Definitions
- the present invention relates to the technical field of fan wheels or ventilation wheels or centrifugal compression wheels, intended to equip devices of the fan or centrifugal compressor type.
- the present invention relates to a centrifugal compression wheel comprising a metal hub intended to be connected to a drive shaft and on which are fixed an inlet flange and an outlet flange between which are fixed ventilation vanes, as well as its manufacturing process.
- Centrifugal compression wheels intended to equip various fans or compressors are widely known and generally consist of a series of blades arranged around an axis of rotation and connected together by parts of revolution which may have the form of 'a disc, a cone, or a ring or which can be of any toroidal shape.
- the object of the invention therefore aims to remedy the various drawbacks listed above and to propose a new centrifugal compression wheel made of composite material and having improved resistance to deformation.
- Another object of the invention is to propose a new centrifugal compression wheel having improved resistance to angular deformation around an axis perpendicular to the axis of rotation.
- Another object of the invention is to propose a new centrifugal compression wheel of simplified design.
- Another object of the invention is to propose a new centrifugal compression wheel whose assembly and assembly are particularly simplified.
- Another object of the invention is to propose a new centrifugal compression wheel having good resistance to external aggressions.
- An object of the invention also aims to propose a new method of manufacturing a composite centrifugal compression wheel which is particularly simple to implement and to produce.
- centrifugal compression wheels comprising a metal hub intended to be connected to a drive shaft, and on which are fixed an inlet flange and an outlet flange between which blades are fixed, characterized in that they comprise an annular metallic insert which is integrated in the central part of the wheel at the periphery of the hub, and which comprises metallic elements forming the start of the blades of the wheel, the flange inlet and outlet flange as well as the remaining and peripheral part of the blades being made of composite material to constitute the composite part of the wheel.
- a centrifugal compression wheel comprising a metal hub on which are fixed an inlet flange and an outlet flange between which are fixed blades, characterized in that it comprises the following stages:
- a metal insert is produced which comprises metal elements forming the start of the blades of the wheel;
- FIG. 1 illustrates, in a perspective view, an embodiment of a centrifugal compression wheel according to the invention.
- FIG. 2 illustrates, in a partial cross-sectional view, a first alternative embodiment according to the invention.
- FIG. 3 illustrates, in a partial cross-sectional view, another alternative embodiment of the invention.
- FIG. 4 illustrates, in a partial cross-sectional view, an additional alternative embodiment of the invention.
- FIG. 5 illustrates, in a transverse view of a compression wheel according to the invention, a detail of embodiment of a compression wheel having parallel flanges.
- 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 (in general of the air) to transport and transit.
- a series of vanes 7 is interposed between the inlet flanges 4 and the outlet 5, forming a spacer.
- the blades 7 are most often inclined and sometimes purely radial, depending on the specifics and the field of application of the centrifugal compression wheel 1.
- the inlet flanges 4 and outlet 5 can 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 can 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 an outlet flange 5 plane ( Figures 2 to 4).
- the two flanges 4, 5 can both be also 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 metallic elements 7A forming the start of the blades of the wheel, the inlet flange 4 and the outlet flange 5 as well as the remaining and peripheral part 7B of the blades being made of composite material to constitute the composite part of said wheel.
- the metal elements 7A thus form the leading edge of the blades 7, which then consist of two sections extending one inside the other to constitute a complete blade, namely an internal section formed by metal elements 7A and a peripheral section of composite material 7B. Thanks to this specific assembly, the deformations at the level of the composite wheel are greatly reduced, which increases the general robustness of the wheel, in particular for wheels rotating at high peripheral speed, while benefiting from the good resistance of the metallic material which composes the leading edge of the vanes 7. It is in fact mainly at the leading edges of the blades that the aggression of solid or liquid particles conveyed by the aspirated fluid is maximum.
- the metal insert 8 is mounted between the two flanges 4, 5 so as to be able 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 attached to the latter by any known means, and 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 from one another. Between these latter 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 made integral with the flanges 4, 5 by means of a fixing means, and for example by a set of bolts 10 ensuring on one side the support and the 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.
- a fixing means and for example by a set of bolts 10 ensuring on one side the support and the 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.
- the hub 2 can advantageously include in its external peripheral part an annular flat 11, for positioning radially in consideration of the axis of the drive shaft 3, the outlet flange 5. As illustrated in FIG. 4, the annular flat 11 is formed on the internal face of the hub 2 facing the inlet flange 4.
- the metal insert 8 is an integral part of the hub 2 so as to form only one single piece with the latter.
- the hub 2 comprises, towards its peripheral upper part, an annular flat 11 formed on the external face of the hub so as to form a projection on which the outlet flange 5 rests.
- the front flange 4 is supported by the front part and annular 12 of the hub 2, which advantageously comprises, as illustrated in FIG. 2, a circular neck 13 on which rests, peripherally, the inlet flange 4.
- the assembly is carried out by a set of bolts 10, or by any other equivalent means well known to those skilled in the art.
- the composite wheel according to the invention may include a metallic annular reinforcement 15 mounted against the external face of one of the flanges, in this case in this case, against the inlet flange 4.
- the metallic annular reinforcement 15 is assembled with the metallic insert 8, in the present case, with the annular part 12 of the hub 2, through the flange 4 to support the composite part.
- the metallic annular reinforcement 15 is mounted on and against the outside of the inlet flange 4, it being understood that as a variant, and for further strengthening the robustness of the assembly, a second metallic annular reinforcement 15 could be mounted against the outlet flange 5.
- the metal insert 8 can be produced using techniques well known to those skilled in the art, and for example by machining or molding, or can be composed of separate parts and assembled by welding.
- the composite part of the compression wheel according to the invention can be produced either by molding of composite materials, or by conventional methods involving the assembly of various components or composite elements connected by successive stages of a mechanical process or a process involving a series of bonding steps.
- the material constituting the composite part of the wheel is determined according to the manufacturing method used.
- the method of manufacturing a centrifugal compression wheel comprising a metal hub on which is fixed an inlet flange and an outlet flange between which blades are fixed is characterized in that it involves the following steps:
- a metal insert is produced which comprises metal elements forming the start of the blades of the wheel;
- a composite part of the impeller formed by the inlet flange, the outlet flange and the remaining and peripheral portion of the blades is assembled directly on said insert, by a suitable method.
- the assembly that is to say the joining or junction between the metal insert and the composite part, can be carried out mechanically using any conventional fixing means, the composite part therefore being produced separately during 'a previous step.
- step b) of assembly is carried out at the same time as the manufacturing operation of the composite part, by directly molding the composite part of the wheel on the metal insert.
- the molding operation is carried out by overmolding of one (or more) composite material.
- the metal insert thus constitutes a support for the centrifugal forces applied to the wheel capable of reducing the deformations.
- the compression wheel will be perfectly symmetrical, which facilitates its manufacture, reduces the cost of tooling, and also has an advantage in deformation reduction material.
- the integration of a metal structure in the inlet and suction area of the composite wheel constitutes excellent protection of the composite parts of the wheel against deteriorating agents such as solid or liquid particles carried by the sucked fluid. .
- the invention finds its industrial application in the design and manufacture of centrifugal fans or compressors.
