Ratchets and pawls are mechanical assemblies that are used to transmit intermittent rotary movement, or to permit a shaft to Pawls For Ratchets Wheel rotate in one direction but not the other. Ratchets and pawls are usually made of:
steel
stainless steel
cast iron
brass
other metal materials
Features
Ratchets are occasionally called ratchet tires because they consist of a rotating gear or rack with angled the teeth. Pawls, which are sometimes misidentified as ratchets, are slim protrusions that rest against a ratchet to restrict its movement. When the ratchet is rotated in one direction, the pawl is raised and moves smoothly between your angled the teeth. When the ratchet’s rotation stops, the pawl rests between the teeth and makes a clicking sound. Ratchets and pawls that permit rotation in only one direction cause the pawl and tooth to clash if the ratchet is definitely turned the contrary way.

Applications
Applications for these single-direction devices include:
turnstiles
spanners
winders
jacks
The action of a ratchet can be either harsh or smooth, based on the configuration of the ratchet teeth and pawl.
