Abstract
A locknut which uses a pivotable segment mounted within the locknut body to slightly deflect producing an increased friction (locking force) between the locknut body and bolt which is threaded into the locknut body. This locking force is preset at the construction of the locknut to assume a lower amount of force or a higher amount of force according to the desires of the customer purchasing the locknut. The amount of force could be adjustable by using a set screw.
Claims8
A locknut comprising:
- a nut body having a first through opening which has a first series of screw threads, a slot formed within said nut body which connects with said first through opening;
- a shim which has a second through opening, said shim to be located within said slot, said second through opening having a second series of screw threads which matches said first series of screw threads;
- a ring segment having an inner screw threaded surface, said ring segment to be located within said second through opening, said ring segment being pivotable a limited amount producing deflection of said ring segment;
- and
- whereby when a bolt is threadably attached to said first through opening said bolt is to engage with said inner screw threaded surface of said ring segment producing a frictional locking force between said nut body and the bolt which prevents unauthorized disengagement of said nut body from the bolt.

A locknut comprising:
- a nut body having a first through opening, said first through opening having a central longitudinal axis;
- a slot formed in said nut body which connects with said first through opening;
- a shim which has a second through opening, said shim to be located within said slot, said second through opening aligns with said first through opening;
- a ring segment located within said second through opening, said ring segment being longitudinally deflectable;
- a set screw movably mounted in said nut body, said set screw being movable on an axis which is parallel to said central longitudinal axis;
- and
- when a bolt is mounted within said first through opening and connecting with said ring segment a frictional locking force is created due to the deflection of said ring segment.
