Definitions

  • belt-type suspension elements which have tension members and a jacket arranged around the tension members are also used.
  • Such belt-like support means are, similar to conventional steel cables, guided over traction sheaves and pulleys in the elevator system.
  • belt-type suspension elements are not guided in the rollers or traction sheaves, but the belt-like suspension elements lie essentially on the deflection rollers or traction sheaves.
  • WO 2013/172824 discloses coated rollers for elevator installations. By choosing the coating, it is thus possible to influence the coefficient of friction between roller and suspension element.
  • a disadvantage of this solution is that only a limited number of materials is available for the description of steel rollers, so that an influence of the friction coefficient can only be carried out in the context of the few available coating materials.
  • these wear in the prior art known coatings of rolls does not meet the different requirements of rolls in elevator systems.
  • WO 2013/010878 also discloses known rollers with tread portions having different coefficients of friction.
  • an object of the present invention to provide an elevator installation in which the disadvantages occurring in the prior art do not exist.
  • an elevator system is to be made available in which the different requirements with respect to traction between belt-like suspension elements and rollers are better coordinated.
  • an elevator installation in which initially a belt-type suspension element is guided via at least one roller.
  • a contact surface of the roller for interacting with the belt-like support means in this case has an anisotropic structure.
  • a coefficient of friction between the suspension element and the contact surface in a circumferential direction of the roller is greater than a coefficient of friction between the suspension element and the contact surface in an axial direction of the roller.
  • Such a trained role for an elevator system has the advantage that thereby the different requirements with respect to a traction behavior between the belt-like suspension element and role optimally taken into account.
  • a higher coefficient of friction in the circumferential direction of the roller is achieved that a traction for transmitting the driving forces from the roller on the belt-like support means and the belt-like support means can be optimally designed on the role.
  • it is achieved by a lower coefficient of friction in the axial direction of the roller that the belt-like support means can better lead to the role.
  • excessive friction between the suspension element and the roller in the axial direction makes lateral guidance of the suspension element on the roller more difficult.
  • the lateral guidance of the belt-like support means is improved on the roller, for example laterally derailing suspension means can be prevented.
  • a tolerance range with respect to a diagonal pull of the suspension element on the roller can be increased.
  • a surface roughness in a circumferential direction of the roller is larger than a surface roughness in an axial direction of the roller.
  • a larger surface roughness leads to a greater coefficient of friction between the support means and contact surface of the roller, and a smaller surface roughness leads to a smaller coefficient of friction between the support means and contact surface of the roller.
  • the surface roughness in the circumferential direction of the roller is designed such that with a jacket of the belt-like support means made of polyurethane a coefficient of friction ⁇ between 0.2 and 0.6, preferably between 0.3 and 0.5, particularly preferably between 0, 35 and 0.45 results.
  • the surface roughness in the axial direction of the roller is designed such that with a jacket of the belt-like support means made of polyurethane a friction coefficient ⁇ between 0.05 and 0.45, preferably between 0.1 and 0.3, particularly preferably between 0, 15 and 0.25 results.
  • the anisotropic structure of the contact surface of the roll is formed by a chemical or electrochemical process in an etching solution.
  • Such an electrochemical or chemical process in an etching solution has the advantage that it is inexpensive and that a variety of anisotropic structures can be formed thereby.
  • the respective needs of the different applications of roles in elevator systems can be optimally taken into account.
  • the anisotropic structure of the contact surface of the roll is formed by laser beam machining, electron beam machining or ion beam machining.
  • the contact surface of the roller is executed cambered.
  • Such a contoured design of the roller has the advantage that its contact pressure of the suspension element on the roller can be achieved.
  • the contact surface of the roller in the circumferential direction has a plurality of substantially V-shaped ribs and a plurality of substantially V-shaped grooves.
  • the roller is a traction sheave.
  • the roller is a counterweight pulley or cab deflection pulley.
  • the contact surface of the roller is formed of steel.
  • the contact surface of the roll of hardenable steel is formed, wherein at least portions of the contact surface are hardened.
  • the provision of flanged wheels on the rollers has the advantage that in addition lateral derailing of the belt-like suspension means on the roller is made more difficult.
  • rollers can basically be used at different locations in an elevator installation and in different types of elevator installations. Such rollers can be used in elevator systems with counterweight and also in elevator systems without counterweight. Furthermore, such rollers can be used in elevator systems with different suspensions, such as 1: 1 suspensions, 2: 1 suspensions or 4: 1 suspensions. Rollers may be arranged as deflection rollers on a counterweight or a cabin or in a shaft, or the roller may be formed as a traction sheave of a drive.
  • FIG. 1 an exemplary embodiment of an elevator installation 1 is shown.
  • the elevator installation 1 comprises a car 2, a counterweight 3, a drive 4 and a belt-like suspension element 5.
  • the belt-like suspension element 5 is fixed by a first suspension element fastening 7 in the elevator installation 1, guided by a counterweight deflection roller 10, via a traction sheave 4 of the drive guided, guided over two cabin deflection rollers 8 and secured by a second support means attachment 7 turn in the elevator system 1.
  • the elevator installation 1 is arranged in a shaft 6.
  • the elevator system is not arranged in a shaft, but for example on an outer wall of a building.
  • FIG. 2A an exemplary embodiment of a roller 4, 8, 10 is shown schematically.
  • the figure shows parts of a cross section of the roller 4, 8, 10.
  • the roller 4, 8, 10 has an inner ring 11 and an outer ring 12. Between the inner ring 11 and the outer ring 12 rolling elements 13 are arranged.
  • the outer ring 12 forms the contact surface 15 of the roller 4, 8, 10th
  • the outer ring 12 flanges 17.
  • the flanged wheels 17 are each arranged laterally to the contact surface 15, so that lateral slipping of the belt-like support means (not shown) can be prevented.
  • a section of an exemplary embodiment of a support means 5 is shown.
  • the support means 5 comprises a plurality of parallel in a common plane juxtaposed tensile carrier 32, which are surrounded by a common jacket 31.
  • the suspension element 5 is equipped with longitudinal ribs on a traction side. Such longitudinal ribs improve traction of the support means 5 on the traction sheave 4 and also facilitate lateral guidance of the support means 5 on the traction sheave 4.
  • the support means 5 can also be designed differently, for example without longitudinal ribs, or with a different number or a different arrangement of Tensile carrier 32.
  • FIG. 2D another exemplary embodiment of a roller 4, 8, 10 is shown.
  • a circumferential direction 21 and an axial direction 22 are marked on the illustrated roller 4, 8, 10 on the contact surface 15.
  • the anisotropic structure of the contact surface 15 is not apparent in this exemplary representation, since such small structures are not visible in the selected scale of the roller 4, 8, 10.
