Abstract
The synchronized roller with freewheels includes a central body which exposes an outer cylindrical rolling surface provided to roll between two rolling tracks lined with a synchronizing unit, each end of the body presenting a smooth axis about which a synchronizing pinion is freely rotatable, the axis having a pinion axial stop unit which prevents the pinion from emerging from the pinion, while a roller axial guide bears on the central body and on the rolling tracks to keep the outer cylindrical rolling surface approximately centered on the tracks.
Claims15
A synchronized roller with freewheels comprising a central body which exposes an outer cylindrical rolling surface provided interposed between two rolling tracks on which it rolls simultaneously when said tracks move relative to each other, each said track being integrally lined with synchronization means which form a gear system with a synchronizing pinion located at each end of the central body, the synchronized roller comprising:
- a smooth axis of smaller diameter than that of the cylindrical rolling surface, arranged at each end of the central body, and around which the synchronizing pinion can rotate freely;
- pinion axial stop means integral with the smooth axis which bear directly or indirectly on said axis and bear directly or indirectly on the synchronizing pinion to prevent said pinion from emerging from said axis;
- roller axial guide means which bear directly or indirectly on the central body and directly or indirectly on at least one of the rolling tracks with which the cylindrical rolling surface cooperates in order to keep the latter approximately centered on said tracks.
