Abstract

Una gabbia di trattenimento dei rulli per cuscinetti a rulli conici, del tipo costituito da una corona circolare interna (11), una corona circolare esterna (12) e da una raggiera di nervature (14) di distanziamento dei rulli (17) e di collegamento tra le due corone, prevede che dette corone circolari (11, 12) siano dotate di bordi cilindrici (8, 9) che poggiano interamente su rispettive superfici (15, 16) dell'anello interno (13) del cuscinetto; dette nervature (14) sono dotate ognuna di una coppia di alette superiori (20), divergenti verso l'alto ed elasticamente cedevoli.A roller retaining cage for tapered roller bearings, of the type consisting of an internal circular crown (11), an external circular crown (12) and a radial rib (14) for spacing the rollers (17) and connecting between the two crowns, it requires that said circular crowns (11, 12) have cylindrical edges (8, 9) which rest entirely on respective surfaces (15, 16) of the inner ring (13) of the bearing; said ribs (14) are each equipped with a pair of upper fins (20), diverging upwards and elastically yielding.
