Abstract:
A bidirectional synchronous gearing mechanism includes a first gear with a first and second gear profile and a second gear identical to the first gear and with identical first and second gear profiles. The teeth of the two gears are meshed together and the gears are rotatably secured about their respective central axes. Rotation of one of the gears causes rotation of the other gear in an opposite direction.
