Technology Background and Goals

Thrust bearings with adaptive geometry and surface texturing have emerged as a promising solution to enhance the performance of rotating machinery. The primary objective of this research is to develop advanced thrust bearings with dynamic surface features that can adapt to varying operating conditions, thereby improving load-carrying capacity, reducing friction, and prolonging service life.

This innovative approach combines adaptive geometry, which allows the bearing surface to deform and conform to the applied load, with surface texturing techniques that strategically introduce micro-features on the bearing surface. These micro-features can generate hydrodynamic effects, enhancing lubrication and load distribution. By integrating these two technologies, the thrust bearings can achieve superior performance, increased energy efficiency, and extended durability compared to conventional designs.
