Air Shafts Chucks

Application of expansion sleeve in machinery industry

Expansion joints have the following advantages: high precision in alignment; easy installation/adjustment/disassembly; high strength, stable and reliable coupling; protection against damage during overload, especially for heavy loads. Widely used in heavy machinery, light industrial machinery, food machinery, packaging machinery, textile machinery, printing machinery, CNC machine tools, automation equipment, etc. (heavy machinery holds the shaft).

The use and joint advantages of the expansion sleeve: When the load is applied, the combined pressure of the expansion sleeve and the mechanical part and the shaft and the accompanying friction force transmit the torque, the axial force or the combined load of the two.

Expansion sleeve (also known as expansion joint sleeve, keyless bearing, etc.) is a keyless coupling device whose principle and use is through the action of high-strength tension bolts between the inner ring and the shaft, between the outer ring and the hub. A great grip is created to achieve a keyless connection between the machine and the shaft.

Air shafts chucks has a wide range of applications and can be used in drum winding and unwinding equipment and assembly lines, such as papermaking machinery, plastic film making machinery, coating machine, laminating machine, rotary printing machine, slitting machine, and system. Plate, foil, film, leather, coating, laminating paper tube machine, textile, printing and dyeing, cigarette, carpet and other industries have been widely used.

Technique parameter

Inflatable bushing factory, product specifications:
Divided into a key inflatable sleeve and a plate inflatable sleeve.
Common specifications are: 3 inches to 6 inches, 3 inches to 8 inches, 3 inches to 10 inches, 3 inches to 12 inches. After inflation, the diameter increased by 8mm. The length is 200 mm, 250 mm, 300 mm, 400 mm, 500 mm, etc. (Can be customized according to customer needs, length and length) inflatable sleeve clamp technical parameters: gas rise sleeve body outer diameter Φ150mm, action outer diameter Φ155mm, applicable paper tube Φ149-153mm, 201-205mm, 252-256mm, 302-305mm The body length is 200mm, 250mm, 300mm, 400mm, 500mm, etc.

Application of inflatable sleeve clamp: It can be fixed at any position of the inflation shaft to facilitate winding and unwinding. The riser sleeve is suitable for the retracting of related machinery such as coating, printing, rewinding, paper making and plastics. Structural features: The gas riser sleeve mainly consists of front sleeve, rear sleeve, cylinder, inner tube, airbag and convex keyboard. The riser material is made of aluminum, the surface is oxidized, and the airbag and quick inflation nozzle are arranged. Good sealing effect, long service life and convenient maintenance.
