Definitions

  • the invention relates to a drive for hoists, which is used for lifting loads.
  • Hoist drives are e.g. B. used in lifts or winches.
  • the installation length available for the individual hoist drive is generally limited by the elevator shaft and the maintenance space required therein. Since hoist drives can also be installed between the elevator shaft and the cabin, the radial installation space for the diameter of the traction sheave is limited, which therefore must not exceed a maximum value. Within these limits, the hoist drive with a mechanical reduction gear in the form of a planetary gear with a bearing for the traction sheave, a drive unit and a safety brake is to be accommodated.
  • a hoist drive is a compact drive unit that can be installed and serviced in a confined space. It should be possible to change the traction sheave without much effort.
  • a hoist drive is known from PCT / EP 95/03879, which is assembled from independent, removable units. These consist of a planetary gear with a traction sheave, a brake housing designed as a stand, in which a safety brake is housed, and a drive unit. With this hoist drive, the structure of the planetary gear has a disadvantageous effect on the overall length of the drive, since the drive pulley is mounted next to the planetary stages.
  • the safety brake is housed in a separate housing, which extends the overall length.
  • the invention has for its object to provide a compact hoist drive, which is characterized by a short length, low cost, low weight and a small number of components.
  • a stage with step planets is used for the required gear ratio of approximately 20, in which a higher gear ratio is additionally achieved by the planet carrier of the planetary stage being connected to the drive pulley.
  • the step with step planets can be helically toothed, which improves the vibration or noise behavior. If the toothing of the inner central wheel with the stepped planet has a simultaneous sequence of engagements, the vibration or noise behavior is further improved.
  • the teeth of the planetary stage can be designed as helical teeth, the geometry of which can be selected so that the planetary stage does not generate any axial forces that would have to be absorbed by the planet carrier. Toothing with straight-toothed wheels is also possible.
  • the bearing of the traction sheave is placed above the planetary stage, which further shortens it is, the raceway of the rollers of the bearing is the radially outer edge of the ring gear.
  • An optimal bearing design of the traction sheave bearing enables the bearing arrangement in the middle under the power line of the traction sheave.
  • the bearing can also be attached next to the planetary stage.
  • the outer ring of the bearing can be made in one piece, thereby reducing the number of parts, or in two parts.
  • the housing of the drive unit is designed with a stand that allows the hoist drive to be installed at the location provided, the mechanical transmission and the safety brake are each attached to the drive unit on one side. This eliminates the housing part with stand foot, which would surround the brake.
  • the ring surrounding the traction sheave bearing also serves as a support for the traction sheave. This enables a traction sheave to be changed without having to dismantle the gearbox. It is also possible to form the traction sheave in one piece with the ring, or to form the planet carrier, the ring and the traction sheave in one piece.
  • the single figure shows a cross section through a hoist drive 1.
  • the hoist drive 1 shown consists of a drive unit 2, to which a mechanical planetary gear 4 and a safety brake 11 are connected.
  • the ring gear 6 of the planetary gear 4 is connected in a rotationally fixed manner to the housing 8 of the drive unit 2 by means of a screw connection 7 and Ren edging is a bearing 9, which can be formed with a one-piece outer ring which is arranged between a ring 10 and the rollers of the bearing 9.
  • the traction sheave 12 is arranged, which is rotatably connected to the planet carrier 13, which forms the outer boundary of the planetary gear 4.
  • the ring 10 and the traction sheave 12 can also be made in one piece.
  • the inner central wheel 14 of the planetary gear 4 is rotatably connected to the output shaft 15 of the drive unit 2.
  • the inner shaft 16 of the safety brake 11 is rotatably connected to the output shaft 15 of the drive unit 2.
  • the inner central wheel 14, the inner shaft 16 of the safety brake 11 and the output shaft 15 of the drive unit 2 can also be made in one piece.
  • the radially outer peripheral wall of the ring gear 6 is provided with a sealing ring 17 for liquid-sealing separation.
  • the radially inner peripheral wall of the housing 8 of the drive unit 2 on the side facing the planetary gear 4 is provided with a sealing ring 18 for the liquid-sealing separation of the planetary gear 4 and the drive unit 2.
  • the stand base 3 is either connected in one piece to the drive unit 2 or attached to it.
  • the toothing of the planetary gear 4 is preferably designed as a helical toothing, the planets of which are designed as step planets 5.
  • the helical toothing of the stepped planet 5 can be designed such that the stepped planet 5 does not generate any external axial forces.

Abstract

Un entraînement pour appareil élévateur (1), notamment pour entraîner un ascenseur, comporte une unité d'entraînement (2), un engrenage planétaire (4) et un frein de sécurité (11), l'engrenage planétaire (4) étant situé sur un côté de l'unité d'entraînement (2) et le frein de sécurité (11) sur le côté opposé. L'engrenage planétaire (4) comporte un entraînement planétaire avec des satellites étagés (5), dont la denture est hélicoïdale, de sorte que les satellites étagés (5) n'exercent pas de forces axiales extérieures, et dont la couronne (6) est fixée, de manière à ne pas pouvoir tourner, sur le carter (8) de l'unité d'entraînement (2). La roue centrale intérieure (14) de l'entraînement planétaire est entraînée par l'arbre de sortie (15) de l'unité d'entraînement (2), le porte-satellites (13) est fixé, de manière à ne pas pouvoir tourner, sur le disque d'entraînement (12), lequel est disposé, par l'intermédiaire d'une bague (10) et d'un palier (9) muni d'une bague extérieure monobloc, sur une couronne (6) dont le porte-satellites (13) constitue la limite extérieure de l'engrenage planétaire (4). Le carter (8) de l'unité d'entraînement (2) comporte un pied (3), et le frein de sécurité (11) est fixé, de manière à ne pas pouvoir tourner, sur le carter (8) de l'unité d'entraînement (2).
