Description

    TECHNICAL FIELD
  • The present invention relates to an elevator hoisting machine for raising and lowering an elevator car by means of a main rope.
    • BACKGROUND ART
  • In conventional elevator hoisting machines, a drive sheave being a separate member from a rotating shaft is fixed to the rotating shaft, which is rotated by a drive motor. Rope grooves are formed in the drive sheave, and a main rope for suspending an elevator car is wound around the drive sheave.
    Such devices can be found disclosed in, for example, EP 1 010 660 A1 or US 5,982,060 .
  • The drive sheave is required to rotate smoothly while constantly bearing the rope load and generating traction. Hence, it is necessary for the drive sheave to have sufficient hardness and strength, and to be manufacture precisely. Furthermore, since a large hoisting torque is transmitted from the drive motor, the drive sheave is fitted to the rotating shaft firmly by methods including shrink fitting, using keys, etc. Consequently, conventional drive sheaves are constituted by thick-walled, high-strength castings, hindering reductions in the size and weight of elevator hoisting machines.
  • Furthermore, when using a main rope composed of a steel rope, D/d (drive sheave diameter/main rope diameter) is required to be equal to or greater than 40 from the viewpoint of flexibility, etc., of the steel rope, thereby also enlarging the drive sheave.
  • In answer to this, main ropes composed of a synthetic fiber rope have been achieved in recent years. Since synthetic fiber ropes of this kind have high coefficients of friction and superior flexibility, it is possible to lower D/d to around 25, making reductions in the size of the drive sheave possible.
  • However, particularly in high-capacity hoisting machines used in large elevators, since the diameter of the rotating shaft is large, if the diameter of the drive sheave is reduced, the difference between the diameter of the drive sheave and the diameter of the rotating shaft is also reduced. In other words, if the diameter of the drive sheave is reduced to a minimum, the drive sheave becomes thin-walled, making manufacture and fitting of the drive sheave onto the rotating shaft difficult. Hence, from the viewpoint of manufacture and assembly, there is a risk that reductions in the size of the drive sheave, and in turn reductions in the size and weight of the hoisting machine, will be limited.
    • DISCLOSURE OF THE INVENTION
  • The present invention is defined by the independent claims, the preambles of which are based on JP-A-09142761 .
  • The present invention aims to solve the above problems and an object of the present invention is to provide an elevator hoisting machine facilitating assembly and also enabling reductions in size and weight by reducing the number of parts.
  • According to one aspect of the present invention, there is provided an elevator hoisting machine including: a bearing mount; a rotating shaft rotatably supported in the bearing mount, rotation of the rotating shaft raising and lowering an elevator car by means of a main rope; a drive motor for rotating the rotating shaft; and a braking device for braking the rotation of the rotating shaft, wherein a main rope winding portion provided with a rope groove into which the main rope is inserted is formed integrally on the rotating shaft.
    • BRIEF DESCRIPTION OF THE DRAWINGS
    • Figure 1, useful for understanding the invention, is a perspective showing a construction of a main rope;
    • Figure 2 is a side elevation showing an elevator hoisting machine according to Embodiment 1 of the present invention;
    BEST MODE FOR CARRYING OUT THE INVENTION
  • Preferred embodiments of the present invention will now be explained with reference to the drawings.
  • Figure 1, which is useful for understanding the invention, is a perspective showing a construction of a main rope 7. In the figure, an inner strand layer 24 having a plurality of inner strands 22 and filler strands 23 disposed in gaps between these inner strands 22 is disposed around a core wire 21. Each of the inner strands 22 is composed of a plurality of aramid fibers and an impregnating material such as a polyurethane or the like. The filler strands 23 are composed of a polyamide, for example.
  • An outer strand layer 26 having a plurality of outer strands 25 is disposed around an outer circumference of the inner strand layer 24. Each of the outer strands 25 is composed of a plurality of aramid fibers and an impregnating material such as a polyurethane or the like in a similar manner to the inner strands 22.
