## 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

## Difference between a machine and a structure

Before we go through the difference between a machine and a structure, let’s first see what they are. Once we comprehend that, understanding the difference between them will be a cakewalk for us. Machine: A machine typically contains mechanisms that

## 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

A deltoid linkage is a four bar mechanism which consists of two pairs of equal and adjacent links. It is a grashof linkage for which the sum of the lengths of the shortest link and the longest link is equal

## 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

## What is a Kinematic Joint?

A kinematic joint is a connection between two or more links, which allows some motion, or potential motion, between the connected links.  Depending upon the number of links at the joint, a joint can be binary, ternary or quaternary. The
