Abstract: A connection assembly for articulated chains which comprise mutually-pivoted links that are split between at least one initial link and at least one terminal link. The assembly comprises transverse holes of the initial link and of the terminal link, which are arranged in mutual alignment when the initial and terminal links are in the coupling configuration; a master pin, with shape and dimensions substantially complementary to those of the holes and adapted to be inserted into those holes in order to couple the initial and terminal links; at least one elastic peg that can be accommodated, with elastic forcing thereof, in at least one respective radial channel which is defined, in its outermost parts, on at least one link chosen from between the initial link and the terminal link and, in its innermost part, on the master pin.

Abstract: An anti-galling method for treating materials, which provides for subjecting at least one of the at least two components mutually coupled with at least one degree of freedom, made of metallic material, to a first preliminary step of thermal treatments to increase surface hardness and to a second preliminary step of surface grinding. The method further includes the steps of: washing at least one portion of the surface of the at least one component subjected previously to the preliminary steps; shot peening the at least one portion of the surface of the at least one component previously subjected to washing; and applying a layer of molybdenum disulfide to the at least one portion of the at least one component previously subjected to shot peening.
