. When the gas is ejected from the guideway, the airflow generated supports the suspension unit and makes it float above the guideway. This guideway system is usually used in maglev trains, high-speed maglev transportation systems, laboratory equipment and other fields, providing convenience and efficiency for people's travel and work.
