摘要

The method for the production of a gear (3), comprises providing a gear housing (4) made of plastic with an opening, mounting a gear cover (12) made of plastic on the opening, and performing a friction welding between the gear housing and the gear cover so that the gear housing is locked. The gear comprises a drive connection (5) for the reception of a torque, where a contact force is exerted during the friction welding in axial direction between the gear cover and the gear housing, and the gear cover is exerted by a rotation around the axis of the drive connection. The method for the production of a gear (3), comprises providing a gear housing (4) from a plastic with an opening, mounting a gear cover (12) made of plastic on the opening, and performing a friction welding between the gear housing and the gear cover so that the gear housing is locked. The gear comprises a drive connection (5) for the reception of a torque, where a contact force is exerted during the friction welding in axial direction between the gear cover and the gear housing, and the gear cover is exerted by a rotation around the axis of the drive connection. The gear cover corresponds to a bearing shield of an electric motor. An independent claim is included for a gear unit.
