Abstract
In a concentric double axis mechanism (); a driving bevel gear () is placed concentrically with and freely from any interference with an axis-A (), a follower bevel gear () is meshed with the driving bevel gear (), and an axis-B () is concentrically connected and fixed to the follower bevel gear (). Since the driving bevel gear () is driven by the axis-B actuator () that is independent from the axis-A actuator (), the axis-B () can be driven being free from any interference with the axis-A (). The axis-A actuator () does not become a load for the axis-B actuator (), nor does the axis-B actuator () become a load for the axis-A actuator ().
