Definitions

  • the invention relates to a rolling bearing according to the preamble forming features of claim 1, and they are particularly advantageous to radial needle bearings for supporting bearing of the secondary mass on the primary mass of a dual mass flywheel in a motor vehicle applicable.
  • dual-mass flywheels are arranged between the internal combustion engine and the transmission of a motor vehicle and are provided for increasing the driving comfort.
  • Such a dual-mass flywheel essentially consists of a disc-shaped primary mass connected directly to the crankshaft of the internal combustion engine and of a disc-shaped secondary mass arranged coaxially with this primary mass, which is connected via a coupling to the input shaft of the transmission.
  • Both masses are coupled together by a plurality of damping means arranged between them and, contrary to the effect of these damping means, can be rotated relative to one another via a friction-reducing support arranged on a bearing flange on the primary mass.
  • the primary mass is actively driven via the rotating crankshaft of the internal combustion engine, while the secondary mass driving the transmission input shaft is entrained via the damping elements, via which the irregularities resulting from imbalances of the moving masses in the drive train and the rotational irregularities resulting from the piston movements of the internal combustion engine are damped.
  • the secondary mass and the primary mass of the dual mass flywheel have in addition to sliding, cylindrical roller and ball bearings and radial needle roller bearings proved to be particularly suitable, as for example from JP 07-279 952 A or DE 1 944 576 U are known.
  • Such radial needle roller bearings consist essentially of a thin-walled outer needle sleeve with axially on both sides inwardly directed Radialborden, a plurality on the inner circumferential surface of the needle sleeve and on the outer surface of the shaft to be stored rolling bearing needles and a bearing needles in the circumferential direction uniformly spaced needle cage , wherein at least one side next to the needle cage an additional thrust washer is inserted into the needle sleeve, which is provided together with a radial board or another thrust washer inserted into the needle sleeve to limit the axial movement of the needle cage.
  • a sealing element is additionally arranged between the at least one thrust washer and the other radial flange, which is designed as a metal-reinforced or simple lip seal made of an elastomer and the sealing lip abradingly abuts the lateral surface of the shaft to be supported.
  • radial needle roller bearing differs essentially to the needle bearing described above in that it is formed on both sides next to the needle cage with angled in profile Anlaufusionn and that Roll the bearing needles instead of on the lateral surface of a shaft on the lateral surface of an additional inner ring.
  • Both thrust washers are at the same time part of two the needle bearings on both sides sealing labyrinth seals, which are further formed by the radial rims of the needle sleeve and two additional, each secured between the thrust washers and the Radialborden on the inner ring of the needle bearing metal sealing rings.
  • the thrust washers and the radial rims of the needle bearing have in each case inside the inner side a gap to the inner ring and at their inner annular surfaces a gap to the metal sealing rings, which in turn each outer diameter side have a gap to the thrust washers, so that the needle bearing on both sides by non-contact labyrinth seals with a multiple angled Sealing gap is sealed.
  • the invention is therefore based on the object to design a rolling bearing, in particular radial needle roller bearing, which at least one side with a cost-effective and easy to install and a sliding contact to be stored Shaft avoiding seal is formed.
  • this object is achieved in a roller bearing according to the preamble of claim 1 such that the at least one sealing element is designed as a labyrinth seal, which consists of two individual interlocking the and formed with complementary profile cross-sections sealing rings is metsetzbar together.
  • both sealing rings of the sealing element consist of a heat-resistant plastic and substantially each having a C-shaped profile cross section and a sealing ring is formed with a smaller outer diameter than the other sealing ring.
  • the larger diameter sealing ring is fixed to the outer circumferential surface of its outer profile leg by a press connection to the inner circumferential surface of the needle sleeve and rests with its profile web on Radialbord the needle sleeve. Due to the press connection on the inner lateral surface of the needle sleeve of the larger diameter sealing ring is thus formed as a fixed part of the labyrinth seal, while its investment ensures the Radialbord the needle sleeve that the entire labyrinth seal is arranged axially immovable in the needle hub.
  • the inventively designed roller bearing is also characterized by the fact that the smaller diameter sealing ring on the inner surface of its inner profile leg with two circumferential annular beads to fix it on the lateral surface of the shaft to be stored is formed and is arranged with its profile web parallel to the thrust washer.
  • the fixation of the smaller-diameter sealing ring on the lateral surface of the shaft to be supported thus causes it to be designed as a co-rotating part of the labyrinth seal, while the parallel and not directly adjacent arrangement of its profile web to the thrust washer is intended to wipe an additional sealing gap between this and the To form thrust washer and at the same time to create a compensation possibility of minor axial movement of the shaft to be stored.
