OGIVAL SHAPE BICYCLE FOR TRANSFORMING LINEAR MOVEMENT AT CONSTANT SPEED OF A BIKE CHAIN IN VARIABLE CIRCULAR MOVEMENT OF THE CRANKSHAFT OF THE CRANKSHAFT.

摘要

The plate has two circular arcs rotating around an axis of common cords to regularly vary speed of rotation of a crank on which the common cords are fixed by driving chains at constant speed, where the plate is fixed at the crank of the bicycle by positioning the crank at 108 degrees from a largest axis of the plate. Teeth turn on a different radius to produce progressive and digressive rotation speed.
