Product Description

Introduction:

The slip shaft (slip type air expansion shaft) is mainly composed of mandrel, air bag, slip sleeve and other parts. The air expansion shaft has special sections, independent slip and torque setting structure, and is mainly used for high quality requirements of slitting products. , In the faster slitting equipment. The slip shaft (slip type air expansion shaft) is characterized by very small winding width but high winding precision requirements. It is mainly widely used in coating machines, slitting machines and other equipment. When customizing this kind of slip inflatable shaft, specific requirements such as outline dimensions, air nozzle position, tolerance level, etc. must be provided. Generally, the production is based on the drawings provided by the customer.

Outer diameter of 3inch differential air shaft = Φ75mm, maximum expansion diameter = 78 mm

1.3" differential shaft is consist of various 3" friction rings,please see pictures;

2. Applicable inner diameter of paper tube=Φ76mm

3. Standard friction ring's width 25mm, other width: 25mm, 30mm, 35mm, 40mm, 50mm. Optional

4. Standard inner diameter of friction ring φ60, other sizes can be made with the shaft center/axle.

5.If CORE ID of customers are not standard,or can not be confirmed,please send us the sample tube for measuring;

6.If CORE of customers are plastic tube,please measure the Core ID accurately.

The ball type differential air shaft controls the expansion by air pressure,usually the friction shaft is equipped with three flat bladders, and the flat airbag uses imported rubber materials, so it is largely help for product quality. The specifications of slip shaft bladders are mainly divided into two types: 15mm*1.5mm, 20mm*1.5mm, while their width is fixed, and the thickness may vary according to different manufacturers. Therefore,one of the most important part of differential shaft is the flat bladder, because in the case of high-speed friction, the flat bladders of slip shaft needs to withstand high temperature, etc., so the requirements for flat bladders are very high.

 

Technique parameter

Model	Paper tube inner diameter	Shaft diameter before expanding	Shaft diameter after expanding
2" Differential Shaft	Φ50.8mm	Φ50mm	Φ52mm
3" Differential Shaft	Φ76.2mm	Φ75mm-Φ75.5mm	Φ78.5mm
6" Differential Shaft	Φ152.4	Φ151mm	Φ156mm

The slip shaft is also called the slip type inflatable shaft, differential shaft, sliding shaft, friction shaft, friction shaft. It is mainly used for rewinding of slitting machine, and also used for unwinding in special occasions. The purpose is to use the principle of slippage of each slip ring on the slip shaft to make multiple rolls of material on the shaft and always maintain a stable tension for rewinding and unwinding.
