Brushless direct current motor is run with autocontrol, so will not turn as the synchronous motor of heavy load starting under frequency control
Another plus startup winding, will not also produce vibration and step-out in load changing on son, therefore, be applied in portable dust collector field
Extensively.The internal rotor dust catcher brushless electric machine of prior art, the structure design that generally use bearing axial distance fixes are this to set
Other accessory size uniformity are must assure that during meter motor assembling, because each accessory size has certain margin of tolerance, are finally made
Motor assembly qualified rate substantially reduces.In addition, there is the phenomenon of axle play in the also presence of diastema.
Utility model content
(1) technical problems to be solved
The purpose of this utility model seeks to overcome disadvantages mentioned above, it is desirable to provide a kind of brushless dust catcher inner rotor motor
Rotor component construction.
(2) technical scheme
To reach above-mentioned purpose, the rotor component construction of brushless dust catcher inner rotor motor of the present utility model, including it is outer
Shell, rotor assembly, fan housing, determine impeller and movable vane wheel, wherein, between rotor assembly is arranged on shell and determines impeller, fan housing is located at
Above movable vane wheel, movable vane wheel includes rotor core, drive shaft, fore bearing, rear bearing positioned at impeller top, the rotor assembly is determined
And spring；The rotor core is fixedly connected with drive shaft；
The fore bearing is placed on above drive shaft, and the rear bearing holder (housing, cover) is below drive shaft；
The fore bearing and drive shaft close-fitting, the rear bearing are matched somebody with somebody with drive shaft pine；
The spring is inserted in drive shaft, and is installed between rotor core and rear bearing.
Further, the fore bearing is provided with clutch shaft bearing nesting.
Further, the rear bearing is provided with second bearing nesting.
Further, the bottom on the inside of the shell, which is provided with, just accommodates the groove with the nested rear bearing of second bearing.
Further, described to determine impeller and be provided with some fixing holes, the shell is provided with the fixation coordinated with the fixing hole
End.
(3) beneficial effect
Compared with prior art, the technical solution of the utility model has advantages below：It is of the present utility model after bearing with
Drive shaft pine is matched somebody with somebody and adds a spring, fore bearing and drive shaft between bearing and rotor core afterwards and determine impeller close-fitting, such axle
Axial distance is held because can freely change when spring force shrinks or upholds, when so assembling complete machine, axle when being not in assembling
Stuck or axial pine has axle play diastema to tight motor, because of movable vane wheel and rotor one, and diastema presence can make on movable vane wheel
Lower play interference fan housing determines impeller.
Brief description of the drawings
Fig. 1 is the explosive view of the rotor component construction of brushless dust catcher inner rotor motor of the present utility model；
Fig. 2 is the utility model rotor assembly explosive view；
Fig. 3 is the structural representation after the assembling of the utility model rotor assembly.
Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not limited to the scope of the utility model.
As shown in Figure 1 to Figure 3, the rotor component construction of brushless dust catcher inner rotor motor of the present utility model, including it is outer
Shell 1, rotor assembly 2, fan housing 3, determine impeller 4 and movable vane wheel 5, wherein, between rotor assembly 2 is arranged on shell 1 and determines impeller 4,
Fan housing 3 is located at the top of movable vane wheel 5, and movable vane wheel 5 includes rotor core 6, drive shaft positioned at the top of impeller 4, the rotor assembly 2 is determined
7th, fore bearing 8, rear bearing 9 and spring 10；The rotor core 6 is fixedly connected with drive shaft 7；
The fore bearing 8 is placed on the top of drive shaft 7, and the rear bearing 9 is placed on the lower section of drive shaft 7；
The fore bearing 8 and the close-fitting of drive shaft 7, the rear bearing 9 are matched somebody with somebody with the pine of drive shaft 7；
The spring 10 is inserted in drive shaft 7, and is installed between rotor core 6 and rear bearing 9.
The fore bearing 8 is provided with clutch shaft bearing nesting 11.
Bearing 9 is provided with second bearing nesting 12 after described.
The bottom of the inner side of shell 1 is provided with the groove 15 for just accommodating the rear bearing 9 with second bearing nesting 12.
Under the elastic reaction of spring 10, bearing axial distance can freely change because of the contraction of the elastic force of spring 10 or when upholding.
Described to determine impeller 4 and be provided with some fixing holes 13, the shell 1 is provided with the fixing end coordinated with the fixing hole 13
