Screw lock for use in e.g. aircraft industry, has locking screw screwed into nut, and bolt's front surface screwed against outer surface of wedge plate so that package of wedge plates is pressed against front surface of bolt

摘要

The lock (1) has wedge plates (4-6) lying on each other, where a wedge tooth is provided on a contact surface of the wedge plates. The tooth has an elevation angle that is larger than an elevation angle of threads of a bolt (17). A locking screw (7) is screwed into a nut (2) on a side turned away from the bolt, and an axial groove is formed inside the nut. A front surface of the bolt is screwed against an outer surface of the wedge plate (5) so that a package (3) of the wedge plates is pressed against the front surface of the bolt.
