Definitions

  • the present invention relates to a drive machine for an elevator installation and a method for assembling a drive machine according to the definition of the patent claims.
  • the font WO99 / 43593 shows a drive machine with two drive pulleys for belts.
  • the traction sheaves are arranged in the outer areas of the cabin dimension, at least in the respective outer third of the cabin dimension corresponding to the alignment of the drive axis, or outside the cabin.
  • the traction sheaves are arranged on both sides at the end of the drive machine.
  • US2002 / 0070080A1 shows another example of a prime mover with two traction sheaves.
  • One object of the present invention is to provide a drive machine and a method for assembling the same, which optimizes the flow of force and thus keeps the requirements on the adjacent construction low and minimizes the space required for the drive machine.
  • the drive machine should also allow a flexible arrangement in the shaft.
  • the suspension and propellant strand should be divided into two strands.
  • the invention relates to a drive machine for an elevator installation with a car and counterweight and a shaft.
  • Carrying and propellant means connect the cabin to the counterweight.
  • the suspension and propellants are referred to below as propellants.
  • the propellants are routed through the prime mover.
  • the propellants are driven by a drive shaft in the prime mover.
  • the zones of the drive shaft which transmit the force to the propellants are referred to below as propellant zones.
  • the car and the counterweight are guided by means of car guide rails or counterweight guide rails.
  • the drive shaft has two drive zones that are spaced apart from one another.
  • the blowing zones are adapted to the shape of the blowing agent.
  • the number of propellants is symmetrically distributed over the two propellant zones, each propellant zone offering space for at least one propellant.
  • At least one component of the drive machine is arranged to the left or right of the two drive zones.
  • the benefit of this arrangement is that the size of the prime mover is reduced.
  • the distance between the two propellant zones can be reduced accordingly in order, for example, to arrange the propellants as close as possible to the left and right of the guide rails. This minimizes the space required by the drive machine and the entire drive arrangement.
  • the small dimensions of the drive machine allow a compact design.
  • the compact design also allows an optimal introduction of the support forces into the supporting structure, which in turn enables simpler forms of the substructure.
  • the assembly handling and the alignment of the drive machine is greatly improved by the compact design and the possible pre-assembly of the individual assemblies in an assembly-friendly environment.
  • a prime mover 20 has as in FIGS. 1 a to 1e and FIGS. 2 to 4 shown a drive shaft 4, which with two at a distance D from each other spaced driving zones 3, 3 'is provided.
  • a motor 1 and a brake 2 act on the drive shaft 4.
  • the drive zones 3, 3 'drive propellants 19, 19' which, as exemplified in FIG Figures 5 to 8 shown driving a car 11 and a counterweight 12.
  • the distance D is advantageously chosen to be as small as possible. It results, for example, from the intended arrangement of the driving zones or the propellants 19, 19 'on both sides of the car guide rail 5.
  • the motor 1 and / or the brake 2 and / or other components such as speed sensors, evacuation aids or optical indicators are on the left and right according to the invention / or to the right of the two driving zones 3, 3 '.
  • the best combination can be determined using the possible arrangements for the components of the drive machine 20.
  • the benefit of this arrangement results from the fact that the space requirement for the drive machine 20 can be minimized in accordance with the requirements of the system arrangement.
  • the drive machine 20 is designed with a small overall length. This enables extensive pre-assembly of the drive machine in a suitable working environment. This simplifies assembly and eliminates sources of error.
  • Fig. La shows the arrangement of the motor 1 and a first bearing 28 on one side of the drive zones 3, 3 'and the brake 2 and a second bearing 28' on the other side of the drive zones 3, 3 '.
  • Consoles 29, 29 ' are attached to the support structure of the elevator system in accordance with the arrangement of the bearings 28, 28'.
  • This variant is advantageously used when the distance D between the drive zones 3, 3 'is selected to be small, which is useful, for example, with very small guide rail dimensions.
  • FIG. 1b shows the use of a central bracket 22 which guides the bearing forces of the drive machine 20 centrally, essentially at one point, into the supporting structure of the elevator installation.
  • the central console 22 is arranged at right angles to the axis of the drive machine 20, acting in a plane of symmetry S of the two drive zones 3, 3 '. This enables a particularly cost-effective design of the connecting structure.
  • this arrangement enables the use of a level adjustment 27.
  • the level adjustment 27 only has to take on small differential forces, which result essentially from the weight forces of the drive itself and from inaccuracies in the propellant arrangement.
  • the level adjustment 27 enables the axis of the drive shaft 4 to be aligned without any particular effort the direction of travel of the propellants 19, 19 '.
  • This alignment is particularly advantageous when using belts as the propellant, since it has a decisive influence on the wear and noise behavior. If the drive machine is inaccurately aligned, the propellant wear increases significantly, which leads to an early replacement of the propellant and, accordingly, to high costs.
  • This is exemplary Figure 1b the brake 2 and the motor 1 are arranged on one side of the drive zones 3, 3 '. This arrangement is advantageous if the space on the opposite side of the driving zones is otherwise occupied.
  • Figure 1c shows the arrangement of a central bearing 21 which absorbs the radial force of the drive shaft 4 generated by the tensile forces present in the propellant 19, 19 'at a central point.
  • the central bearing 21 is arranged at right angles to the axis of the drive machine, acting in a plane of symmetry S of the two drive zones 3, 3 '.
  • a support bearing 24 is arranged at the end of the drive shaft 4 on the motor side. It takes over the differential forces arising in the drive system. The differential forces result essentially from the weight forces of the drive itself and from inaccuracies in the propellant arrangements.
