The length of the bolt can be determined according to the total thickness of the flange plate and diaphragm group of the two halves of the coupling. The Steel Laminae Coupling is applied to the high-speed transmission shafting after dynamic balancing in the shafting transmission with corrosive medium working conditions. The main feature of the Steel Laminae Coupling is to compensate the relative displacement of the two shafts connected by the elastic deformation of the diaphragm. When the shaft center deviation exceeds the allowable value during installation, the Steel Laminae Coupling may be deformed, resulting in damage or shortened service life. When multiple deviations occur at the same time, the corresponding allowable value shall be reduced by half. After installation, protective cover and other devices shall be installed around the coupling.
The product of Steel Laminae Coupling has edges, which may cause injury during installation. It is recommended to wear labor protection articles such as thick gloves; When the shaft center deviation exceeds the allowable value during installation, the coupling may be deformed, resulting in damage or shortened service life; Allowable shaft center deviation of Steel Laminae Coupling includes radial, angular and axial deviation. Adjust the shaft center deviation during installation to be within the corresponding allowable value. Tighten the screws after inserting the installation shaft, otherwise the coupling will be deformed; When tightening screws, use a torque wrench, and do not use screws other than accessories for installation.
The Steel Laminae Coupling shall be designed to operate continuously in the unit for more than 3 years, and the coupling and shaft shall be able to bear continuous torque during the unit operation; Instantaneous torque will not damage the Steel Laminae Coupling, but will make the connection invalid; When the displacement of the two axes connected to the Steel Laminae Coupling reaches the rated value, it can operate normally and continuously. The spacer sleeve of the coupling with spacer sleeve shall have sufficient length to install and remove the coupling without moving the shaft. The coupling hub and shaft shall adopt interference fit. When measuring the cylindricity tolerance of Steel Laminae Coupling, it should be carried out before the keyway machining.
When the Steel Laminae Coupling is working, the torque is input from the driving flange, transmitted to the metal diaphragm through the active torque transmission bolts arranged along the circumference interval, and then transmitted to the driven flange by the diaphragm through the driven precision bolts for output. The Steel Laminae Coupling realizes the flexible transmission of the coupling through the elastic deformation of the high-strength alloy diaphragm group, and uses the flexibility of the diaphragm to absorb the relative displacement between the input and output shafts; The Steel Laminae Coupling compensates the residual misalignment caused by various factors in the connecting parts of the transmission shaft system, and strengthens the ability of the elastic deformation of the metal sheet to compensate the angular displacement and axial displacement.
