EF-3.3 – Mechanisms – Additional Mechanisms

The EF-3.3 Additional Mechanisms experiments kit provides students with an introduction to conversion of motion using a Ratchet and Geneva mechanism.

Description

The Engineering Fundamentals range enables students to gain an understanding of the principles of engineering by the process of learning via experimentation.

The EF-3.3 Additional Mechanisms experiments kit provides students with an introduction to conversion of motion using a Ratchet and Geneva mechanism.

The Geneva mechanism is a gear mechanism that translates a continuous rotational movement into intermittent indexed rotary motion, with accurately locked location of the driving component. Such mechanisms are frequently used in mechanical watches, film movie projectors and movie cameras.

A Ratchet mechanism allows for continuous linear or rotary motion in one direction while preventing movement in the opposing direction. Such mechanisms are widely used in machinery and tooling such as jacks, hoists, and socket wrenches.
