Those mechanisms are useful in order to reduce the angular speed of an actuator and multiply torque to a useful level.
In the field of power transmission systems, STAM developed and patented the NUtating GEARbox, or NUGEAR, an innovative mechanism based on the mathematical concept of nutation, implemented with bevel gears. During its multi-annual activity, the staff of STAM developed several versions of the NUGEAR, in order to maximize its benefits and explore innovative production process to manufacture its components. The company has recently filed a second patent covering an optimized setup of the gearbox. Also, several research projects led to new developments of the system.
