ABSTRACT:
A speed control device characterized by a reference speed shaft spatially related to a heavy duty shaft, a drive train for driving the reference speed shaft at a constant angular velocity, a drive train for driving the heavy duty shaft at a variable angular velocity and a speed control assembly for continuously comparing the angular velocity of the heavy duty shaft with the angular velocity of the reference speed shaft, and a brake assembly connected to the heavy duty shaft adapted to respond to errors in the angular velocity of the heavy duty shaft for reducing the angular velocity of the heavy duty shaft to that of the reference speed shaft.
