    name:

    Z8 type expansion joint sleeve

    description:Features of Z8 type expansion coupling sleeve: Z8 type locking coupling disc Z8 type expansion sleeve is suitable for coupling the shaft and the parts on the shaft to transmit torque and axial force.The torque Mt and axial force Ft specified in the standard are calculated according to the corresponding screw tension, and the tightening torque of the screw should reach the required rated value in the technical parameter table.
    Detailed introduction:

    Z8 type expansion joint sleeveFeatures: Z8 type locking coupling disc Z8 type expansion sleeve is suitable for coupling the shaft and the parts on the shaft to transmit torque and axial force.

    Torque moment and axial moment of expansion sleeve

    1 Torque Mt refers to the large theoretical torque when transmitting pure torque, and the axial force Ft refers to the large axial force that can be transmitted when there is no transmission torque.If not only transmitting torque but also transmitting axial force, the synthetic torque Mt1 should be calculated as follows:

    Where:

    Mt1—synthetic torque, KN.m

    Mt —theoretical torque, KN.m

    d —Shaft diameter, m

    p —the axial force to be transmitted,

    KN

    2 Bolt tightening torque MA°

    The torque Mt and axial force Ft specified in the standard are calculated according to the corresponding screw tension, and the tightening torque of the screw should reach the required rated value in the technical parameter table.