  • the support bearing 24 also ensures that the air gap between the stator and the rotor of the motor 1 is precisely maintained.
  • the drive machine 20 is fastened to the supporting structure of the elevator system by means of two consoles 29, 29 '.
  • This arrangement is particularly advantageous if the distance D between the drive zones 3, 3 'leaves enough space for the arrangement of the central bearing 21 and the requirements for the alignment accuracy of the drive shaft are low.
  • Fig. 1d shows the arrangement of a central warehouse 21 and a central bracket 22 which guides the bearing forces of the drive machine 20 centrally, essentially at one point, into the supporting structure of the elevator installation.
  • the central console 22 and the central bearing 12 are arranged at right angles to the axis of the drive machine 20, acting in a plane of symmetry S of the two drive zones 3, 3 '.

  • Fig. 1e shows another possible arrangement of a level adjustment 27.
  • the level adjustment 27 is arranged in this embodiment directly on the bearing housing. Its effect is identical to that below Figure 1b , 1d embodiment shown. Those skilled in the art can define further embodiments as they are best suited for a specific application.
  • FIGS. 1 a to 1e can be combined in a suitable form by the person skilled in the art.
  • the brake 2 can be arranged, for example, between the drive zones 3, 3 ′.
  • FIGS. 2 and 3 show an exemplary detailed version of the in Fig 1d illustrated arrangement.
  • the drive machine 20 shown has a drive shaft 4 with two spaced apart drive zones 3, 3 ′.
  • the distance D between the two driving zones is 100 to 250 mm.
  • the drive shaft 4 is mounted in a bearing housing 7.
  • a central console 22 is integrated into the bearing housing 7.
  • the central bracket 22 is arranged in a plane of symmetry S between the two drive zones 3, 3 'at right angles to the drive axis and in a plane of symmetry S defined by the two drive zones.
  • the drive shaft 4 is supported in the bearing housing 7 by means of a central bearing 21 arranged between the drive zones 3, 3 '.
  • the central warehouse 21 is also arranged to act in the plane of symmetry S.
  • the central bearing 21 absorbs the bearing forces originating from the propellants 19, 19 'and guides them via the bearing housing 7, the central console 22 and via an intermediate piece into the supporting structure of the elevator installation.
  • the drive zones 3, 3 ′ are incorporated directly into the drive shaft 4.
  • the drive zones 3, 3 ′ can also be applied to the drive shaft 4 by means of separate elements, such as, for example, in the form of disks.
  • the drive shaft 4, or the drive zones 3, 3 ' is force-effectively connected to a motor 1 and a brake 2, preferably in one piece and without a gear, and thus enables the drive means 19, 19' to be driven by the drive zones 3, 3 '.
  • the driving zones 3, 3 ' are also in one piece in the embodiment shown Drive shaft 4 integrated. This is advantageous when using belts as propellants, since these propellants enable small deflections or driving radii.
  • By arranging the central bearing 21 between the driving zones 3, 3 ' the space available there is used efficiently and the external dimensions are reduced. By reducing the number of storage locations, costs are reduced.
  • the quality of the drive machine 20 is significantly increased by this arrangement, since the reduction of the bearing points eliminates the need for overdetermination of the shaft bearings.
  • the brake 2 and the motor 1 are advantageously arranged to the left and right of the two drive zones 3, 3 ′, as shown in the examples.
  • the motor 1 and the brake 2 are connected in a force-effective manner via the bearing housing 7.
  • the drive torques generated by the motor 1 and / or the braking torques generated by the brake 2 are introduced into the bearing housing 7 and via the central console 22 into the supporting structure of the elevator system.
  • the illustrated arrangement of the drive zones 3, 3 'between the brake 2 and the motor 1, together with the force-effective connection of the brake 2, the motor 1 and the bearing housing 7, enables a particularly space-saving design.
  • the accessibility to the brake 2 and the motor 1 is ideally guaranteed.
  • a support bearing 24 is arranged at the end of the drive shaft 4 on the motor side.
  • the support bearing 24 takes over the differential forces arising in the drive system.
  • the differential forces result essentially from the weight forces of the drive itself and from inaccuracies in the propellant arrangements.
  • the support bearing 24 also ensures exact compliance with the air gap between the stator and the rotor of the motor 1.
  • the support bearing 24 conducted the differential forces into the housing of the motor and the bearing housing 7.
  • the resulting support forces are absorbed by a level setting 27 and into the supporting structure of the Elevator system initiated.
  • the level adjustment 27 serves at the same time for the precise and simple leveling of the axis of the drive shaft 4 in relation to the propellants 19, 19 '. This alignment is particularly advantageous when using belts as a propellant, since it significantly influences the wear and noise behavior.
  • the level setting 27 can be arranged horizontally, for example.
  • the bearing housing 7 shown partially encloses the drive shaft 4 with the drive zones 3, 3 ′. This forms a direct protection of the propellant zones 3, 3 'from unintentional contact and the risk of trapping by assembly or service personnel, but also prevents damage to the propellant zone or the propellant from falling objects. At the same time, the bearing housing gains the necessary strength to take over the forces and moments from the motor 1 and the brake 2.
  • the drive machine 20 is fastened by means of vibration isolations 23, 26. This enables a large degree of vibration decoupling of the drive machine 20 from the supporting structure of the elevator installation. This reduces the noise in the elevator system and / or in the building.
