Description of the elastomeric element
The main features that distinguish this elastic element are as follows:
> Good resistance to all common lubricants and hydraulic fluids. > Optimum mechanical properties. > Green element suitable to operate for short periods up to 170 °C.
In accordance to the torque to be transmitted, it is necessary, to take into consideration, the necessary flexibility comparing the misalignments allowed from the kind of coupling selected, with the real ones, seen by the shafts to be connected.
It is important to consider that misalignments, axial, angular and parallel, must be considered paired together, as inversely proportional (one reduces when the other increases). If all types of misalignments occur, it is necessary that the sum in percentage respect to the maximum value doesn’t exceed 100%.
Specific procedures to assemble this coupling are not required.
1) Achieve radial and axial alignment as precisely as possible for maximum absorption of possible misalignments and the long life of the coupling. 2) Having pre-assembled the coupling, insert the external half-hub on one shaft. Check that the external parts of the two shafts don’t exceed the relevant half-hub’s surface (quote “N”) and fix this one to the shaft with its relevant fixing system. 3) Close the second shaft inserting it into the internal half-hub for a quantity not higher than the length of the bore (quote “N”). If the insertion should be difficult, due to an accentuated misalignment, it is advisable to release all the connection pins, this will allow for a higher flexibility between the two half-hubs. 4) After having inserted and fixed the hubs, take away each connection pin, damp them with loctite threadlocker, and reassemble and tighten them carefully in progressive way following a cross sequence. 5) Cover the pins with the protection band, making the holes of the band coincide with the relevant locking spheres.
