Abstract
A positioning device for mechanically actuating a component may include a housing with first and second housing parts welded to one another via an axial welded connection. The first and second housing parts may have integrally formed first and second bearing points, respectively, of a bearing within the housing. The positioning device may also include a gearing fixed in the housing, the gearing having an output shaft penetrating the second housing part and being drive-connectable with the component outside the housing, and an output wheel non-rotationally fixed on the output shaft and rotatably mounted in the bearing. The positioning device may further include a rotary position detector with a permanent magnet and a Hall sensor, the permanent magnet being arranged on a gear wheel of the output shaft or on the output shaft at an end face of the output shaft, and the Hall sensor being arranged on the first housing part. End faces of the first and second bearing points may interact axially with first and second bearing surfaces, respectively, of the output wheel located opposite each other. The bearing may have a predetermined axial play defined by a difference between an outer axial distance between the first and second bearing points and an inner axial distance between the first and second bearing surfaces.
