Description
Technical field
It the utility model is related to oilless air compressor technical field, and in particular to a kind of airborne direct current oilless air compressor.
Background technology
Oilless air compressor is China's one of industrial best energy saving environmental protection product at present, and it is widely used in not going together
Industry, oilless air compressor need not dose any lubricating oil and can work；The air of discharge is free of oil content, solution oil removing to gas facility and
The worry of afterproduct pollution, oilless air compressor externally provides compressed gas, will not because of the pressure loss that waste-oil scavenger is brought and
Motor load is substantially reduced, reaches energy-saving effect, oilless air compressor need not dose any lubricating oil and can work；The air of discharge
Without oil content, solution oil removing is to the worry with gas facility and afterproduct pollution；Environmental protection and social benefit are splendid, but existing direct current
Oilless air compressor be not particularly suited for the Aero-Space such as helicopter use because the aerospace vehicle such as helicopter have to weight it is strict
It is required that the payload of the aerospace vehicles such as helicopter can be effectively improved by mitigating airborne equipment weight, thus to each equipment
Part has a strict weight limitation, and be required to equipment can be in -40 DEG C to 60 DEG C environment for the aerospace craft such as helicopter
Upper normal use, and existing oil-free only has air compressor machine and is unsatisfactory for the demand of helicopter.
Utility model content
Technical problem to be solved in the utility model is to be directed to above-mentioned the deficiencies in the prior art,
A kind of airborne direct current oilless air compressor is provided.
To achieve the above object, the utility model provides following technical scheme：A kind of airborne direct current oilless air compressor,
Include casing, it is characterised in that：The casing center is provided with insertion shaft type direct current permanent magnetic brushless motor, the insertion shaft type
Direct current permanent magnetic brushless motor is provided with output shaft, and described output shaft one end is provided with left fan, and the other end is provided with right fan, the left wind
The song made of PM technique is provided between fan and right fan and insertion shaft type direct current permanent magnetic brushless motor on output shaft
Handle, the crank are provided with boss, and pressing plate made of high polymer material is socketed with outside the boss, height is connected with above the pressing plate
Connecting rod made of molecular material, the connecting rod are provided with sound insulation wing, and being provided with air pressure above the connecting rod occurs machine.Above-mentioned one kind
Airborne direct current oilless air compressor can be further arranged to：Machine, which occurs, for the air pressure includes being arranged at casing top by high polymer material
Manufactured valve plate, the valve plate top are provided with the cylinder cap made of high polymer material, and the valve plate is provided with cylinder cap connecting hole, described
Cylinder cap is provided with cylinder cap mounting hole in cylinder cap connecting hole opposite position, is provided with the cylinder cap mounting hole and is made up of high polymer material
Screw.
A kind of above-mentioned airborne direct current oilless air compressor can be further arranged to：Sky is provided between the valve plate and connecting rod
Gap, cylinder seal circle is provided with the space.
A kind of above-mentioned airborne direct current oilless air compressor can be further arranged to：Cylinder cap connection hole number on the valve plate
For four.
A kind of above-mentioned airborne direct current oilless air compressor can be further arranged to：Described high polymer material is polyethers ether
Ketone.
Using above-mentioned technical proposal, because the utility model is used in aviation field, therefore for air compressor machine itself
Noise, weight, use environment temperature there are rigors to require, the sound insulation wing set on connecting rod can be played preferably
The effect of noise is absorbed, because motor needs metal material to form magnetic field, therefore motor can not be substituted for polyether-ether-ketone
Material, so have to be improved from other critical pieces, therefore the connecting rod of air compressor machine, cylinder cap, valve plate, connecting bolt is equal
Change into by peek（Polyether-ether-ketone）Material is made, and is formed from aluminium because the linkage component of air compressor machine on the market is adopted mostly, the ratio of aluminium
Weight is 2.7g/cm3, and the proportion of peek materials is 1.29g/cm3, therefore is only original using connecting rod weight made of peek materials
The 1/2 of first aluminium connecting rod, and polyether-ether-ketone has rigidity and flexibility, it is particularly very prominent to the fatigue resistance under alternate stress
Go out, can be compared favourably with alloy material, therefore connecting rod made of use peek materials is not only in light weight and service life is longer, originally
Crank is made using gray cast iron, the proportion of gray cast iron is 7.35g/cm3, is substituted for weight after the material of PM technique processing
Less than original 60%, and screw originally was made using stainless steel 304 material, the proportion of stainless steel 304 is 7.93g/cm3, is replaced
Weight is less than original 1/4 after into screw, and peek materials possess excellent sliding properties in itself, using in oilless air compressor
Deduct a percentage significantly the service life of each part, and alleviate the weight of each part.
The beneficial effects of the utility model are：The deadweight of oilless air compressor is significantly reduced, each part is improved and uses the longevity
Life, reduces noise, meets the harsh working environment of airborne air compressor machine.
The utility model is described in further detail with reference to the accompanying drawings and examples.
