Abstract
An impeller for a fan having a hub that can be easily fastened to a shaft is disclosed. A multiplicity of vanes is fastened to the hub. At least one elastic damping body is provided in the hub between the receptacle and the vanes to damp the transfer of vibrations from the shaft to the vanes, and prevent vibration of the vanes relative to each other. A slotted central sleeve in the inner section of the hub forms the receptacle for the shaft and is surrounded by an annular spring.
Description
- The present invention relates to an impeller for a fan, e.g. for a room fan or a built-in fan for cooling and/or air circulation in an electrical appliance.
- Particularly in the case of small-format high-speed fans, vibrations of a drive motor, being transferred to the impeller of a fan, can provoke a resonant frequency of the impeller. This results in considerable operating noise of the fan, in addition to which the vibration can lead to material fatigue of the impeller and to its destruction in the course of time.
- The object of the present invention is to specify an impeller for a fan, which impeller is insensitive to possible vibrations of a drive motor.
- In the case of a fan impeller having a hub in which a receptacle for a driving shaft is formed, and having a plurality of vanes which are fastened to the hub, the object is achieved by means of the hub having at least one elastic damping body that is arranged between the receptacle and the vanes.
- In order to damp the transfer of vibrations from the shaft to the vanes, and as far as possible to prevent vibrations of the vanes relative to each other, the vanes are preferably fastened to a hub outer ring which is connected via the damping body to a hub inner section having the receptacle.
- According to a first specific embodiment, the damping body can occupy an annular intermediate space between the outer ring and the inner section.
- Alternatively, it is also possible to arrange a plurality of damping bodies, these being circumferentially distributed, in an annular intermediate space between the outer ring and the inner section.
- The damping body preferably consists of a different material than the outer ring and/or the inner section, in particular of a material having high elasticity. In particular, this material can be a silicone or a rubber.
- However, an embodiment is also conceivable in which the plurality of circumferentially distributed damping bodies are embodied integrally with the outer ring and the inner section. In this case, the required elasticity of the damping bodies can be achieved by means of said damping bodies having a smaller wall thickness than the outer ring or the inner section.
- If the damping bodies are not embodied in one piece with the ring or the inner section, it is advantageous for the ring and/or the inner section to have recesses into which the damping bodies engage positively, such that ring and inner section cannot be rotated in opposite directions.
- In order to ensure that the damping bodies are held firmly, the recesses can be undercut.
- The inner section preferably comprises a central sleeve, which forms the receptacle, and an annular wall that runs annularly around the sleeve at a distance. An annular spring surrounding the slotted sleeve can therefore be introduced for the purpose of fastening the impeller to a shaft.
- The central sleeve and the annular wall can be connected in one piece in order to simplify manufacture.
- A connecting piece which connects the central sleeve to the annular wall is preferably arranged at an end face of the hub. An axially extending intermediate space can therefore be created between the central sleeve and the annular wall, wherein said space can comfortably accommodate an axially extending spring which acts to fasten the hub to the shaft.
- According to an alternative embodiment, an annular spring can also surround the inner section, and the at least one damping body is arranged in an annular intermediate space between the outer ring and the inner section so as to be axially offset relative to the spring.
- The impeller is preferably used in a fan which is arranged in a domestic appliance such as a refrigerator. It is thereby possible to prevent an unpleasant noise level when the fan is operating, particularly during a rest phase of the compressor.
