5.2.3
Securing Screws with Wedge-
Locking washers
Wedge-Lock style bolt securing systems use geometry to
safely lock bolted joints in the most critical applications.
The key is the difference in angles. Since the cam angle
„α“ is larger than the thread pitch „α“, the pair of washers
expands more than the corresponding pitch of the thread.
Any attempt from the bolt/nut to rotate loose is blocked
by the wedge effect of the cams. When the pushed
movements of the equipment will get in contact with the
under surface of the securing plate, this surface contact
will secure the plate and prevents any motion in the axial
direction.
