Blobloing sleeve is widely used in the international heavy load under mechanical joint is an advanced basic component, in the junction of wheels and shafts, it is by tightening high-strength bolts to make the pressure and friction between the containing surface to achieve load transfer of a keyless joint device.
1. The use of flat sleeves to make the main parts manufacturing and installation simple. The shafts and holes for the expansion sleeve are not processed as high-precision manufacturing tolerances as the over-profit fit. The flat sleeve is installed without heating, cooling or pressurizing the equipment, just tighten the bolts as required. The adjustment is convenient, and the hub can be easily adjusted to the desired position on the shaft. Flats can also be used to bond parts with poor welding.
2. The long service life and high strength of the flat sleeve. The bloating sleeve relies on friction altogether, no keyway weakening of the jointed part, and no relative movement, and no wear will occur in the work.
3. When the flat sleeve is overloaded, it will lose its coupling effect and can protect the equipment from damage.
4. The bulging sleeve joint can withstand multiple loads, and its structure can be made into a variety of styles. Depending on the size of the installation load, it can also be used in series with multiple flat sleeves.
5. The flat sleeve is easy to remove and has good interchangeability. Since the bulging sleeve can combine the hub of the larger mating gap, the bolt will be loosened when removed, making the joint easily removed. When swelling tight, the contact surface closely fits not easy to rust, but also easy to open.
