Patent attributes
The invention relates to a hydrodynamic sliding bearing of a shaft (2), in particular of a magnetic coupling pump (1), wherein the hydrodynamic sliding bearing (4) comprises a clamping sleeve (7) disposed between bearing sleeves (6), wherein the bearing sleeves (6) are each mounted with their bearing front side (8) on an axial bearing element (9). The hydrodynamic sliding bearing (4) is characterized in that the bearing sleeve (6) and the clamping sleeve (7) have on their respective front sides (11, 12) a respectively correspondingly designed spherical region (18, 19) which intermesh, wherein the clamping sleeve (7) has at least one concentric groove (28, 29, 31) and wherein the axial bearing element (9) has a recess (42) adapted to the bearing front side (8) of the bearing sleeve (6).
