Method for mounting a decoupling element in a through-hole in a stator of an electric machine, stator for an electric machine, and electric machine comprising a stator of this type

A stator for an electric machine, comprising:

• a plurality of through-holes, each configured to receive a fastening screw for connecting the stator to a housing therein in a mounted position of the stator;
• and
• a corresponding plurality of decoupling elements accommodated in the plurality of through-holes, each of the plurality of decoupling elements comprising:
• a sleeve that, in the mounted position of the stator, is supported axially on the housing and on which a head of the fastening screw is supported opposite the housing;
• and
• a sheath which surrounds the sleeve and which is made of an elastic material, wherein, in the mounted position of the stator, the stator is vibrationally decoupled from the housing via the sheath and the elastic material of the sheath rests directly against an inside wall of the through-hole.

An electric machine, comprising:

• a housing that includes a plurality of internally threaded holes;
• a stator that includes a corresponding plurality of through-holes that are respectively aligned with the plurality of internally threaded holes;
• a plurality of dampening elements respectively accommodated in the plurality of through-holes of the stator, each of the dampening elements comprising:
• a sleeve that includes a first axial end that abuts the housing and a second axial end opposite the first axial end;
• and
• a sheath that extends about the sleeve, the sheath being formed of elastic material;
• and
• a corresponding plurality of fasteners extending respectively within the sleeves of the plurality of dampening elements through the corresponding through-holes of the stator and into the internally threaded holes of the housing to mount the stator to the housing, each having a head that abuts the second axial end of the sleeve of the corresponding dampening element, wherein the elastic material of each sheath extends between the sleeve and the corresponding through-hole and rests directly against an inside wall of the through-hole, such that vibrations from the housing are dampened by the elastic material before reaching the stator.
