--Key Type

Product Description 产品描述

It is applied mainly to wind shaft, or unwind shaft in special occasions.

The body is made from chrome-plate steel or hard anodized aluminum. The friction plate can be made from polyurethane, polyethylene, or rubber to max tension required.

To meet our customers’ special requirements, according to the drawing, we can make steel shaft head with different sizes.

滑差式气胀轴主要应用于收卷轴，特殊场合也用于放卷轴。

产品本体由镀铬钢或硬氧化铝制作，摩擦条可用聚氨酯、聚乙烯或橡胶材料制作，具体依据最大张力要求而定。

为满足客户的特别要求，可以按照客户图纸要求制定不同尺寸的钢轴头。

Feature 特性

Difference in material thickness often arises when unwinding plastic films or other material. In the process of constant winding, this difference can lead to obvious discrepancy in outside diameter of roll, and slight discrepancy in winding torque under this situation.

After some winding rotation, some rolls may become very tight, and meanwhile, some other rolls may start to loosen, leasing to quality decline in product eventually.

Our differential air shaft with slipping friction can ensure the highest winding quality, and by keeping proper tension on all rolls throughout the winding operation, materials will not show any problem.

It works under the theory that friction rings slip constantly in center of air shaft, and to keep same tension, some rings slip faster than others. So tension of each roll can be controlled accurately, and permanent tension can also be gained to guarantee the quality of roll.

According to different roll diameters, to control air pressure of air bag and to guarantee tension, a constant air pressure source kept by rotary joint is required.

当塑料膜或其他材质放卷时，材料的厚度会有差异。在不断收卷过程中，这种差异会导致明显的料卷外径差异，在这种情况下，所需的绕卷扭矩会稍有不同。

在几次绕卷旋转后，一些料卷可能会变得很紧，同事其他料卷会开始松弛，最终使产品的质量下降。

我们的滑差轴可以保证最高料卷质量，通过在卷轴运行时保持所有料卷适当的张力，材料不会产生问题。

工作原理在于滑差环在气胀轴中心持续滑动，为保证张力一致，一些轴环会较其他轴滑动更快。从而精确地控制每一卷材料的张力，得以恒张力卷取，保证了料卷质量。

根据不同的轴径，为了控制气囊中的气压和保证张力，需要旋转式接头来恒定气压来源。
