Latest Patents
Shackelford holds a patent for a differential drive mechanism. This mechanism is especially useful when assembled with a harmonic drive transmission. It provides a desired rotational input to the wave generator of the harmonic drive transmission. The design allows for a wide speed range selection while minimizing component wear, instability, and heat generation problems. This harmonic drive assembly is particularly beneficial in powering a controlled infeed or chill stand in a printing press. It permits precise adjustment of the tension of the continuous paper web moving through such a press. The drive mechanism supplies rotational movement from the input shaft of the harmonic drive transmission to the wave generator tuner shaft. It includes pulley means operatively coupled to the input shaft, an arm assembly mounted for pivotal movement about the tuner shaft, and a positioning mechanism for precisely pivoting the arm assembly as desired. The arm assembly features a variable sheave pulley operatively interconnected with the pulley means and tuner shaft. Pivoting the arm assembly changes the pitch diameter of the variable sheave pulley, which effects a corresponding change in the rotational velocity of the wave generator tuner shaft.
