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 claims.
  • An object of the present invention is to provide a prime mover and a method for assembling the same, which optimizes the power flow and thus minimizes the requirements on the adjacent construction and minimizes the space required for the prime mover.
  • the prime mover should also allow a flexible arrangement in the shaft.
  • the carrier and propellant strand is to be divided into two strands.
  • the invention relates to a drive machine for an elevator system with cabin and counterweight and a shaft.
  • Carrying and blowing agents connect the cabin to the counterweight.
  • the carrying and blowing agents are called blowing agents in the following.
  • the propellants are passed over the drive machine.
  • the propellants are driven in the prime mover by a drive shaft.
  • the zones of the drive shaft which transmit the force to the propellant are referred to below as the propellant zones.
  • the car and the counterweight are guided by means of car guide rails or counterweight guide rails.
  • the drive shaft has two spaced apart blowing zones.
  • the blowing zones are adapted to the shape of the blowing agent.
  • the number of propellants is distributed symmetrically over the two propellant zones, with each propellant zone providing space for at least one propellant.
  • At least one component of the drive machine is arranged on the left or right of the two drive zones.
  • the benefit of this arrangement is that the dimensions of the prime mover are reduced.
  • the distance between the two blowing zones can be reduced as appropriate by, for example, to arrange the propellant in the smallest possible distance left and right of the guide rails.
  • the small dimensions of the drive machine allow a compact design.
  • the compact design allows further optimal introduction of the bearing forces in the support structure which in turn allows simpler forms of the substructures.
  • the assembly handling and the alignment of the drive machine is greatly improved by the compact design, and therefore possible pre-assembly of the individual assemblies in a mounting-friendly environment.
  • a drive machine 20 has a drive shaft 4, which is connected to one another by two at a distance D. spaced blowing zones 3, 3 'is provided. A motor 1 and a brake 2 act on the drive shaft 4.
  • the drive zones 3, 3 'drive propellant 19, 19' which as shown by way of example in FIGS. 5 to 8 drive a car 11 and a counterweight 12.
  • the distance D is advantageously chosen as small as possible. It results, for example, from the intended arrangement of the blowing zones or the blowing means 19, 19 'on both sides of the car guide rail 5.
  • the engine 1 and / or the brake 2 and / or other components such as speed sensors, evacuation aids or visual indicators are according to the invention left and / or right of the two blowing zones 3, 3 'arranged.
