What is kinematic link?

Machine is combination different mechanism and mechanism is made by kinematic chain and kinematic chain is made by kinematic links. So that kinematic link is basic element of a machine or basic part of machine. Examples of links are connecting rod use in internal combustion engine, belts, chain, rope, hydraulic oil and many others. There are different types of kinematic links and these are as follows.

A. Rigid links

The link which does not undergo any deformation while transmitting motion is called as rigid link. There is no change in shape and size of link. Link is not elongate while transmitting motion. There are different types of rigid links and these are as follow. Example of rigid link is connecting rod use in internal combustion engine.

1. Binary link

Binary link


The link which is attached at two different points in mechanism is called as binary link. Example of binary link is connecting rod use in internal combustion engine.

2. Ternary link

Ternary link


The link which is attached at three points in mechanism is called as ternary link.

3. Quaternary link

Quaternary link


The link which is attached at four points in mechanism is called as quaternary link.

B. Flexible link

Flexible link


The links which are partly deform (change in shape and size) while transmitting motion or force but it does not affect to transmission of motion or force. Examples of flexible links are belt, chain, rope and spring.

C. Fluid link

Fluid link


The link in which fluid is used to transmit motion is called as fluid link. In which fluid is stored in a specific hollow shape container and by compression this fluid at one point it transfer motion to another point. In this way fluid links are work. Examples of fluid links used in machines are fluid link used in hydraulic press, lift, jacks and brakes use in automobile.
