What is a ratchet mechanism

Apr 13, 2017

A one-way intermittent motion mechanism consisting of a ratchet and a pawl. It is mainly composed of rocker, Pawl (pawl) and external Ratchet (Externalratchet). The rocker is the movement input component, the ratchet is the moving output component.

When the rocker is counterclockwise, the pawl hinged on the rod inserts the tooth inside the ratchet wheel, making the ratchet wheel at the same time. When the rocker is swinging clockwise, the pawl slips over the tooth of the ratchet, and the ratchet is motionless. In this way, when the rocker is oscillating continuously, the ratchet gets a one-way intermittent rotation.
