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.
