Abstract

Procedure for practicing roller or needle retention means in integral bearing boxes for the aforementioned type, by means of reinforcement of material obtained in the sleepers and characterized by the fact that it consists in acting on limited and predisposed areas of each sleeper ( 10) with symmetrical forces two to two with respect to the sleeper, located in a plane that passes through the axis of the box and incident on said axis, being such the intensity of these forces that locally causes, in the action zones, unitary tensions that exceed the load in the elastic limit of the material constituting the box, and being such the direction of said forces that proportions radial components with respect to the box, incapable of deforming the sleepers outside the limited and predisposed areas where the forces in question act .
