  • a rolling element cage serves to receive or retain the rolling bodies, for example needles, for which purpose corresponding pockets are formed on the cage into which the rolling bodies are inserted.
  • Known Wälz stresseskorfige can also be performed divided, so be provided with an axially extending slot, so that forms a parting line. That is, the rolling element cage is ultimately movable in the circumferential direction.
  • corresponding connecting means on the cages near the parting lines which are often also called a cage lock.
  • a recess is formed on a cage end and a corresponding engagement projection is formed on the other end, which engage in one another in the assembly position.
  • the geometry of the engagement projection as well as the recess is chosen so that a stable connection results, for example in the manner of a dovetail profile. If necessary, the connection also allows a certain axial mobility as well as a certain mobility in the circumferential direction. Since the WälzSkarfig is made of plastic, it is therefore sufficiently elastic, which allows easy closing of the separation point, so connecting the cage ends by mating.
  • the invention is thus based on the object of conceiving a split rolling element cage, which in contrast is improved and in which unintentional opening in the installed state or in operation is precluded. Description of the invention
  • corresponding protrusions are provided at least on one side of the guide rims, in the region of the first pocket following the respective lock side, which protrude in the radial direction of the respective guide board.
  • These projections act on the one hand stiffening, in particular, if they extend a bit far around the perimeter, so are elongated. However, they act in a path-limiting manner, that is to say that any torsional movement is limited by the fact that the projection (s) abuts adjacent components, for example an outer ring which engages around the rolling-element cage or the roller bearing and on which they are located in the pockets Rolling rolling elements, when the projections are arranged on the outside. In the case of an arrangement on the inside, the projections would, for example, abut the torsion on the outer surface of the shaft on which the rolling elements roll.
  • the projections are provided both on the outside and on the inside. This is useful so as to ensure a travel limit in each direction, usually after the guide rims, Seen radially, are substantially centered between the two pitch circles of the assembled rolling elements.
  • the projections extend expediently at least a little way in the circumferential direction, so they are elongated. Preferably, they extend at least over the length of the respective first pocket in the circumferential direction, so that a sufficiently long support distance is given. With sufficient strength, the projections can also be made shorter.
  • the outside of the projections should be bent, according to the shape of the surface on which it should strike, in order to realize the largest possible contact surface.
  • the radial height of the projections is preferably dimensioned such that their minimum distance to the outer or inner pitch circle of the recorded rolling elements is 0.01 mm. This means that they are almost as close as possible in the direction of the component to which they should strike in the event of torsional stress, so therefore only a very narrow gap between the abutment surfaces of the projections and this component, be it outer ring, be it shaft etc. remains. The narrower the gap, the lower the possible torsional motion.
  • the final realized gap size or the distance also depends on the size of the rolling element cage. For cages with small diameters in the range of a few centimeters, such small gaps are preferred, in contrast to significantly larger Wälz Eisenigen the gap may also be slightly larger, for example in the range of 0.1 mm or 1 mm or the like.
  • the individual projections themselves may be narrower than the guide rims, but they may also have the same width.
  • the specific width of the margin should be selected accordingly with regard to sufficient stability. Since the WälzMechkafig is made of plastic, the one-piece design of the projections, which are integrally formed on the guide rims, is particularly simple.
  • the WälzMechhimfig is produced by injection molding, so that the projections injection molding technology can be formed accordingly, even with the sufficient shape and size accuracy.
  • the projection and the recess itself preferably form a dovetail connection in the closed state.
  • You can, for example, have two opposing axial end faces, which, viewed in the circumferential direction, obliquely and substantially parallel to each other, such that the cage ends in the mounting position are limited axially and circumferentially movable. Even such an inherent mobility of the cage lock does not lead to an unwanted opening, since the torsion movement as described is largely or almost completely prevented via the projections.

  • corresponding projections 10a, 10b are provided both on the inside and on the outside, it would be conceivable, in principle, also to provide corresponding projections only on the inside or on the outside. Because even by the one-sided arrangement of such projections, the torsion of the cage ends 6, 7 is limited at least to some extent, so that the cage ends 6, 7 can not twist too far and this possible residual torsion is not sufficient to open the cage lock.

Abstract

L'invention concerne une cage (1) segmentée en matière synthétique pour éléments de roulement qui est constituée de deux bords de guidage (2) reliés par des nervures (3) en formant des poches individuelles (4) destinées à recevoir chacune un élément de roulement. La cage est fendue axialement en au moins un emplacement circonférentiel avec formation d'une ligne de séparation. Au moins un évidement est ménagé à une extrémité de la cage se raccordant à la ligne de séparation et au moins une saillie d'engagement correspondante, qui s'engage dans la position de montage dans l'évidement, est formée à l'autre extrémité de la cage. Selon l'invention, des saillies radiales (10a, 10b), s'étendant dans la direction périphérique, sont formées du côté extérieur ou intérieur au niveau des bords de guidage au moins dans la zone de la poche adjacente à la saillie d'engagement ou à l'évidement.
