Abstract
Hydrodynamic plane thrust bearing (26) for a generator (10), preferably operable with a water turbine, with a rotor (12), a track ring (30) rotating with the shaft (20) of the rotor (12), and a bearing segment (32) not rotating with the shaft (20) of the rotor (12) and supported on a bearing housing (24), characterized in that the track ring (30) substantially consists of a plastic matrix with reinforcing fibers embedded therein.
Claims6
A hydrodynamic plane thrust bearing for a generator operable by means of a water turbine, comprising:
- a rotor having a shaft;
- a track ring rotating with the shaft of the rotor;
- a bearing housing;
- and
- at least one bearing segment not rotating with the shaft of the rotor and supported on the bearing housing;
- wherein the track ring comprises a plastic matrix with reinforcing fibers embedded in the matrix, and comprises a laminate of at least four layers of fiber-reinforced plastic, the fibers in each layer being unidirectionally aligned and the angle of the fiber alignment of the layers being between 0° and 90°.
