The great use of disc coupling, in recent years, shows that its ability to offset well suited to the needs of most applications, even for high speed and great powers.
Good power-to-weight ratio, which is required in low load uses suspended and high-speed machines, makes it also suitable for normal installations: the product’s versatility makes it adaptable to a wide range of operating conditions.
The disc coupling primary component is the collection of lamlle, and conductive screws and screws have conducted on a common diameter.
The gills are working on the principle of direct shot between conductive and screw screw duct and transmit the torque evenly: this operating principle produces traction of a lamella, which transmits the torque due to the pulling force that occurs between the conductive screws and screws.
Flexibility, which is obtained in free space between nearby screws will vary in extent of the cube of the length of the free space itself.
Leaf discs couplings are not only chosen in consideration of axial thrust, but more frequently based on the offset allowed being thrust generated normally absorbed by the motor bearings.
The axial thrust instead in a toothed coupling is given only by the load on the teeth and the coefficient of friction between the same and has nothing to do with the elastic properties of materials.
This boost, whose presence is often not taken into account in the couplings can be the major cause of failures in broadcasting with helical gear couplings)
The most common cause of failures in a disc coupling is torsional stress of lamellas close to their anchor points; It is therefore important that the same working always within the limits of variable solicitations allowed.
The stresses caused by the torque and the pure axial deviation can be considered constant stress, those caused by angular misalignment are variables.
