Define ‘Gear Train’. State its purpose and types of gear train.
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 :
A belt is required to transmit 10 kW from a motor running at 600 rpm.........
Construct a cam profile with knife edge follower having an offset of 10 mm........
In reciprocating engine the crank is 250 mm long and connecting rod is 1000 mm long. ..........
