Below in conjunction with Fig. 1-Fig. 4, the electric machine assembly 100 of the dryer of embodiment according to a first aspect of the present invention is carried out in detail
Thin description.
As depicted in figs. 1 and 2, electric machine assembly 100 according to embodiments of the present invention may include that motor 1, impeller 2 and stops
Block piece 3, wherein, one end of the output shaft 11 of motor 1 can be provided with fitted shaft 12, and one end of the neighbouring motor 1 of fitted shaft 12 can
To be provided with the most outwardly axial stop 121, the outer peripheral face of fitted shaft 12 could be formed with the first plane
120, to realize and the coordinating of impeller 2.
As it is shown in figure 1, can be provided with on impeller 2 axially through installing hole 21, the inner peripheral surface of installing hole 21 can be formed
Having the second plane (not shown) coordinated with the first plane 120, fitted shaft 12 can be located in installing hole 21, and join
The free end of sympodium 12 can be with protruding installing hole 21.Thus, the first plane 120 in fitted shaft 12 can with in installing hole 21
The second plane coordinate, when fitted shaft 12 rotates, the first plane 120 and the second plane contact, such that it is able to impeller 2 turns
Dynamic, it is achieved main story or reversion.
As depicted in figs. 1 and 2, stop part 3 is detachably arranged in the free end of fitted shaft 12, and impeller 2 can only only be against
Between block piece 3 and axial stop 121.
Thus, it is possible to impeller 2 is carried out axial limiting by stop part 3 and axial stop 121, simple and compact for structure.
Further, during electric machine assembly 100 forward or reverse, impeller 2 is passed with the realization that coordinates of the second plane by the first plane 120
Dynamic, will not get loose, safety is good, and reliability is high.Meanwhile, when needing repairing or change impeller 2, by stop part 3 from fitted shaft 12
Free end pull down, it is possible to being pulled down by impeller 2, easy accessibility, maintenance cost is cheap.
Electric machine assembly 100 according to embodiments of the present invention, by forming the first plane on the outer peripheral face of fitted shaft 12
120, and form the second plane on the inner peripheral surface of the installing hole 21 of impeller 2, utilize the first plane 120 and cooperation of the second plane
Realizing transmission, by stop part 3 being detachably arranged in the free end of fitted shaft 12, utilizing stop part 3 and axial stop 121
Realizing the axial location to impeller 2, such that it is able to realize rotating, and it is loosening not result in impeller 2 during rotating,
There is the advantages such as simple in construction, safety is good, easy accessibility, maintenance cost are cheap.
In some embodiments of the invention, the cross section of fitted shaft 12 can be formed as semicircle, and installing hole 21 is permissible
Being formed as semi-circular hole, thus, the outer peripheral face of fitted shaft 12 can be made up of an arcwall face and a plane, and this plane is
Above-mentioned first plane 120, similarly, the inner peripheral surface of installing hole 21 can be made up of an arcwall face and a plane, this plane
It is above-mentioned second plane.When fitted shaft 12 is plugged in installing hole 21, arcwall face can coordinate with arcwall face, and plane is permissible
Coordinating with plane, conformability is good, and can pass through Planar realization transmission, simple in construction, convenient processing.
In other embodiments of the present invention, as shown in figs 2-4, the cross section of fitted shaft 12 can be formed as more than half
Circle, thus it is possible not only to realize transmission, and the intensity of fitted shaft 12 can be improved, improve reliability.
In the still other embodiments of the present invention, the cross section of fitted shaft 12 can be formed as polygon, and installing hole 21 can
To be formed as polygonal hole, thus after fitted shaft 12 is located in installing hole 21, can limit fitted shaft 12 and installing hole 21 it
Between relatively rotate, it is achieved transmission.Further, no matter motor 1 main story or invert, all without affecting fitted shaft 12 and installing hole 21
Matching relationship, do not result in impeller 2 and loosen, safety is good, and stability is high.
Certainly, the shape of the cross section of the fitted shaft 12 of the present invention is not limited to this, if shape on the outer peripheral face of fitted shaft 12
Become the first plane 120, realize transmission by the first plane 120 with coordinating of the second plane, it is possible to avoid motor 1 forward
Or the phenomenon that when reversely switching rotates, impeller 2 gets loose.Shape description above for the cross section of fitted shaft 12 is example
The description of property, it is impossible to be interpreted as limitation of the present invention.
According to some embodiments of the present invention, output shaft 11 may be integrally formed with fitted shaft 12, say, that output shaft
11 and fitted shaft 12 can be one-body molded part, such that it is able to simplify process for machining and manufacturing further, reduce cost.
As Figure 1-Figure 4, the outer peripheral face of free end can be provided with external screw thread 122, stop part 3 can be stop nut,
After fitted shaft 12 is located in installing hole 21, is provided with the free end of external screw thread 122 and can stretch out installing hole 21, stop nut with from
With external screw thread 122 on end, it is possible to achieve the axial location to impeller 2, simple and compact for structure, and not by 1 turn of motor
To impact, reliability of positioning is high.
Alternatively, the radial dimension of output shaft 11 can be more than the maximum radial dimension of fitted shaft 12, the court of output shaft 11
End face to one end of fitted shaft 12 can be formed as axial stop 121, say, that axial stop 121 can be by exporting
The shaft shoulder of axle 11 is formed.Thus, simple in construction, the convenient disassembly when maintenance, can reduce processing and maintenance cost further.
In order to improve the reliability of the axially location to impeller 2 further, electric machine assembly 100 can also include: air ring
Sheet (not shown), annular gasket can be located on output shaft 11, and annular gasket can only be against axial stop 121
And between impeller 2, annular gasket can provide assosting effect to the axially location of impeller 2, improves the reliability of location.Meanwhile,
Annular gasket can also provide certain protection to axial stop 121 and impeller 2, it is to avoid axial stop 121 is direct with impeller 2
Contact, reduces collision and abrasion.
According to some embodiments of the present invention, the minimum range between the first plane 120 and the rotation axis of output shaft 11
The minimum range between outer peripheral face and the rotation axis of free end of free end can be more than, such that it is able to during avoiding assembling
The installation of fitted shaft 12 and installing hole 21 is produced by free end to be interfered, and reduces installation difficulty further, improves installation effectiveness.
