  • the device according to the invention is formed by a centrifugal compression wheel 1 comprising a metal hub 2 intended to be connected, by any known means, to a drive shaft 3.
  • the centrifugal compression wheel 1 is formed by two flanges, for example circular 4, 5, provided with a central opening, and respectively defining an inlet flange 4 and an outlet flange 5 of the fluid flow (generally from the air) to convey and to transit.
  • a series of blades 7 is interposed between the inlet flanges 4 and outlet 5, forming a spacer.
  • the vanes 7 are arranged most often inclined and sometimes purely radial, this depending on the specificities and the field of application of the centrifugal compression wheel 1.
  • the inlet and outlet flanges 4 and 5 may be planar, or of conical shape or any other surface of revolution around the axis of the wheel, as illustrated in FIGS. 2 to 5, and may be associated in pairs. indifferently to form a pair of parallel flanges ( Figure 5) or to form a pair of flanges associating a conical inlet flange 4 with a plane outlet flange ( Figures 2 to 4).
  • the two flanges 4, 5 can both be conical without departing from the scope of the invention.
  • the centrifugal compression wheel 1 comprises an annular metal insert 8 which is integrated in the central part of the compression wheel 1 at the periphery of the hub 2 and in the vicinity of the central opening of the flanges 4, 5, and which comprises metal elements 7A forming the start of the vanes of the wheel, the inlet flange 4 and the outlet flange 5 as well as the remaining and peripheral portion 7B of the vanes being made of composite material for constituting the composite part of said wheel.
  • the metal elements 7A thus form the leading edge of the blades 7, which are then constituted by two sections extending one inside the other to form a complete blade, namely an internal section formed by metal elements 7A and a peripheral section made of composite material 7B.
  • the metal insert 8 is mounted between the two flanges 4, 5 so as to support the composite part over its entire transverse width.
  • the metal insert 8 is formed by an annular piece independent of the hub 2 and reported on the latter by any known means, for example by welding or bolting.
  • the metal insert 8 is formed by two annular bodies 8A, 8B having the form of flanges and concentric with the hub 2, these two annular bodies 8A, 8B being spaced apart from each other. Between these are arranged and interposed at regular intervals the metal elements 7A forming the metal primers of the blades 7.
  • Each annular body 8A, 8B is secured to the flanges 4, 5 by means of a fixing means, and for example by a set of bolts 10 providing on one side the support and support between the hub 2 and the outlet flange 5, and on the other side the connection between the annular body 8A and the inlet flange 4. As shown in FIG.
  • the hub 2 may advantageously comprise in its outer peripheral part an annular flat surface 11, for positioning radially in consideration of the axis of the drive shaft 3, the outlet flange 5.
  • the annular flat portion 11 is formed on the inner face of the hub 2 facing the inlet flange 4.
  • the metal insert 8 is an integral part of the hub 2 to form a single piece with the latter.
