DESIGN AND ANALYSIS OF DIFFERENTIAL GEAR BOX IN AUTOMOBILES PART 2


3. MODELING AND ANALYSIS
3.1. Modeling details
To determine the structural analysis on the differential gear box. First, we have to create a model
of differential gear box in modeling software’s. We have the assembly of differential gear box in
SOLIDWORKS.
3.2. Build Geometry
Construct a three-dimensional representation of the bevel gears in SOLIDWORKS. The assembly
consists of 2 side gears, 2 ring gears and on sun gear. After doing the assembly in solidworks. Save
the file in. IGES format continuing the further work in ANSYS Mechanical.
4. DESIGN OF DIFFERENTIAL GEAR BOX
represents the modeling of first side gear in solidworks. It is creaeted by drawing
the bevel gear profile from prerequisites and removing the faces of bevel gear tooth for 45 deg mating of
other gears for assembly.and adding an extruded stub axles rods to it.
It is the second bevel side gear.This figure represents the modeling of second side gear in
solidworks. It is creaeted by drawing the bevel gear profile from prerequisites and removing the faces of
bevel gear tooth for 45 deg mating of other gears for assembly.and adding an extrude stub axles to it.
This figure represents the modeling of ring gear in solidworks. It is creaeted by drawing the
bevel gear profile from prerequisites and removing the faces of bevel gear tooth for 45 deg mating of
other gears for assembly.and adding an xtrude stub axles to it. The ring rotates while the vehicle is taking
a turn. It rotates in it’s own axis.
This figure represents the modeling of sun gear in solidworks. It is creaeted by drawing the
bevel gear profile from prerequisites and removing the faces of bevel gear tooth for 45 deg mating of
other gears for assembly.and adding an extruded sun gear plates for the fixing of two side and two ring
gears.The sun gears carry the torque that is coming from the engine .
5.CONCLUSION
In this project, we have taken the frictional contact between the mating gears as 0.2 to see does the
frictional contact the effect the load or not. From, the above results and graphs we found that both
grey cast iron and aluminium alloy are preferable for performing the application of differential
gearbox in automobiles. But, when it comes to weight for light utility vehicles Aluminium Alloy
is preferred.
