CONNECTION OF MACHINE PARTS WITH INCREASED RIGIDITY Russian patent published in 2021 - IPC F16B2/06 F16B5/00 

FIELD: mechanical engineering.

SUBSTANCE: proposed threaded connection refers to the responsible connections used in mechanical engineering. In these connections, bolts are usually used, installed in the holes for fitting without a gap. The disadvantages of such a connection are the great technological difficulties associated with the need for joint boring of bolt holes in large connected parts, as well as the significant unevenness of the bolts’ work from the torque, which reduces the rigidity and strength of the connection. The goal of present invention is achieved by the fact that in the part to which the nut is adjacent, there is a section of a smaller diameter for installing a bolt with the recommended clearance, and in another connected part there is a hole of a larger diameter that passes to a hole of a smaller diameter in a section with a rounded surface concave to the axis of the bolt, which also has a rounded surface on this section.

EFFECT: increase the strength and rigidity of the joint.
