Definitions

  • the invention relates to a traction system, in particular for an elevator installation, wherein the traction system comprises at least the following components, namely at least one traction means and at least one traction sheave and an elevator installation.
  • Traction systems for elevator systems are known per se.
  • a pulling means ropes but also belts are used, being used as belt both flat belt and V-ribbed belt or toothed belt.
  • 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 corresponding rope 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. In the belt technology is still the connecting elastomeric material between the actual tension members and the traction disc.
  • the tension elements are thus exclusively responsible for transmitting the tensile forces.
  • wider belts or belts of higher performance class with larger belt pitch and stronger tension elements can be used.
  • the belts are generally wider than they are high to ensure a stable belt run on the pulley.
  • the EP 1 396 458 A2 describes an elevator device in which a belt reinforced with reinforcements flat belt made of elastomeric material is used as traction means.
  • the EP 1 555 234 B1 shows an elevator system 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 are virtually maintenance-free as traction means, since no lubrication is erfoderlich.
  • the transferable force is in addition to the friction between the traction sheave and elastomer and the quality of the embedding of the tension members in the elastomer, d. h., Depending on the adhesion between elastomer and tensile and the shear strength of the elastomer dependent.
  • the invention has for its object to provide a traction system of the type described, which is easy to handle, with high tensile forces are transferable and the traction means over the known belt technology allows a less broad-based drive unit.
  • the traction device of the traction system is designed as a composite rope, are sheathed in parallel single ropes with a first diameter, each with an elastomer layer of a predetermined thickness to tensile carriers, each with an overall diameter and the tension members by a one-sided elastomeric connector layer substantially are interconnected over their entire length, wherein the elastomeric connector layer is disposed on the side of the tension members which faces away from the groove engaging in the grooves of the traction sheave side, and the tensile carriers engage in corresponding grooves of the traction disc such that the immersion depth of the individual cables of the tension members in the grooves of the traction sheave is at least 25% of the diameter of the single ropes.
  • the composite rope is so easy to handle and is almost maintenance-free like a belt. Because of the directly into the grooves of the traction disc engaging traction carrier contacts at least the traction disc closest to the vertex of each tension member the traction sheave. The zone of power transmission between traction sheave and traction means is located directly in the engagement zone, whereby a high power transmission is given. Due to their small thickness, the shear strength of the sheath is of very little importance.
  • Thin ropes can be used so that small traction disc diameters and narrow traction discs are possible. For each compound rope only one connecting element for connection to the example to be lifted elements is necessary.
  • the thickness of the sheathing of the individual cables in the range of 0.2 - 2 mm.
  • the thickness of the sheathing of the individual ropes in the range of 0.5 - 1 mm.
  • the diameter of the individual ropes is between 1.5mm and 8mm.
  • the diameter of the individual cables is between 1.8 and 5.5 mm.
  • the ratio of the diameter d of the individual cables to the thickness u of the sheathing 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.
  • the elastomer or the elastomers is preferably a polyurethane or polyurethanes.
  • Polyurethane has both good friction and good adhesion properties and is relatively insensitive to shear.
  • the sheathing of the individual cables has an outer contour facing the traction sheave whose cross-section is deviating from a partial circle shape.
  • the cross section of the outer contour is trapezoidal.
  • the cross section of the outer contour is square.
  • the cross section of the outer contour is conical.
  • the configuration of the cross sections of the casing in different geometries has the advantage that the composite rope is therefore adaptable to a large number of traction disk profiles.
  • the connector layer on its side facing away from the traction disc on a profiled surface.
  • This profiling is used to better guide the composite ropes when they must be performed over their back to pulleys.
  • each composite rope has at least four individual ropes.
  • the individual cables are arranged alternately between S and Z impact.
  • the number of individual ropes per compound rope is even.
  • the individual cables are made of steel.
  • the object is further achieved in that the elevator installation has a traction system according to at least one of claims 1 to 17.
  • Such an elevator system has the advantage that on the one hand the assembly is facilitated due to the good handling of the composite cables according to the invention, on the other hand, no wide-build traction drum is required.
  • Composite cable 1 shown in cross-section has four individual cables 2 with a diameter d, which are each coated with a sheath 3 having a thickness u of an elastomer to tension members 4.
  • the tension members 4 are fixedly connected to one another with a connector layer 5, the connection being produced by vulcanization of the elastomeric jacket 3 to the connector layer 4 and the individual cables 2.
  • the composite rope 1 rests on a traction sheave 6, wherein the tension members 4 engage in grooves 7 of the traction sheave 6.
  • the connector layer 5 is arranged on the side of the tension members 4, which faces away from the traction sheave 6.
  • the tension members 4 engage in the grooves 7 of the traction sheave 6 in such a way that the individual cables 2 of the tension members 4 dip into the grooves 7 about 50% of their diameter.
  • the sheath 3 of the individual cables 2 have a different geometry from the circular shape. These Geometries improve the engagement of the composite ropes 1 in traction discs, not shown here, which have a different profile from the round shape.
  • correspondingly shaped composite cables 1 can also be used on traction discs of V-ribbed belts.
  • a compound rope 8 which faces away from a traction sheave, not shown here back side a rib profile 9 of spaced-apart longitudinal ribs 10. If required, the longitudinal ribs can engage corresponding deflection rollers (not shown here) and thus improve the guidance of the composite rope 8.
