Abstract

Perno folle con corpi volventi conici, comprendente un elemento cilindrico interno ed un elemento cilindrico esterno tra i quali è disposta almeno una pluralità di elementi volventi, in cui l'elemento cilindrico esterno è di grosso spessore e funge da mantello del perno folle, gli elementi cilindrici esterni ed interni presentano sedi affacciate tra loro per gli elementi volventi e sono dotati di elementi di tenuta alle loro estremità, nella quale gli elementi volventi della pluralità sono rulli conici e la superficie esterna dell'elemento cilindrico esterno presenta una gola perimetrale che é perpendicolare all'asse di rotazione del perno folle e che ha una sezione a trapezio isoscele.Idle pin with conical rolling elements, comprising an internal cylindrical element and an external cylindrical element between which at least a plurality of rolling elements are arranged, in which the external cylindrical element is very thick and acts as a mantle for the idle pin, the elements external and internal cylindrical have seats facing each other for the rolling elements and are equipped with sealing elements at their ends, in which the rolling elements of the plurality are conical rollers and the external surface of the external cylindrical element has a perimeter groove that is perpendicular to the rotation axis of the idle pin and which has an isosceles trapezoidal section.
