摘要

The gear construction structure (1) has an outer toothing (3) that is provided with several teeth (4). A height of each tooth is increased and decreased along tooth width. The gear construction structure is rotated along central axis of rotational symmetry (8). A curve of addendum is extended along tooth width, and each tooth has tooth engaging portion that is not arranged parallel to central axis of rotation symmetry.
