Definitions

  • the invention relates to a cage for rolling bearings, which consists of a sprayable material.
  • the object of the invention is to create a cage principle which makes it possible to produce cages in one tool or in one and the same production run, which can be used for bearings of different diameters, ie large and small bearings, with the same and the same size rolling elements .
  • the aim is to design this cage principle in such a way that cages can also be formed which can be bent into a ring either in their plane or in the vertical direction thereto and which are ultimately also suitable for linear bearings.
  • the task is to use a tool set to also produce cages which are suitable for small or large identical bodies or for dissimilar rolling bodies.
  • the cage consists in one piece of an endless band which is injection molded in a single tool in a manner known per se, which has recesses for receiving rolling elements and which in the area of the recesses form one has a small part covering and protruding from the plane of the band holder for the rolling elements, which can be displaced by the rolling elements to be pressed.
  • the cage can be produced as an endless band and cut off in the appropriate length, and the rolling elements can be pressed in from at least one side in such a way that they are held on both sides.
  • the band can then either serve for a linear bearing or can be bent together to form ring bearings of large and small diameters.
  • the holders on their inside are preferably adapted to the contour of the rolling elements, so that they are already guided by the rolling elements.
  • the holders on one side of the cage strip can be displaced by the rolling elements to be pressed in, whereas the holders on the other side of the strip, which narrow the recess, are designed as continuous rigid edges, so that they Contour of the rolling elements adapted e .. result in an even better rolling element guidance.
  • good rolling element guidance ensures smooth rolling of the rolling elements, increases the load capacity and reduces bearing noise.
  • the relationship between material properties and strip thickness can be adapted to the respective application. If the Eand has a greater thickness, then thin points and / or slots can be provided in the webs between the cutouts, so that cage strips of this type can also be bent out of their plane to form a ring.
  • the cage band in its plane to form a ring band if the slots open outward in a wedge shape.
  • German PS 804 737 proposed to produce a cage for rolling elements from a plastic by pressing or casting.
  • the one- or two-part cage is made as a ring, so that if you put this proposal into practice, different tools would be required for each type of bearing and size.
  • This template is therefore not suitable for even solving the objects of the invention even approximately.
  • DE AS 1 shows that it is just as common in the plastics industry to manufacture complicated and endless parts (by the meter) in tools with sliders of all kinds. 198 990.
  • the procedure is such that part of a band or the like. pre-injected and the next part is injected in the same tool.
  • This DE-AS thus does not disclose a cage for - in the sense of this word - bearing, but rather a cage for sliding bodies, in which neither precision nor low noise are important.
  • the invention also opens up the possibility of producing different types of bearings in a basic tool by using different tools, and exchanging the matrix and patrix of one cage strip for another, so that, in particular in the case of smaller series, only some of the tools have to be replaced.
  • 1 is a cage belt for a ball bearing
  • FIG. 1a is a section along a-a of Fig. 1,
  • FIG. 1b shows a section according to b-b of FIG. 1,
  • FIG. 3 is a perspective view of the tape of FIG. 1st
  • All cage belts are manufactured by the meter so that the respective tool is not completely filled with sprayable material at the start of production, so that during the first spraying operation only about a part of the cage belt, for example four fifths of the tool length, is discharged for spraying. Precautions are taken to ensure that the rear part (fifth) in the production process remains below the required cage strip thickness so that the next spraying process is carried out on this strip. piece of molding compound can be sprayed on. Every further spraying process takes place after most of the finished sprayed strip part has been pushed out of the tool.
  • FIGS. 1 and 3 An endless ball bearing cage belt produced in this way is shown in FIGS. 1 and 3 in two different versions.
  • a cage strip 1 with only limited rolling element guidance is shown in FIGS. 1 a, 1 c and 3 and in FIG. 1 to the right end thereof. It has recesses as ball holders 10 and on both sides beyond its level and beyond the recesses, designed as elastic fingers 11 holders for the balls 2, which nevertheless provide sufficient support and a certain amount of guidance when the balls 2 are inserted while they are running the inner contour of which is adapted to the circumference of the sphere.
  • this cage strip 1 can be designed as shown in FIG. 1a and the associated part of FIG. 1.
  • the cage strip 1 is particularly suitable for linear bearings.
  • grooves 14 are provided in the webs 13, then it is also suitable for ring bearings because it can be bent out of its plane into a ring. In both cases, it is cut from the endless belt to the required length and either stretched inserted in the linear raceways or bent into a ring. In this case, the two opposing ends can be molded together in the tool itself.
  • the cage strip can have sufficient rigidity due to the appropriate choice of material and / or wall thickness.
  • FIGS. 2 and 2a show a cage strip produced in the same way, which is designed for cylindrical rollers, but is not limited to such rolling elements. In contrast to the example described above, it is designed in such a way that, although it is produced as a linear endless belt, it is bendable in its plane to form a ring.

Abstract

Une bande sans fin (1) pour cages de paliers à roulement de toutes sortes est produite par injection en tant que bande sans fin (1), coupée dans le sens de la longueur et peut être directement utilisée comme palier linéaire ou, après pliage, comme palier annulaire. L'avantage de cette bande réside dans le fait que l'on peut la façonner avec des logements, tels que des dispositifs de fixation, de préférence avec des glissières unilatérales (11) de guidage du corps du palier, et qu'elle s'adapte à des paliers de n'importe quelle grandeur. Pour renforcer la bande à cages, une rainure (15) peut recevoir un fil métallique (3), un ressort (30) ou un bourrage (31).
