Definitions

  • the invention relates to a rolling bearing according to the preamble of claim 1.
  • roller bearings or cages for such roller bearings are, for example, from DT-C3-14 00 324, DE-A1-31 34 241, DE-C2-34 24 741, DE-A1-44 42 269, DE-A1-196 19th 712, DE-A1 -196 54 584, EP-B1 -0 225 508 and EP-A1-0 392 146.
  • the object of the invention is to provide a rolling bearing of the type mentioned, in which the packing density of the rollers is high and which is easy to assemble.
  • the invention is implemented in any case if it is a bearing which essentially consists of three different parts and a plurality of rollers.
  • the rollers are located between an outer and an inner ring and are separated by the cage.
  • the special feature of the cage is that it consists of two cage rings with different diameters and webs, which are regularly wedge-shaped and ensure that the rollers are arranged at a minimum distance from each other.
  • annular recesses or flanges are regularly provided, which ensure that the cage is preferably accommodated in a form-fitting manner within the rings. At the same time, this also ensures that the cage can be inserted between the two rings in the axial direction, but cannot be passed through.
  • the packing density of the rolls can thus be made greater than in known roll bearings, so that larger forces can be transmitted.
  • the assembly of the roller bearing can be carried out in such a way that the inner ring of the roller bearing, which is pushed onto a machine shaft, is fitted with rollers from an annular magazine, the rollers being held by grease.
  • the shaft with the inner ring and the rollers is then inserted into the outer ring fitted with the cage.
  • the cage can be fixed in any way on the outer ring and the wedge-shaped webs can be arranged between the rollers. The small contact surfaces that the rollers have with the wedge side surface pieces of the cage minimize the friction of the rollers with the cage.
  • the running surfaces in which the roller bearings are guided can of course also be formed in the outer ring itself, that is to say not on the inner ring, so that the cage is modified accordingly and is mounted on the inner ring.
  • the various embodiments of the invention therefore have in common that the cage serves to separate the regularly cylindrical rolling elements, is mounted in the outer or inner ring of the bearing and can be inserted in the axial direction of the bearing.
  • a particularly advantageous embodiment of the invention provides that the outer and inner diameters of the cage rings are adapted to the inner and outer diameters of the rings, taking into account the outer diameter of the rollers.
  • Another expedient embodiment of the invention provides that the ring flanges are directed towards the axes of the rollers. These measures ensure that the rollers are guided either through one or the other cage ring or through both together.
  • an expedient embodiment of the invention provides that the webs are designed as projections, which preferably have an essentially trapezoidal or triangular cross section.
  • the webs have wedge-side surface pieces. This ensures on the one hand a stability of the cage and on the other hand also ensures that the distance between two adjacent rollers can be kept to a minimum.
  • the width of the webs in the area of the wedge side surface pieces is selected such that the distance between the rollers is different
  • the distance between the rollers is preferably only a few tenths of a millimeter.
  • Another embodiment of the invention is such that the outer ring has a lateral, annular recess into which the cage ring having the larger inner diameter is fitted in a form-fitting manner.
  • a roller bearing is preferably suitable as a double bearing, in which the sides of two outer rings provided with the recesses touch one another.
  • the fitting can preferably also be an interference fit.
  • the advantages achieved by the invention are, in particular, that the proposed bearing can be used not only for centric, but also for eccentric bearings of shafts and components.
  • additional forces occur, which places particular stress on both the bearing itself and the cage.
  • the cage is guided radially on the rollers and is therefore excessively loaded by the rollers when it is eccentrically supported.
  • the cage is guided on the outer ring and / or on the inner rig, as a result of which the cage can be used advantageously, in particular when components are eccentrically supported.
  • the cage is subjected to additional forces from the rolling bearing not overused.
  • the design of the cage does not have to be particularly robust. At the same time, a particularly advantageous assembly of the cage is possible.
  • the cage according to the invention allows a particularly small width of the rolling bearing, because the cross section of the cage rings can be narrow.
  • the cage rings can be sufficiently high because there is enough space in the radial direction for their cross-sectional height.
  • the primary task of the cage is to separate the roles, while at the same time ensuring an even distribution of the roles over the circumference of their career.
  • the cage is regularly made of plastic and can be manufactured by spraying.
