2. Hydrodynamic thrust bearings

The simplest hydrodynamic system is the inclined plane or blochet used in thrust bearings. In the case of circular thrust bearings, the moving grain carried by the rotation shaft faces fixed or oscillating sectors. Let's take a look at these different cases.

2.1 Fixed-geometry inclined plane

The inclined plane is made up of two non-parallel flat surfaces (figure 7 ): the horizontal underside, which moves at translational speed U, and the upper surface, which is inclined at a very small angle α to the horizontal. The translational movement of the lower plate draws lubricant into the converging space, producing a pressure field that can support a load. It should be pointed out...
