Expansion sleeve connection unique advantages:
1, the use of the expansion of the main parts of the machine manufacturing and installation simple. Installation of the expansion of the shaft and the hole processing is not as high as the requirements of interference fit high precision manufacturing tolerances. When the expansion sleeve is installed, no heating, cooling or pressurizing equipment is needed, and the bolt can be tightened according to the required torque. The utility model has the advantages of convenient adjustment, convenient adjustment of the hub on the shaft to the desired position. The expansion sleeve can also be used to connect the welded parts.
2, the expansion of long life, high strength. The expansion sleeve is driven by friction, and the connecting piece is not provided with a keyway to be weakened, and no relative motion is produced.
3, the expansion of the overload, will lose the role of connection, can protect the equipment from damage.
4, expansion sleeve connection can withstand multiple loads, the structure can be made into a variety of styles. According to the load of the installation, a plurality of expansion sleeves can also be used in series.
5. The expansion sleeve is convenient to disassemble and has good interchangeability. Because the expansion sleeve can be combined with the hub hub with a larger clearance, the bolt can be loosened when disassembling, and the connecting piece can be easily disassembled. When the tension is tight, the contact surface is tight and is not easy to rust, and is convenient to be disassembled.
Expansion sets produced by our company are widely used in textile, packaging, machine tools, metallurgy, machinery and equipment, with good quality and reasonable price, widely praised by users, the expanding production conforms to the JV/T7934-1999 standard.
