Abstract
This utility model provides the fixed structure of a kind of centrifugal blower motor shaft, belongs to blower fan technical field.It solve existing centrifugal blower bearing easily to wear and tear the big problem of noise.The fixed structure of this centrifugal blower motor shaft, this centrifugal blower includes spiral case, motor and impeller, motor is fixed on the side of spiral case by support, the motor shaft of motor is fixedly connected with impeller in penetrating spiral case, spiral case is provided with air outlet and air inlet, air inlet is circumferentially uniform along air inlet edge is fixed with several bracing frames, and the outside being provided centrally with bearing block and bearing block of air inlet is fixedly connected with each bracing frame, and the end of motor shaft is connected with the bearing in bearing block.It is little the most easy to wear that this utility model has motor shaft vibration amplitude, the advantage that muting function is good.
Description
Technical field
This utility model belongs to blower fan technical field, relates to a kind of centrifugal blower, particularly to a kind of centrifugal blower motor
The fixed structure of axle.
Background technology
Centrifugal blower is the principle being converted to potential energy according to kinetic energy, utilizes the impeller of high speed rotating to accelerate then to subtract by gas
Speed, change the driven fluid machinery flowing to finally discharge from air outlet, in centrifugal blower, gas from axially into impeller, by
Applying gas in centrifugal force is radially redirected when flowing through impeller, is then slowed down by volute of blower decompression and discharges.Tradition at present
Centrifugal blower be typically all motor shaft and be directly connected with impeller, and motor shaft ends is all the most unsettled not have fixing device,
Blower fan is in running, and the vibration amplitude of motor shaft is relatively big, makes fan bearing easily wear and tear, and the noise produced is bigger.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, it is provided that one can effectively reduce
Motor shaft vibration amplitude so that it is the fixed structure of muting function more preferable centrifugal blower motor shaft.
The purpose of this utility model can be realized by following technical proposal: the fixed knot of a kind of centrifugal blower motor shaft
Structure, this centrifugal blower includes spiral case, motor and impeller, and described motor is fixed on the side of spiral case, described motor by support
Motor shaft penetrate and be fixedly connected with impeller in spiral case, described spiral case is provided with air outlet and air inlet, it is characterised in that described
Air inlet along air inlet edge circumferentially uniform several bracing frames that is fixed with, described air inlet be provided centrally with bearing
The outside of seat and described bearing block is fixedly connected with each bracing frame, and the end of described motor shaft is connected with the bearing in bearing block.
The principle of the fixed structure of this centrifugal blower motor shaft is: by being fixed with bearing in air inlet by bracing frame
Seat, makes the motor shaft ends of motor be connected with bearing block, and motor shaft can be made to effectively reduce its vibrations width in rotation process
Degree, makes the bearing of blower fan be not easy abrasion, and muting function is more preferable.
In the fixed structure of above-mentioned a kind of centrifugal blower motor shaft, described bracing frame number is more than or equal to 3.
In the fixed structure of above-mentioned a kind of centrifugal blower motor shaft, described motor is threephase asynchronous machine.
Compared with prior art, this centrifugal blower is by fixing motor shaft ends so that it is have muting function good and
The nonabradable advantage of bearing.

Detailed description of the invention
The following is specific embodiment of the utility model and combine accompanying drawing, the technical solution of the utility model is made further
Description, but this utility model is not limited to these embodiments.
As shown in Figure 1 and Figure 2, the fixed structure of this centrifugal blower motor shaft, this centrifugal blower includes spiral case 1, motor 2 and
Impeller 3, motor 2 is fixed on the side of spiral case 1 by support, and the motor shaft 4 of motor 2 is fixedly connected with impeller 3 in penetrating spiral case 1,
Spiral case 1 is provided with air outlet 5 and air inlet 6, at air inlet 6 along air inlet 6 edge circumferentially uniform be fixed with several support
Frame 7, the outside being provided centrally with bearing block 8 and bearing block 8 of air inlet 6 is fixedly connected with each bracing frame 7, the end of motor shaft 4
It is connected with the bearing in bearing block 8.
Describing in detail further, bracing frame 7 number is more than or equal to 3, and motor 2 is threephase asynchronous machine.
Specific embodiment described herein is only to this utility model spirit explanation for example.This utility model institute
Belong to those skilled in the art described specific embodiment to make various amendment or supplement or use similar
Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
Although the most more employing spiral case 1, motor 2, impeller 3, motor shaft 4, air outlet 5, air inlet 6, bracing frame
7, the term such as bearing block 8, but it is not precluded from using the probability of other term.These terms are used to be only used to more easily
Describe and explain essence of the present utility model；Being construed as any additional restriction is all and this utility model spirit
Contrary.
