Product details:
Z3 tightening sleeve principle and application
Lhe swelling sets is a keyless coupling device, the principle and purpose is through the effect of high strength bolt tension, between inner ring and the shaft, the outer ring between the wheel and a huge hug tight force, in order to realize the parts with keyless connection of shaft. When the load is under load, the combined load of the torque, axial force or both of the friction force and the combined load of the machine parts and the shaft is combined with the friction force. The expansion sleeve joint has the following advantages: high accuracy; Easy to install/adjust/remove; High strength, stable and reliable connection; It can protect the equipment from damage when overloaded, especially for heavy load. It is widely used in heavy machinery, wind power, packaging machinery, printing machinery, CNC machine tools, automation equipment and other fields.
