A gas turbulent bearing is a type of sliding bearing that utilizes gas as the lubricating medium. It relies on the properties of gas, such as its diffusivity, viscosity, and thermal conductivity, along with adsorption and compressibility, to create a stable air film between the moving parts. This air film provides load support and reduces friction through the combined effects of fluid dynamic pressure, static pressure, and squeezing action.
Gas bearings are typically categorized into three main types: gas dynamic pressure bearings, gas static pressure bearings, and gas squeeze film bearings. In practice, the operating conditions often involve a combination of these mechanisms—dynamic, static, and squeeze effects may all be present simultaneously.
One of the challenges in using gas bearings is their potential instability. Common issues include air hammer, oscillation, and eddy current instabilities. On the other hand, they can also suffer from sticking, where the shaft or rotor becomes immobilized due to the thinness of the gas film. The performance of these bearings is highly dependent on proper design, operation, and maintenance.
To ensure smooth and reliable operation, it's crucial to follow the recommended procedures and avoid any operational errors. Regular inspections and adherence to guidelines help prevent unexpected failures and extend the life of the bearing.
