Definitions

  • the invention relates to a traction means, in particular for an elevator system, wherein the traction means is driven by a traction sheave and an elevator system with a traction means.
  • each individual rope is uniquely assigned its own rope groove on the traction sheave. Each rope dives at least in part of its diameter in the associated cable groove. Each individual rope is an independent tension element and can also be operated individually. For higher outputs, either several ropes can be used in parallel, or the rope diameter is increased accordingly.
  • the single rope is thus not only traction means for transmitting the tensile forces, but is also directly involved in the transmission of traction forces.
  • Ropes have the advantage over belt technology that the force can be transmitted directly from the traction sheave to the ropes.
  • the transmission of traction forces from the traction sheave to the traction means takes place here via the friction between traction disk and elastomer material, the traction forces then being transmitted to the traction elements via shear stresses in the elastomer material and the adhesive mechanism between elastomer material and traction elements.
  • the material properties, especially the shear strength of the elastomeric material therefore play a decisive role in this case.
  • the introduction of force into the individual tension elements thus takes place indirectly.
  • the tension elements themselves are thus responsible only for the transmission of tensile forces.
  • EP 1 396 458 A2 describes an elevator device in which a flat belt of elastomeric material reinforced with reinforcements is used as the traction means.
  • EP 1 555 234 B1 shows an elevator installation with a V-ribbed belt.
  • Belts offer over the ropes the advantage that on the one hand the handling is easier, because not individual ropes must be placed on corresponding grooves of the traction sheave, and that also small traction sheave diameter can be used without problems, since the embedded tension members usually have relatively small diameter.
  • belts as traction means are virtually maintenance-free, since no lubrication is required.
  • the transferable force is, as already described above, in addition to the friction between the traction sheave and elastomer also on the shear strength of the elastomer and the quality of the embedding of the tension members in the elastomer, ie, the adhesion between the elastomer and tension member dependent. The importance of the material properties of the elastomer increases with increasing distance of the tensile carriers from the force application zone.
  • No. 6,739,433 discloses a traction device for an elevator installation, which is designed as a profiled flat belt, so that the surface available for friction between traction disk and belt is slightly larger.
  • the transferable force is thus slightly higher than in a non-profiled flat belt, but here is the zone of power transmission between the traction sheave and traction means still clearly spaced from the tension members, so that the elastomeric material of the flat belt is relatively heavily subjected to shear.
  • a traction means which circumvents the mentioned disadvantages by a composite rope, are connected to a composite rope in parallel, lying with elastomeric material individual tensile carriers by a one-sided elastomeric connector layer and the tensile carriers in corresponding Engage grooves of the traction discs.
  • the tensile carriers engage at least 25% of their total diameter in the grooves of the traction sheave.
  • the invention has for its object to provide a traction means of the type described above that compared to the cited prior art, a further reduced width of the traction disc allows and play in which the properties of elastomeric materials only a minor role.
  • the traction means is formed as a composite rope, are sheathed in parallel single ropes having a first diameter, each with an elastomer layer of a predetermined thickness to tensile carriers each having an overall diameter and the tensile carriers by a one-sided elastomeric connector layer substantially are interconnected over their entire length and the tensile carriers engage in corresponding grooves of the traction discs, wherein the elastomeric connector layer is disposed on the side of the tension members facing away from the groove engaging in the grooves of the traction disc and that adjacent tensile carriers at least partially in groups at least two tensile carriers are summarized such that the Buchträ- groups each engage in a common corresponding groove of the traction discs.
  • This arrangement has the advantage that the composite cable allows a further reduction of the width of the traction disc by the partial omission of the distances between the individual tension members. Compared to the rope technique, there is the advantage that the composite cables are very easy to handle each other by the elastomeric connection.
  • the belt technology is advantageous in the case of the composite cables according to the invention in that the force introduction zone is at least partially identical to the contact zone of the tension members with the traction sheave, because the tension members themselves engage in the grooves of the traction sheave and are not embedded in a relatively thick elastomer matrix, through which the tension members are spaced from the force application zone.
  • the elastomeric connector layer does not have to accommodate significant shear stresses for power transmission. Its main purpose is to simplify handling.

  • the ratio of the diameter of the individual cables to the thickness of the sheathing u d / u is greater than or equal to 3.
  • the thickness of the casing is so thin in relation to the diameter of the individual ropes that the properties of the casing play a particularly small role.
  • the sheath is formed of an elastomer which differs from the elastomer of the connector layer.
