Description
Technical field
The utility model relates to a kind of appurtenances structure of centrifugal blower, specifically a kind of motor direct connection fan is anti-
Leakage structure.
Background technique
Currently, the leakage of centrifugal blower is an important factor for influencing fan efficiency, especially for the blower of direct connection structure
For connecting with motor, the wind of blower is easy to out of shell let out by the main shaft of motor, for such leakage, by
In technically there are obstacles, always in the presence of two uncontrollable contradictions, i.e. pursuit anti-leak result then increases device volume
And structural complexity, pursuing structure simply then reduces sealing effect and use occasion by significant limitation.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of structure is simple, sealing effect is good and to adapt to operating condition extensive
Motor direct connection fan leakage-proof structure.
In order to solve the above-mentioned technical problem, the motor direct connection fan leakage-proof structure of the utility model, including for installing
The electric machine main shaft of impeller assembly and the Blower Housing that impeller assembly periphery is arranged in are provided with for concatenating electricity on Blower Housing
The concatenation hole of owner's axis concatenates in hole and is fixedly installed with elastomeric pad, and elastomeric pad includes for Blower Housing and motor master
Axis carries out the ring packing end of elastic packing and is integrally disposed upon the flanged ends of ring packing end side, elastomeric pad from
It is fixedly mounted with Blower Housing on the inside of Blower Housing and ring packing end cap is made to stretch out Blower Housing simultaneously on electric machine main shaft
Outside.
The elastomeric pad is nylon spacer.
Mounting hole is placed on the flanged ends.
Outer 2~the 3mm of Blower Housing is stretched out at the ring packing end.
It is fixedly connected by rivet across mounting hole between the flanged ends and Blower Housing.
It is interference fitted between the elastomeric pad and electric machine main shaft.
After above-mentioned structure, since what is be fixedly mounted in the concatenation hole of Blower Housing has flanged ends and annular
The elastomeric pad and ingehious design of sealed end elastomeric pad it is specific with Blower Housing fixed installation on the inside of the Blower Housing
Structure, thus on the one hand, mounting means is simple, does not need the length for increasing electric machine main shaft, that is, uses the motor of general type
, economic benefit and operation convenience are improved, the structure especially installed on the inside of Blower Housing also effectively prevents electricity
On rear side of machine direct connection fan blow-by or sealing effect it is improper and caused by outside fan efficiency decline and the dust for passing through blower interior
Ease, still further aspect, the elastomeric pad for being interference fitted installation make sealing very reliable, and anti-leak result is good, structure design
Simple ingenious, fabrication and installation are convenient, and sealing effect is ideal, can especially take into account structure and sealing effect, and it is extensive to adapt to operating condition.
Detailed description of the invention
Fig. 1 is the installation condition schematic diagram of the utility model motor direct connection fan leakage-proof structure；
Fig. 2 is enlarged structure schematic diagram at the A of Fig. 1.
Specific embodiment
With reference to the accompanying drawings and detailed description, the motor direct connection fan leakage-proof structure of the utility model is made into one
Step is described in detail.
As shown, the motor direct connection fan leakage-proof structure of the utility model, including the electricity for installing impeller assembly 1
Owner's axis 2 and the Blower Housing 3 that impeller assembly periphery is arranged in are provided with for concatenating electric machine main shaft on Blower Housing 3
Hole is concatenated, concatenates and is fixedly installed with elastomeric pad 4 in hole, elastomeric pad 4 is preferably nylon spacer, it is contemplated that durability and Ke Jia
Drum selects trade mark PA6, and the comprehensive performance of the material is preferable, and elastomeric pad 4 includes for Blower Housing and electric machine main shaft
It carries out the ring packing end 5 of elastic packing and is integrally disposed upon the flanged ends 6 of ring packing end side, flanged ends
It is placed with mounting hole on 6, is fixedly connected by rivet across mounting hole between flanged ends 6 and Blower Housing 3, passes through
Test can be fixed very well using 4 self-plugging rivet installations, and elastomeric pad 4 is fixed on the inside of Blower Housing with Blower Housing
Install and make 5 sets of ring packing end on electric machine main shaft while stretching out outside Blower Housing 3, elastomeric pad 4 and electric machine main shaft 2 it
Between be interference fitted, the outer 2~3mm of Blower Housing is stretched out at ring packing end 5 after installation, to guarantee sealing effect well, effectively
The internal efficiency for improving blower, electric machine main shaft do not need to lengthen, increases the structural strength of blower, do not need individually to purchase axis
Nonstandard motor is lengthened, cost has been saved, the apparatus structure is simple, easily manufactured, it is only necessary to which Vehicle Processing and part pincers worker, installation is just
Victory facilitates stock, batch production and installation.
Furthermore it is also possible to which annular groove is arranged on electric machine main shaft 2, ring type seal, the thickness of ring type seal are disposed in annular groove
Degree is slightly larger than annular groove depth, and the surface of preferably greater than annular groove 1mm or so, ring type seal have pit and protrusion, in addition, annular
The width of sealing ring is less than the width at the ring packing end 5 of elastic packing, and the ring packing end 5 of elastic packing thus can be made complete
It covers outside ring type seal, thereby increases secondary seal effect, furthermore, it can also be directly at the ring packing end of elastic packing
The boss of 5 middle part setting convex, boss limit increase sealing effect in annular groove.
