Abstract
An axial flux machine is provided having a housing in which a stator is provided that has a first and a second stator half, the stator halves being secured to the housing, and a rotor which is arranged between the stator halves and which contacts a rotor shaft in a rotationally fixed manner, the rotor shaft being rotatably mounted relative to the stator and the housing via bearing points. A separate adjusting element which adjusts the axial spacing between the rotor and the stator halves is arranged between at least one of the stator halves and the housing. An installation method for axially aligning the assemblies relative to one another is also provided.
Claims16
An axial flux machine, comprising:
- a housing;
- a stator located in the housing, the stator having a first stator half and a second stator half, the first and second stator halves are fastened to the housing;
- a rotor arranged between the first and second stator halves and non-rotatably connected to a rotor shaft which is rotatably mounted relative to the stator and the housing via bearing points;
- a separate adjusting element, which adjusts an axial spacing between the rotor and the first and second stator halves, arranged between at least one of the first or second stator halves and the housing;
- and
- a further adjusting element is arranged between the rotor and the rotor shaft or at one said bearing point between the rotor shaft and the housing, wherein the adjusting elements are comprised of several sub-elements stacked on top of one another in order to adjust a required adjustment dimension by a combination of a plurality of the sub-elements.
An installation method for axially aligning a first assembly comprising a housing and a bearing, a second assembly comprising a first output-side stator half, a third assembly comprising a rotor and a rotor shaft, and a fourth assembly comprising a second stator half, relative to one another, comprising the following steps:
- determining axial actual distances on surfaces of the first assembly, the second assembly, and the third assembly;
- comparing the actual distances that are determined with specified target distances;
- determining deviations of the actual distances from the respective target distances;
- and
- calculating a thickness therefrom for a separate adjusting element between the surfaces of the first output-side stator half and the housing.
An axial flux machine, comprising:
- a housing;
- a stator located in the housing, the stator having a first stator half and a second stator half;
- a rotor arranged between the first and second stator halves and non-rotatably connected to a rotor shaft which is rotatably mounted relative to the stator and the housing;
- and
- a separate adjusting element, which adjusts an axial spacing between the rotor and at least one of the first or second stator halves, arranged between the at least one of the first or second stator halves and the housing;
- wherein there are a plurality of the adjusting elements with different thicknesses distributed around a circumference of the axial flux machine.
