Definitions

  • the invention relates to a drive unit for an elevator, comprising a drive and a traction sheave and a braking device integrated in the traction sheave for fixing the traction sheave.
  • the drive consists of a shaft mounted twice on a housing, on which at one end an electric motor and at the other end a traction sheave is arranged, are guided over the elevator car and counterweight driving ropes.
  • a brake drum is supported on the shaft, engage the brake shoes.
  • a disadvantage of the known device is that an additional brake drum is necessary for braking.
  • the drive unit therefore builds longer, especially on the traction sheave side.
  • a drive arranged at the counterweight of an elevator installation has become known, which is flat.
  • the gearless motor is integrated in the traction sheave, wherein the traction sheave is arranged peripherally on the disc-shaped rotor of the motor and is supported centrally by means of the rotor.
  • the disc-shaped rotor also serves as a brake disc of the braking device of the drive, wherein the rotor is formed in the braking area as a braking surface.
  • a disadvantage of this device is that the braking device must be located close to the rotor bearing due to lack of space, with the result that the bearing is exposed to excessive heating.
  • the invention aims to remedy this situation.
  • the invention as characterized in claim 1 solves the problem of avoiding the disadvantages of the known device and to provide a drive unit which is suitable for a machine room-less elevator system, in particular for installation in the shaft head.
  • 1 designates a hoistway limited by shaft walls 1.1, in which an elevator car 2 can be moved.
  • the elevator car 2 is guided by means of car guide rails 3.
  • a counterweight 4 is guided in the elevator shaft 1 by means of counterweight guide rails 5.
  • An existing drive 6 and traction sheave 7 drive unit is arranged in the shaft head 1.2 on a counterweight guide rail 5 and on a support rail 5.1.
  • a support cable 8 connects the counterweight 4 with the elevator car 2, wherein a sub-loop 9 is provided on the elevator car.
  • the one end of the support cable 8 is fastened to a first cable fix point 10 and then passes over a counterweight 4 arranged on the first pulley 11, further on the traction sheave 7, on the existing from a second pulley 12 and third pulley 13 Unterschlingung 9 and finally a second rope set point 14.
  • the rope fixing points 10,14 are arranged for example on the shaft ceiling, not shown.
  • the elevator car 2 is shown standing on the top floor.
  • the traction sheave 7 is arranged centrally above the one car guide rail 3, wherein the drive 6, viewed from above, projects beyond the elevator car 2.
  • Fig. 2 shows the example gearless drive 6 with the traction sheave 7 in three-dimensional representation.
  • the drive 6 consists of a housing 15 in which a motor 16 with stator 17 and rotor 18 is arranged. A trained as a pedestal 15.1 housing extension is used to attach the drive 6 to the rails 5, 5.1.
  • a shaft 19 mounted on the housing 15 transmits the rotational movement of the rotor 18 to the traction sheave 7.
  • the shaft 19 is mounted on the housing 19 by means of a first bearing 20 and a second bearing 21.
  • a pulse generator 22 is arranged, which measures the rotational movement of the shaft 19.
  • the traction sheave 7 is designed as a closed hollow cylinder on one side, wherein the closed side with the shaft flange 23 is connectable.
  • rope grooves 25 are arranged, which serve to guide the support cables 8 and the power transmission from the traction sheave 7 on the support cables 8.
  • the shell inner surface of the traction sheave 7 is formed as a brake drum 26, on the actuatable brake shoes 27 the Stop drive 6.
  • Fig. 3 shows a section through the drive 6 in the region of the brake shoes 27, wherein the traction sheave 7 is not shown.
  • the brake shoe 27 is arranged at one end articulated on a first housing bolt 31 and the other end to a brake lever pin 28.1 articulated to the brake lever 28.
  • the brake lever 28 has a lever pin 32.1, on which a driver 32 engages, wherein the driver 32 is arranged on a brake axle 33.
  • the brake lever 28 is connected to a first actuating pin 29.
  • the first actuating pin 29 can be actuated by means of the actuator 30, which consists of a first spring package 34, a magnet 35 arranged on the housing 15 and an armature plate 36.
  • the brake shoe 27 can also be mechanically remotely operated by means of the driver 32, wherein the driver 32 arranged on the brake axle 33 carries out a rotational movement and thereby causes the lever bolt 32.1 or the brake lever 28 to move linearly.
  • the brake axle 33 is supported on the housing 15 and on a motor-side shield 37.
  • the brake axle 33 is rotatable by means of an axle lever 38, wherein the two axle lever 38 are contractible at the free ends, for example by means of a cable pull, whereby the brake is mechanically remote-controlled or mechanically ventilated from the outside, whereby the elevator car 2 driven in an emergency to the next floor can be.
  • the first, mainly provided for braking force adjustment spring package 34 supports the spring force of the second spring pack 39.
  • the main brake force acts directly on the brake shoe 27 in the radial direction.
  • each brake shoe 27 is a brake lever 28, a driver 32, a brake axle 33, an axle 38, a first actuating pin 29 and an actuator 30 is provided.
  • the braking device may be designed as a disc brake, wherein the brake drum 26 has a brake disc, attack on the brake pads.
