Abstract
The utility model provides the mounting structure of a kind of motor and impeller, including motor, impeller, motor includes rotor case, the middle part of impeller is provided with a cavity with opening, the cavity bottom is provided with positioning column, the shell of the motor rotor is provided with the location hole matched with positioning column, the opening of the wheel cavity is provided with grab, the shell of the motor rotor is mounted in wheel cavity, wherein, in the location hole of the positioning column insertion motor of impeller, the impeller grab is caught in the end face of motor rotor shell.The utility model structure only needs simply to fasten the assembly that impeller and motor can be realized, and mounting means is simple, while the installation of motor and impeller occupies little space, and the assembly of motor and impeller is detachable, easy to maintenance.
Description
Technical field
The utility model relates to the mounting structures of a kind of motor and impeller.
Background technique
Currently, there are mainly two types of the motor of industry mainstream and impeller mounting means.One is impellers to pass through motor drive shaft, passes through
Nut, which is tightened, is allowed to impeller fixation on the motor, reaches the structural principle of motor running impeller work, such installation side
Formula is complex, and equipment component is limited by space, is not available the installation of this structure.Another kind is press-fit structure, impeller
Press-assembling surface diameter is slightly less than motor case diameter, and by external force by impeller press-assembling to motor case, interference fit is realized axial
With radial fixation.Such mounting means needs motor case stress, and motor case needs to guarantee certain intensity, increases horse
Up to containment weight, while when being pressed impeller, impact force is easy to damage motor case or bearing.
Utility model content
In view of the above technical problems, the utility model provides the mounting structure of a kind of motor and impeller, including motor, leaf
Wheel, motor include rotor case, and the middle part of impeller is provided with a cavity with opening, the wheel cavity bottom setting
There is positioning column, the shell of the motor rotor is provided with the location hole matched with impeller positioning column, and the wheel cavity is opened
It is provided with grab at mouthful, the motor rotor shell is mounted in wheel cavity, wherein the positioning column insertion motor of impeller is determined
In the hole of position, the impeller grab is caught in the end face of motor rotor shell.
Further, the impeller positioning column is arranged to wedge.
Further, prominent muscle is provided on the inner sidewall of the wheel cavity.
The utility model has the beneficial effects that
The utility model structure only needs simply to fasten the installation that impeller and motor can be realized, and mounting means is simple,
The assembly of motor and impeller occupies little space simultaneously, and prominent muscle can reinforce motor and impeller assembly intensity, guarantees the firm of installation
Property, the assembly of motor and impeller is detachable, easy to maintenance.
Detailed description of the invention
Fig. 1 is the utility model motor and impeller installation diagram；
Fig. 2 is Section A-A figure in Fig. 1；
Fig. 3 is the utility model blade wheel structure figure.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art institute without making creative work
The every other embodiment obtained, fall within the protection scope of the utility model.
See Fig. 1 to 3, a kind of motor and impeller installing, including motor 1, impeller 2, motor 1 include rotor case, leaf
The middle part of wheel 1 is provided with a cavity with opening, and the wheel cavity bottom is provided with positioning column 21, and the motor turns
Sub- shell is provided with the location hole matched with positioning column, and 21 top of impeller positioning column is arranged to wedge, the impeller cavity
Prominent muscle 22 is provided on the inner sidewall of body, the opening of the wheel cavity is provided with grab 23.
The motor rotor shell is mounted in wheel cavity, wherein the positioning column 21 of impeller 2 is inserted into location hole, institute
The end face that impeller grab 23 is caught in motor rotor shell is stated, the prominent muscle 22 is contacted with motor rotor shell, for consolidating horse
Up to the assembly of rotor case and impeller.
The positioning column 21 realizes that motor and impeller 2 are radially fixed, and grab 23 can realize motor and 2 axial restraint of impeller.
The prominent muscle 22, can make the close fit of impeller 21 and rotor case, reach axially and radially while consolidating and match
The purpose of conjunction.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
