Definitions

  • This invention relates to a driving belt having a trapezoidal cross-sectional configuration and suitable to transmit a torque between expanding pulleys formed of pairs of conical discs defining a V-shaped space between them for receiving the driving belt,
  • driving belt comprises a carrier in the form of one or more endless, metal belts having a continuous series of transverse members freely slidable with respect to the carrier thereon, which transverse members define the cross-sectional configuration of the driving belt.
  • Such a driving belt is known from Dutch patent 142,767, in which the operation of the driving belt, which transmits the torque by means of pushing force, is explained.
  • Such a driving belt is particularly suitable for use in an infinitely variable transmission.
  • a drawback of such a driving belt is that under certain working conditions the transverse members may shift in transverse direction to cause heavy wear. During this lateral shifting the transverse members strike the flanks of the belt or belts forming the carrier.
  • At least a number of the substantially parallel surfaces with which the transverse members are in contact with each other in a straight part of the belt are provided with friction-increasing means.
  • the friction-increasing means comprise a knurling of small depth, for instance some hundredths of a millimeter.
  • this knurling can be formed by grinding the surface in two directions, called cross-grinding.
  • the knurling on the surface is such that it is maintained during use of the driving belt, and consequently does not easily wear out, or disappear during running in of the driving belt.
  • Fig. 1 shows schematically two V-shaped pulleys 1, 2.
  • the running diameter of the driving belt 3 on a pulley 1, 2 can be varied by adjusting the mutual distance of the conical pulley parts of the V-shaped pulley 1, 2.
  • the ratio of the rotary speeds between the schematically shown shafts 4 and 5 can be varied infinitely in this way.
  • the driving belt 3 comprises a number of metal transverse members 6 slidably mounted on an endless carrier 7.
  • This carrier 7 may comprise, for example, a number of metal belts combined into one or more belt packs.
  • Each of the preferably two belt packs comprises a number, for example ten, of superposed metal belts which are slidable about and with respect to each other. (In Fig. 1 a pack of only 4 belts is shown).
  • the transverse members 6 are slightly tapered radially inwardly of the driving belt, which enables the driving belt 6 to run about the pulley with curvature, as shown in Fig. 1.
  • Fig. 2 shows a transverse member 6 (shown in Fig. 1 in side elevational view) in front elevational view.
  • Transverse member 6 comprises two side surfaces 8 adapted to cooperate with the conical pulley parts of the V-shaped pulley 1, 2 and two recesses 9, each adapted to receive a belt pack 7, as shown.
  • the broken line 10 in Fig. 2 indicates the tilting line or the tilting zone, i.e. the place where the transverse member 6 starts tapering.
  • the transverse members are in contact with each other with the surface shown in cross-hatched lines in Fig. 2 above the broken line 10.
  • This hatching indicates the two grinding directions in which the surface has been ground so as to produce such grooves in the surface-that with relatively small pressure forces between the transverse members the mutual friction in transverse direction is great.
