The advantages of the expansion sleeve

    1.Using the expanding sleeve so that the host parts manufacturingand installation are simple. Processing unlike mounting expanding sleeve shaft and hole interference that require high precisionmanufacturing tolerances. Expanding sleeve arranged withoutheating, cooling or compression equipment, the bolt tightening torque requirements according to. And convenient adjustment, the hub on the shaft can be conveniently adjusted to the required position. Expanding sleeve and can also be used to connect the poor weldability parts.

    2.The expansion sleeve of long service life, high strength.Expanding sleeve friction drive, the connecting piece no keywayweakened, no relative motion, the work will not produce wear.

    3.The expansion sets in overload, will lose the connection function,can protect the equipment from damage. 

     4,.The expansion sleeveconnection can withstand multiple load, its structure can be made into a variety of patterns. According to the installation load size,can also be multiple expansion sets used in series.

    5.The expanding sleeve and convenient disassembly, and has good interchangeability. Because of the large expansion sleevehub clearance together, removing the bolt loosen, can be easily disassembled piece. Expansion, the contact surface is close billionjoint does not rust, also easy to disassemble.
