Brief DescriptionAn Oldham coupling can transmit rotational motion between two parallel but non-collinear shafts. It uses two linear sliders, arranged at 90 degrees to each other on opposite sides of an intermediate floating element. Because the two connected parts can slide freely along their respective sliders, each slider transmits no force in the direction of sliding. However, when one part rotates, its slider slot rotates with it, and this rotation is directly transferred to the other slider slot. As a result, the other part rotates by exactly the same angle. For this reason, an Oldham coupling maintains consta
