For installation axle 28 vertically to arrangement, the lower end of the installation axle 28 is fixing end, integrated with internal rotor to be installed on blade
Blower 100 lower cover 3 on；The rotational installation of rotor hub 21 is in the installation axle 28.Under right angle setting environment, lead to
The firm installation that the fixed mode in lower end achieves that internal rotor component is crossed, and the lower end of the installation axle 28 is fixedly mounted on
The lower cover 3, rather than lower cover 3 is rotatably installed in using installation axle 28, and then be arranged not necessarily at the lower cover 3
Bearing 29 is installed for the installation axle 28, and then lower cover 3 can be set more simple, and lower end is fixed, and upper end suspends, and
Unnecessary setting upper end cover.
Further, the rotor hub 21 has the mounting hole that is set in the installation axle 28, in the mounting hole
Equipped with bearing 29, the rotor hub 21 is rotatablely installed by the bearing 29 in the installation axle 28.The multiple bearing 29
Additional axial space is prevented take up positioned at the annular gap, so that the blade and the integrated blower 100 of internal rotor can
To further decrease.
Also, mounting structure of the installation axle 28 as the internal rotor component, is fixed, the installation axle using lower end single-point
28 can, easier circular runouts poorer further away from lower end supporting point intensity, thus in order to enhance the installation axle 28 intensity and
Stability avoids installation axle 28 in the internal rotor component rotation process, radial direction to deform and cause it is described in turn
It moves component circular runout and influences stability, the installation axle 28 is set as being set as overstriking setting under, it is of course also possible to
It is to set the internal rotor component and 22 at least one of them of the blade to be set as aggravating setting from top to bottom, and make
The center of gravity for the rotating member that the internal rotor component and the blade 22 form makes the rotation of rotating member closer to lower supporting point
Stability is good.
The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model,
Under all utility models in the utility model are conceived, equivalent structure made based on the specification and figures of the utility model
Transformation, or directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
