Definitions

  • the invention relates to a roller bearing, which comprises a sleeve with an inboard rim and an additional ring disk attached to the sleeve which, like the rim, is directed essentially radially inwards.
  • DE 101 23 965 B4 discloses a needle bearing whose outer ring, that is to say the sleeve, as in the case of DE 10 2014 203 828 A1, is provided with a radially inwardly directed rim only on one side.
  • the needle bearing according to DE 101 23 965 B4 on the side opposite the board, at least at one circumferential point, there is a radially outwardly curved tab against which a projection of an annular thrust washer, that is to say an annular washer, bears.
  • the tab and the projection are connected to each other by an attached cap.
  • the invention has for its object a rolling bearing, which has a sleeve as an outer ring with an inboard rim and an additional, disc attached to the sleeve has to be further developed compared to the prior art, in particular from the point of view of production and lubrication. Description of the invention
  • roller bearing with the features of claim 1.
  • the roller bearing comprises a sleeve which has a radially inwardly directed rim.
  • the rolling bearing comprises an annular disk which is held on the end face of the sleeve opposite the rim by a snap-in connection, the annular disk having a plurality of openings arranged distributed around its circumference.
  • locking means in particular in the form of a locking groove, are provided on one side of the sleeve, on which corresponding locking means of the annular disk are fixed.
  • the locking means of the ring disk are preferably designed as locking projections distributed around the circumference.
  • the openings in the ring disk allow lubricant, in particular oil, to flow through the ring disk.
  • lubricant in particular oil
  • coatings or other geometric or functional modifications are to be mentioned as possible modifications of the annular disk, that is to say of the cover, which improve the lubrication conditions. Such modifications can also help to reduce the friction between the rolling elements and the washer.
  • the rolling elements in particular rollers or needles, of the rolling bearing designed as a radial bearing roll off in the cylindrical section of the sleeve.
  • the openings which are in the washer are located in the radial direction with the cylindrical portion of the sleeve.
  • the imaginary cylinder which is described by the track of the sleeve, cuts through the openings in the ring disk.
  • a cylinder placed around all of the openings thus has a larger diameter than the cylinder given by the sleeve, in which the rolling elements roll.
  • a cylinder placed in the entirety of the perforations and tangent to each perforation preferably has a smaller diameter than the inner peripheral surface, that is to say the raceway, of the sleeve.
  • the openings in the annular disc can be designed, for example, as slot-shaped or circular openings.
  • the annular disk has at least six and at most thirty-six openings, for example twelve slot-shaped openings or twenty-four circular openings.
  • the rolling elements of the rolling bearing preferably have a cylindrical basic shape.
  • the rolling elements can be cylindrical rollers or needle rollers. It is also possible to design the rolling bearing as a tapered roller bearing.
  • the preferably cylindrical rolling elements can be guided in a cage.
  • This is designed, for example, as a window cage.
  • the window cage has two cage rings which are connected to one another by webs, pockets being formed between the webs for receiving a rolling element in each case.
  • One of the two cage rings is adjacent to the rim of the sleeve, in particular radially within the rim formed on the sleeve to form an annular gap.
  • the second cage ring is arranged close to the ring disk, which is connected to the sleeve by a snap connection.
  • This cage ring adjacent to the annular disc is preferably larger than the cage ring adjacent to the rim of the sleeve.
  • this applies both to a comparison between the outside diameters of the two cage rings and to a comparison between the inside diameters of the two cage rings.
  • the cage ring adjacent to the rim preferably has an outer diameter which is larger than the inner diameter of the cage ring which is adjacent to the ring washer, but is smaller than the outer diameter of the latter cage ring.
  • roller bearing designed according to the invention is explained in more detail below in two preferred embodiments with reference to the accompanying drawings. Show:
  • FIG. 1 shows a rolling bearing in an end view
  • FIG. 2 shows the roller bearing according to FIG. 1 in a sectional view
  • FIG. 3 shows an annular disk provided for connection to a sleeve of the rolling bearing according to FIG. 1, in a front view
  • FIG. 4 shows the annular disk according to FIG. 3 in a sectional view
  • FIG. 5 shows the annular disk according to FIG. 3 in a perspective view
  • FIG. 6 shows an alternative design of an annular disk provided for connection to a sleeve of the rolling bearing according to FIG. 1
  • FIG. 7 shows the annular disk according to FIG sectional view
  • FIG. 8 the ring disk according to FIG. 3 in a perspective view
  • a roller bearing identified overall by reference number 1
  • the roller bearing 1 has a sleeve 2 with a cylindrical section 3 and an adjoining, radially inwardly directed rim 4.
  • an annular disk 6 is connected to the sleeve 2 by means of a latching connection 5. In comparison to the sleeve 2, the washer 6 is much thinner.
  • the annular disc 6 manufactured as a sheet metal part has an annular section 7 which is arranged parallel to the flange 4 and thus lies in a plane which is oriented normal to the central axis of the rolling bearing 1. At the outer edge of the ring section 7 there is an edge section 8 which describes a short cylindrical shape.
  • a plurality of latching projections 9 are formed by the edge section 8, which engage in a latching groove 11 of the cylindrical section 3.
  • the locking groove 11 can be produced by cutting and / or forming processes.
  • cylindrical rollers as rolling elements 12.
  • the rolling elements 12 can run in the axial direction on the one hand on the flange 4 and on the other hand on the ring section 7 of the ring disk 6 connected to the sleeve 2 by means of the latching connection 5.
  • the inner circumferential surface of the cylindrical section 3 serving as a raceway for the rolling elements 12 describes a cylinder which intersects a plurality of recesses 10, that is to say openings, which are located in the ring section 7.
  • the rolling elements 12 are guided in a cage 13, which is made of plastic.
  • the cage 13 is a window cage with two cage rings 14, 15, which are arranged radially directly inside the ring section 7 or the flange 4.
  • the cage ring 14, which is adjacent to the washer 6, is larger than the cage ring 15, which is adjacent to the rim 4.
  • the recesses 10 are designed as slot-shaped openings 6 which are curved in accordance with the overall shape of the annular disk 6.
  • the annular disk 6 of the rolling bearing 1 according to FIG. 1 has twelve recesses 10.
  • the annular disk 6 shown in FIGS. 6 to 8 is also suitable for assembly with the sleeve 2, as illustrated in FIGS. 1 and 2.
  • the ring disk 6 has a total of twenty-four recesses 10, which are circular openings.
  • An outer cylinder can be placed around the entirety of the twenty-four recesses 10, which tangents each recess 10.
  • Another imaginary, inner cylinder lies within the annular space in which the recesses 10 are located and likewise affects all the recesses 10.
  • the cylindrical section 3 of the sleeve 2 has an inner diameter which is larger than the diameter of the inner cylinder and is smaller than the diameter of the outer cylinder. In this case, too, lubricant can be supplied to the rolling contacts of the rolling bearing 1 in a very short way through the annular disk 6.
  • Rolling bearings can be supplied to the rolling contacts of the rolling bearing 1 in a very short way through the annular disk 6.
