Difference Between Differential Shafts And Core Shafts?

The most common differential shaft and the core shaft used in the market today are both inflated.

First of all, the main axis of the air expansion shaft is still the traditional one. 

The circular expansion of the rubber airbag is used to control the expansion and contraction, 

and finally the customer's use requirements are met. The accuracy of the inflation shaft is relatively poor. The bearing capacity is also relatively poor, and it is a product with high precision.

In recent years, many companies that are increasingly demanding products have begun to use the continuous lug type air shaft, which consists of several equal-part rubber key strips around the circumference. The underside of the key strip is relative to the flat. The airbag, which is composed of a plurality of flat airbags corresponding to the key strips, even if one of the airbags leaks, in the state of automatic inflation, if it is not particularly leaky, it can be temporarily used for a while. The rubber shaft of the rubber strip is better in precision than the ordinary air expansion shaft, and the product strength is also stronger.

The central air pressure slip shaft is a product with higher precision and better performance than the rubber shaft. The air expanding axis is the constant tension of the whole shaft, and the tension cannot be eliminated. Therefore, during the slitting and winding process, the air expanding shaft will encounter the end of the product that is finally wound up, and the coil material is not tight, which is the phenomenon. The defects of the structure of the inflatable shaft itself cannot be overcome by themselves. The slip shaft is an upgraded version of the air shaft, which was developed to overcome the shortcomings of the air shaft. When the slip shaft is slitting and winding the material, the individual slip ring on the slip shaft will adjust itself according to the tension of each roll of material, and the slip ring will slip with the shaft core to finally eliminate the tension and achieve a stable collection. Volume effect. The center air pressure slip shaft controls the tension by adjusting the air pressure. Now many good slitting machines have a pneumatic system, which will automatically adjust the air pressure according to the increase of the material coil diameter to achieve the effect of increasing the tension. The axis of the slip shaft is the same as the air-expansion shaft of the key-bonding strip. There are also several flat airbags on the circumference. Under the protection of the wool felt, it is in contact with the inner hole of the slip ring. The higher the air pressure, the tighter the support, and our gas The expansion shaft is constant pressure constant tension. Therefore, due to the uneven thickness of the coil or the influence of external factors, the winding is not neat and the tension is not the same. In a word, to be very ideal for winding, the slip shaft is definitely the right choice.
