Link 1, having spherical head a and rotating about fixed axis A, is connected by spherical pair D to link 2. Link 2 has spherical socket b and spherical head c. Link 3, rotating about fixed axis B, is connected by spherical pair C to link 2. Link 3 has spherical socket d. The mechanism transmits rotation between any two arbitrarily located axes A and B.
