## Spherical Geneva Mechanism

Spherical Geneva mechanism is a type of intermittent motion mechanism. It translates a continuous rotation into intermittent rotary motion. The driver and the driven wheels are on perpendicular shafts. The rotating drive wheel has a pin that reaches into a

## Linear Geneva Mechanism

Linear Geneva mechanism is a type of intermittent motion mechanism. It translates a continuous rotation into intermittent linear motion. The crank (driver) has a pin that reaches into a slot of the slider. The driver wheel has a raised circular

## Grashof’s Law

Consider this four bar mechanism: s = length of the shortest link l = length of the largest link p and q = lengths of the other two links By Grashof law, for at least one link to be capable

## Ratchet and Pawl Mechanism

Ratchet and Pawl mechanism is a type of intermittent motion mechanism. It allows the rotation of the shaft in one direction only and prevents its motion in the other direction. It consists of an arm that pivots about the center

## What is a Mechanism?

What is a mechanism? A mechanism is a combination of a number of bodies assembled in such a way that the motion of one causes constrained and predictable motion to the others. The purpose of mechanism is to transform motion
