Definitions

  • the belt ribs and belt grooves may also be transverse to the longitudinal axis of the support and / or drive element and, accordingly, the roller ribs and roller grooves run at least approximately in the direction of the axes of rotation of the rollers. This essentially improves the blowing properties between the rollers and the belt.
  • Such reinforcing inserts can be arranged, for example, in a greater training or in a denser arrangement in the region of the longitudinal axis, whereby the belt in the belt edge region easier is deformable than in the belt center area.
  • Figure 1 shows an arrangement according to the invention with two rollers and a directly between them belt.
  • 4A is a side view of a portion of another belt with a textured belt main surface in an extended position
  • Fig. 5B shows a further arrangement according to the invention, with two rollers whose axes of rotation intersect at an angle of approximately 90 °, and with a belt extending directly between them, in a second embodiment;
  • Fig. 6 shows an elevator system according to the invention, in a simplified representation.
  • the rollers 10 and 20 rotate in opposite directions. If, for example, the belt 30 moves in the direction of the arrow 31, then the roller 10 rotate in the direction of the arrow 11 about a first axis of rotation 12 and the roller 20 in the direction of the arrow 21 about a second axis of rotation 22.
  • the belt 30 has a longitudinal geometric center axis 32 and a cross-section bounded by two belt main surfaces 33, 34 and by two belt side surfaces 35, 36 (edges).
  • the belt main surface 33 has a structure that is complementary to the structure of the peripheral surface 13 of the roller 10 and also complementary to the structure of the peripheral surface 23 of the roller 20.
  • the term 'complementary' should not be said that the structuring of the rollers 10, 20 on the one hand and the belt 30 on the other hand are geometrically exactly complementary with just running belt 30.
  • rollers 10, 20 and the belt 30 are designed so that the rollers 10, 20 and the belt 30 in the existing geometric relationships at the contact areas between the belt 30 and the roller 10 and 20 are complementary in a way that a satisfactory interaction comes about.
  • reinforcing inserts whose stress / strain ratio (Young's modulus) is smaller can be provided in the edge portions.
  • this can be achieved, for example, by different production methods of the strands (eg by different degrees of twisting).
  • the length L of the region A, in which the rotation of the belt 30 takes place depends on the distance L1 of the rollers 10, 20 (see FIG. 1), but that a certain minimum length L, or a minimum distance L1 between the rollers 10, 20, should not fall below.
  • FIG. 4A shows the belt 30 in an elongated or straight arrangement
  • Fig. 4B in a bent arrangement, when it wraps around a roll with a roll diameter r (a).
  • Fig. 4A shows the belt 30 in an elongated or straight arrangement
  • Fig. 4B in a bent arrangement, when it wraps around a roll with a roll diameter r (a).
  • the belt rib 39.1 when the belt 30 is stretched, the belt rib 39.1 has a width a1 measured at the level of the rib foot, and the belt groove 39.2 has a width b1 measured at the height of the rib head.
  • the belt rib 39.1 when the belt 30 is bent, the belt rib 39.1 has a width a2 measured at the level of the rib base, and the belt groove 39.2 has a width b2 measured at the height of the fin head.
  • the width b2 becomes smaller than the width b1.
  • a2 becomes smaller than a1 as a result of the compressive stresses generated by belt deflection in this belt zone.
  • FIGS. 5A and 5B show arrangements in which the vertical projection of the axis 22 of the roller 20 intersects with the vertical projection of the axis 12 of the roller 10 and enclose an angle of 90 °.
  • the axis of rotation 12 of the first roller 10 would have to be rotated about an axis R to be parallel to the axis 22 of the second roller 20.
  • the belt 30 is rotated in the area between the rollers 10 and 20.
  • the textured belt main surface 33 is engaged with both the textured peripheral surface 13 of the roller 10 and the textured peripheral surface 23 of the roller 20.
  • the roller 20 rotates opposite to the roller 20 shown in Fig. 5A. Accordingly, in the area between the rollers 10 and 20, the belt 30 is rotated in the reverse direction than the belt shown in Fig. 5A 30. Also in the arrangement shown in Fig. 5B, it is achieved that the structured belt main surface 33 is engaged both with the textured peripheral surface 13 of the roller 10 and with the structured one Peripheral surface 23 of the roller 20th
  • FIG. 6 shows an elevator installation 100 according to the invention, comprising a drive unit 40, the first roller 10, which forms a traction sheave, the second roller 20, which forms a carrying roller / deflection roller, a further roller 50, the belt 30 and an elevator car 60
  • the belt 30 moves in the direction of arrow 31, the roller 10 according to arrow 11, the roller 20 in the opposite direction to the roller 10 according to arrow 21 and the roller 50 in the same direction as indicated by arrow 51 as the Roller 20.
  • the belt 30 is rotated between the first roller 10 and the second roller 20 by at least approximately 180 °, while it is not twisted between the second roller 20 and the third roller 50.
  • the structured belt surface 33 is always in contact with the peripheral surfaces 13 or 23 or 53 of the rollers 10, 20 and 50.
  • the elevator installation 100 comprises an elevator shaft 80, vertical guide rails 72, a counterweight 70 and a roller 71.
  • the belt 30 is connected at point 73 to one of the vertical guide rails 72 of the elevator installation 100 and runs around the counterweight support roller 71 around.
  • the other end of the belt 30 is secured in the region 74 of the upper end of the second vertical guide rails 72.
  • the structure of the belt 30 and the structures of the rollers 10 and 20 are optimally complementary when either the diameters and also the structures of the rollers 10 and 20 are the same or when the diameters of the rollers are different and then their structures are correspondingly different , But it is obvious that only the geometry, but also the material properties of the belt 30, set a lower limit for the roll diameter, which must not be fallen below.
  • Suitable widths B and thicknesses H of the belt 30, suitable wrap angles g, suitable diameters r of the rollers 10, 20 or suitable radii of curvature for the belt and suitable distances L1 between the rollers 10, 20 were determined partly mathematically, but in part also by tests.
  • Suitable belts 30 preferably have a width / thickness ratio (B / H) which is less than or equal to 10, that is, for example, a width B of 5 cm and, correspondingly, a thickness H of 0.5 cm.
  • Suitable wrap angles g are between 60 ° and 180 °. Preferably, these are between 90 ° and 180 °.
  • Suitable roll diameters r are between 6 cm and 20 cm.
  • the distance L1 between the two immediately successive rollers 10 and 20 should be at least 100 cm. Preferably, the distance L1 is between 100 cm and 300 cm.
  • the ratio between the distance L1 and the width B of a belt rotated by 180 ° about its longitudinal axis should not fall below a value of 30 and preferably should be in the range of 50. For smaller angles of rotation, these values are to be reduced proportionally.
  • Suitable material for a belt 30 having a textured belt main surface 33 suitable for use in an elevator system 100 are suitable rubbers and elastomers (plastics), in particular polyurethane (PU) and ethylene propylene copolymer (EPDM).
  • the belt 30 may be equipped with reinforcing inserts 38 oriented in the longitudinal direction of the belt and / or net-like reinforcing inserts.
  • twisted steel wire strands are suitable as reinforcement inserts 38 oriented in the longitudinal direction of the belt.
  • the strands 38 in the edge region can be more strongly twisted than the strands in the middle region of the belt 30.
