  • unwanted vibrations occur, which are then transmitted via the shaft, the bearing inner shell, the rolling elements and the outer bearing shell on a rolling bearing receiving housing. It is mainly transmitted structure-borne noise. Since the housing is often used together with the CVT transmission in motor vehicles such as cars or trucks, but also tractors and earth-moving machinery, there is the increased demand for noise emissions to take into account.
  • DE 10203307 A1 discloses a storage concept for rotating shafts.

  • the object is achieved in that on the outer circumferential surface of the bearing outer ring two at least partially extending over the circumference hump-like projections are present, on which rests the support portion.
  • the support is no longer necessarily present at the ends of the Borden, but is kept on the inside of the decoupling elements in the region of the largest inner diameter.
  • the hump-like projections provide a compression region between them.
  • Noise optimization in continuously variable transmissions can thus be realized efficiently.
  • the resulting vibrations on the chain links of the CVT chain, which are transmitted via the bearings on the gear housing, can be reduced thereby.
  • a decoupling of the housing in the radial direction is possible even with fixed bearings, which are still fixed in the axial direction.
  • the housing vibrations and thus the sound emissions can be significantly reduced.
  • the tolerance chain is not extended either. Also, the diameters of the shelves do not necessarily need to be ground to ensure proper function at all. As a result, a large number of grinding tolerances no longer add up.
  • the decoupling element may have a closed continuous cross-section or be broken at one point.
  • the decoupling element may have a tubular shape or the shape of a slotted sleeve. In this way, different types of installation can be realized, which increases the freedom of design.

  • the spring portion can then insert into a compression region between the projections and thereby provide the desired vibration reduction effect.
  • the anti-friction bearing can be designed to be particularly slip-resistant if the decoupling element is designed as a sleeve with a cylindrical bearing section.
  • the decoupling element can be positioned precisely on the bearing outer ring in the axial direction. It is also advantageous if the shelves take an orthogonal angle to the cylindrical support portion. The positionability of the decoupling element relative to the bearing outer ring can then be realized while simultaneously simplifying the production process.
  • the spring portion has recesses.
  • the spring behavior can be specifically adjusted so that the necessary radial rigidity is ensured. It is then possible to realize radial stiffnesses of 150,000 N / mm 2 with a setting range of 20,000 N / mm 2 around this value.
  • the recesses may be circular, triangular or slot-shaped. If the triangles are formed isosceles, this is further advantageous. It is also advantageous if the triangles are aligned with each other and offset from each other. In a circular design of the recesses, it has proven to be advantageous if three staggered rows are introduced into the section. The recesses do not necessarily end outside of the support portion, but may even partially project into it.
  • the decoupling element in a connecting region between one of the ribs and the support section has a dilution to the disposal position of a crimping step. In this way, a cup-shaped preformed decoupling element with a continuous opening from the one side can be applied to the bearing outer ring and then reshape it by a crimping process so that the second board extends inwardly away from the crimping step. A simple manufacturing process with simultaneous precise production of the rolling bearing can then be realized.
