Description
Technical field
The present invention relates to a kind of anti-eccentric system of single shaft, especially a kind of anti-eccentric body of single shaft for small-sized fans bearing
System.
Background technique
After traditional miniature motor axle sleeve uses the time longer, it is easy to happen discontinuity equalization, causes flabellum eccentric,
It generates loud noise or a direction stress is excessive, be easily deformed and not resilient, lead to bias.Excentric sleeve drives
Flabellum rotates in cycles, can generate very big noise, brings very big inconvenience to studying and living, makes one to have focused on
It is especially larger or for a long time use in axle sleeve stress at task, when toppling over or collide with other sundries such as fan, it is easy eccentric produce
Raw noise, brings puzzlement to the environment to need peace and quiet, when cannot have excessive noise, as when classroom, which is attended class, to learn, and books
Shop individual reads or domestic fan.As people's lives quality is higher and higher, the requirement to substance is also higher and higher, purchase electricity
During device, people increasingly pay attention to muting function, since traditional miniature motor is easy to produce noise, so that its market accounts for
Have that rate is lower and lower, it is not high so as to cause conventional small motor axle sleeve practical value.
Summary of the invention
The object of the present invention is to provide a kind of anti-eccentric systems of single shaft for small-sized fans bearing.Structure of the invention
Simply, using both ends force balance, expanding drag axle center radius prevents bias by the shape control of axle sleeve in very low range,
Loud noise is generated after can working long hours to avoid fan.
Technical solution of the present invention: a kind of anti-eccentric system of single shaft for small-sized fans axle sleeve, includes inverted U-shaped fan
Leaf shell is provided with flabellum on the external shell of fan blade housing, is from top to bottom disposed with the first convex inside fan blade housing
Plastic part, circular ring shape plastic part and the second convex plastic part, the first convex plastic part and the second convex plastic part are oppositely arranged,
Protruding end is caught in the circular hole of circular ring shape plastic part, and screw sequentially passes through downwards fan blade housing, first convex at the top of the fan blade housing
After shaping materials and parts and circular ring shape plastic part, penetrates and fix 4 parts into the second convex plastic part, the first convex plastic part
Center is provided with screw-threaded counterbore from its protruding end is inward-facing, and the second convex plastic part is provided centrally with tapped through hole.
Be previously described in the anti-eccentric system of single shaft of small-sized fans axle sleeve, the fan blade housing, the first convex plastic part,
Multiple threaded holes are evenly arranged on circular ring shape plastic part and the second convex plastic part.
It is previously described in the anti-eccentric system of single shaft of small-sized fans axle sleeve, the thickness of the circular ring shape plastic part is greater than etc.
In the sum of the first convex plastic part and the second convex plastic part convex portion height.
It is previously described in the anti-eccentric system of single shaft of small-sized fans axle sleeve, the Circularhole diameter etc. of the circular ring shape plastic part
In the diameter of the first convex plastic part and the second convex plastic part convex portion.
Beneficial effects of the present invention: compared with prior art, the present invention is by using being oppositely arranged the first convex plastic part
With the second convex plastic part, and it is caught in its convex portion in circular ring shape plastic part, two blocks of raised plastics form two effects
Supporting point, so that whole stability under loading and balance, while a degree of radius for expanding entire component, to improve structure
Part is to the ability of the resistance to deformation of external force, by the shape control of axle sleeve in very low range.The configuration of the present invention is simple prevents partially
The heart prevents fan from working long hours and generates loud noise.Whenever people, which can experience, is not influenced band by fan low noise
The comfort come most importantly greatly mitigates noise and perplexs state to bring irritability in work and study.Have and pushes away well
Wide and practical value can generate good economic benefit and social benefit after extensive popularization and application.

Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples, but be not intended as to the present invention limit according to
According to.
The embodiment of the present invention: a kind of anti-eccentric system of single shaft for small-sized fans axle sleeve, as shown in attached drawing 1-5, packet
1 inverted U-shaped fan blade housing 2 is included, is fixedly uniformly arranged with multiple flabellums 1, fan blade housing on the external shell of fan blade housing 2
The first convex plastic part 5, circular ring shape plastic part 6 and the second convex plastic part 4 are from top to bottom disposed with inside 2, first is convex
The protruding end for shaping materials and parts 5 and the second convex plastic part 4 is oppositely arranged, and protruding end is caught in the circular hole of circular ring shape plastic part 6
In, screw 3 sequentially passes through downwards fan blade housing 2, the first convex plastic part 5 and circular ring shape plastic part 6 from 2 top of fan blade housing
Afterwards, it penetrates and fixes 4 parts into the second convex plastic part 4.First convex plastic part, 5 center, from its protruding end towards
It is inside provided with screw-threaded counterbore, the second convex plastic part 4 is provided centrally with tapped through hole.In use process, by motor rotation axis 8
After being threaded into from the tapped through hole of the second convex plastic part 4 of bottom, then it is threaded into the screw-threaded counterbore of the first convex plastic part 5
In, so that entire anti-eccentric system be connected with the other components of fan.
It is uniformly set on the fan blade housing 2, the first convex plastic part 5, circular ring shape plastic part 6 and the second convex plastic part 4
It is equipped with multiple threaded holes 7.Screw 3 passes through for all parts to be locked together from the threaded hole 7 of each component, screw thread
Hole 7 is uniformly distributed, and guarantees that various pieces can lock connection well.
The thickness of the circular ring shape plastic part 6 is more than or equal to 4 lug boss of the first convex plastic part 5 and the second convex plastic part
Divide the sum of height.The setting can make the first convex plastic part 5 and 4 convex portion of the second convex plastic part be caught in annulus shaped plastic
After in the circular hole of materials and parts 6, the surface of the first convex plastic part 5 and the second convex plastic part 4 can be with the table of circular ring shape plastic part 6
Face fits closely together, constitutes 1 complete entirety.
The Circularhole diameter of the circular ring shape plastic part 6 is equal to 4 lug boss of the first convex plastic part 5 and the second convex plastic part
The diameter divided.The setting is also in order to enable the first convex plastic part 5, the second convex plastic part 4 and circular ring shape plastic part 6 are mutual
Connection procedure realizes seamless connection, it is complete whole to constitute 1, while gap being not present between each other, screw 3 is also facilitated to wear
Enter, assembles more convenient.
