Sound.
Further, in conjunction with shown in Figure 14, bearing seal cover 18, the bearing seal cover 18 are provided on the bearing 2
Between the outer sleeve 5 and the integral type inner sleeve 14, for sealing the moving region of the bearing 2, and then make institute
Stating bearing 2 becomes sealing bearing, avoids dust from entering inside the bearing 2, reduces the generation of noise, make in the bearing 2
Lubricating oil is longer using the time, avoids often refueling, improve service life.
The integral type inner sleeve 14 can reduce the fan blade with first shaft part 15 integrated molding and connect with bearing
The amount of parts of structure reduces matching relationship, and then reduces the connecting portion for generating noise；Make the bearing 2 directly and institute
The connection of fan blade end axis 4 is stated, and type of attachment is the clearance fit of polygon, guarantees the stability of connection, reduces production cost.
Preferably, be additionally provided with the second shaft part 16 on the integral type inner sleeve 14, by the integral type inner sleeve 14 its
Second shaft part 16 is extended in middle one end end face first in the axial direction, and then extends first shaft part 15；
That is, along same axis direction, the integral type inner sleeve 14, second shaft part 16, first shaft part 15 according to
Sequence setting；
The integral type inner sleeve 14, second shaft part 16, first shaft part 15 are integrally formed；
Second shaft part 16 is set as circular shaft form, between the integral type inner sleeve 14 and first shaft part 15
Between, and directly engaged with the integral type inner sleeve 14, second shaft part 16 uses circular shaft form, and it is easy to process, it avoids
Processing difficulties caused by the integral type inner sleeve 14 is directly engaged with first shaft part 15 of polygonal in form.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
