DESIGN AND ANALYSIS OF DIFFERENTIAL GEAR BOX

MECHANICAL ENGINEERING

Differential is an essential part of any four wheeled vehicle. A differential allows wheels of a vehicle to rotate at different speeds. This is necessary when the vehicle turns. The Differential gear is a part for all four wheelers, wheel reserved the power from engine to gear box then by drive shaft to differential gear. Differential innovation was created hundreds of years prior and is viewed as a standout amongst the most astute developments human reasoning has ever delivered the car differential enables a vehicle to turn a corner while shielding the wheels from sliding. In automotive mechanics, gear arrangement that permits power from the engine to be transmitted to a pair of driving wheels, dividing the force equally between them but permitting them to follow paths of different lengths, as when turning a corner or traversing an uneven road. On a straight road the wheels rotate at the same speed; when turning a corner, the outside wheel has farther to go and will turn faster than the inner wheel if unrestrained. The Wheels are taking the force power from the engine by a drive shaft. The wheels that get power and make the vehicle push ahead are known as the drive wheels. The fundamental capacity of the differential rigging is to permit the drive wheels to turn at diversely RPMs while both are getting power from the motor engine, Power from the engine is flowed to the wheels via a drive shaft. The main objective of this paper is to perform mechanical design of differential gear box and analysis of gears in gear box. We have taken grey cast iron and aluminium alloy materials for conducting the analysis. Presently used materials for gears and gears shafts is Cast Iron, Cast Steel. So, in this paper we are checking as the aluminium can be the other material for the differential gear box for light utility vehicles so, we can reduce the weight.
