CONNECTION OF PARTS Russian patent published in 2025 - IPC F16C11/04 

FIELD: mechanical engineering.

SUBSTANCE: connection of parts includes connected links in the form of an enveloping and enveloped lugs with holes, a shaft, side bushings, an antifriction bushing and a toothed spring-loaded locking mechanism. Shaped shaft has two taper sections and outer splined surface to axially displace therein. Locking mechanism is made in the form of two pairs of half-gears connected with tightening springs. Each pair of half-gears inner cylindrical splined surface is mating shaft conical sections splined surface, and outer cylindrical toothed surface is reciprocal to toothed sectors on female and male lugs with possibility of their jamming – locking during movement of shaft and its conical sections in direction from top to base.

EFFECT: guaranteed jamming of an enveloping lug relative to the enveloped lug and improving reliable fixation of connected links at high loads.
