Definitions

  • the invention relates to a transmission turbo compressor comprising a transmission housing, at least one turbomachine having a turbomachine shaft extending along an axis, the at least one turbomachine comprising a volute, comprising at least one impeller rotatably formed about the axis, comprising at least one turbomachinery shaft portion of the turbomachine shaft the impeller is mounted, an inflow comprises for the admission of a process fluid into the volute, an outflow comprises to the outlet of the process fluid from the volute.
  • the invention relates to a method for aligning a spiral housing relative to a transmission housing for such a geared turbomachine.
  • turbomachinery with turbomachinery shafts - often called pinion shafts - around a drive shaft - which is also often called wheel shaft - are regularly arranged on a transmission housing or gearbox.
  • An increasing number of turbomachines provided on the gear compressor - often compressors - or an increasing size of the individual compressors arranged there leads to the problem of arranging the compressors on the two opposite sides, at which the shaft ends of the turbomachine shafts are led out, of the gearbox and at the same time to obtain thermodynamically meaningful speeds at the individual turbomachines as a result of a large wheel diameter and pinion diameters in the transmission.
  • a particular advantage of the invention is that the adjustment or alignment device is not space-defining.

  • the gear housing has a parting line which forms a common surface with the first contact surface of the housing alignment part.
  • the spiral housing is bolted axially in a ready-to-use state with the transmission housing.
  • the term axial here refers to the longitudinal axis of the screw and the direction of extension of the turbomachine shaft, so that the screws for screwing and the shaft axis extend in identical directions along.
  • the spiral housing is first brought into an approximate approximate to the final operating position position relative to the gear housing and is secured at this point in the game of screwing initially by means of screws against falling, without the volute casing with a final Tighten torque to the gearbox housing.

  • a particularly preferred embodiment provides that the spiral housing bolted to the bearing plate of the transmission housing is.
  • the transmission housing, the bearing, the shaft seal and the volute casing together form a solid unit that virtually eliminates deformation-related play bridging between stationary and rotating components. Further advantages of this modularity are shown in a lower vibration output as a result of the direct connection of the force-carrying components with each other even under dynamic load.
