Definitions

  • a blower of this type is known from EU-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.
  • 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.
