Definitions

  • the invention relates to a traction sheave elevator with an elevator car that runs along Guide rails can be moved in an elevator shaft, with one also at least a rail guided counterweight as well as with a double at least from one Bearing shaft having drive motor, a traction sheave for hanging the Elevator car and the counterweight serving suspension means or ropes and a brake formed Drive, which is arranged in the upper region of the elevator shaft, the Drive for its attachment has a supporting part that has a mounting foot.
  • traction sheave lifts are already known and have proven themselves.
  • DE 100 64 850 C2 describes such a traction sheave elevator, in which the drive in Area of the elevator shaft is arranged.
  • the elevator car should have as few motor drives as possible Cause operating noise.
  • a drive located in the elevator shaft should be be as small as possible in order to keep the dimensions of the shaft itself as small as possible can.
  • the support part in a position in use a vertical plane arranged bearing flange for fastening the motor housing and a first bearing for the shaft has that the traction sheave and the rotor of the drive motor are connected by the common, double-bearing shaft and on different Sides of the support member and the first bearing and that the second bearing are spaced too the bearing flange is arranged in the motor housing.
  • the bearing in the bearing flange can thereby absorbing most of the forces on the drive and traction sheave attack.
  • the second bearing is on the side facing away from the traction sheave of the drive motor is less loaded, so that the housing of the drive motor is relatively be thin-walled and light and can consist of a material so that a low-noise cooling of the drive motor is possible and the motor housing with the second bearing is largely freely suspended only with one end face on the bearing flange can be.
  • Motor housing is provided with cooling fins on the outside. Enlarge such cooling fins the surface of the engine case, which is the amount of passively radiated to the outside or heat dissipated from the air flowing around the motor housing.
  • the air surrounding the motor housing and moved by the moving elevator car can flow around the motor housing particularly easily and thereby cool when the on the Motor housing provided cooling fins protrude in a substantially radial direction and at least partially on the circumference of the motor housing, in particular on the underside of the Revolve around the motor housing.
  • the cooling fins are therefore parallel to that of the vertical Movement of the elevator car caused and also directed vertically Main flow direction of the air in the elevator shaft aligned and can be from this air flowing essentially upwards or downwards in the elevator shaft and thereby be cooled.
  • first bearing is larger in accordance with its higher load and / or is dimensioned stronger than the second bearing. This allows them to match their Load dimensioned bearing of the drive motor the forces acting on the shaft absorb it accordingly, which prevents uneven wear can and the durability of the drive motor increases.
  • bearings rolling bearings and at least the first bearing Roller or double ball bearing is or is formed from two adjacent bearings. Rolling and Ball bearings require little maintenance and are long-lasting.
  • An expedient design of the supporting part with the fastening foot can consist in that the mounting foot of the support part seen from the storage level to below the Traction sheave, its horizontal dimension in the use position less than is the diameter of the traction sheave. This can cause the traction sheave and the move the rope without hindrance, even if the fastening foot is in the axial direction protrudes under the traction sheave.
  • the mounting foot can be a sufficiently large one Offer mounting surface for absorbing the forces acting on the traction sheave.
  • the mounting foot is also below the bearing extends at least partially under the motor housing. As a result, from that Fastening foot further forces can be transmitted on this side of the support part without that To have to use the motor housing.
  • the mounting foot can go as far below that Motor housing protrude that it provides the greatest possible stability, but at the same time that Airflow around the motor housing is hampered as little as possible.
  • the drive motor is fanless or fanless. Because of the design of the motor housing and the Mounting foot already cooling the drive motor by the air flowing past may be sufficient, further ventilation of the drive motor is possible noise-causing fans or fans can be dispensed with. In addition to the Noise reduction also results in space and weight savings.
  • the shaft of the drive motor is perpendicular to one
  • the outer wall of the elevator car runs together with an opposite one
  • the shaft wall forms an intermediate space in which the ropes and the counterweight of the Elevator are arranged and movable and that the traction sheave above that of the Shaft wall and the outer wall of the elevator car formed space is.
  • the motor housing with at least one Part of its longitudinal extent extends over a car roof of the elevator car. This is the drive motor is relatively free and light for the air moved by the elevator car accessible or directly exposed to this air flow.
  • this freely flowable arrangement of the drive motor can be that the mounting foot directly or indirectly on a guide rail of the counterweight and a guide rail of the elevator car is attached. It can be used for indirect Attachment be useful if on only one rail of the counterweight and only one Rail of the elevator car is a platform or console on which the Mounting foot of the drive is attached. This platform can be on the top ends of the Rails of the counterweight or the elevator car can be arranged.
  • the motor housing can consist, for example, of a material which Heat conducts particularly well and also has a sound-absorbing effect to reduce the operating noise of the Reduce drive motor.
  • the brake in particular a multi-circuit Disc brake, at the end of the drive motor opposite the traction sheave is grown.
