Item Description

A Geneva mechanism, also known as Maltese cross, produces intermittent motion from continuous circular motion. It is a positive drive mechanism in which the driven wheel is positively moved or locked.

The Geneva wheel contains a number of slots into which the driving crank engages, and the number of slots determines the velocity ratio during periods of motion.

When the Geneva wheel is not being indexed, it is locked by means of a locking plate, whose convex surface mates with the concave surface of the Geneva wheel except during the indexing period.

Sci-tech Geneva Mechanism Model MT 113 has been designed to demonstrate the action of a Geneva drive during the indexing and rest periods.

Sci-tech Geneva Drive Mechanism Model MT 113 is a mechanism that transforms continuous circular motion into intermittent motion. It is a positive drive in which the driven wheel is positively moved or locked.

It is made of aluminium and consists of a rotating drive wheel and a driven wheel with six slots. The drive wheel has a pin that reaches into a slot of the driven wheel, advancing it by one step. The drive wheel also has a raised half-moon blocking disc that locks the driven wheel in position between steps.

The drive wheel and the driven wheel are mounted in two graduated discs, where the angle of both wheels can be measured
