Lock nuts requiring a keyway
The locking principles
Lock washers, locking clips and locking plates are simple, stable and reliable fastening elements.
- Lock washers (fig. 3) engage a keyway in a shaft, or adapter sleeve thread. The washer locks the nut in position when one of the washer tabs is bent into one of the slots on the nut’s outside diameter (fig. 9).
- Locking plates (fig. 4) engage a keyway in a shaft or adapter sleeve and are attached to the side face of the nut by two bolts secured with locking wire. A locking plate consists of a plate, two hexagonal head bolts with drilled heads and lock wire to secure them (fig. 10).
- MS locking clips (fig. 7) engage a keyway in a shaft or adapter sleeve and one of the slots in the outside diameter of the lock nut. Locking clips are attached to the nut by a bolt (fig. 11).
