Abstract

Una gabbia di trattenimento per rulli conici del tipo composto da una corona circolare interna (11) e una corona circolare esterna (12), sostanzialmente parallela alla prima e unita ad essa tramite una serie di nervature trasversali (13), è dotata di incavi o tasche laterali (16) ricavate nella parte inferiore delle nervature (13), dai due lati opposti di esse, e di una serie di aperture trasversali (18) ricavate nella superficie circonferenziale inferiore (9) della corona circolare interna (11) della gabbia (10), nel tratti di essa compresi tra due nervature (13) adiacenti.A retaining cage for conical rollers of the type consisting of an internal circular crown (11) and an external circular crown (12), substantially parallel to the first and joined to it by a series of transverse ribs (13), is provided with recesses or side pockets (16) made in the lower part of the ribs (13), on the two opposite sides of them, and of a series of transverse openings (18) made in the lower circumferential surface (9) of the internal circular crown (11) of the cage ( 10), in the portions of it comprised between two adjacent ribs (13).
