    Z12A type expansion joint sleeve

    description:The Z12A type expansion coupling 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.
    Detailed introduction:

    Advantages of Z12A type expansion coupling sleeve:

    1,Z12A type expansion joint sleeveThe expansion sleeve is easy to disassemble and has good interchangeability.Since the expansion sleeve can combine the shaft hub with a larger matching gap, the bolts are loosened when disassembling, and the connected parts can be easily disassembled.When swelling, the contact surface is tightly fitted and not corroded, and it is also easy to disassemble.

    2. When the expansion sleeve is overloaded, it will lose its connection and protect the equipment from damage.

    3. 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.

    4. 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 manufacturing tolerances like 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.

    5. The expansion sleeve relies on friction transmission, there is no keyway weakening to the connected parts, and there is no relative movement, and there will be no wear during work.
