The functions of tensioning sleeve in mining machinery and equipment mainly include the following points:
Transfer torque and axial force:
The expansion sleeve converts the axial force (such as the fastening force of the bolt) into the surface pressure on the inner diameter side and the outer diameter side of the hub hole through the conical surface, so that the shaft and the hub hole are closely attached, and sufficient friction force is generated to transmit the torque and axial force or the composite load of the two.
Simplify parts manufacturing:
The use of expansion sleeve can simplify the manufacturing process of equipment parts, especially suitable for repeated forward rotation and reverse rotation.
High centering accuracy:
The connection of expansion sleeve has high centering accuracy, and it is convenient to install, adjust and disassemble, and it is not necessary to specify the alignment of key and hub in the design stage.
Protect equipment from damage:
In the case of overload, the expansion sleeve will lose its connection function, thus protecting the equipment from damage.
Bear multiple loads:
The expansion sleeve connection can bear multiple loads, and according to the installation load, multiple expansion sleeves can be used in series.
Convenient disassembly and good interchangeability;
The expansion sleeve is easy to disassemble and has good interchangeability. Because the expansion sleeve can combine the shaft and the hole with large fit clearance, the bolt can be loosened when disassembling, so that the connected part can be easily disassembled.
Strong adaptability:
The expansion sleeve can be adjusted in size according to needs to adapt to parts with different diameters, which improves the processing flexibility and reduces the inventory and cost.
Improving machining accuracy and reducing tool wear;
Expanding sleeve can provide better positioning and support, which is helpful to improve the machining accuracy of parts, reduce the wear of tools and prolong the service life of tools.
Reduce vibration:
The expansion sleeve can provide better rigid support, reduce vibration and help improve machining quality.
