Helix Angle - Wikipedia
In mechanical engineering, a helix angle is the angle between any helix and an axial line on its right, circular cylinder or cone. Common applications are screws , helical gears , and worm gears . The helix angle references the axis of the cylinder, distinguishing it from the lead angle , which references a line perpendicular to the axis. ... Read Article

ONE inch gear. Therefore a 64 pitch gear would have 64 teeth if the gear were 1” in diameter. Similarly an 80 pitch gear would have 80 teeth if that gear were 1” in diameter. It’s that simple. So basically, the higher the pitch number, the smaller / finer the form or shape of the gear tooth becomes. AB Slotsport Gear ratio Chart spur 6t ... View Full Source
