Abstract
A bearing assembly may be provided for mounting a rotor which can be rotated about a rotational axis. In particular, for a rotary fluid pump or rotary blood pump comprising: a main body, a bearing element which can be displaced relative to the main body in the direction of the rotational axis for receiving the rotor, and an adjusting device which is connected to the bearing element for displacing the bearing element in the direction of the rotational axis by a predefined distance, wherein the predefined distance is <=500 micrometres.
Claims20
A bearing assembly for mounting a rotor within a pump housing of a rotary blood pump, the rotor being rotatable about a rotation axis, the bearing assembly comprising:
- a base body;
- a bearing element, which is displaceable relative to the base body in the direction of the rotation axis, for accommodating the rotor;
- and
- an adjusting device, which is connected to the bearing element, for displacing the bearing element in the direction of the rotation axis by a predetermined distance, the predetermined distance being ≤500 μm, wherein the adjusting device is configured to be situated so as to be operable from outside of the pump housing after installation of the bearing assembly.
A rotary fluid pump for conveying blood, comprising:
- a pump housing;
- a bearing assembly for mounting a rotor rotatable about a rotation axis within the pump housing;
- a base body;
- a bearing element, the bearing element being displaceable relative to the base body in the direction of the rotation axis, including the rotor;
- and
- an adjusting device, the adjusting device connected to the bearing element for displacing the bearing element in the direction of the rotation axis by a predetermined distance ≤500 μm, wherein the adjusting device is situated so as to be operable from outside of the pump housing after installation of the bearing assembly.
