Abstract
A chain joint assembly includes a pin integral with at least one respective first chain link and a bushing, integral with at least one respective second chain link. The pin and the bushing are coaxial. The bushing has a constant inside diameter. At least one elastic ring is interposed between the pin and the bushing. The at least one elastic ring is substantially aligned with the portion of bushing which is coupled to a respective second chain link.
Claims13
A chain joint assembly comprises a pin integral with at least one respective first chain link, and a bushing, integral with at least one respective second chain link, said pin and said bushing being coaxial, wherein said bushing has a constant inside diameter, between said pin and said bushing there being interposed at least one elastic ring configured to take up thrust between the bushing and the pin and substantially aligned with a portion of said bushing which is coupled to a respective second chain link, wherein said pin comprises at least one respective region with reduced diameter for stable accommodation of said at least one elastic ring, said at least one respective region is aligned with the portion of said bushing coupled to the respective second chain link, wherein said at least one first chain link, at a surface thereof facing and proximate to said at least one second chain link, comprises at least one accommodation seat for at least one gasket.
A chain joint assembly comprises a pin integral with at least one respective first chain link, and a bushing, integral with at least one respective second chain link, said pin and said bushing being coaxial, wherein said bushing has a constant inside diameter, between said pin and said bushing there being interposed at least one elastic ring substantially aligned with a portion of said bushing which is coupled to a respective second chain link, wherein said pin comprises at least one respective region with reduced diameter for stable accommodation of said at least one elastic ring, said at least one respective region is aligned with the portion of said bushing coupled to the respective second chain link, wherein the bushing comprises a portion protruding externally with respect to the at least one elastic ring and defining an end tab, the at least one elastic ring being not in contact with the end tab of the bushing and being in contact with a central part of the bushing.
A chain joint assembly comprises a pin integral with at least one respective first chain link, and a bushing, integral with at least one respective second chain link, said pin and said bushing being coaxial, wherein said bushing has a constant inside diameter, between said pin and said bushing there being interposed at least one elastic ring substantially aligned with a portion of said bushing which is coupled to a respective second chain link, wherein said pin comprises at least one respective region with reduced diameter for stable accommodation of said at least one elastic ring, said at least one respective region is aligned with the portion of said bushing coupled to the respective second chain link, wherein an outer surface of the at least one elastic ring is substantially parallel to an inner surface of the at least one elastic ring.
