Abstract
Dans une cage massive fabriquée par enlèvement de copeaux et destinée à des rouleaux pourvus d'évidements frontaux, il est prévu, sur les bagues latérales 1, des saillies de retenue 3 qui sont arrondies dans la zone de la fonction de retenue afin de coopérer avec la surface circonférentielle de l'évidement pratiqué dans les rouleaux. Une surface 4 formant rampe s'étend de la surface circonférentielle 8 correspondante de la cage jusqu'à la face frontale 5 de la saillie de retenue afin de permettre une mise en place et un encliquetage aisés des rouleaux.In the massive cage produced by chip removal and intended for rollers provided with front recesses, there are provided, on the side rings 1, retaining projections 3 which are rounded in the area of the retaining function in order to cooperate with the circumferential surface of the recess in the rollers. A surface 4 forming a ramp extends from the corresponding circumferential surface 8 of the cage to the front face 5 of the retaining projection in order to allow easy positioning and snap-fastening of the rollers.
Description
CAGE MASSIVE POUR ROULEAUXMASSIVE CAGE FOR ROLLS
L'invention concerne une cage massive, réalisée par usinage, comprenant des bagues latérales, des flancs disposés entre lesdites bagues latérales, et des saillies de retenue qui prennent naissance sur les bagues latérales et s'engagent dans des évidements frontaux des rouleaux encliquetables. On connaît, du document DE 2 712 834, une cage dont les saillies de retenue sont déjà usinées dans leur forme définitive avant la mise en place des rouleaux La cage peut ainsi être de conception massive Un façonnage The invention relates to a massive cage, produced by machining, comprising lateral rings, flanks disposed between said lateral rings, and retaining projections which originate on the lateral rings and engage in front recesses of the snap-on rollers. Document DE 2 712 834 discloses a cage, the retaining projections of which are already machined in their final shape before the rollers are put in place. The cage can thus be of massive design.
ultérieur n'est pas nécessaire La cage connue est réali- subsequent is not necessary The known cage is reali-
sée, par exemple, en acier et peut donc être trempée Avec cette procédure, les rouleaux doivent être encliquetés, de sorte que les saillies de retenue doivent s'effacer élastiquement par l'intermédiaire des parties formant placed, for example, in steel and can therefore be hardened With this procedure, the rollers must be snapped in, so that the retaining projections must be elastically withdrawn via the parts forming
bagues latérales Les saillies ont une section transver- side rings The projections have a cross section
sale rectangulaire, ce qui pose souvent des problèmes lors de la mise en place des rouleaux En outre, dans certaines conditions d'exploitation, les arêtes des saillies raclent dirty rectangular, which often poses problems when placing the rollers In addition, under certain operating conditions, the edges of the projections scrape

Ceci provoque du bruit et modifie le fonctionnement après usure. En outre, dans la demande de brevet allemand 4 009 172 4, il est proposé d'employer, pour réaliser des This causes noise and changes the operation after wear. In addition, in German patent application 4,009,172 4, it is proposed to use, to achieve

Ce but est atteint par des parties de la surface latérale des saillies de retenue, lesdites parties étant This object is achieved by parts of the lateral surface of the retaining projections, said parts being
incurvées dans le sens circonférentiel des rouleaux et co- curved in the circumferential direction of the rollers and co-

On obtient ainsi des surfaces d'appui ou de contact exemptes d'arêtes, qui s'opposent à une usure prématurée, mais aussi à une production excessive de bruit La surface formant rampe est inclinée par rapport à la surface de contact de la bague latérale et se prolonge par la face frontale des saillies de retenue Le rouleau peut ainsi être introduit simplement et, grâce à l'élasticité des parties formant bagues latérales, il écarte les saillies This produces contact or contact surfaces free of edges, which prevent premature wear, but also excessive noise production. The ramp surface is inclined relative to the contact surface of the side ring. and is extended by the front face of the retaining projections The roller can thus be introduced simply and, thanks to the elasticity of the parts forming the lateral rings, it spreads the projections