  • FIG. 3 shows another radial section through the assembled roller bearing according to FIG. 1,
  • FIG. 4 is an axial plan view of the cage shown in FIG. 1 with a peripheral partial section VI, 5 shows a section through the cage along the line VV in Fig. 4,
  • FIG. 8 is a reduced perspective view of the cage shown in FIG. 4,
  • FIG. 11 shows an axial top view of the cage shown in FIG. 9 with a peripheral partial section XIII,
  • FIG. 15 is a reduced perspective view of the cage shown in FIG. 9, 16 shows a radial section through the assembled roller bearing according to a third exemplary embodiment
  • FIG. 18 shows an axial top view of the cage shown in FIG. 17 with a peripheral partial section XX,
  • Fig. 19 shows a section through the cage along the line XIX - XIX
  • FIG. 22 is a reduced perspective view of the cage shown in FIG. 16,
  • Fig. 28 is an enlargement of the detail XXVIII of Fig. 29 and
  • Fig. 29 is a reduced perspective view of the cage shown in Fig. 23.
  • 1 consists of an inner ring 10, a set of cylindrical rollers 12, a cage 100 and an outer ring 30 and is rotatably supported about the axis 40a.
  • the inner ring 10 is provided at its axial ends with an annular flange 10b or 10c, which delimit a running surface 10a for the rollers 12.
  • the rollers 12 are secured against axial displacement by the ring flanges 10b, 10c.
  • the distance A of the rollers 12 from one another in the inserted state in the inner ring 10 is preferably approximately 0.1 mm.
  • the rollers 12 can, for example, be inserted into the inner ring 10 from an annular magazine (not shown) with grease.
  • the axial length of the rollers 12 corresponds approximately to the distance between the ring flanges 10b and 10c.
  • the cage 100 has a front cage ring 102, a rear cage ring 101 and a number of webs 104 corresponding to the number of rollers 12, which extend transversely between the cage rings 1 01, 102 and are evenly distributed over the circumference of the cage 100.
  • the webs 104 are wedge-shaped in cross section, here trapezoidal, as shown in particular in FIGS. 4 and 6. In general, the webs are designed so that they taper towards the axes 12c of the rollers 12.
  • the webs 104 as is most clearly shown in FIG. 7, have wedge-side surface pieces 104a and 104b each formed as projections at their ends, with respect to which middle wedge-side surface pieces 104c are offset inwards.
  • the wedge side surface pieces 104a, 104b serve to guide the rollers 1 2, while the wedge side surface pieces 1 04c do not touch the rollers 1 2.
  • the contact areas of the webs 104 with the rollers 1 2 are therefore very small.
  • the rollers 12 can be rotated about their axes 12c and are provided with cylindrical running surfaces 12a.
  • One axial end face 12b of the rollers 1 2 is in contact with the surface 101 b.
  • the front cage ring 102 has a larger inner diameter d 1 (FIG. 3) than the inner diameter d2 of the outer ring 30, while the rear cage ring 101 has a smaller outer diameter d3 than the inner diameter d2 of the outer ring 30.
  • the cage 100 when mounting the roller bearing, the cage 100 can be pushed over the rollers 1 2 or vice versa, the rollers 1 2 into the cage 100, and the cage 100 can be pushed into the outer ring 30.
  • the rear end face 1 2b of each roller 1 2 abuts against the inner surface 101 b of the cage ring 101 (FIG. 3).
  • the front side wall of the outer ring 30 there is an annular recess 30 ′ with a diameter d4, through which a vertical receiving surface 30 ′ a and a horizontal receiving surface 30 ′ b are formed, and the radial inner side defines a further running surface 31 for the Rollers 12 (Fig. 2, 3a).
  • the front cage ring is in this recess 30 ' 102 so fitted that the inner surface of the vertical outer surface 30 'a facing, while the edge surface 102b of the horizontal receiving surface 30 of the cage ring 102' 102a facing b.
  • the outer surface 102c of the cage ring 102 is approximately flush with the front side surface of the outer ring 30 or is offset in relation to this.
  • the cage 100 can be mounted on the outer ring in any manner. However, the storage is preferably carried out by receiving the front cage ring 102 in the recess 30 ', in which it is supported with play and floating.
  • each strut 104 is offset inwards relative to the edge surface 101a of the rear cage ring 101, so that a larger gap 29 is formed between the running surface 31 of the outer ring 30 and the strut outer surface 104d. This gap ensures better passage of grease.
  • the cage 100 shown in FIGS. 4, 5 and 8 with the cage rings 101, 102 has the dimensions d1 and d5 or d3 in the radial direction.
  • the larger cage ring 102 has two radially aligned surfaces 102a and 102c and an axially aligned surface 102b, while the smaller cage ring 101 is provided with surfaces 101a, 101c and 101b (see FIG. 3). The following applies: d3 ⁇ d2 d 1 and d5 d4.
  • the dimensions are chosen here so that the cage does not "fall” on the rollers within the scope of its radial play, otherwise the cage could be guided radially, which is undesirable.
  • the cage is rather guided over its radial surfaces 101a and 102b on surfaces 30'b and 31.
