Air Expanding Shaft with Differenct Type
|
For fast change over of un-winder/winder roll air expanding shafts are required for core holding. Through its air valve air can fill and the air shaft will hold the core by expanding the rubber bladder. Core gets released after removing the Air by thump press. Most commonly used cores are 3¡± ID core but bigger cores are also used where heavy weight of the unwind/re-wind rolls.
Air expanding shaft is core-holding device suitable for 3¡± core inside diameter & 6" core diameter. Lugs type Air expanding shaft is most commonly used for paper or PVC core holding. Square end Airshaft can be used with safety chucks for winding & winding. The shaft can take load of 30kgs to 500kgs. Cantilever type Airshaft is available with one side shaft for mounting. Air valve can locate at face length or shaft end according to requirements. In case of failure of air shaft rubber bladder your service mechanic can easily replace the tube at your place itself. Importance is given to valve fitting and Teflon tape sealing of valve thread and to avoid damage of ¡°O¡± rings. To avoid overfilling of air to avoid puncture of air bladder special air gun can be ordered with pressure so that know the in built air pressure inside the Air shaft. If require special Hardened ends, bearing size it should be mentioned in your order.

Expanding Core Shafts
For high speed and/or heavyweight applications requiring maximum torque capacity and minimum vibration.Mechanical design provides the most powerful gripping force possible.Activated by turning a crank (or impact wrench) that is inserted into the end of a journal.Requires just five cranks for full expansion ¨C lugs rise concentrically to center the carbon fiber shaft in the core, minimizing the roll bounce common with other types of expanding shafts.Mechanical and Pneumatic/Mechanical Shafts are also available in Double E's traditional steel design.
SUNRISE Double Shafts Magnetic Powder Clutch With High Quality
PC magnetic particle clutch work principle:
Magnetic particle clutch | brake is a type of auto-control component with high-performance which uses driving and driven units as main body, powder (magnetic powder) with high magnetic conductivity as working medium and exciting current as control means so as to achieve control transfer/braking torque and to keep the linear relationship between input current and output torque. With the development of the modern industry, it plays an increasingly important role in all industrial fields and demonstrates great advantages over other components. #magneticpowderclutch
The products are widely used in winding and unwinding starting/braking control, stamping startup, overload protection, position control, speed control, tension control, artificial load and relevant fast control systems.
Key type Air Expanding Shaft
Purpose
It is applicable to winding and unwinding shaft of the related machine in coating, cutting, compounding, paper making, bag making, plastic items, and it can improve the working efficiency effectively.Structual features
The main body of the shaft utilize the hard chromium plating sreel pipe; it has alumium sharps with flexible scalability; deploying high quality rubber bladder and rapid aerating and exhausting gas nozzle with good sealing effect and long service life; it has removable shaft with simple maintenance.
Delivery guide
Users should specify type, dimension, the position of gas nozzle, and the tolerance of the important size of the top of shaft. All formal drawing of overall dimension should be provided. After the confirmation of both sides, we will start production.