  • the interlocking arrangement of the sealing rings of the labyrinth seal is then realized according to claim 5 such that, starting from the complementary C-shaped profile cross sections, the outer profile leg of the smaller diameter sealing ring between the profile legs of the larger diameter sealing ring and the inner profile leg of the larger diameter sealing ring between the profile legs of the smaller diameter sealing ring is arranged.
  • a multi-angled sealing gap is produced between the individual profile legs of both sealing rings, with which a high sealing effect can be achieved.
  • spacer knobs are designed as lens-shaped point elevations on the smaller-diameter sealing ring and ensure that when acting on the rolling bearing axial forces, the sealing rings do not move so far into one another that the sealing gap is closed but also always the height of the spacer studs corresponding sealing gap remains.
  • the smaller diameter sealing ring is additionally formed on the outer annular surface of its profile web with further uniformly circumferentially spaced studs to form a further sealing gap between this and the thrust washer.
  • These also formed as lens-shaped point elevations on the profile web of the smaller diameter sealing ring spacer studs are provided that when acting on the bearing axial forces of smaller diameter sealing ring does not move so far against the thrust washer that the additional sealing gap between this and the sealing ring is closed, so that here in any case, the height of the spacer studs corresponding sealing gap remains.
  • the rolling bearing according to the invention thus has the advantage over the rolling bearings known from the prior art that it is formed with a labyrinth seal which can be produced cost-effectively and which, on the one hand, avoids sliding contact with the shaft to be supported and, on the other hand, as a completely assembled structural unit integrated into the rolling bearing and can be easily handled in the bearing assembly.
  • a labyrinth seal additionally offers the possibility of being able to be used within a U-profile-shaped sheet-metal ring as a preassembled single-sight system in other suitable applications.
  • Figure 1 is an enlarged view of a cross section through an inventively designed roller bearing
  • FIG. 2 shows an enlarged view of the detail X of the rolling bearing according to the invention according to FIG. 1.
  • FIG. 1 clearly shows a radial needle roller bearing 1 suitable for supporting the secondary mass on the primary mass of a dual mass flywheel in a motor vehicle, which essentially consists of a thin-walled outer needle sleeve 2 with radial rims 3, 4 axially directed on both sides in a multiplicity the inner circumferential surface 5 of the needle sleeve 2 and on the outer circumferential surface of a shaft, not shown, rolling off bearing needles 6 and a needle bearing 6 which guides the bearing needles 6 in the circumferential direction at equal intervals.
  • the sealing element 9 is formed as a labyrinth seal, the present invention from two individual interlocking sealing rings 10, 1 1 is assembled with complementary profile cross-sections.
  • the existing of a heat-resistant plastic Sealing rings 10, 1 1 of this sealing element 9 essentially each have a C-shaped profile cross-section and a sealing ring 10 is formed with a smaller outer diameter than the other sealing ring 1 1.
  • the larger diameter sealing ring 1 1 is in such a way in the needle sleeve 2 arranged that this can be attached to the outer circumferential surface 12 of its outer profile leg 13 by a press connection to the inner circumferential surface 5 of the needle sleeve 2 and with its profile web 14 on Radialbord 4 of the needle sleeve 2 is present.
  • the smaller diameter sealing ring 10 is arranged with its profile web 20 parallel to the thrust washer 8 and has on the inner circumferential surface 16 of its inner profile leg 17, two circumferential annular beads 18, 19, with which it can be fixed on the lateral surface of the shaft, not shown.
  • the smaller-diameter sealing ring 10 also has a plurality of spacer knobs 24 on individual annular surfaces 22, 23 of its profile legs 17, 21 facing the larger diameter sealing ring 11 25, which are clearly visible as a uniform circumferentially distributed lens-shaped point elevations formed.
  • a first circumferential row of the spacer knobs 24 is arranged on the outer annular surface 22 of the outer profile leg 21 of the smaller diameter sealing ring 10 and communicates with the unspecified inner annular surface of the outer profile leg 13 of the larger diameter sealing ring 1 1 in operative connection, while a second row of the spacer knobs 25 at the annular surface 23 of the inner profile leg 17 of the diameter neren sealing ring 10 is arranged and with the also not designated inner annular end face of a radially inwardly directed extension of the profile web 14 of the larger diameter sealing ring 1 1 is in operative connection.
  • a third row of uniformly circumferentially distributed spacer knobs 28 is arranged on the outer annular surface 27 of the profile web 20 of the smaller-diameter sealing ring 10, with which a further sealing gap 29 is formed between the latter and the thrust washer 8.
