Air Chucks

The plate type air expansion shaft, the key type air expansion shaft and the slip air expansion shaft are relatively common air expansion shafts. Specifically introduce:
1. Plate type air expansion shaft: The plate type air expansion shaft expansion part is a plate piece, which can be applied to a machine with high precision of winding or a lighter winding item.
2: Key type air expansion shaft: The key type air expansion shaft expansion part is a key strip, which can be applied to items with heavy mechanical load capacity.
3: Slip gas rising shaft: Slip gas rising shaft has been widely used in plastic film, metal foil, paper roll; PVC sheet material is cut and wound.
Several items of external inspection of the gas rise axis:
1. Whether the working environment of the key bar type gas rising shaft equipment meets the working conditions of the PLC. Whether the electrical cabinet, console, and other components are installed in direct sunlight.
2. Whether there is strong vibration or other strong electromagnetic interference equipment around the equipment. If so, has the equipment been effectively damped, electromagnetically shielded and protected.
3. Whether the incoming line power supply voltage, frequency, grounding wire and grounding resistance of the key bar type air-up shaft device meet the equipment requirements.
4. Is there enough space for maintenance around the equipment?

Technique parameter

The inflatable sleeve (also known as the expansion joint sleeve, the 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, the outer ring and the hub. A huge tightening force is generated to achieve a keyless connection between the machine and the shaft.
When the load is applied, the combined pressure of the expansion sleeve and the machine member and the shaft and the accompanying friction force transmit the torque, the axial force or a composite load of the two.
The expansion sleeve connection has the following advantages: high centering accuracy; convenient installation/adjustment/disassembly; high strength, stable and reliable coupling; protection against damage during overload, especially for heavy loads.
Hydraulic expansion sleeve The main working principle of the expansion sleeve is to press the bolt piston to press the grease in the expansion sleeve to achieve the corresponding working purpose. The expansion sleeve has a large transmission torque and has a large effect. The role of high dynamic balance.
The single cone air expansion sleeve achieves the purpose of work by adjusting the axial displacement of the cone surface, and the air expansion sleeve has the characteristics of convenient disassembly and assembly and high transmission torque.

With the innovation and improvement of the mechanical equipment technology of the inflatable shaft, the application of the air-expansion shaft is more widely used in various industries. First, take the paper slitting machine. The inflation shaft is an important component of the paper slitting machine. There are important applications in the paper slitting machine, which can be used for slitting equipment with high quality requirements and fast speed. Everyday use the slitting machine to increase the shaft and pay attention to the maintenance work to avoid the failure of the expansion shaft.
The following Tianchuang Machinery and everyone share the daily maintenance points of the air-expansion shaft of the slitting machine:
1, neat
The tools, workpieces and accessories are placed neatly; the safety protection devices are complete; the line pipes are complete.
2, do a good job of cleaning
Clean the inside and outside of the equipment; all sliding surfaces and screws, gears, racks, etc. are free of oil and dirt; no leakage, no leakage, no leakage, no leakage; cleaning of the chips.
3, regular lubrication
Oil on time, oil quality, oil quality meets the requirements; oil pot, oil gun, oil cup, linoleum, oil line clean and complete, oil mark is bright, oil circuit is smooth.
4, correct operation, safe use
Implement the system of fixed and fixed shifts; be familiar with the structure of the equipment and comply with the operating procedures, use the equipment reasonably, carefully maintain the equipment, and prevent accidents.
