LOCKED THREADED JOINT Russian patent published in 2016 - IPC F16B39/34 

FIELD: construction.

SUBSTANCE: invention relates to fastening products and can be used in mechanisms, subjected to vibration, impact loads and thermal action. Invention is primarily intended for use in power machines and installations of car, aviation, machine building, railway and other industries. Locked threaded joint includes bolt (pin) with threaded rod, nut in contact along edge with washer made from deformable material. Nut has an annular groove, in which there are guides on internal and external circumferences of groove. Guides are equipped with stops. Guides are equal in height of depth of grooves and are movable. Ends of guides protrude beyond end of nut. Washer is arranged in groove and is made of brittle solid material.

EFFECT: technical effect is improved reliability of locking of threaded joint at impact loads of vibration and impact nature, including under conditions of thermal effect, due to increased area of contact in threaded joint between nut and part.
