Hydrodynamic bearing for pumps for waste water etc. has rotor with blades around its axis and stator with semi-circular pockets open towards rotor blade sides

摘要

The bearing consists of rotor and stator. The rotor blades (3) are located around its axis. Several semi-cylindrical pockets (4) located on the inside of the stator have apertures directed towards the side of the rotor blades. The surfaces of two neighboring pockets form a rib (5). There is play between stator and rotor. The pockets are positioned in a ring shape like a ring groove. The play between the side wall of the rotor blade and the pocket side wall is of the same size or smaller, than the play between the stator rib and curved surface (6) of the rotor blade.
