Definitions

  • the invention relates to turbo radial fans with a motor housing and a rotating unit mounted in this housing, consisting of a shaft, a fan rotor and a motor armature, a first roller bearing between the fan rotor and motor armature and a second roller bearing in the region of the end of the shaft facing away from the fan rotor are provided and the roller bearings in the housing are assigned elastically supported bearing supports, the outer bearing ring of the second roller bearing being supported in the sleeve-shaped bearing support via an elastic support in the axial direction.
  • a blower of this type is known from EP-A 235 392.
  • the assembly and disassembly of such a blower is obviously difficult, so that the replacement of wearing parts is complex and requires long interruptions in operating time.
  • the balancing process can only be carried out after the rotating unit has been installed in the housing.
  • the elastic mounting of the bearings in the housing make it difficult to identify the position of unbalances.
  • this object is achieved in that the rotating unit consisting of the blower rotor, shaft and motor armature can be assembled and disassembled together with the bearing supports and the elastic support in the form of a coil spring as a whole in the motor housing and in that the outer diameter of the support of the first bearing is larger than the outer diameter of the motor armature and support of the second bearing and that the diameter of the support of the second bearing is equal to or preferably less than the diameter of the motor armature.
  • the rotating unit can be removed as a whole from the fan housing in a fully functional form after the flow housing has been detached. The replacement of wearing parts that may be necessary during maintenance and repair work is particularly easy.
  • the entire rotating unit can be replaced, for example. It is advantageous that the rotating unit can be balanced independently of the motor housing, and that much more precisely. When installed, elastic bearing suspensions are absolutely necessary, which complicate the balancing process. The balancing process of a removed rotating unit can be carried out without elastic bearing suspension.
  • Another advantage of the invention is that the bearing brackets - in particular the disk-shaped bearing brackets associated with the first bearing - allow more precise guidance of the bearings in the motor housing due to their relatively large diameter.
  • the figure shows a turbo radial blower 1 with a flow housing 2 and a motor housing 3.
  • the flow housing comprises the gas inlet 4, the wall 6 delimiting the flow channel 5, the diffuser 7 and the collecting channel 8 with the outlets 9.
  • the rotating unit held in the motor housing 3 consists from the fan rotor 11, the shaft 12 and the motor armature 13.
  • Rolling bearings 14 and 15 are provided for mounting the shaft 12, one of which (14) is arranged between the fan rotor 11 and the motor armature 13, while the second bearing 15 is located in the region of the free end of the shaft 12 facing away from the fan rotor 11.
  • Bearing supports 16 and 17 are provided for holding the roller bearings 14 and 15 in the bearing housing 3.
  • the bearing bracket 16 associated with the rolling bearing 14 has the shape of a disk with a relatively large diameter. It is elastically supported in the housing 3 via the O-ring 18.
  • the bearing support 17 assigned to the rolling bearing 15 has the shape of a sleeve which is supported elastically in the bearing housing 3 via the O-rings 21 and 22.
  • the outer bearing ring of the rolling bearing 15 is supported by a helical spring 23, so that thermal longitudinal expansions of the shaft 12 are possible.
  • the motor and storage space of the motor housing 3 is closed on the side of the fan rotor with a flange-like cover 24 which is screwed to the motor housing 3 by means of screw connections 25 arranged on the side of the fan rotor 11.
  • the motor housing itself is equipped with a flange 26, which in turn is detachably connected to the flow housing 2 via screw connections 27 that are accessible from the outside.
  • the outer diameter of the disk-shaped bearing bracket 16 is larger than the diameter of the motor armature 13, and its diameter is in turn larger than the outer diameter of the sleeve-shaped bearing bracket 17. Because of these dimensions, it is possible after the separation of the flow housing 2 and motor housing 3 and after Removing the cover 24 and taking the rotating unit (blower rotor 11, shaft 12, motor armature 13) out of the motor housing 3 as a whole. This makes it particularly easy to replace the rotating unit. It is essential that the rotating unit can be completely balanced outside of the bearing housing 3. It is not necessary to make the rotating unit resilient in the balancing machine. When installed, this elastic suspension is absolutely necessary so that completely vibration-free storage is possible.
