Description
Technical field
The utility model relates to axial flow blower technical fields, more particularly, to a kind of vibrationproof driving motor of axial flow blower.
Background technique
Axial flow blower includes driving motor and fan blade, and driving motor generally comprises shell, is placed in the intracorporal stator of shell and turns
Son, and output shaft that is affixed with rotor and stretching out the shell, the shell includes the main casing for fixed stator, and is set to
The main casing both ends and the drive end bearing bracket and rear end cap for passing through output shaft described in bearing support.Fan blade is connected with exporting axis, and is driving
It is rotated under the driving of dynamic motor, gas is made to be parallel to fan shaft flowing.Fan blade is generated the trend of axial movement by airflow function,
And there is axial fit-up gap between output shaft and the drive end bearing bracket and rear end cap of driving motor, therefore fan blade rotates Shi Huifa
The raw vibration along output shaft axial direction, the vibration is first is that bring noise, second is that blower is caused to be difficult to stablize, it is easy to damage.Eliminate motor
Axial gap is to overcome one of effective means of vibration, generallys use the following two kinds mode: 1, by drive end bearing bracket bearing flat shim
It holds out against；2, front cover adds screw device to lock bearing.But both modes have the defects that top power is excessive, all can be in various degree
Bearing is damaged, motor can shake loose device for a long time, gap is caused to increase.
Utility model content
The purpose of the utility model is to overcome above-mentioned technical deficiencies, propose a kind of vibrationproof driving motor of axial flow blower,
When solving that axial flow blower works in the prior art, the technical issues of driving motor output shaft easy radial vibration.
To reach above-mentioned technical purpose, the technical solution of the utility model provides a kind of vibrationproof driving electricity of axial flow blower
Machine, including shell are placed in the intracorporal stator of shell and rotor, and output shaft that is affixed with rotor and stretching out the shell, the shell
Body includes the main casing for fixed stator, and passes through output shaft described in bearing support set on the main casing both ends and respectively
Two end cap, wherein the end cap includes the mounting groove for accommodating the bearing, which is also a housing for vibrationproof component, described
Vibrationproof component include be sheathed on the output shaft and two sides abut respectively it is described installation groove bottom and bearing wave washer, and
The anaerobic adhesive being filled in the mounting groove.
Compared with prior art, the beneficial effects of the utility model include: the elastic force using wave washer automatically by gap
Reduce, while using anaerobic adhesive isolation air just cured characteristic, anaerobic adhesive slowly solidifies after assembly, make axial clearance of motor into
One step is eliminated, and elastic force is moderate not to hurt bearing, and electrical machinery life is long.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model vibrationproof driving motor；
Fig. 2 is enlarged drawing at A in Fig. 1.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
As shown in Figure 1, the utility model provides a kind of vibrationproof driving motor of axial flow blower, including shell 1, it is placed in shell
Intracorporal stator 2 and rotor 3, and output shaft 4 that is affixed with rotor 3 and stretching out the shell 1, the shell 1 include for solid
The main casing 11 of stator 2, and the both ends of the output shaft 4 are supported by bearing 13 set on 11 both ends of main casing and respectively
Lid 12, wherein the end cap 12 includes the mounting groove 121 for accommodating the bearing 13, which is also a housing for vibrationproof group
Part 5, as shown in Fig. 2, the vibrationproof component 5 includes being sheathed on the output shaft 4 and two sides abut the mounting groove 121 respectively
The wave washer 51 of bottom surface and bearing 13, and the anaerobic adhesive 52 being filled in the mounting groove 121.The vibrationproof component 5 can be with
It is only set at one in end cap 12, can also all be arranged in two end caps 12.
When this programme is implemented, the wave washer 51 of suitable elastic force is first selected according to 13 model of bearing, into mounting groove 121 and
13 outer wall of bearing coats anaerobic adhesive 52, and wave washer 51 and bearing 13 are put into mounting groove 121, and anaerobic adhesive 52 is in air at this time
It will not solidify at once in environment.End cap 12 is combined with main casing 11, and suitably pressure pushes against, and utilizes the elastic force of wave washer 51
Automatically axial clearance of motor is reduced, and with the combination of end cap 12 and main casing 11, mounting groove 121 is interior to form closed loop
Border has completely cut off air, and anaerobic adhesive 52 slowly solidifies at this time, eliminates axial clearance of motor further.
To keep the state of the bearing 13 more stable, more specific scheme is proposed, the output shaft 4 has for abutting two
The stage portion 41 of the bearing 13, to balance the elastic force from wave washer 51 that any bearing 13 is subject to.Further, described
Output shaft 4 includes the different deferent segment of at least two sections of diameters, and junction forms the stage portion 41.When the vibrationproof component 5
When being only set at one in end cap 12, the output shaft 4 includes the different deferent segment of two sections of diameters, and junction forms the step
Portion 41；When the vibrationproof component 5 is all arranged in two end caps 12, the output shaft 4 includes the different deferent segment of three sections of diameters,
Its junction forms the stage portion 41 at two, abuts two bearings 13 respectively.
Specific embodiment of the present utility model described above does not constitute the restriction to scope of protection of the utility model.
Any other various changes and modifications that any technical concept according to the present utility model is made should be included in practical
In novel scope of protection of the claims.