  • A friction-reducing coating layer 27 for preventing abrasion of the strands 22 and 25 due to friction among the strands 22 and 25 is disposed between the inner strand layer 24 and the outer strand layer 26. A protective coating layer 28 is also disposed on an outer circumferential portion of the outer strand layer 26.
  • A synthetic fiber rope of this kind has a high coefficient of friction compared to a steel rope and is superior in flexibility
  • In an elevator hoisting machine constructed as will be described below with respect to Embodiments 1 and 2 of the invention, since the main rope winding portion 34a is formed integrally on the rotating shaft 34 without using a separate drive sheave, the number of parts can be reduced, and the need for shrink fitting and a key work is eliminated, enabling assembly to be facilitated. Furthermore, the diameter of the main rope winding portion 34a is minimized, enabling overall reductions in size and weight.
  • An elevator hoisting machine of this kind can be used with a main rope composed of a steel rope if a sufficient diameter is ensured at the main rope winding portion 34a, but the elevator hoisting machine of this kind is more effective when used with the main rope 7 composed of the synthetic fiber rope in order to enable reductions in size and weight.
  • Furthermore, since the main rope winding portion 34a is composed of the same material as the rotating shaft 34, the rope grooves 34b are easily worn if the steel rope is used. In contrast to this, the rope grooves 34b are less likely to become worn in the case of the synthetic fiber rope. In addition, since the synthetic fiber rope has a high coefficient of friction, it is not necessary to provide undercut grooves to increase friction inside the rope grooves 6b, and from these viewpoints also, the elevator hoisting machine of this kind is more effective when used with the main rope 7 composed of the synthetic fiber rope.
  • Furthermore, since the end surface of the main rope winding portion 34a integrated with the rotating shaft 34 can be used to mount the brake disk 12, the brake disk 12 can be fixed to the rotating shaft 6 simply and firmly.
    • Embodiments 1
  • Figure 2 is a side elevation showing an elevator hoisting machine according to Embodiment 1 of the present invention. In the figure, a bearing mount 32 is fixed on a base 31. A bearing 33 is supported in the bearing mount 32, and an intermediate portion of a rotating shaft 34 is rotatably supported by means of this bearing 33. The rotating shaft 34 is composed of a carbon steel, for example.
  • A main rope winding portion 34a is formed integrally on a first end portion of the rotating shaft 34, a main rope 7 being wound around the main rope winding portion 34a. A plurality of rope grooves 34b into which the main rope 7 is inserted are disposed on the main rope winding portion 34a.
  • A drive motor 35 for rotating the rotating shaft 34 includes: a case 36 fixed to the bearing mount 32; a stator 37 fixed inside this case 36; and a rotor 38 mounted to the rotating shaft 34. The rotating shaft 34 is rotated directly by the drive motor 35 without intermediation by gears. Furthermore, in this example, the type of drive motor 35 used employs a permanent magnet in the rotor 38. A bearing 39 for rotatably supporting a second end portion of the rotating shaft 34 is held in the case 36.
  • A braking device 11 for braking rotation of the rotating shaft 34 includes: a brake disk 12 rotated together with the rotating shaft 34; and a braking device body 13 for braking rotation of the brake disk 12. The brake disk 12 is fixed to the rotating shaft 34 by being joined to an axial end surface of the main rope winding portion 34a. Furthermore, the brake disk 12 is fixed to the rotating shaft 34 by means of a plurality of bolts 14 extending parallel to an axial direction of the rotating shaft 34 and engaged in the end surface of the main rope winding portion 34a.
  • Hence, the main rope winding portion 34a may be formed in one end portion of the rotating shaft 34, effectively enabling an overall reduction in size when the number of rope grooves 34b is small.
  • Moreover, in Embodiments 1 a gearless type of hoisting machine is shown, but the present invention can also be applied to a geared type of hoisting machine in which a driving force from the drive motor is transmitted to the rotating shaft by means of a speed reduction mechanism.
