THREADED CONNECTION OF PARTS Russian patent published in 2018 - IPC F16B5/02 

FIELD: machine building.

SUBSTANCE: invention relates to the field of machine building and can be used in connections of highly loaded elements. Threaded connection of the parts comprises a first part with a threaded hole, a second part with a through hole, a pin, a first spring, a second spring, a washer, a nut. In the first part and the second part, the coaxial holes are formed, the hole in the second part being a through hole and having a diameter larger than the diameter of the hole in the first part. Hole in the first part is threaded. Pin is installed in the holes of the first and second parts. One end of the pin is screwed into the hole of the first part, and a nut is screwed at the second end of the stud. Washer is installed between the nut and the second part. First spring and the second spring are coaxially installed in the through hole of the second part on the pin. Springs are made with the same pitch, wire diameter and different outer diameters, the first spring having a larger outer diameter than the outer diameter of the second spring. First spring is screwed into the second spring. Middle part of the pin, located in the through hole of the second part, is threadless.

EFFECT: technical result consists in increasing the strength of the threaded joint in the transverse direction and achieving self-centering of the parts to be connected with the pin.
