Axial stopper for cam shaft in computer numerical control milling machine, has borehole formed traverse to inner thread, and undercut reducing inner thread and arranged in traverse region of passage hole and screw-in opening

摘要

The stopper (1) has a borehole formed traverse to an inner thread (3), and an undercut (6) reducing the inner thread and arranged in a traverse region of a passage hole (4) and a screw-in opening (2). The undercut comprises a larger radial depth than threads of the internal thread. Diameter of the undercut is broader than diameter of the passage hole. The undercut is formed as right-angled with rounded corner and as a bevel. An outer annular groove (7) is provided at the axial stopper in an area of the traverse passage hole.
