Link 1, rotating about fixed axis A, is connected by a two-motion kinematic pair to link 2. This pair consists of two spherical surfaces a and b which contact spherical socket d and flat surface f of link 2. Link 3, rotating about fixed axis B, is connected by a two-motion kinematic pair to link 2. This pair consists of two spherical surfaces e and g which contact internal cylindrical surface h and flat surface k of link 2. The mechanism transmits rotation between any two arbitrarily located axes A and B.
