Abstract
A method for aligning an armature shaft, wherein in a first step a concentricity error of the armature shaft is determined in the region of the shaft portion by measuring a radial deflection of the armature shaft, and wherein in a second step the radial deflection of the armature shaft is reduced by local deformation of the shaft portion on the side of the bearing element remote from the laminated portion.
Claims11
A method for aligning an armature shaft (10), wherein the armature shaft (10) comprises an armature (8) with a laminated portion (11) and a shaft portion (12) axially spaced apart from the laminated portion (11), wherein the shaft portion (12) has an output region (13), wherein a bearing element (4;
- 19) is fastened between the armature (8) and the output region (13), the method comprising:
- determining a concentricity error (a) of the armature shaft (10) in a region of the shaft portion (12) by measuring a radial deflection of the armature shaft (10);
- and
- reducing the radial deflection of the armature shaft (10) by local deformation of the shaft portion (12) on a side of the bearing element (4;
- 19) remote from the laminated portion (11),
- wherein the local deformation is produced by a mechanical deformation of the shaft portion (12) such that the geometry in the output region of the shaft is unaffected by the deformation.
