Definitions

  • the invention relates to a drive for an elevator for the vertical or inclined transport of people and loads, which has a mounted on a foundation base or with a controller and a brake that drives the drive wheel of the elevator for moving a driving cabin via a reduction gear mounted on the foundation base , wherein the drive wheel is coupled to the output shaft of the transmission.
  • Drives for elevators are known in various embodiments. They essentially consist of the same parts and include a motor that drives the elevator's drive wheel via a reduction gear. The drive also includes a brake and a control system for operating the elevator.
  • the driving wheel has to bear the loads that occur during the lift. Since these are usually quite considerable, the driving wheel is also powerful and. so heavily trained. For this reason, the output shaft of the reduction gear must be dimensioned accordingly large. So that the bending moments exerted by the drive wheel on the output shaft can be controlled, it is advisable not to place the drive wheel near the bearing of the output shaft, as is the case e.g. is known from U.S. Patent 4,422,531.
  • the arrangement of the drive wheel is achieved directly in the vicinity of the bearing of the output shaft in that either a bulge in the housing of the reduction gear is provided for preventing the brake or a special arrangement of the motor.
  • this solution has the disadvantage that the arrangement of the reduction gear with respect to the position of the drive wheel is always fixed.
  • the invention is therefore based on the object of further developing a drive for an elevator of the type described in such a way that an arbitrary distance can be maintained between the transmission and the drive wheel and regardless of this distance the housing of the transmission is not subjected to any stresses caused by the weight of the Cabin and possibly a counterweight is subjected to forces.
  • This object is achieved according to the invention in that on the housing of the reduction gear a support tube which is centered on the axis of the drive shaft of the gear is attached, which carries the drive wheel at its free end and is supported there with a support.
  • the system shown in FIGS. 1 and 2 has a drive 1 for an elevator with a drive wheel 2.
  • the drive 1 is composed of a motor 3, which can optionally be an electrical, thermal or fluid-driven motor, one Brake 4 and a reduction gear 5 together.
  • the reduction gear 5 is designed as a worm gear, but can also be a reduction gear of another type, for example a bevel gear.
  • the motor 3, the brake 4 and the reduction gear 5 are fastened to a foundation base 6 by adjusting screws 7, which are described in detail below with reference to FIG. 8.
  • the reduction gear 5 is designed as a worm gear, the worm 8 of which is coupled to the drive shaft 15 of the motor 3 by means of a rigid coupling 9 and the worm wheel 10 is connected to a drive shaft 11, which is inserted into a bore of the worm wheel 10 by means of a spline connection 12.
  • the output shaft 11 is not mounted in the housing of the reduction gear 5, but this function is performed by the multi-part, i.e. with two hub bodies 18 and a toothed body 19 formed worm wheel 10.
  • 10 plain bearing surfaces 13 are provided on the circumference of the worm wheel, which interact with bearing surfaces in the gear housing 14.
  • the reduction gear 5 can therefore also without an output shaft 11, e.g. to run in.
  • a support tube 21 is fixedly connected, which carries at its free end 22 a bearing socket 23 on which a roller bearing 24 is placed.
  • the hub body 25 is provided with an annular flange 26, by means of which the drive wheel 2 is mounted on the roller bearing 24.
  • a support 29 is attached to the free end 22 of the support tube, which is supported by a support profile 30 on an elastic Suspension, e.g. a cushion made of an elastomer is supported.
  • the support 29 surrounds the free end 22 of the support tube 21 or the bearing socket 23 with a cylindrical bore and can therefore be in various radial positions, e.g. can be fixed with an adjusting hub 36.
  • the reduction gear 5 is pivotally mounted about the axis of the screw 8.
  • the housing part which bypasses the screw 8 has cylindrical housing connections 376, on which support supports 38 are mounted.
  • the support supports 38 are each attached to a support 39 of the foundation base 6 by an adjusting screw 7; through this support, the reduction gear 5 can be pivoted about the axis 16 of the screw 8. This is necessary because the forces acting on the driving wheel 2 deform the suspension 35 of the support 29.
  • the drive wheel 2 being firmly connected to the gear housing 14 with the aid of the support tube 21, there are significant advantages. Since the driving wheel 2 or the forces acting on it can be supported softly on the suspension 25 via the support 29 and the transmission can follow any movements of the driving wheel 2 without constraint, no additional stresses occur on the reduction gear 5 due to the forces mentioned.
  • the reduction gear or the entire drive, which is attached to the foundation base 6, can also be softly cushioned, which is achieved by elastomer buffers 40 which are attached to claws 41 of the foundation base 6 and are supported on a base 43 by feet 42.