- Further features and advantages of the invention emerge from the following description of exemplary embodiments with reference to the appended figures, in which:
-
FIG. 1 shows a perspective sectional view of an impeller according to the present invention; -
FIG. 2 shows a radial section through the hub of an impeller according to a second embodiment of the invention; -
FIG. 3 shows a section, similar to that inFIG. 2 , according to a third embodiment; -
FIG. 4 shows a section, similar to that inFIG. 2 , according to a fourth embodiment; -
FIG. 5 shows a perspective sectional illustration of an impeller according to a fifth embodiment. - The impeller shown in
FIG. 1 has ahub 1 of essentially cylindrical form, from whose outer circumference a plurality ofvanes 2 project. The number ofvanes 2 is largely arbitrary, the example illustrated here comprising fourvanes 2, of which only two are visible in the figure. Thesevanes 2 are integrally connected to anouter ring 3 of thehub 1. A plurality ofsilicone damping bodies 6 are arranged circumferentially at equal intervals in anannular cavity 4 between theouter ring 3 and aninner section 5 of thehub 1, saidinner section 5 being arranged within saidouter ring 3. Of the four damping bodies here, three can be seen in the figure, of which two in cross section. Thedamping bodies 6 are the only frictional connection between theouter ring 3 and theinner section 5. - The
inner section 5 comprises an outerannular wall 7 and, surrounded by this and concentric relative thereto, asleeve 8 which is open in the direction of an end face of thehub 1, said end face facing away from the observer, in order to accommodate a shaft (not shown) of a drive motor. Aslot 9, which is open towards the end face facing towards the observer, extends transversely through thesleeve 8. Theannular wall 7 and thesleeve 8 are connected in one piece at the end face facing away from the observer by a radially orientedwall 10. Thewall 10, theannular wall 7 and thesleeve 8 respectively form the base and two side walls of anannular groove 11, which is open in the direction of the end face of theinner section 3, said end face facing towards the observer, in order to accommodate a slottedannular tension spring 12. As a result of the two halves of thesleeve 8 being pressed together by thetension spring 12, a secure press fit is achieved in respect of the impeller on the drive shaft that is accommodated in thesleeve 8. - Any transfer of unevennesses (in the shaft movement) to the
outer ring 3 or thevanes 2 is damped by means of thedamping bodies 6. Because thedamping bodies 6 damp any movement of theannular wall 7 and theinner section 5 relative to each other, they also suppress the development of sympathetic vibration of thevanes 2. - Depending on elasticity and damping ability of the
damping bodies 6, it can be effective to increase their number or their circumferential extent until the extreme case as shown inFIG. 2 (in cross section along the line II indicated inFIG. 1 ) is reached, in which thecavity 4 is completely occupied by a singleannular damping body 6. - In the embodiments shown in
FIGS. 1 and 2 , the friction between thedamping bodies 6 and theouter ring 3 or theinner section 5 essentially prevents any lasting rotation of thering 3 relative to theinner section 5. For this purpose, it is necessary for the dampingbody 6 to be elastically deformed at all times, in order to establish the required pressure against thering 3 and theinner section 5. This can prove problematic, particularly if the fan is exposed to low temperatures (e.g. when used for circulating cold air in a domestic refrigerator), since many of the rubber-elastic materials that are suitable for thedamping bodies 6 have an elasticity that decreases significantly at low temperatures. Different thermal expansion coefficients of the selected materials can also contribute to the marked temperature dependency of the friction between thedamping bodies 6 and thering 3 and/or theinner section 5. - In order to achieve a damped elastic while nonetheless rotation-resistant coupling between the
outer ring 3 and theinner section 5, irrespective of the temperature, a further developed embodiment makes provision for recesses into which the dampingbodies 6 engage on the opposing surfaces of theinner section 5 and thering 3. Particularly secure fixing of the damping bodies is achieved if, as illustrated in a section inFIG. 3 which is similar to that inFIG. 2 , the recesses on theouter ring 3 and theinner section 5, designated 13 and 14 respectively, are undercut and thedamping bodies 6, having an H-shaped cross section here, engage positively in the undercuts of therecesses damping bodies 6 is required in the balanced state, and therefore thedamping bodies 6 can yield slightly to a torque acting between thering 3 and theinner section 5. The more yielding thedamping bodies 6, the lower the resonance frequency of any rotational shearing of thering 3 and theinner section 5 relative to each other. By selecting this resonance frequency such that it is sufficiently remote from any frequency component of the motor movement, rotational shearing of thering 3 relative to theinner section 5 can be effectively prevented or damped to a level that is not relevant in terms of noise development. - A simplified modification is illustrated in
FIG. 4 . In this case, thedamping bodies 6 that are made of silicone and fixed to the walls of thering 3 and/or theinner section 5 are replaced bynarrow bridges 15, which are molded integrally with thering 3 and theinner section 5 and whose elasticity is derived from their considerably thinner wall thickness in comparison with theouter ring 3 and theinner section 5. - A further simplified embodiment is illustrated in
FIG. 5 in a view which is similar to that ofFIG. 1 . In this embodiment, theannular wall 7 of the embodiments considered above is omitted and theslotted sleeve 8 is connected in one piece to the outer ring 3 (which carries the vanes 2) via aradial wall 16 at the end face of thehub 1, said end face facing towards the motor of the shaft. The thickness of thewall 16 is clearly less than that of thewall 10 in the previously considered embodiments; it allows a vibration of theouter ring 3 relative to thesleeve 8 along an axis which runs transverse to the rotational axis of thehub 1. At the same time, any such vibration is significantly damped by anannular damping body 17 which is pressed into anannular groove 18 between thesleeve 8 and thering 3. - As explained with reference to
FIG. 1 , atension spring 12 is axially pushed onto thesleeve 8 in order to clamp a shaft that is accommodated in thesleeve 8. It is also possible to omit thetension spring 12 and to apply the pressure to thesleeve 8 by means of the pressed-in dampingbody 17 alone, said pressure being required for the purpose of clamping the shaft.
