Customized Transmission Gears-Assembled Ratchet Wheel 16 Module 84 Teeth

1) Description of ratchet Gear

A ratchet gear is a specialized gear type that may only turn in one direction. Most ratchet gears have teeth

that are round on one side and flat on the other. The section of the ratchet that interacts with the gear,

called a pawl, will slide over the rounded side, but will get caught on the flat side. This one-directional spin

makes ratchet gears well-suited for tasks that require discrete points, such as clicks on a dial. Unlike many

one-directional gear systems, ratchets do allow a small amount of backward motion; this makes them better

for non-powered applications where slippage won’t cause damage.
