CONNECTION OF MACHINE PARTS Russian patent published in 2020 - IPC F16B5/02 

FIELD: machine building.

SUBSTANCE: invention relates to critical compounds used in hydraulic machine building at connection of hydroelectric unit shafts. Set goal is achieved by the fact that threaded connection of shafts of hydraulic machines, comprising two connected parts in holes of which there is a pin with nuts, also in one connected part there is a hole of larger diameter, for installation of stud support part, passing to smaller diameter and adjoining to split plane, and in other connected part stud has section with larger diameter, to provide recommended radial clearance.

EFFECT: invention objective is to increase strength and rigidity of connection by reducing bending stresses under threaded part, to increase uniformity of transverse load distribution in group threaded joint.
