Abstract
A kind of improved electric motor type air pump gear, including eccentric wheel, rocker power transmission shaft, rocker, rocker axle sleeve；Described eccentric wheel, spindle hole is provided with, is fixed with rocker power transmission shaft, described spindle hole and rocker power transmission shaft form an angle, between 10 20 degree, described rocker power transmission shaft is metalwork, and described rocker is provided with multiple cylinder torque arm, and center is fixed with rocker axle sleeve, described rocker axle sleeve is metalwork, described rocker power transmission shaft insertion rocker axle sleeve, when eccentric wheel rotates with electric machine main shaft, is driven to rocker.The utility model has the advantages that：Because rocker power transmission shaft, rocker axle sleeve are metalwork, so that friction during transmission is carried out between metal shaft and metal axle sleeve, it is worn the situation of abrasion so as to avoid eccentric wheel axis hole in the prior art, it is also beneficial to the long-time continuous use of air pump, extend the use range of air pump, the job stability of air pump is improved, extends the service life of air pump.
Description
Technical field
It the utility model is related to air pump field, more particularly to a kind of improved electric motor type air pump gear.
Background technology
Existing electric motor type air pump, its transmission device all on electric machine main shaft as shown in figure 1, install plastic eccentric wheel（1）,
By being arranged on eccentric wheel（1）The axis hole that upper and electric machine main shaft forms an angle（5）, set, which connects, is fixed on rocker（3）Center
Metal rocker axle（2）It is driven, drives rocker（3）Cyclic tension motion is made to multiple rubber cylinders, so that gas is continuous
Pump out.It is existing this with plastic eccentric wheel upper shaft hole, entangle and be fixed on metal rocker shaft drive on rocker, due to being
Friction between plastic eyelet and metal shaft, such as long time continuous working, and easily heating, axis hole（5）Easily it is worn, so that gas
Pump vibrates at work and noise increase, also shortens the service life of air pump.
The content of the invention
The defects of for above-mentioned prior art, the utility model provide a kind of improved electric motor type air pump gear, made
Friction when must be driven is carried out between metal and metal, and so as to avoid the abrasion of axis hole, the long-time for being advantageous to air pump is continuous
Use, extend the use range of air pump, improve the job stability of air pump, extend the service life of air pump.
In order to solve the defects of prior art, this practicality is new to be with the technical scheme used：A kind of improved electric motor type gas
Pump drive assembly, including eccentric wheel, rocker power transmission shaft, rocker, rocker axle sleeve；Described eccentric wheel, spindle hole is provided with, it is fixed
There is rocker power transmission shaft, described spindle hole and rocker power transmission shaft form an angle, between 10-20 degree, the transmission of described rocker
Axle is metalwork, described rocker, is provided with multiple cylinder torque arm, and center is fixed with rocker axle sleeve, and described rocker axle sleeve is
Metalwork, described rocker power transmission shaft insertion rocker axle sleeve, when eccentric wheel rotates with electric machine main shaft, is driven to rocker.
The utility model has the advantages that：It is all metalwork because rocker power transmission shaft is fixed on eccentric wheel, and with rocker axle sleeve so that pass
Friction when dynamic is carried out between metal shaft and metal axle sleeve, because metal axle sleeve is wearing piece, so as to avoid prior art axis
The abrasion in hole, be advantageous to the long-time continuous use of air pump, extend the use range of air pump, extend the service life of air pump
And job stability.
Brief description of the drawings
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present utility model.
Embodiment
2 pairs of specific embodiment of the present utility model are described as follows with reference to the accompanying drawings：
As shown in Fig. 2 a kind of improved electric motor type air pump gear of the utility model, including eccentric wheel（1）, rocker pass
Moving axis（2）, rocker（3）, rocker axle sleeve（4）；Described eccentric wheel（1）, it is provided with spindle hole（5）, it is fixed with rocker power transmission shaft
（2）, described spindle hole（5）With rocker power transmission shaft（2）Form an angle, between 10-20 degree, described rocker power transmission shaft
（2）For metalwork, described rocker（3）For disc, outer is provided with multiple cylinder torque arm（6）, center is fixed with rocker axle
Set（4）, described rocker axle sleeve（4）For metalwork, described rocker power transmission shaft（2）Insert rocker axle sleeve（4）, work as eccentric wheel
（1）When being rotated with electric machine main shaft, to rocker（3）It is driven.
The utility model has the advantages that：Due to rocker power transmission shaft（2）, rocker axle sleeve（4）It is all metalwork so that during transmission
Friction carried out between metal shaft and metal axle sleeve, so as to avoid the situation that eccentric wheel upper shaft hole is worn in the prior art,
Be advantageous to the long-time continuous use of air pump, extend the use range of air pump, improve the job stability of air pump, extend
The service life of air pump.
