Abstract: 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).

Abstract: A method for mounting a hydrodynamic sliding bearing of a shaft, in particular a magnetic coupling pump, wherein the hydrodynamic sliding bearing includes a bearing bushing disposed between a bearing sleeve and a bearing housing includes the steps of A coating a clamping ring on at least one of its surfaces with a friction-increasing coating, B heating the clamping ring and applying to the bearing bushing so that a pre-assembly unit is formed, and C heating the bearing housing, wherein the pre-assembly unit is inserted in the bearing housing. A double pressure bond is thus advantageously provided where a radial prevention of rotation and an axial prevention of displacement is achieved without any axial pinning as prevention from rotation and axial tensioning (e.g. L-profile ring) of the bearing bushing being required.

Abstract: A magnetic coupling includes an inner rotor and an outer rotor between which a split case is disposed. The split case has a flange which can be fixed with a counter-flange on a coupling component. The split case is made of a ceramic, whereas the coupling component and the counter-flange are formed from a metal material. Provided on the flange is a spherical elevation which engages in a corresponding, spherical indentation. A compensating element is arranged between the flange and the counter-flange and can have a spherical indentation corresponding to the spherical elevation on one of its front sides.
