Abstract
A method for producing a cam phaser for a cam shaft of an internal combustion engine, the cam phaser including a rotor, a stator and at least one cover, the method including arranging the at least one cover at the stator; and welding the at least one cover with the stator, wherein a first weld, a second weld and a third weld are formed at least on a large radius or on a small radius during the welding, and wherein the small radius is smaller than the large radius. The invention furthermore relates to a cam phaser for a cam shaft of an internal combustion engine, the cam phaser including a rotor; a stator and at least one cover.
Claims3
A method for producing a cam phaser for a cam shaft of an internal combustion engine, the cam phaser including a rotor, a stator and at least one cover, the method comprising:
- arranging the at least one cover at the stator;
- and
- welding the at least one cover with the stator,
- wherein a first weld, a second weld and a third weld are formed on a large radius and on a small radius during the welding,
- wherein the small radius is smaller than the large radius,
- wherein the second weld is formed on the large radius and the third weld is formed on the small radius,
- wherein the third weld on the small radius is arranged and attached at a radially inward extending vane of the stator,
- wherein a borehole is arranged in the radially inward extending vane of the stator, and
- wherein the third weld is formed on the small radius closer to a rotation axis of the rotor than the borehole.
