FIELD: machine building.
SUBSTANCE: invention relates to critical components used in engineering. Threaded connection unit of machine parts contains two connected parts, in the holes of which there is a pin with nuts. In one of the parts to be joined, the holes is made conical to fit with the tension of the conical part of the pin, the larger base of which is made to move to the plane of the connector. In another part, the hole is cylindrical. Pin is made with a belt that is installed in the cylindrical hole of the other part with a clearance and with the alignment of the lateral load due to the elastic deflection of the pin.
EFFECT: technical result consists in increasing the fatigue strength of the joint by reducing the bending stresses under the threaded part, increasing the uniformity of the distribution of transverse load in the group threaded connection, increasing the shear modulus of the unit.
