A gearing system includes a pair of gear support plates arranged to rotate about parallel but offset axes with the plates extending parallel to each other in parallel radially extending plates. Each plate includes axially extending teeth in the form of sections of lune shaped elements having concave and convex opposed surfaces. The teeth are interdigited axially such that various pairs of interdigited teeth will be in cooperating surface contact. Rotation of each support plate about its own axis causes the teeth to orbit relative to each other and engage in a driving relationship in a smooth manner, with the convex portion of certain teeth engaging smoothly with the concave portion of adjacent teeth. The gearing system provides a 1:1 speed ratio and has application as an Oldham coupling or synchronizer for a scroll fluid device.
