2.Material and Method
The bearings used in turbine-generator units of hydroelectric power
plants are called sliding bearing. Sliding bearings are divided into
hydrodynamic and hydrostatic. The hydrodynamic bed oil film is formed
spontaneously. On the hydrostatic bed, an oil pump from the outside
supports the bearing oil. The bearing shells work together with the
bearing pad. The oil film formed between the bearing shell and the
bearing pad has very large radial or axial loads depending on the
position of the rotating mass. Figure 1 is a schematic view of the
bearings in the Francis turbine of a hydropower plant with a vertical
shaft.
