Detailed parameters of Z12A type expansion coupling sleeve
Z12A type expansion joint sleeve
 
The Z12 type expansion sleeve is suitable for the connection of the shaft and the parts on the shaft to transmit the combined load of the torque and the axial force.
Z12A type expansion coupling sleeve has many unique advantages:
1 The use of expansion sleeves makes the manufacture and installation of main machine parts simple.The processing of the shaft and hole for installing the expansion sleeve does not require high-precision manufacturing tolerances like the interference fit.There is no need for heating, cooling or pressurizing equipment when installing the expansion sleeve, just tighten the bolts according to the required torque.The adjustment is convenient, and the hub can be conveniently adjusted to the desired position on the shaft.The expansion sleeve can also be used to connect parts with poor weldability.
2 The expansion sleeve has a long service life and high strength.The expansion sleeve relies on friction transmission, there is no keyway weakening to the connected parts, and there is no relative movement, and there is no wear during work.
3 When the expansion sleeve is overloaded, it will lose its connection and protect the equipment from damage.
4 The expansion sleeve connection can bear multiple loads, and its structure can be made into a variety of styles.According to the installation load, multiple expansion sleeves can also be used in series.

5 The expansion sleeve is easy to disassemble and has good interchangeability.Since the expansion sleeve can combine the shaft hub with a larger fit gap, the bolts are loosened when disassembling, so that the connected parts can be easily disassembled.When swelling, the contact surface is tightly fitted and does not rust, and it is also easy to disassemble
