The model with a central spacer "GAS / SG / DBSE-AL", in addi
Ɵ

al for connec
Ɵ
ng transmission drives spaced apart. Is
able (unlike the classic model GAS/SG) to recover, as needed, up to twice the angular misalignment (picture 2) and axial (picture 3) or a high
radial misalignment (picture 1) according to the formula:
Where:
K

[mm]
N

It is possible to determine also the
posi
Ɵ
oning error by the torsion angle
according to the formula:
In case of GAS/SG/DBSE-AL the total
torsional rigidity of the coupling is
expressed by the formula:
Where:
