The expansion coupling sleeve (referred to as the expansion sleeve) is an advanced basic component widely used in the world today for mechanical connection under heavy loads. In the connection of wheels and shafts, it is a keyless connection device that achieves load transmission by tightening high-strength bolts to generate pressure and friction between the bearing surfaces.
The expansion sleeve connection mainly has the following advantages: high alignment accuracy; Convenient for installation/adjustment/disassembly; High strength, stable and reliable connection; It can protect the equipment from damage when overloaded, especially suitable for transmitting heavy loads. It is widely applied in heavy machinery, wind power generation, packaging machinery, printing machinery, CNC machine tools, automation equipment and other fields.
