Definitions

  • the present invention relates to an elevator installation and in particular to an embodiment of a deflection roller in this elevator installation.
  • 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-like support means are not guided in grooves in the pulleys or traction sheaves, but the belt-like support means are substantially on the pulleys or traction sheaves on.
  • Suspension elements in elevator systems do not always run exactly perpendicular to an axis of deflection rollers or traction sheaves.
  • An occurrence of diagonal pull can be caused on the one hand by a construction, or on the other hand caused by inaccurate installation of the elevator system.
  • the suspension means By such oblique pulling the suspension means there is the danger that the support means slips laterally from a pulley or from a traction sheave of the drive. To prevent this, it is attempted to guide the belt-like support means laterally on pulleys or traction sheaves.
  • crowned deflection rollers are used, on which such support means are guided laterally to a certain extent.
  • belt-like support means In order to prevent lateral derailing of the belt-like support means, also raised side edges are used on the pulleys or traction sheaves.
  • belt-like support means with longitudinal ribs and L jossnutten on the traction surface of the support means and on the traction surface of the pulleys or traction sheaves are known, which interlock and thus ensure a lateral guidance of the belt-like support means on the pulleys or traction sheaves.
  • Such a device should also be inexpensive to manufacture and robust in use.
  • an elevator installation in which a belt-type suspension element is guided via a drive and via at least one deflection roller, wherein the deflection roller has an inner ring and an outer ring with a traction surface, and wherein the belt-like suspension element loads the deflection roller in a loading direction.
  • the loading direction is oriented substantially perpendicular to a bearing axis of the deflection roller.
  • the outer ring is movably mounted in the axial direction on the inner ring, so that when the loading direction is changed by an angle ⁇ , the outer ring also essentially inclines ⁇ by the angle. As a result, a vertical alignment of the loading direction to the traction surface is essentially maintained.
  • a deflection roller with an inner ring and an outer ring which is movable in the axial direction has the advantage that a possible diagonal pull of the belt-type suspension element is compensated by the Pully itself.
  • the loading direction is aligned at all times substantially perpendicular to the traction surface of the pulley.
  • an at least partially lateral derailment of the belt-like suspension element is effectively prevented by the deflecting roller, because the belt-like suspension element is always aligned essentially perpendicular to the traction surface of the deflecting roller.
  • Such pulleys have the further advantage that it requires no further adjustments in the elevator system. Such pulleys can therefore be used directly instead of conventional pulleys, without further adjustments in the elevator system would be necessary.
  • pulleys are to replace conventional pulleys in existing elevator systems.
  • Such pulleys also have the advantage that a certain systemic diagonal train in the elevator system is tolerable. By automatically neutralizing a possible diagonal pull through the pulleys a certain diagonal pull, be it caused by design or caused by inaccurate assembly can be tolerated.
  • the deflection roller may be formed, for example, as a sliding bearing or as a rolling bearing.
  • the deflection roller is designed as a rolling bearing, wherein rolling bodies are arranged between the inner ring and the outer ring.
  • rolling elements are, for example, roles or tons or balls in question.
  • the deflection roller is designed as a spherical roller bearing or as a self-aligning ball bearings.
  • the deflection roller is designed as a sliding bearing.
  • the inner ring and the outer ring are formed such that the outer ring is mounted in the axial direction movable on the inner ring.
  • the outer ring is tiltable about a center of the deflection roller. This has the advantage that the deflection roller can be mounted on a conventional Umlenkrollenachse, since the inner ring must have no freedom of movement relative to the Umlenkrollenachse.
  • the belt-like support means has a substantially flat traction surface, and the traction surface of the deflection roller is formed substantially spherical.
  • the belt-like support means is centered by the spherical deflection roller and thereby prevented from lateral displacement on the guide roller. This has the advantage that the inclination of the outer ring is improved in adaptation to a diagonal pull.
  • the belt-type suspension element has a traction surface which is complementary to the traction surface of the deflection roller. is formed.
  • the traction surface of the diverting pulley has at least one groove in the circumferential direction
  • the belt-like support means has at least one longitudinal rib on the traction surface. The longitudinal rib engages in an interaction of belt-like support means and pulley in the longitudinal groove.
  • the belt-like support means has six longitudinal ribs arranged parallel to one another, and the deflecting roller has six longitudinal grooves arranged parallel to one another in the circumferential direction. This has the advantage that a lateral guidance of the belt-like support means on the deflection roller is achieved, which improves an adaptation of the deflection roller to a diagonal train.
  • the deflection roller is arranged on a counterweight.
  • the deflection roller is arranged on the cabin.
  • two pulleys may be arranged on a cabin underside, wherein the belt-like support means is performed under the car.
  • Such pulleys can basically be used at different locations of an elevator installation and in different types of elevator installations.
  • Such pulleys can be used in elevator systems with counterweight and elevator systems without counterweight.
  • the deflection rollers can be arranged on a counterweight or a cabin, or else in a shaft.

  • the elevator installation 1 comprises a car 2, a counterweight 3, a drive 4 and a belt-like suspension element 5.
  • the belt-type suspension element 5 is fixed in the elevator installation 1 by a first suspension element fastening 7, guided via a counterweight deflection roller 10, via a traction sheave of the drive 4 guided over two Kabinenum- deflecting rollers 8 and secured by a second support means attachment 7 turn in the elevator system 1.

Abstract

L'invention concerne une installation d'ascenseur dans laquelle un moyen de support (5) du type courroie est guidé au moyen d'un entraînement (4) et d'au moins une poulie de renvoi (8, 10). La poulie de renvoi comporte une bague intérieure (11) et une bague extérieure (1) pourvue d'une surface de traction (15). Le moyen de support du type courroie sollicite la poulie de renvoi dans une direction de sollicitation (16, 16') orientée sensiblement perpendiculairement à un axe (9) de la poulie de renvoi. La bague extérieure est montée sur la bague intérieure de manière à pouvoir se déplacer dans la direction axiale, de sorte que lorsque la direction de sollicitation est modifiée pour suivre un angle a, la bague extérieure est également sensiblement inclinée selon l'angle a, ce qui permet de conserver sensiblement une orientation perpendiculaire entre la direction de sollicitation et la surface de traction.
