Ratchet Mechanism ProDynami 1374 demonstrates how ratchets limit rotary or linear motion to only one direction. This Ratchet Mechanism is composed of a round gear (or linear rack), a pawl, and a base, with tooth geometry featuring a ramp and sharp drop off to restrict reverse motion. The compact design needs only a small vertical wall to block movement in one direction. It is fitted on a Bakelite base board with rubber feet and is movable and easy to use.

Key Features
Construction and Design
The Ratchet Mechanism ProDynami 1374 is composed of three main parts: a round gear (or a linear rack), a pawl (also called a "click"), and a base (or mount). The geometry of the gear or rack is designed with a ramp feature on one side of the tooth leading to a sharp drop off. This geometry restricts motion of the pawl when the linear or rotational direction is reversed. Most ratchet mechanisms are not very large, as only a small vertical wall is needed to prevent motion in one direction. The mechanism is fitted on a Bakelite base board with rubber feet. The apparatus is movable and very easy to use. This Ratchet Mechanism gives detailed information on the working of ratchet-based motion control.
Scope of Delivery
Q: What is the Ratchet Mechanism ProDynami 1374 used for?
A: It demonstrates how a ratchet mechanism transmits intermittent rotary motion or permits a shaft to rotate in one direction but not the opposite, and explains the working of ratchet-based motion limiting.
Q: What are the main components of the ratchet mechanism?
A: A round gear (or a linear rack), a pawl (also called a "click"), and a base (or mount).
Q: How does the ratchet restrict reverse motion?
A: The gear or rack geometry has a ramp feature on one side of the tooth leading to a sharp drop off, which restricts pawl motion when the direction is reversed.
Q: What is the base of the apparatus made of?
A: The mechanism is fitted on a Bakelite base board with rubber feet.
Q: What does the scope of delivery include?
A: 1 experimental unit and 1 instruction manual.
