Differentials: Gears and Spline Shafts

2. Objectives
To describe and explain gears and spline shafts with respect to differentials
To further your understanding of a common mechanical system in order to expand your general knowledge as mechanical engineers

3. The Basics of Gears Change the rate of rotation of a machinery shaft
Change the direction of the axis of rotation
Change rotary motion to linear motion

4. Spline Shafts
-Splines transfer the rotary motion of an input to an output through a mechanical connection, or splined shaft

5. Automobile Differential Schematic

6. Degrees of Freedom Differential mechanisms possess two DOF :
Engine power
Frictional kinematic chain between the two wheels and the ground

7. Conclusion Basic understanding of gears and spline shafts
Their relation to differentials
How they deal with power and transmission of power