  • the motor 3 is connected to the reduction gear 5 through the rigid coupling 9.
  • the foundation base 6 has no machined support surfaces for the parts 3, 4 and 5, the rigid coupling of the motor 3 with the reduction gear 5 can be carried out with the aid of the adjusting screw 7.
  • the motor is screwed onto a support plate 44 which is fastened to supports 45, 46 with three adjusting screws 7.
  • the brake 4 is fastened on a support 47 and the reduction gear 5 on the supports 39 with adjusting screws 7.
  • the supports 39, 45, 46, 47 are attached to a base tube 48, e.g. welded on and together form the foundation base 6.
  • the formation of the adjusting screw 7 can be seen from FIG.
  • the adjusting screw 7 is composed of a threaded bolt 50 which carries two nuts 51, a clamping screw 52 which can be screwed into the threaded bolt 50 and with whose head 55 support washers 53 and intermediate spherical ring-shaped intermediate rings 54 are pressed onto a support ring 56.
  • the nuts 51 With the nuts 51, the adjusting screw 7 is fixed, for example, to one of the supports 39, 45, 46, 47 with the help of the nut 51.
  • the motor 3 is suspended with a vertical shaft 15 after the reduction gear has already been placed on the foundation base 6.
  • the motor 3 with the support plate 44 attached to it is now placed in its vertical position with the coupling half already placed on the coupling half of the likewise vertical worm shaft 17, whereupon the two coupling halves are placed on one another by lowering the motor and screwed together.
  • the motor 3 now stands vertically freely on the worm shaft and its shaft is exactly aligned with the worm shaft, provided that the coupling halves have neither radial runout nor deviations from the perpendicularity of the end faces.
  • two dial gauges which are at right angles to one another are placed on the shaft 15 of the motor 3 and set to zero. Now the three adjusting screws 7 are mounted and tightened so that the dial indicators do not deviate from their starting position or, if they differ, the adjusting screws 7 are loosened and tightened again until the starting position of the dial indicators is maintained again. If an electric motor is used as the drive, it is necessary to hold the stator housing in the magnetic central axis by means of shims because of the play that is present.
  • the design of the drive 1 with a drive wheel 2 arranged at a distance from the reduction gear 5 enables various adaptations to local conditions, as can be seen from FIGS. 4-7.
  • the drive wheel 2 can be used not only for a vertical elevator with a horizontal support tube 21, but also with an inclined support tube, e.g. for an inclined elevator.
  • the driving wheel 2 can also be supported laterally in side walls 58; the support 29 is designed with two arms and is supported in recesses in the side walls 58.
  • the drive i.e. the motor 3, the brake 4 and the reduction gear 5 are arranged vertically on a wall, the reduction gear 5 also being supported on a support 43. Since the reduction gear is pivotable about the worm axis 16, the drive wheel 2 can be pivoted and fixed in any position lying in a horizontal plane, see FIG. 6. In the arrangement according to FIG. 3, the drive wheel 2 can be pivoted in a vertical plane can be pivoted and fixed in any position.
  • FIG. 7 shows an arrangement of the drive 1, in which the support 24 is pivoted about the support tube axis and is fixed in an inclined position; such an arrangement may be necessary for reasons of space, for example.
  • the support 29 can also be supported on an inclined base 60, the position of the drive wheel or the support tube 21 also being able to be fixed in any position in a vertical plane in this case.
  • the lateral support of the driving wheel 2 in side walls can also be used.
  • the obliquely arranged support 29 according to FIG. 7 can also be used as an overhead arrangement, as shown in FIG. 3
  • the support according to FIG. 4 can also be replaced by an inclined support, which is supported in the same way in the side walls 58.
  • the drive 1 described has several advantages which increase the operational safety of an elevator.
  • the gear housing 14 is free of loads from the transported loads.
  • the distance between the reduction gear 5 and the drive wheel 2 can be chosen as desired.
  • only the output shaft 11 and the support tube 21 must have the desired length.
  • the parts of the drive 1 supported on the foundation base 6, ie the motor 3, the brake 4 and the reduction gear 5, remain unchanged, so that these parts can be assembled and stored.
  • the support 29 can with can be cushioned by a soft cushion 35 without causing damaging effects on the reduction gear 5.
  • the foundation base 6 can be softly cushioned with elastomer buffers 40.
  • the reduction gear 5 and the motor 3 can be coupled rigidly to one another, although no machined surfaces are provided on the foundation base 6.
  • the brake 4 can also be mounted exactly centrally on the foundation base 6.
  • the foundation base 6 can also be prefabricated, the required parts of the drive 1 being able to be mounted with the aid of adjusting screws 7.
