Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of quiet motor used for range hood, comprise described rotor, stator and the motor housing for fixed stator, described rotor is installed on described motor housing by rotating shaft, rotate around described rotating shaft, described stator is fixed in described motor housing.Described rotor comprises internal rotor, external rotor, rotating shaft 3, described rotating shaft 3 runs through and arranges internal rotor center, and be connected with described internal rotor fixed drive, described internal rotor, external rotor arrange interlaced fan annular flange flange 7 respectively, damping, buffering material 5 is provided with, the fan loop configuration that described flange 7 is is the center of circle with rotating shaft 3 between described flange 7.Described flange 7 annular is uniformly distributed.The fan loop configuration that described flange 7 is is the center of circle with rotating shaft 3.The radius in the described center of circle is crossed in the side of fan loop configuration, in the course of work internal rotor, external rotor to the extruding force of damping, buffering material 5 perpendicular to side, therefore internal rotor, external rotor and damping, buffering material 5 can not produce the relative sliding in laterally direction, damping, buffering material 5 can not produce wearing and tearing in the course of the work, and its performance is very stable.
Described internal rotor, the external rotor flange 7 that magnitude setting is equal respectively, the quantity of flange 7 is 2 to 6, and the quantity that flange 7 is arranged can not be very little.Easily cause internal rotor, external rotor eccentric iff arranging one, when running up, vibration is more serious, arrange too many, be limited within circumference, short of width, single flange 7 insufficient strength, gap between flange 7 is too little, damping, buffering material 5 thickness is not enough, affects damping effect, when motor high-power start easily damages rotor.The present embodiment internal rotor, external rotor preferentially arrange 3 fan annular flange flange 7, and the central angle corresponding to described fan loop configuration is 40 °.
Damping, buffering material 5 is divided into 6 deciles to be arranged in the gap of flange 7 both sides.No matter motor rotates forward or reversion or no matter motor accelerates or deceleration, and described flange 7 both sides all arrange onesize damping, buffering material 5, avoids damping, buffering material 5 uneven distribution and the bias that causes.No matter be internal rotor in addition, external rotor produce vibration or the vibration produced with motor coupling portion part, damping, buffering material 5 all effectively can weaken the vibration of transmitting this 3 positions.
Be provided with gap between described internal rotor flange 7 and external rotor, between described external rotor flange 7 and described internal rotor, be provided with gap.Described gap is set to 0.05mm ~ 1mm.The present embodiment intermediate gap is set to 0.1mm.
Described internal rotor, external rotor are made up of silicon steel sheet in multi-disc 2, outer silicon steel sheet 1 respectively, described interior silicon steel sheet 2 is linked into an integrated entity by rivet 4, described outer silicon steel sheet 1 is integrally fixed by cast aluminium 6, described cast aluminium 6 reduces the gap with stator, form magnetic field, closed-loop path, described interior silicon steel sheet 2 is the circulus being equipped with fan annular flange flange 7 outward, is equipped with the circulus of fan annular flange flange 7 in described outer silicon steel sheet 1.
Gap between flange 7 outer ring surface of described outer silicon steel 1 and described interior silicon steel sheet 2 is 0.05 ~ 1mm, and between flange 7 outer ring surface of described interior silicon steel 2 and described outer silicon steel sheet, the gap of 1 is 0.05 ~ 1mm.The outer silicon steel sheet 1 of prioritizing selection is 0.1mm with the gap of described interior silicon steel sheet 2, and flange 7 outer ring surface and described interior silicon steel sheet 2 gap of the outer silicon steel sheet 1 of prioritizing selection are 0.1mm, flange 7 outer ring surface of interior silicon steel sheet 2 and the gap of outer silicon steel sheet 1 are 0.1mm.
Gap can ensure that rotor is when accelerated service or intermittent working, exist when internal rotor, external rotor rotate around rotating shaft 3 and relatively rotate, energy when padded coaming deformation buffer relatively rotates, reach damping object, when being out of shape with limit damping, buffering material 5, external rotor departs from the axle center of rotating shaft 3, deviation position is limited within the specific limits, reduces eccentric vibrating, ensure that rotor magnetic line affects by gap minimum simultaneously.
Interrupted or that running produces the continuously vibrational energy of motor passes to internal rotor by rotating shaft 3, extruding damping, buffering material 5, damping, buffering material 5 is as buffer strip abatement vibrational energy, vibrational energy after abatement passes to external rotor again, also outwards propagate to motor and range hood air stomach, housing simultaneously, reach the effect that damping is quiet.Power between inner and outer rotors is transmitted by the flange 7 of fan annular, the fan loop configuration that described flange 7 is is the center of circle with rotating shaft 3, during rotation, only there is the extruding force in perpendicular contact face in flange 7 and damping, buffering material 5, slip between flange 7 and damping, buffering material 5 is very small, and friction is each other trickle, and the damping performance of damping, buffering material 5 fails because of wearing and tearing hardly, structure of the present utility model is simple, and damping performance is stablized.
The above; be only the utility model preferably embodiment; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claim.
