Patent ID: 7791000

Claim:
A method for securing a rotational symmetrical part to a hub part along an axial direction (O), wherein the rotational symmetrical part comprises (1) a contact surface which defines an opening into which the hub part is inserted along an axial direction (O), and (2) a functional surface comprising a functional surface, and the hub comprises a contact surface, the method comprising the steps of: inserting the hub part into the opening of the rotational symmetrical part wherein the contact surface of the hub part engages the contact surface of the rotational symmetrical part in an interference fit to produce an angular deviation of the functional surface from a first position to a second position; and welding the hub part to the rotational symmetrical part at a point of contact of the contact surface of the hub part and the contact surface of the rotational symmetrical part to produce an angular deviation of the functional surface from the second position to the first position.
