It is placed on the rotor assembly, the bearing is set on the axis and is installed in the bearing chamber of the end cap, the powder
Die casting sector axle sleeve, bowl-type gasket, movable vane wheel and gasket are sequentially arranged on the axis, and the fan housing is by press-fit solid
It is scheduled on the end cap outer circle, the outer circle of the bowl-type gasket is stretched vertically face, and fluted, the groove is arranged in the end cap face
Ordinatedly it is set to the stretched vertically of the bowl-type gasket.
Preferably, the periphery of the powder die-casting sector axle sleeve is provided with sector.
Preferably, the axis is provided at both ends with screw thread and is locked by nut.
Preferably, the material of the end cap is BMC materials.
The positive effect of the utility model is：
The utility model is provided with groove using bowl-type gasket with end cap, avoids water and impurity via Wet-dry dust catcher
Air inlet be inhaled into inside motor fan, and centrifugal force of the blade of powder die-casting sector axle sleeve when running at high speed will be into
The subtle water and impurity entered is thrown away, and has effectively prevented Wet-dry motor of dust collector because water and impurity enter bearing and bearing caused to lose
Effect even results in burn-down of electrical machinery, the water resistance for effectively improving Wet-dry motor of dust collector is realized, even if in severe work
Condition is capable of the service life of effective guarantee and extension Wet-dry motor of dust collector, and powder die-casting sector axle sleeve is powder pressure
Casting, significantly reduces motor cost.

Specific implementation mode
The utility model is further illustrated below by the mode of embodiment, but is not therefore limited in the utility model
Among the embodiment described range.
As shown in Fig. 1~5, a kind of novel waterproof structure for motor of the utility model, including rotor assembly 1, axis 2, bearing
3, end cap 4, powder die-casting sector axle sleeve 5, bowl-type gasket 6, movable vane wheel 7, gasket 8 and fan housing 10, axis 2 are set to rotor assembly 1
On, bearing 3 is set on axis 2 and is installed in the bearing chamber of end cap 4, powder die-casting sector axle sleeve 5, bowl-type gasket 6, movable vane wheel
7 and gasket 8 be sequentially arranged on axis 2, fan housing 10 by press-fit is fixed on 4 outer circle of end cap, and the outer circle of bowl-type gasket 6 is
