Air Collet Chuck

The air collet chuck (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 precision in alignment; easy to install/adjust/disassemble; high strength and stable and reliable connection;

Protects the device from damage during overloading, 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...

Technique parameter

Characteristics of the inflatable sleeve: The inflation sleeve is shortly inflated, and the expansion and placement of the inflatable sleeve and the paper tube can be completed in 3 seconds to complete the inflation and deflation, and it is not necessary to separate the sides of the shaft end. Any part can also be tightly engaged with the paper tube.

The paper tube is simply placed: in the action of inflation and deflation, the paper tube can be moved and fixed at any position on the shaft surface.
The expansion sleeve has a large load capacity: the size and length of the shaft diameter can be determined according to the actual needs of the customer, and the high-hardness steel is used to increase the bearing capacity.

Inflatable shaft fittings are economically efficient: the shaft is designed for special functions and is used for all paper tubes of thick, thin, wide and narrow.
Simple maintenance and long service life: The gas rise shaft is a single part, and each part in the structure has fixed specifications, which can be used interchangeably, making it easy to maintain.

Application

Installation of the inflatable sleeve:
1. The first step we should put three bolts in the screw hole of the flange during installation.
2, the second step we have to open the inner sleeve of the expansion sleeve and the jacket
3, the third step and then put our expansion sleeve into a certain position, and then fix it
4. The fourth step of tightening is that each bolt is only screwed to 1/4 of the rated torque at a time (note: the tight sequence is bounded by the slit and symmetrically tightened)
5, through the above four steps, we can install the expansion sleeve
6. Finally, the top hole screw must be removed. The top hole screw is easy to disassemble and install, and it does not work.
Then in our daily life, our inflatable sleeves should pay attention to those! Although the inflatable sleeve is very convenient, there is generally no boundary. However, in general, our expansion sleeves also need to pay attention to the following. Let's talk about what the general inflation sleeve should pay attention to:
1. The expansion sleeve should pay attention to the cleanness of the expansion sleeve during installation, and do not find any pollution.
2, under normal circumstances, do not understand the expansion of the friends may use, MoS2 oil is not right, it is a big mistake, this is best not to use.
3. If the working environment of the expansion sleeve is relatively poor, such as long-term exposure, we must apply anti-rust oil on the front end before the expansion sleeve.
4, quite can also choose the expansion sleeve with good rust resistance, which can solve this problem.
I believe that through the above understanding of the expansion sleeve, we must have a deeper understanding of the expansion sleeve.
