Definitions

  • the invention relates to a traction mechanism drive, in particular for an elevator installation.
  • Traction drives for elevator systems are known in the art.
  • Ropes or belts are often used, which are drivable by means of a traction sheave.
  • the belts used are flat belts, V-ribbed belts or toothed belts.
  • each individual rope is uniquely assigned its own rope groove on the traction sheave driving the traction means.
  • 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 capacities either several ropes can be used in parallel or the rope diameter can be increased.
  • the single rope is not only traction means for transmitting the tensile forces, but is also directly involved in the transmission of traction forces.
  • Ropes as traction means have the advantage that the force is transmitted directly from the traction sheave on the ropes.
  • EP 1 396 458 A2 discloses 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 discloses an elevator installation with a V-ribbed belt.
  • Belts offer over individual ropes the advantage that on the one hand the handling is easier, since when building or maintenance of the belt drive not every single rope must be placed on each corresponding groove of the traction sheave, but only the elastomeric body in which the tension members are embedded on the Traction disc must be placed.
  • small traction sheave diameter can be used because the embedded tension members usually have relatively small diameters.
  • belts as traction means are virtually maintenance-free, since no lubrication is required.
  • the transferable force is u.a. also dependent on the shear strength of the elastomeric material. Due to the shear of the elastomeric material such a belt is fatigued.
  • the US 6,739,433 discloses a traction means for an elevator system, which is designed as a profiled flat belt, so that the friction between traction and Belt available area is increased.
  • the transferable force is thus 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 by a thick compared to the diameter of a tension carrier elastomer layer of the elastomer body, so that the elastomeric material of Flat belt is also heavily loaded on shear.
  • a traction mechanism which consists of several juxtaposed and spaced apart tension members in the form of steel cables, which are sheathed by elastomer and are interconnected by a common backsheet, wherein the tension members at least 25% engage in the corresponding grooves of the traction disc.
  • the invention has for its object to provide an alternative traction drive of the type described, with which high tensile forces can be transmitted without the risk of premature material fatigue, it should be compared to the known belt technology less wide drive units are required.
  • the traction mechanism in that it consists of a traction means and at least one traction sheave through which the traction means is driven, wherein the traction means comprises tension members, which are sheathed by elastomeric material to sheathed tension members, wherein the sheathed tension members in Cross-section of the traction means in a plane next to each other are spaced apart from each other, so that between two sheathed tension members a space is provided, wherein the sheathed tension members are connected by a back layer with each other, the free space on the side facing away from the back layer to at least over the Center of the strength member is sufficient and wherein the ratio of the second diameter of the sheathed strength member to the first diameter of the reinforcement is between 1.05 and 1.7, wherein each sheathed tensile carrier in each case a corresponding groove de engages the traction sheave, wherein the elastomeric backing layer is disposed on the side of the tensile member facing away from the side
  • the traction mechanism according to the invention is easy to handle and is almost maintenance-free.
  • the traction means consists of several tension members, which are comparable to several individual ropes of the rope technology.
  • the tensile carriers are sheathed with a very thin elastomer layer to the diameter of the tension member and connected to each other with a backing layer.
  • the tension members are spaced apart on their lying on the traction disc wide side only by a very thin elastomer layer of the traction surface. This has the advantage that the thin sheathing material of the reinforcement is only slightly subjected to shear and material fatigue hardly takes place, the forces can still be transferred very well.
  • the ratio of the second diameter of the coated strength member to the first diameter of the strength member for example, in the plane which is spanned by the centers of the strength member.
  • Each tension member of the traction means engages in each case a corresponding groove of the traction disk, wherein the elastomeric backing layer is arranged on the side of the tension members facing away from the groove engaging in the grooves of the traction sheave and wherein at least one bare tensile member at least 5% and maximum to 25% of its diameter engages in the corresponding groove of the traction disc. Due to the directly engaging in the grooves of the traction sheave tension member is given a high power transmission. The zone of power transmission between traction sheave and traction means lies directly in the engagement zone. Due to the small thickness of the sheath, the shear strength of the sheath is of very little importance.
  • the traction sheave has a cross-sectional shape of the groove, which corresponds to a partial circle shape with a radius R2.
  • R2 can be between 0.8 mm and 8.0 mm, preferably between 1.1 mm and 6.0 mm.
  • the sheath of the tension members has an outer contour facing the traction disk, the cross section of which corresponds to a pitch circle shape having the radius R 1.
  • R1 can be between 0.75 mm and 4.0 mm, preferably between 1.0 mm and 2.5 mm.
  • R1 is 1.75 mm and R2 is 1.8 mm to 2.2 mm.
  • radius R2 is greater radius Rl. If the traction means is bent over the traction sheave, the radius R 1 of the traction mechanism becomes larger as a result of compression of the traction means elastomer, and the groove cross-sectional contour R 2 of the traction sheave adapts, and reliable guiding and straight running are made possible. It is advantageous if the traction sheave laterally has elevations in the form of flanged wheels. As a result, the lateral displacement of the tension members of the traction means is prevented, so that the traction means can be driven and guided safely by the traction sheave. It is particularly advantageous if the flanged wheel is arranged at a distance which is at most 1 A of the groove cross-sectional diameter away from the lateral edge of the traction means.
  • the elevator installation according to the invention is characterized in that it has a traction mechanism drive as described above.
  • a cross section is shown by a traction mechanism, which is particularly suitable for use in an elevator system.
  • the traction mechanism drive has a traction means 1 and a traction sheave 9, through which the traction means 1 can be driven.
  • the traction means 1 has six tension members 2, which are encased by elastomeric material 11 to sheathed tension members 3.
  • the tension members 2 are ropes made of steel.
  • the sheathed tensile carriers 3 are - viewed in cross-section of the traction means - arranged in a plane next to each other in such spaced relation to each other, so that between two immediately adjacent sheathed tension members 3, a free space 6 is formed.
  • the sheathed tensile carrier 3 are connected by a back layer 4 back to each other.
  • the free space 6 begins on the side facing away from the backsheet 4 and extends beyond a plane 12, which is spanned by the centers 5 of the tension members 2 out.
  • the diameter (d2) of the sheathed tension member 3 is 3.5 mm and the diameter (dl) of the uncoated, bare tension member 2 is 2.5 mm.
  • the ratio of the second diameter (d2) of the sheathed tension member 3 to first diameter (dl) of the tension member 2 is 1.4.
  • the sheathing of the tension member 2 with elastomeric material is comparatively thin at 0.5 mm. This has the advantage that the cladding material is only slightly subjected to shear and the elastomer material is not significantly fatigued. In addition, the forces of the traction disc can be transferred very well.
  • the sheathing 3 of the tension members 2 has an outer contour facing the traction sheave 9, the cross section of which corresponds to a pitch circle shape and has a radius R1 of 1.75 mm.
  • the traction sheave 9 facing broad side of the traction means consisting of part circle forms, wherein the forming the part circular sheathed steel cables engage in corresponding grooves 10 in the traction sheave 9.
  • the grooves 10 have a contour which corresponds to a circular circle shape with the radius R2 of 1.85 mm.
  • the tension members 2 have at least one engagement depth B of 5% to a maximum of 25% in the grooves 10 of the traction sheave 9 without and despite their elastomer sheathing, here the engagement depth B is 20%.
  • the sheathing of the reinforcement and the back layer 4 are made of PU.
