Definitions

  • the invention relates to a synthetic fiber rope, preferably made of aromatic polyamide, according to the preamble of claim 1.
  • Ropes are particularly useful in conveyor technology, such as B. at Elevators, in crane construction and opencast mining, etc., an important strong stressed machine element. It is particularly complex Stress on driven ropes, such as in Elevator construction can be used.
  • High-strength synthetic fiber ropes for example made of aromatic polyamides or aramids with high grade oriented molecular chains better meet these requirements than conventional steel cables. So point out of aramid fibers assembled ropes with the same cross section compared to conventional steel cables have a much higher load capacity and only a fifth to sixth of the specific weight. However, due to its atomic structure, the aramid fiber has one comparatively low elongation at break and low Cross strength.
  • Such a synthetic fiber rope with parallel lay stranding is e.g. known from EP 0 672 781 A1.
  • the aramid rope explained so far offers durability, high abrasion resistance and Flexural fatigue strength satisfactory values; Indeed the twisted synthetic fiber strand rope tends under tensile load tends to rotate about the longitudinal axis and / or to turn up. The unwanted untwisting of the stranded rope but can be seen over the rope cross section uneven loading of the strands different Strand layers and thus a reduction in the rope book strength cause the rope to fail.
  • the invention has for its object the disadvantages of to avoid known synthetic fiber rope and a permanent to provide reliable twisted synthetic fiber rope.
  • the advantages achieved by the invention are that the intermediate sheath with adjacent strand layer profiles adapted outer surfaces compared to a larger contact area offers the strands and thus also the spaces between the strands completely bridging the adjacent layers of strands.
  • a firm bond of inner and outer strand layers becomes one achieved higher torsional rigidity of the stranded rope. This prevents with a loaded rope according to the invention profiled intermediate sheath a twisting of the rope independently on the type of torque applied.
  • the lacing force of the top strand layer acts as a result not primarily as lateral force on the crests individual strands, but distributed over a large area, i.e. With less pressure on the entire circumferential surface of the adjacent strand layers.
  • the intermediate jacket can different longitudinal movements of neighboring strands without Relative displacement of the strands relative to the intermediate sheath record what benefits in terms of flexibility and the change of bending behavior of the rope.
  • a rope 1 is shown, as it is in elevator systems as a supporting and conveying element, for example for driving a rope pulley or rope drum is used.
  • a car frame is one in an elevator shaft guided cabin and a counterweight over a rope with each other connected. To lift and close the cabin and counterweight lower, the rope runs over a traction sheave by one Drive motor is driven. The drive torque is below The frictional connection via the wrap angle adjacent rope section stamped. Here is the rope exposed to high transverse stress.
  • the rope 1 is made up of a core strand 2 to the in a first lay direction 3 five identical strands 4 one first strand layer 5 are placed helically, and with which ten strands 4, 7 a second strand layer 8 in Parallel strike under a balanced relationship between Strand and rope twist twist are stranded.
  • the second strand layer 8 consists of an alternating one Arrangement of two types of five identical strands 4, 7 together.
  • the rope cross section shown in Figure 2 shows another five strands 7 of larger diameter, the helical in the valleys of the first bearing them Strand 5 lie, while five strands 4 with the diameter of Strands 4 of the first strand layer 5 on the tops of them load-bearing first strand layer 5 and the gaps between two neighboring strands of larger diameter Fill in 7.
  • the parallel stranding produces a longitudinal load on the rope 1 of the rope core 9 opposite to the direction of lay 3 directed torque.
  • the rope core 9 With the rope core 9 are seventeen strands 10 in a direction opposite to the first beat direction 3 second lay direction 11 to a cover strand layer 12 in Cord stranded.
  • the lay length ratio of the outside lying strands 10 with strands 4, 7 of the inner strand layers 5, 8 is 1.6 in the illustrated embodiment.
  • the Stranding the cover strand layer 12 builds a torque under load on in the direction opposite to the second impact direction 11 turns.
  • the intermediate jacket 13 consists of an elastically deformable material, such as. B. Polyurethane or polyester elastomers, and is based on the stranded rope core 9 or sprayed extruded.
  • the freshly applied intermediate coat 13 plastically deformed, being closely related to the Circumferential sheath contours of the strand layers 8 and 12 creates and fills all gaps and the embossed grooves 18, 19 of the strand layers 8, 12 resting against him.
  • the profiled intermediate jacket 13 envelops the second strand layer 8 thus tubular and prevents the strands from coming into contact 4, 7 with the strands 10. In this way, he avoids one Wear of strands 4, 7, 10 by mutual Rubbing each other while the rope 1 runs over the traction sheave, as a result of relative displacements of the strands 4, 7, 10 among themselves, these to balance out Tension differences, e.g. when deflecting the rope under Load on the traction sheave.
  • the intermediate jacket 13 creates a friction and positive transmission of the load on the rope 1 in the top strand layer 12 torque built up to the second Strand layer 8 and thus on the rope core 9, the Parallel stranding opposite to direction of lay 3 directional torque builds up.
  • the frictional resistance between the strands is 4,7,10 and the intermediate jacket 13 with u> 0.15 selected such that almost no relative movement between strands and the Intermediate jacket 13 takes place, but the intermediate jacket 13 follows the compensatory movements through elastic deformation.
  • the Elasticity of the intermediate jacket 13 is greater than that the wire impregnation and the load-bearing wire material and thus avoids their premature damage.
  • the total stretch of the chosen material of the intermediate sheath 13 in any case larger than the maximum occurring Relative movement of the strands 4,7,10 with each other.
  • the radial can over the thickness 20 of the intermediate shell 13 Distance of the top strand layer 12 to the axis of rotation of the rope 1 to be controlled in order to Torque ratio of the acting in the loaded rope 1, oppositely directed torques of the top strand layer 12 and neutralize the parallel stranded rope core 9.
  • the Thickness 20 of the intermediate jacket 13 increases with the diameter the strands 10 and the strands 4 and 7 increase choose.
  • the thickness 20 of the intermediate casing 13 to be dimensioned in such a way that when loaded, completely filled strand spaces 21, 22 a Residual sheath thickness of 0.1 mm between strands 4.7 and 10 of the adjacent strand layers 8 and 12 is ensured.
  • the plastically deformed intermediate jacket 13 causes even torque transmission over the entire Circumferential surface.
  • the volume of the inter-strand spaces can due to the alternating arrangement of diameter 7 and smaller diameter strands 4 of the second strand layer 8 be minimized.
  • the rope can also be used use a wide variety of conveyor systems, e.g. For Elevators, mine hoists in mining, load cranes such as construction, Hall or ship cranes, cable cars and ski lifts as well as Traction devices for escalators.
  • the drive can both by Friction over traction sheaves or Koeppe sheaves as well by rotating rope drums on which the rope is wound will be done.
  • Under conveyor rope is a running, to understand driven rope, sometimes as a pull or Carrier rope is called.
