CARDAN JOINT Meaning and
Definition
-
A Cardan joint, also known as a universal joint, is a mechanical device that connects two intersecting shafts, allowing transmission of rotary motion between them. It consists of three main elements: two yokes and a cross-shaped component called a spider or trunnion. The yokes are fitted to the ends of the shafts, while the spider is positioned between them. The spider has four arms that are connected to the yokes with bearings.
The primary purpose of a Cardan joint is to transfer rotational motion from one shaft to another even when the two shafts are not aligned with each other. This is achieved by the flexibility of the spider, which can rotate in any direction, accommodating slight misalignments between the shafts while transmitting torque. The angle between the input and output shafts can vary without affecting the smoothness of motion or causing excessive stress on the joint.
Cardan joints are widely used in various applications, such as automotive drive systems, industrial machinery, and power transmission systems. They are particularly advantageous in situations where the shafts need to transmit torque at different angles or when there is a need for a high level of flexibility. However, it should be noted that Cardan joints have limitations in terms of maximum angle capability and vibrations. These limitations should be considered during their design and usage to ensure proper functioning and longevity.

Etymology of CARDAN JOINT
The term "Cardan joint" is named after its Italian inventor, Gerolamo Cardano. Gerolamo Cardano was a Renaissance mathematician, physician, and philosopher who lived from 1501 to 1576. He is best known for his works in mathematics, mechanics, and medical studies.
Cardano's groundbreaking work on mechanical devices and his contributions to the field of engineering led to the development of the "Cardan joint". This joint is a type of universal joint used to transmit rotational motion between two shafts that are at an angle to each other. The Cardan joint allows rotational movement in two axes, allowing the shafts to offset and accommodate misalignment.
The term "Cardan joint" is widely used around the world in reference to this type of universal joint, honoring the Italian mathematician's pioneering work in the field.
