Embodiment Construction

[0022] figure 1 A sectional view of a fluid pump 1 according to the invention is shown in a first exemplary embodiment. Here, the fluid pump 1 comprises a rotatable rotor 2 and a non-rotatable stator 3 . The rotor 2 is rotatably arranged within the stator 3 so as to be rotatable about an axis of rotation R within the stator 3 . Furthermore, the fluid pump 1 comprises an impeller 4 which is fixed to the rotor 2 in a non-rotatable manner. Figure 4 An enlarged cross-sectional view of the rotor 2 and the impeller 4 is shown. The impeller 4 comprises a plurality of blades 5 arranged axially between the support disk 6 and the central part 24 of the impeller 4 and the cover disk 7 . The rotor comprises a rotor housing 8 comprising a base 9 , a mounting sleeve 10 and a cover 11 . The base 9 and the cover 11 axially seal the mounting sleeve 10 in a fluid-tight manner. The cover 11 of the rotor housing 8 is formed by the support disc 6 of the impeller 4 , with the result that the ...

Abstract

The invention relates to a fluid pump, and the fluid pump includes an internal rotor rotatable about an axis of rotation and having a non-rotatable external stator and an impeller having multiple blades axially arranged between a support disc and a cover disc. The rotor has a rotor housing having a base, a mounting sleeve and a cover, in which an armature unit of the rotor is received so as to befluid-tight towards the outside. The support disc of the impeller forms the cover of the rotor housing and axially seals the mounting sleeve. The impeller includes a first part and a second part whichare fixed to one another in a material bonded manner. Here, the blades are exclusively formed integrally on the first part or on the second part, axially project from this part on one side and are axially covered by the respective other part.

Description

technical field [0001] The present invention relates to a fluid pump having a rotatable inner rotor and a non-rotatable outer stator. Background technique [0002] A general fluid pump is described, for example, in WO 2018 162 282 A1. It consists of a rotatable inner rotor and a non-rotatable outer stator. The rotor has a pot-shaped rotor housing in which an armature unit of the rotor is accommodated in a fluid-tight manner facing the outside. In addition, an impeller with a plurality of blades is arranged in the rotor housing, which is formed axially between the support disk and the cover disk. The impeller can be produced by injection molding. Disadvantageously, the choice of impeller geometry and material is limited by the manufacturing process. Therefore, optimization of the pumping behavior of the fluid pump is not easily achieved. Contents of the invention [0003] It is therefore the object of the present invention to propose an improved or at least an alternat...
