Description

Technical Field

[0002] The expansion sleeve is also called the locking coupling plate, or expansion sleeve for short. It is a new and advanced mechanical basic part in modern times. The use of expansion sleeves makes the manufacturing and installation of host parts simpler. The processing of the shaft and hole for installing the expansion sleeve does not require high-precision manufacturing tolerances like interference fit. No heating, cooling or pressurizing equipment is required when installing the expansion sleeve. Only the bolts need to be tightened according to the required torque. It is easy to adjust and can easily adjust the hub to the desired position on the shaft. The expansion sleeve can also be used to connect parts with poor weldability.

[0003] The expansion sleeve connection can withstand multiple loads, and its structure can be made into various styles. According to the size of the installation load, multiple expansion sleeves can be used in series. The expansion sleeve has a long service life and high strength. The expansion sleeve relies on friction transmission, and there is no keyway weakening on the connected parts, and there is no relative movement, and no wear will occur during operation. The current tensioning sleeve is more troublesome to disassemble, and requires the use of multiple tools for coordinated disassembly, which wastes the staff's time and reduces the staff's work efficiency. For this reason, we propose a quick-release tensioning sleeve to solve the above problems. Utility Model Content
