Definitions

  • the invention relates to a drive for an elevator installation according to the preamble of the independent claim.
  • An elevator system consists of a cabin for receiving cargo or persons and a counterweight, or a second cabin, which are connected to each other by means of a support and propellant means of a drive.
  • the drive of the elevator system aims to drive the driving and suspension means and thus a reciprocal lifting and lowering of the car and counterweight.
  • the drive consists of the main components traction sheave, motor and brake.
  • the traction sheave receives the carrying and blowing agent and transmits by means of positive or frictional connection driving forces on the carrying and blowing agents.
  • the engine in turn drives the traction sheave and the brake brakes the traction sheave.
  • Motor, brake and traction sheave are accordingly connected to each other in terms of force and torque.
  • a drive to an elevator in which a motor drives traction sheaves by means of a drive shaft and the traction sheaves are braked by a brake.
  • the traction sheaves are arranged, in a preferred embodiment, between the engine and the brake unit.
  • the traction sheaves drive flat belts. This allows the use of small pulley diameters.
  • the drive can be made small and compact. The small dimensions and compact design of this drive result in new challenges. Brake and motor housings must be connected to each other in terms of force and torque. The connection to the brake must be safety-compliant, ie at least form-fitting. The small dimensions should be maintained.
  • the object of the present invention is to provide a drive to an elevator installation, which has small external dimensions, is designed in accordance with safety and can be produced inexpensively.
  • the invention relates to a drive for an elevator system, which drives a car and a counterweight via a support and propellant and the drive includes a traction sheave, which is driven by a drive shaft of a motor and braked by a brake, wherein drive shaft, motor and brake assembled with a support to a unit.
  • the support forms the common support structure of the drive to which, depending on the embodiment, parts of the drive are arranged. It allows the attachment of the drive in the building.
  • the support can be an integral part of the engine or the brake or it can be a housing which receives, for example bearings of the drive or surrounds the traction sheaves.
  • the brake is connected by means of pins with the housing of the motor or with the support or with another brake. That is, the torque transfer from the brake to the support or the housing of the engine or to a next brake by means of pins.
  • Next include the housing of the motor or the support, and the brake, or a fixed part of the brake, a pin hole.
  • the pin is inserted in the pin bore of the motor, or the support.
  • the brake is secured by means of the brake-side pin bore on the corresponding pin.
  • the brake is thus torque-resistant, or positively connected to the engine or the support.
  • the pins and the connection points at brake and housing, or support are easy to produce. As a result, a cost-effective and space-saving connection of the brake in the drive is possible, which also meets the safety requirements, which are placed on a positive connection.
  • Fig. 1 shows a drive for an elevator installation with the main characteristic of the invention.
  • the drive 1 has one or more drive pulley zones 3 and a drive pulley zone 3 comprises at least one traction sheave 2.
  • the traction sheave 2 serves to receive a carrying and driving means 6 which connects a car of the elevator with a counterweight or a second car.
  • the traction sheave 2 is integrated in the drive 1 shown in a drive shaft 7.
  • a motor 4, which drives the drive shaft 7, is subsequently arranged on the traction sheave 2.
  • a brake 5, or a fixed part of the brake as in Fig. 1 . 2 and 3 represented by means of bolts, pin or pin 11 connected to a support 8.
  • the attachment of the brake 5 is carried out taking into account the space available and an optimal power flow either to a housing 12 of the motor 4, as in Fig. 3 shown or to the support 8, as in the Fig. 1 and 2 shown.
  • the use of pin 11 forms a cost-effective and space-saving design for mounting the brake fifth
  • the pin 11 is inserted at one end into a mating pin hole 30 of the support 8 or the housing 12, or the end of the pin 11 is in the support 8, or in the housing 12, sunk.
  • the pin 11 defines a predetermined distance between the brake 5 and the support 8, and the housing 12.
  • a brake disc 22 and a brake pressure plate 23 are arranged.
  • the brake disk 22 is non-positively connected to the motor shaft 15 or the drive shaft 7 and rotates with the rotational speed of the motor 4.
  • the brake pressure plate 23 is attracted in the operating position of the drive 1 to the housing of the brake 5, for example.
  • the pins 11 and the connection points in the brake 5 and the housing 12 of the motor 4, or support 8 are in the whole considered easy to manufacture. As a result, a cost-effective and space-saving attachment of the brake 5 in the drive 1 is possible, which also meets the safety requirements, which are placed on a positive mounting the brake to the engine.
  • a two-circuit brake can be executed, which can also be used for safety-related functions.
  • the drive 1 consists in a preferred embodiment of two spaced apart blowing zones 3, wherein a blowing zone 3, one or more traction sheaves 2 may include.
  • the motor 4 and / or the brake 5 are arranged outside the two blowing zones 3, and a main bearing 25 is arranged between the two blowing zones 3, so that a main supporting force of, generated by the support and drive belt 6, carrying capacity, essentially, means the main bearing 25 is introduced into a support structure.
  • the drive can be made compact and inexpensive.
  • the belts are flat according to the design of the traction sheave 2, that is smooth, or they have a longitudinal profiling, for example in the form of V-ribs or they have a transverse profile, for example a tooth shape.
  • Fig. 1 and Fig. 2 Motor shaft 15, drive shaft 7 and traction sheave 2 are made in one piece. Alternatively, only the motor shaft 15 and the drive shaft 7 may be made in one piece, or the drive shaft 7 and the traction sheave 2 are made in one piece. The production as individual separate parts is of course possible. The choice of suitable embodiment is made at the choice of the manufacturer.
  • the brake 5 can also be arranged on the motor-side end of the drive shaft, for example, outside the support 28.
