Latest Patents
Randall L Sparks holds a patent for an "Angular drive intermittent motion mechanism." This invention provides an intermittent drive mechanism that allows for the intermittent driving of an output shaft with an input shaft. The axes of these shafts intersect at an angle, creating a complex yet efficient system. The driving element on the input shaft couples with a driven element on the output shaft through pairs of corresponding accelerating and decelerating pin and slot combinations. These engage intermittently at the surface of an imaginary sphere centered at the intersection point of the shafts. The design includes embodiments both with and without intermittent driving gears, ensuring that the output shaft maintains a constant maximum velocity through a predetermined arc. The slots are curved, preferably in circular arcs, optimizing acceleration and the rate of change of acceleration, particularly as the output shaft approaches and leaves the point of maximum angular velocity. The invention aims to minimize jerk and maximize efficiency in mechanical motion.
