CONNECTION OF DETAILS OF MACHINES OF INCREASED STRENGTH Russian patent published in 2018 - IPC F16B5/02 

FIELD: machine building.

SUBSTANCE: proposed node belongs to the responsible compounds used in engineering. Machine parts joining unit comprising two connected elements: a stud with a head and a nut, cylindrical hole of a larger diameter than the threaded one adjacent to the plane of the connector and serving as a support for mounting a cylindrical portion of the stud having also a support end is formed in one connecting part, and in the other part, an opening is made with a portion in which the stud of the stud is installed with a compensation gap, to equalize the transverse load in the group threaded connection, due to the elastic deflection of the rod of the stud.

EFFECT: increase fatigue strength of the joint by reducing the bending stress under the threaded part, increasing the uniformity of the distribution of the transverse load in the group threaded connection, increasing the rigidity of the unit by shear.
