Abstract
The invention relates to an impeller damping mechanism which is used for solving a problem that the vibration during the use of an existing air blower is large. The impeller damping mechanism comprises a bottom plate (1) connected with a rotary shaft (4) of a motor, and blades (2) which are distributed on the bottom plate (1) in a ring-shaped manner, wherein the bottom plate (1) is tightly fitted with the rotary shaft (4) of the motor; the bottom plates (1) at the two ends of each blade (2) are integrally connected. According to the impeller damping mechanism, the bottom plate (1), the motor rotary shaft (4) and the blade (2) are integrally connected, so that the vibration of each part when the impeller rotates is effectively avoided, and good mute effect can be realized.
Description
Technical field
The present invention relates to impeller damper mechanism.
Background technique
The blade that existing blower impeller is arranged in the rotating shaft of motor by multiple one end mostly forms, the free end of blade produces air quantity along with the rotation of rotating shaft, but this impeller only has one end to fix due to blade, easily when high speed rotating, the root that can be connected with rotating shaft at impeller forms larger turbulent flow, therefore, under the effect of centrifugal force and turbulent gas, cause vane rotary blade to produce vibrations.
Chinese patent specification CN 203201877 U discloses the reinforcement shock-damping structure of the quiet impeller of a kind of blower, comprise the base plate be connected with the rotating shaft of motor, and annular spread is at the blade at backplate surface edge, vaned outside be provided with the reinforcement outer ring be jointly connected with all blades, vaned structural strength can be improved, but owing to having gap between central shaft and center hole, easily cause central shaft rock in center hole and cause impeller to shake when blade rotation.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of stability of rotation, shockproof blower damping blade wheel structure.
A kind of impeller damper mechanism of the present invention, a kind of impeller damper mechanism, comprises the base plate 1 be connected with the rotating shaft 4 of motor, and the blade 2 of annular spread on base plate 1.Rotating shaft 4 drive fit of described base plate 1 motor, described blade 2 two ends base plate 1 is connected.After adopting this structure, motor shaft directly drives blade rotation, and blade two ends are fixed on base plate 1, like this can effectively vane rotary time the rocking of each parts, effectively realize damping.
As a modification of the present invention, the radial direction of described blade 2 slightly becomes S type, and axially slightly toward outer incline, two ends are passed through welding and formed one with base plate 1, and like this, this blade 2 effectively can collect air and form air-flow, and control air-flow blows out from impeller central.
Improve as another kind of the present invention, the center hole 3 be provided with by described base plate 1 and the drive fit of motor shaft 4, described base plate 1, motor shaft 4, blade 2 are connected, and this spline structure is simple, and rocking when avoiding vane rotary between base plate 1 and motor shaft 4.Further, described blade 2 is 6 ~ 8, can produce enough large air quantity like this, effectively can save material again.And blade 2, base plate 1 are plastic materials, plastics are flexible and cost-saving.
In sum, a kind of impeller damper mechanism of the present invention can produce stable air-flow, has the damping achieving blower quiet, effectively extends the working life of blower.
Accompanying drawing explanation
Fig. 1 is the plan structure schematic diagram of a kind of impeller damper mechanism of the present invention.
In figure: 1 base plate, 2 blades, 3 center holes, 4 motor shafts.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As shown in Figure 1, a kind of impeller damper mechanism of the present invention, comprises the base plate 1 be connected with the rotating shaft 4 of motor, and the blade 2 of annular spread on base plate 1, and described blade 2, base plate 1 are plastic materials.Base plate 1 is provided with center hole 3, and described motor shaft 4 is linked together by drive fit mode and base plate 1.Described base plate 1 is provided with 6 ~ 8 blades 2.The radial direction of described blade 2 slightly becomes S type, axially slightly toward outer incline, two ends form one by welding and base plate 1, like this, after opening blower power, motor shaft rotates impeller and rotates, and described base plate 1, motor shaft 4, blade 2 are connected, rocking between efficiently avoid between each parts, thus achieve the damping of blower and quiet.
