Abstract
The utility model relates to a kind of low-power fan rotor elastic vibration clamper using sliding bearing.Comprise upper limit cover, stage clip and lower limit and overlap three parts, it is characterized in that upper limit is set in the top of lower limit cover, upper and lower stop collar cooperatively interacts, and stage clip is located between upper and lower stop collar, and lower limit cover is fixed on rotor.Described upper limit cover both sides to be provided with in draw-in groove that Elastic buckle is stuck in lower limit cover and to be fixed on bearing face.Described lower limit cover both sides are provided with draw-in groove, and centre is provided with spring setting sleeve location stage clip.Described stage clip is located in the middle of the next cover.When rotor uses elastic vibration clamper rear fan can use under environment at any angle, fan rotor can be stabilized in a certain position or play buffer function to the play of rotor under the effect of elastic member, reduce the noise that blower fan causes because of play, the online production yield rate of blower fan is significantly promoted.
Description
Technical field
The utility model relates to a kind of low-power fan rotor elastic vibration clamper using sliding bearing, belongs to field of machining and machinebuilding technology.
Background technique
At present, the low-power fan of domestic and international use sliding bearing generally adopts the structure in axially little play gap, because blower fan is at the active force of the process rotor operated by coil magnetic field, during blower fan work simultaneously, leaf oar is subject to the effect of shear flow and translation air-flow, fan rotor is made to bear larger axial force, and rotor is under the dynamic balancing active force of self, make rotor in operation process, form the randomness of axial displacement, the irregular shock of rotor stop collar and bearing face is caused to form noise, especially the occasion angularly installed and used of motor shaft and level is particularly evident, this has a strong impact on the working life of blower fan.
Model utility content
The utility model is for above-mentioned the deficiencies in the prior art, design a kind of low-power fan rotor elastic vibration clamper, the free play of the axis of fan rotor is become under elastic acting force condition, has resistance play, to reduce the wearing and tearing of impact noise and rotor and bearing face, improve the working life of blower fan.
The utility model relates to a kind of low-power fan rotor elastic vibration clamper using sliding bearing.Comprise upper limit cover, stage clip and lower limit and overlap three parts, it is characterized in that upper limit is set in the top of lower limit cover, upper and lower stop collar cooperatively interacts, and stage clip is located between upper and lower stop collar, and lower limit cover is fixed on rotor.Described upper limit cover both sides to be provided with in draw-in groove that Elastic buckle is stuck in lower limit cover and to be fixed on bearing face.Described lower limit cover both sides are provided with draw-in groove, and centre is provided with spring setting sleeve location stage clip.Described stage clip is located in the middle of the next cover.
The Elastic buckle of described upper limit cover can be symmetrical arranged on both sides, also can circumferentially annular spread arrange.
The draw-in groove of described lower limit cover can be symmetrical arranged on both sides, also can circumferentially annular spread arrange.
Described stage clip decompressor can be general spring device, also can be other elastic-like vibration damping equipments.
The beneficial effects of the utility model are: after adopting rotor elastic vibration clamper, blower fan can use under environment at any angle, fan rotor can be stabilized in a certain position or play buffer function to the play of rotor under the effect of elastic member, reduce the noise that blower fan causes because of play, the online production yield rate of blower fan is significantly promoted, solves blower fan conforming problem under various angle installation conditions.
Working procedure of the present utility model is as follows: when blower fan is subject to the active force of coil magnetic field at the process rotor of running, blower fan leaf oar is subject to the effect of shear flow and translation air-flow simultaneously, fan rotor is made to bear axial force, and rotor is under the dynamic balancing active force of self, rotor will drive the lower limit cover axial motion be arranged on from it, and this axial displacement becomes and has resistance play under the effect of damping pressure spring, fan rotor can be stabilized in a certain position or play buffer function to the play of rotor under the effect of elastic member, this reduces the randomness that rotor forms axial displacement in operation process greatly, also reduce simultaneously rotor clash into form noise, especially the occasion noise reduction angularly installed and used of motor shaft and level is particularly evident.

Embodiment
Embodiment 1:
With reference to Fig. 1, it is a kind of low-power fan rotor elastic vibration clamper.Comprise upper limit cover 1, stage clip 2 and lower limit cover 3 three parts, it is characterized in that upper limit cover 1 is located at the top of lower limit cover 3, upper and lower stop collar cooperatively interacts, and stage clip 2 is located between upper and lower stop collar, and lower limit cover 3 is fixed on rotor.Described upper limit overlap 1 both sides be provided with Elastic buckle be stuck in lower limit cover 3 draw-in groove in and be fixed on bearing face.Described lower limit is overlapped 3 both sides and is provided with draw-in groove, and centre is provided with spring setting sleeve location stage clip 2.Described stage clip 2 is located in the middle of the next cover 3.
Embodiment 2:
The difference of this example and embodiment 1 be Elastic buckle that described upper limit overlaps circumferentially annular spread arrange.
Embodiment 3:
The difference of this example and embodiment 1 be draw-in groove that described lower limit overlaps circumferentially annular spread arrange.
Embodiment 4:
With the difference of embodiment 1, this example is that described stage clip vibration damping equipment is other elastic-like vibration damping equipments.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
