General constitution
Tree couplings - Elastic couplings

Couplings are generally made up of three functional parts, plus a protective housing if required (figure 9).

The flanges (or sleeves) 1 and 2 (figure 9) transform a relative angular position error into a displacement (by moving active zones away from the axis of rotation); they are completely connected to the shafts (no relative movement possible).

The elastic elements 3 (figure 9) support the deformations. They ensure deformation of the assembly, torsional rigidity and absorb energy during relative movements of the flanges (through internal...
