Fabrication of air expansion shaft
- The gas expansion shaft (gas expansion shaft) is generally made according to the needs of the actual application. There is no standard part, and different types are selected according to the actual needs. Common types include aluminum alloy inflatable shaft, expanded key inflatable shaft and blade inflatable shaft, and some distinguish between metal and non-metal.
- Generally, the user designs the drawings of the inflatable shaft and provides them to the inflatable shaft manufacturer. At the same time, the customized requirements should be attached, such as the weight, materials and accuracy requirements of the inflatable shaft. The manufacturer will conduct technical evaluation according to the drawings and other requirements provided by the user before production.
- As a special equipment for winding and unwinding, air expansion shaft is usually used together with magnetic powder brake, magnetic powder clutch and tension controller. It is widely used, such as the winding and unwinding system of coating machinery, slitting machinery, cross cutting machinery, laminating machinery, film covering machinery, film blowing machinery, paper making machinery, non-woven fabric machinery, cloth inspection machinery, etc.
