A coupling is a mechanical component used to transmit torque and angle. Each model has its own characteristics, please choose the most suitable model for your needs.
According to the model and technical parameters of the driving machine, the model and technical parameters of the driven machine, the installation and transmission system diagram of the coupling, the technical parameters of the installation, the technical parameters of the coupling and the working environment of the coupling, comprehensively purchase the required coupling.
Fixing method of coupling
There are five ways to fix the shaft of coupling: fastening bolt type, clamping type, separating type, separating type and keyway type.
Please select the appropriate coupling according to your requirements. Tightening bolts or hexagon countersunk head bolts should be properly tightened with a screwdriver or torque wrench. Please refer to the product dimension table for tightening torque. The method of fixing the shaft center of the coupling and the adjustment of the deviation of the coupling.
The coupling can transmit torque and angle to absorb the installation deviation of the shaft. When the installation deviation exceeds the allowable value, vibration may occur or the life of the coupling may be shortened. Therefore, it is necessary to ensure that the deviation is properly adjusted. There are three kinds of shaft deviation, radial deviation, angular deviation and axial deviation. Please adjust the deviation to make it lower than the allowable value listed in the technical parameter table of each product provided by the product center. The allowable value of the maximum deviation of the product refers to the situation that there is only one deviation. When two or more deviations exist at the same time, the allowable value should be less than 1 / 2 of the maximum deviation in each technical parameter table. The deviation not only occurs in equipment assembly, but also may be caused by vibration, thermal expansion and bearing wear in operation. Therefore, it is recommended to adjust the axial deviation to less than 1 / 3 of the maximum value.
