MME Geneva Stop Mechanism
The Geneva Stop Mechanism, "MME", designed by EDIBON, is a mechanism that transforms continuous circular motion into intermittent motion.
The Geneva Stop Mechanism, "MME", designed by EDIBON, 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 aluminum 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.
Exercises and guided practices
GUIDED PRACTICAL EXERCISES INCLUDED IN THE MANUAL
- Demonstrating the action of a Geneva mechanism during the indexing and dwell periods.
- Plotting the relationship between the angular displacement of the input crank and the output Geneva wheel during the indexing period.
- Determining the velocity and acceleration of the Geneva wheel by graphical differentiation.
- Comparing the values obtained by the equations of motion or the use of velocity and acceleration diagrams.
