1.What is Air Shaft
It is a kind of special-made shaft for winding or unwinding,when it inflated by high-pressure, the surface of it can be raised up and after deflating the air,the surface will quickly retract.It is widely used in the manufacturing process and light metal industry.The advantage of using an air shaft is that it can greatly improve the workingeffeciency .
2.What can an air shaft be used for
Bag making machine;
And so on.
3. Specifications of air shaft
Type:Key type air shaft(steel-made or aluminum made) ,Lath type air shaft,Differential air shaft
Material: No.45 steel/ Aluminum
Unaerated diameter (ømm)
Applicable volume tube inner diameter(ømm)
4.Why choose us?
(1)Adoping high power press machine to realize interference fit
We are using a high power press machine which can produce 80T thrust to realize all the combination of spindle head and steel tube for the air shafts. Light type air shaft is with 0.03mm interference fit.Heavy type air shaft is with 0.06mm interference fit.While many factories knock it in with a big hammer,no quality and accuracy.
(2)Adopting hi-precision cold-drawn steel tube as the shaft body
We adopt hi-precision cold-drawn steel tube as the shaft body.The thickness of this kind of tube is uniform so when the rubber balloon inside is inflated ,all key strips will stick out at same height .And it will greatly weaken centrifugal force of the whole air shaft when it is rotating and will keep a dynamic balance.
(3) Adopting whole long key bar and pagoda springs for key type air shafts
We use the whole long key bar to form a good protective ring around the air shaft air chamber ,and we adopt the pagoda springs which can bear 300000 compression.The key bar is made of aluminum alloy.
(4)Adopting special equipment to connect air chamber and shaft head
The connection mode between the air chamber and the shaft head is very important process,our company are using special equipment to realize it.Outside is buckled by siderosphere directly which can ensure good sealing performance and stability. Many air shafts produced by other suppliers , both ends are fastened by iron wire,this is easy to leak and is with unstable sealing performance.
