Industrial expansion sleeve


Industrial expansion sleeve (referred to as expansion sleeve) is an advanced basic component widely used for mechanical connection under heavy loads in the world today. In the connection of wheel and shaft, it is produced by tightening high-strength bolts to make the containment surface. A keyless coupling device that realizes load transmission by pressure and friction.


The expansion sleeve is a keyless coupling device. Its principle and purpose are to generate huge holding force between the inner ring and the shaft, and between the outer ring and the hub through the action of high-strength tension bolts to realize the mechanism and the shaft The keyless connection.When under load, torque, axial force or the combined load of the two are transmitted by the combined pressure of the expansion sleeve, the machine part and the shaft and the accompanying friction force.The expansion sleeve connection mainly has the following advantages: high centering accuracy; convenient installation/adjustment/disassembly; high strength, stable and reliable connection; it can protect the equipment from damage when overloaded, especially suitable for transferring heavy loads.It is widely used in heavy machinery, wind power generation, packaging machinery, printing machinery, CNC machine tools, automation equipment and other fields.
