Definitions

  • the invention relates to an elevator in which flat belts are used as support means for carrying and driving an elevator car. It refers to the problem of flat belts on pulleys, d. H. to lead to drive and deflection of a lift system.
  • Out EP 1396458 A is a flat belt with longitudinal ribs on the traction side and / or on the back known.
  • Out AU 246 87 71 A is a load element consisting of several Ceifrigern which are covered with elastomeric material known.
  • US 6,401,871 is a support means for a lift known, which has the shape of a flat belt with a rectangular cross-section and the belt body consists of an elastic material and contains a plurality of parallel to its longitudinal direction embedded tensile cords.
  • two different means are proposed. According to a first proposal, the belt running surfaces of the flat belt as well as the pulley surfaces of the pulleys are provided with complementary contours. These contours ensure guidance of the flat belt on the pulleys.
  • the flat belts are guided by disc-shaped guide elements which project beyond the pulley running surfaces at the edge of a pulley or between a plurality of pulley surfaces of a pulley.
  • a belt guide with contoured running surfaces also increases traction between a traction sheave and the flat belt.
  • This solution has the disadvantage that due to the increased traction capability there is a safety risk that in a situation in which the elevator car or the counterweight rests on their lower travel limits, the traction between the traction sheave and the flat belt remains so high that the elevator car or the Counterweight can be moved further up.
  • the present invention has for its object to provide a lift with flat belt as a support means, which does not have the disadvantages mentioned, d. H. to provide an elevator in which the flat belts can be safely and wear-resistant on the drive and deflection of the elevator system without elaborate and expensive management measures, such as crowned or double-conical disc running surfaces are required.
  • this object is achieved in that in an elevator, the at least one pulley and at least one flat belt for carrying and moving an elevator car and the flat belt wraps around a portion of the circumference of the pulley, the flat belt has at least one guide groove in the region of a first belt running surface, and the pulley is provided with at least one guide rib projecting from its disk running surface extending in the circumferential direction of the disk running surface; Guide rib and the guide groove in the direction of the axis of the pulley clearance is present.
  • the advantages achieved by the invention are essentially to be seen in the fact that the laterally directed guide forces which occur between the guide groove of the flat belt and the guide rib of the belt pulley do not act on it in the edge region of the flat belt, as in the aforementioned belt guide with disk-shaped drives acting on the belt edge guide elements.
  • the above-described problem of the belt edge rising at the disc-shaped guide elements is eliminated in the solution according to the invention.
  • an increase in the maximum traction force due to traction-increasing guide contours on the traction sheave and the flat belt is avoided.
  • a secure guidance of the flat belt is achieved with simple and cost-saving means.
  • An undesirable increase in traction force transferable between a traction sheave and the flat belt is avoided by providing, when the first belt surface of the flat belt rests on the disk running surface and the guide rib engages the guide groove, between the guide rib and the guide groove in the direction of the axis of the pulley play ( Axial play S a ) is present.
  • the guide rib of the pulley is 0.1 mm to 2 mm narrower than the guide groove of the flat belt, so that the axial play S a between the guide rib and the guide groove is 0.1 mm to 3 mm. This ensures that on the one hand the guide causes no increase in traction and on the other hand, the possible transverse displacement of the flat belt on the pulley remains relatively low.
  • the axial clearance S a between the guide rib and the guide groove in dependence on the width of the flat belt, wherein the axial clearance S a should preferably be 0.5% to 10% of the width of the flat belt.
  • the depth of the guide groove and the height of the guide rib so to match one another between the two in the radial direction play (radial play S r ), when the first belt running surface of the flat belt rests on the disc running surface of the pulley.
  • the guide groove as well as the complementary shaped guide rib on a trapezoidal or a triangular or a circular section-shaped cross-section are simple and accurate to produce and are ideal for transferring occurring between flat belt and pulley shear forces.
  • a belt guide comprising a guide groove and a guide rib with trapezoidal or triangular cross-section, when the angle ⁇ between the flanks of the guide groove or the guide rib in the range between 0 ° and 120 °, preferably between 10 ° and 60 ° is.
  • a belt guide which is particularly resilient and wear-resistant in the transverse direction of the belt is achieved in that the surface of at least one guide groove of the flat belt is provided with a fabric reinforcement and / or with a friction-reducing and / or wear-resistant coating.
  • An advantageous embodiment of the invention is that the elastic material of the belt body of the flat belt, a friction coefficient reducing additive is attached.
  • This is the usually high coefficient of friction between reduces the elastic material of the belt body and the disc running surface of the pulley, so that the burden of the guide groove of the flat belt by the lateral forces required for its leadership are lower, which makes the guide functionally reliable and low-wear.
  • additives of polyethylene or cotton fibers are suitable for reducing said coefficient of friction.
  • An embodiment of the invention which is expedient for ensuring the operational safety of the elevator consists in that the elevator comprises a plurality of parallel arranged, provided with guide grooves flat belt as a support means and the pulley has a plurality of juxtaposed disc running surfaces, each of the disc running surfaces is provided with at least one guide rib.
  • a minimal reduction in the load capacity of a flat belt designed according to the invention with a guide groove is achieved in that the arrangement of the tension cords in the belt body is selected such that they are spaced farther apart in the region of a guide groove than outside such a region. It is therefore dispensed with a uniform distribution of the tension members to to be able to embed as many of them as possible in the belt body.
  • a particularly versatile embodiment of the invention is that the flat belt has a spine guide rib protruding from a (rear) second belt running surface.
  • This spine guide rib may cooperate with a guide groove in the disc running surface of a deflecting pulley which rotates the flat belt so as to contact the deflecting pulley with its second belt running surface.
  • This embodiment makes it possible to realize support means arrangements with guided flat belts, in which the flat belts are guided over a plurality of pulleys so that they are thereby curved in opposite directions.
