Abstract
The utility model discloses a dust collector motor, including motor section and fan part, the fan part is main takes turns and decides the impeller including the movable vane, motor section mainly includes the motor, and the motor has the output shaft, move install impeller on the output shaft of motor, the part of installation movable vane wheel is the segment of a circle on the output shaft of motor, the mounting hole of movable vane wheel also is the complex segment of a circle. The utility model discloses design the archwise with the part of installation movable vane wheel on the motor output shaft to the mounting hole that makes the movable vane wheel also is the complex segment of a circle, therefore both can constitute flat position cooperation structure when combining, has avoided when the motor is high -speed to operate the movable vane wheel to take place the condition of skidding, the performance of maintaining dust collector motor that can be fine.
Description
Technical field
The utility model relates to a kind of motor of dust collector, belongs to machine field.
Background technology
At present, dust catcher has come into huge numbers of families as a kind of household cleaning apparatus.Existing dust catcher can be divided into vertical, horizontal and portable by structure.The operation principle of dust catcher is: utilize motor of dust collector to produce air negative pressure, draws dirt bits.
Existing motor of dust collector is formed primarily of two parts: motor part and fan section.Because motor of dust collector is very high to rotation speed requirements, generally at 20000 ~ 30000 rpms, therefore motor mainly adopts is series excitation class motor, is also called series machine.Fan section mainly comprises two critical pieces: movable vane is taken turns and determined impeller; Wherein, movable vane wheel mainly produces wind, and when movable vane wheel rotates with the high rotating speed of 20000 ~ 30000 rpms, air inlet can produce negative pressure shape and become vacuum, and then forms suction; Determine impeller, be also called inducer, Main Function makes movable vane take turns more smooth-going the discharging of air quantity produced; Determine the quality in impeller air channel, will directly affect the efficiency of motor of dust collector.In prior art, movable vane wheel is installed on the output shaft of motor, and before and after movable vane wheel, both sides arrange packing ring, then are locked on output shaft with nut.
But, practical application finds, because output shaft is cylindrical, structure that what itself and movable vane were taken turns be locked is very infirm, the situation that movable vane wheel skids can be there is in motor when running up, especially, after using a period of time, the situation that impeller skids is particularly evident, has had a strong impact on the performance of motor of dust collector.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of motor of dust collector.
To achieve the above object of the invention, the technical solution adopted in the utility model is: a kind of motor of dust collector, comprises motor part and fan section, and described fan section mainly comprises movable vane wheel and determines impeller; Described motor part mainly comprises motor, and motor has output shaft; Described movable vane wheel is installed on the output shaft of motor; The output shaft of described motor is installed the part of movable vane wheel arcuately, the installing hole of described movable vane wheel is also arc in what coordinate.
Above, the output shaft of described motor is installed movable vane wheel part arcuately, and the installing hole that movable vane take turns also in coordinate arc, therefore both in conjunction with time, can form flat position fit structure, when can motor be avoided well to run up there is the situation of skidding in movable vane wheel.
Above-mentioned this structure is that flat structure is done in the side of output shaft, certainly, also all can do flat structure in the both sides of output shaft.This belongs to simple replacement.
Preferably, on the output shaft of described motor, arc area is greater than the area of the semicircle of its correspondence.
In technique scheme, the both sides, front and back of described movable vane wheel are provided with packing ring, and are tightly fixed on described output shaft by nut lock.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1. the utility model motor output shaft will be installed the partial design archwise of movable vane wheel, and the installing hole making movable vane take turns is also arc in what coordinate, therefore both in conjunction with time, flat position fit structure can be formed, avoid movable vane wheel when motor runs up and the situation of skidding occurs, the performance of motor of dust collector can well be maintained;
2. structure of the present utility model is simple, is easy to realize, and is suitable for applying.
Accompanying drawing explanation
Fig. 1 is the exploded perspective figure of the utility model embodiment one.
Wherein: 1, movable vane wheel; 2, output shaft; 3, installing hole; 4, packing ring; 5, nut.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment one
