Principle and application of expansion sleeve

    Expansion sleeve: swelling link sets (the expansion sets), is one of the widely used for components of an advanced base under the heavy load machinery connection, in the round and the link in the axis, it is a kind of keyless connection device on the high strength bolts fastening the containment pressure and friction surface between the production load transmission.

    Principle and Application

    Expansion sleeve is a keyless connection device, its principle and use the high strength tensile bolt action, great holding forcebetween inner ring and outer ring, the shaft and the hub, so as to realize the keyless connection parts and shaft. When subjected to load, composite load transfer by combining pressure expanding sleeve and shaft parts, and accompanied by the friction torque,axial force or two persons. 

Spring Chain Tensioner

    Expanding sleeve connection mainly has the following advantages: the high precision; installation / adjust / convenient disassembly; high strength, stable and reliableconnection; can protect the equipment from damage under overload, especially suitable for heavy load transfer. Widely used in heavy machinery, wind power, packaging machinery, printing machinery, CNC machine tools, automation equipment etc.
