Positioning device and a method for producing the positioning device

A method for producing a positioning device, comprising:

• fixing a gearing, which has an output shaft and an output wheel non-rotationally fixed on the output shaft, in a housing having a first housing part, which has an integrally formed first bearing point of a bearing, and a second housing part, which has an integrally formed second bearing point of the bearing, in a manner such that the output shaft penetrates the second housing part, the output wheel is rotatably mounted in the bearing, an end face of the first bearing point interacts axially with a first bearing surface of the output wheel, and an end face of the second bearing point interacts axially with a second bearing surface of the output wheel located opposite the first bearing surface;
• arranging a permanent magnet of a rotary position detector on a gear wheel of the output shaft or on the output shaft at an end face of the output shaft, and a Hall sensor of the rotary position detector on the first housing part;
• welding the second housing part to the first housing part via an axial welded connection;
• and
• during welding, axially adjusting the second housing part and the first housing part relative to one another until a predetermined axial play is present in the bearing, the predetermined axial play being defined by a difference between an outer axial distance between the first and the second bearing points and an inner axial difference between the first and the second bearing surfaces.

A positioning device for mechanically actuating a component, comprising:

• a housing with a first housing part and a second housing part welded to one another via an axial welded connection, wherein the first housing part has an integrally formed first bearing point of a bearing and the second housing part has an integrally formed second bearing point of the bearing within the housing;
• a gearing fixed in the housing, the gearing having an output shaft penetrating the second housing part and that is drive-connectable with the component to be mechanically actuated outside the housing, and an output wheel that is non-rotationally fixed on the output shaft and rotatably mounted in the bearing;
• a rotary position detector with a permanent magnet and a Hall sensor, wherein the permanent magnet is 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 is arranged on the first housing part;
• wherein an end face of the first bearing point interacts axially with a first bearing surface of the output wheel, and an end face of the second bearing point interacts with a second bearing surface of the output wheel located opposite the first bearing surface;
• wherein the bearing has a predetermined axial play defined by a difference between an outer axial distance between the first and the second bearing points and an inner axial distance between the first and the second bearing surfaces;
• wherein at least one of the first bearing surface of the output wheel and an end face of the first bearing point facing the first bearing surface of the output wheel is annular;
• and
• wherein at least one of the second bearing surface of the output wheel and an end face of the bearing point facing the second bearing surface of the output wheel is annular.
