NUKE WITH REGULATOR OF TIGHTENING EFFECT AS A ROCATED RING

摘要

FIELD: machine engineering.;SUBSTANCE: in a nut with a tightening force regulator consisting of an internal threaded element and an external element with a hexagonal key surface with the possibility of joint screwing and unscrewing. The internal element with the thread is made as a spool with beads, on the cylindrical part of which, the external element with the surface for a hex wrench, made from the resilient frictional material in the form of a ring with the offset possibility relatively to the cylindrical part, is pressed. The external element has a groove in which a nut tightening force regulator is placed with a certain tightness, copying the lateral surfaces of the groove wall made with a wedge-shaped profile and lined metal washers into which the nut tightening force regulator abuts, the tension force regulator is made in the form of an elastic metal corrugated A ring fitted with interference that provides the necessary tightening torque of the nut.;EFFECT: higher reliability and durability of the nut.;1 dwg
