Definitions
- the present invention relates to an impeller for a fan, such as a room fan or a built-in fan for cooling and / or recirculating air in an electrical device.
- Object of the present invention is to provide an impeller for a fan that is insensitive to possible vibrations of a drive motor.
- the hub has at least one arranged between the receptacle and the wings elastic damping body in a fan impeller with a hub, in which a receptacle for a driving shaft is formed, and a plurality of attached to the hub ,
- the wings are preferably attached to an outer ring of the hub, which with a receptacle having inner portion of the hub on the Damping body is connected.
- the damping body can fill an annular space between the outer ring and the inner portion.
- a plurality of damping bodies may be distributed in an annular space between the outer ring and the inner portion distributed in the circumferential direction.
- the damping body is made of a different material than the outer ring and / or the inner portion, in particular of a material with higher elasticity.
- This material may in particular be a silicone or a rubber.
- the plurality of circumferentially distributed damping body are made integral with the outer ring and the inner portion.
- the required elasticity of the damping body can be achieved by having a smaller wall thickness than the outer ring or the inner portion.
- the damping bodies are not formed integrally with the ring or the inner portion, it is expedient that the ring and / or the inner portion have recesses into which the damping body engage positively, so that the ring and inner portion are not rotated against each other.
- the recesses may be undercut.
- the inner portion preferably comprises a central sleeve forming the receptacle and an annular wall extending at a distance around the sleeve.
- an annular spring can be clamped around the slotted sleeve.
- the central sleeve and the annular wall can be integrally connected for ease of manufacture.
- a connecting piece which connects the central sleeve and the annular wall is preferably arranged on an end face of the hub.
- an annular spring can also clasp the inner portion, and the at least one damping body is arranged in an annular space between the outer ring and the inner portion axially offset from the spring.
- the impeller is used in a fan arranged in a household appliance, such as a refrigerator.
- a household appliance such as a refrigerator. This avoids an unpleasant noise level during fan operation, in particular during a standstill phase of the compressor of a refrigeration device.
- Fig. 1 is a perspective sectional view of an impeller according to the present invention
- Figure 2 is a radial section through the hub of an impeller according to a second embodiment of the invention.
- Fig. 3 is an analogous to Fig. 2 section according to a third
- Fig. 4 is an analogous to Fig. 2 section according to a fourth
- Fig. 5 is a perspective sectional view of an impeller according to a fifth embodiment.
- the impeller shown in Fig. 1 has a hub 1 of substantially cylindrical shape, projecting from the outer periphery a plurality of wings 2.
- the number of wings 2 is largely arbitrary, in the example shown here there are four wings 2, of which only two are visible in the figure. These wings 2 are integrally connected to an outer ring 3 of the hub 1.
- a plurality of damping body 6 made of silicone in the circumferential direction are arranged evenly spaced. Of the total of four damping bodies are three in the figure to see, two in section.
- the damping body 6 represent the only non-positive connection between the outer ring 3 and the inner portion 5.
- the inner portion 5 comprises an outer annular wall 7 and, surrounded by this and concentric with it, a sleeve 8, which faces away from the viewer end face of the
- Hub 1 is open to receive a (not shown) shaft of a drive motor. Transverse through the sleeve 8 extends to the viewer facing
- the wall 10 Viewer facing away from the end face by a radially oriented wall 10 integrally connected.
- the wall 10, the annular wall 7 and the sleeve 8 each form the bottom or two side walls of an annular groove 11, which faces the viewer facing end of the
- Inner section 3 is open to receive a slotted annular tension spring 12.
- tension spring 12 presses the two halves of the sleeve 8 against each other, it ensures a firm clamping fit of the impeller on the received in the sleeve 8 drive shaft.
- recesses are provided according to a further developed embodiment on the opposite surfaces of the inner portion 5 and the ring 3, in which the damping body. 6 intervention.
- a particularly firm anchoring of the damping body is achieved if, as shown in Fig. 3 in a section analogous to FIG. 2, the recesses on the outer ring 3 and the inner portion 5, designated 13 and 14, are undercut and the damping body. 6 , here of H-shaped cross-section, positively engage in the undercuts of the recesses 13, 14.
- FIG. 4 A simplified modification is shown in Fig. 4.
- the anchored to the walls of the ring 3 and the inner portion 5 damping body 6 are replaced silicone by narrow webs 15, which are integrally molded with the ring 3 and the inner portion 5 and whose elasticity results from their compared to the outer ring 3 and the inner portion 5 substantially smaller wall thickness.
- FIG. 5 A further simplified embodiment is shown in FIG. 5 in a view analogous to FIG. 1.
- the annular wall 7 of the previously considered embodiments omitted, and the slotted sleeve 8 is connected to the wing 2 bearing outer ring 3 in one piece via a radial wall 16 on the motor of the shaft facing end face of the hub 1.
- the thickness of the wall 16 is significantly less than that of the wall 10 in the previously considered embodiments, it allows a vibration of the outer ring 3 with respect to the sleeve 8 about an axis extending transversely to the axis of rotation of the hub 1 axis.
- such a vibration is strongly damped by an annular damping body 17, which is pressed into an annular groove 18 between the sleeve 8 and the ring 3.
- a tension spring 12 is axially slid onto the sleeve 8 on the sleeve 8 in order to clamp a shaft accommodated in the sleeve 8. It is also possible to omit the tension spring 12 and to exert the pressure required for clamping the shaft on the sleeve 8 only with the aid of the pressed damping body 17.