  • a brake can operate quietly and is largely maintenance-free his.
  • the arrangement at the end of the drive motor opposite the traction sheave can be easily implemented, also because there is enough space for the brakes is available.
  • an encoder system for controlling a gearless three-phase machine is arranged as a drive motor. This allows a gearless drive motor Three-phase motor can be used, which simplify the structure of the drive and the Can reduce the space requirement of the drive.
  • the elevator car and the counterweight have a multiple cable suspension, preferably have a cable suspension in a ratio of 2: 1.
  • a traction sheave elevator designated as a whole by 1, is vertical in FIG. 1 Elevator shaft 14 shown in a view from the side. There is an elevator car 2, which can be moved up and down along guide rails 3 in the elevator shaft 14 is recognizable and a counterweight 4, which is suspended with ropes 11 and on Guide rails 5 is guided and 2 movements in opposite directions to the elevator car. Also shown is a drive which has a drive motor 6 and a brake 12 has, and a traction sheave 10 fastened thereon for hanging the elevator car 2 and the counterweight 4 with the ropes 11. The drive is in the upper part of the Elevator shaft 14 arranged, the drive by means of a support member 8 in still is descriptively held together and stored.
  • the supporting part 8 has a fastening foot 8a and a Position of use in a vertical plane arranged bearing flange 8b for attachment of the motor housing 7 and a first bearing 8c for a double-bearing shaft 9 and that the traction sheave 10 and the rotor 6a of the drive motor 6 by the common Shaft 9 are connected and are on different sides of the support member 8.
  • the wave 9 is in this case through the first bearing 8c in the bearing flange 8b and through a second bearing 13 Distance to the bearing flange 8b on the side facing away from the drive pulley 10 Side of the drive motor 6 mounted.
  • This arrangement means that the support part 8 has the entire axle load and that there located first bearing 8c takes up most of the bearing load, while the Motor housing 7 contains the second bearing 13 for a correspondingly lower bearing load.
  • the bearings 8c and 13 are also corresponding to these different loads dimensioned differently, the first bearing 8c significantly larger and stronger than the second Camp 13 is.
  • the bearings 8c and 13 are roller bearings, the first Bearing 8c is designed as a roller bearing and the second bearing 13 as a ball bearing.
  • FIG. 4 also shows that the motor housing 7 has cooling fins 7a on the outside, which in FIG protrude in the radial direction and in the embodiment shown parallel to each other revolve around the entire circumference of the motor housing 7 and thus to that in the elevator shaft 14 are aligned with the elevator car 2 moving air.
  • the one at the vertical directed up and down movement of the elevator car 2 arise according to the respective movement of air flows directed in the same direction, either air upwards or is moved down. So the motor housing 7 with each movement of the elevator car 2 and thus especially during the operation of the drive motor 6 constantly changing Air flows around and is therefore cooled.
  • the mounting foot 8a of the support member 8 is from the Seen from the storage level to below the traction sheave 10 (Fig. 4), being his horizontal dimension in use position less than the diameter of the traction sheave 10 (Fig. 3).
  • the drive is supported on the side of the traction sheave 10 and at the same time the ropes 11 running on the traction sheave 10 can move freely.
  • the mounting foot 8a extends below the bearing 8c partially under the motor housing 7, as shown in FIG. 4. So the drive on the side of the Motor housing 7 are supported without the airflow around the motor housing 7 and the cooling fins 7a is disabled.
  • Fig. 2 shows a view of the elevator shaft 14 from above that the longitudinal central axis of the Drive motor 6 and the cutting disc 10 approximately parallel to the side walls 14a of the Elevator shaft 14 and are arranged approximately centrally between these side walls 14a.
  • the shaft 9 of the drive motor 6 runs, which is approximately the longitudinal central axis of the Drive motor 6 corresponds, at right angles to an outer wall 2a of the elevator car 2, which forms an intermediate space together with an opposite shaft wall 14b, in which the ropes 11 and the counterweight 4 of the elevator 1 are movable.
  • the Traction sheave 10 is arranged above this space, so that on the Traction sheave 10 running ropes 11 and the counterweight 4 held on the ropes 11 directly are located below the traction sheave 10 in the space. It can be seen that the traction sheave 10 is relatively close to or opposite the shaft wall 14b is located, so that the space for the ropes 11 and the counterweight 4 accordingly can be narrow.
  • the brake 12 is at the end of the drive motor 6 opposite the traction sheave 10 arranged, as Fig. 4 shows.
  • the brake can in particular be a multi-circuit Be disc brake.
  • a Encoder system 15 for controlling a gearless three-phase machine as a drive motor arranged.
  • Fig. 1 shows that the elevator car 2 and the counterweight 4 a multiple rope suspension and thus by the drive motor 6 for the movement of the elevator car 2 and the counterweight 4 force less than a simple one Rope suspension can be.
