a) Kinematic link: Each part of a machine, which moves relative to some other part, is known as a kinematic link (or simply link) or element. Kinematic Chain: When the kinematic pairs are coupled in such a way that the last link is joined to the first link to transmit definite motion (i.e. completely or successfully constrained motion), it is called a kinematic chain.
Definition: When two or more gears are made to mesh with each other to transmit power from one shaft to another. Such a combination is called gear train
Purpose: The purpose of the train used is
To obtain correct & required velocity ratio between driver & driven shafts.
To decide upon the relative position of the axes of shafts.
To decide upon amount of power to be transmitted between shafts
Types: Following are the different types of gear trains, depending upon the arrangement of wheels :
