Week 1 Spur Gear Challenge
Performed spur gear simulation with 3 material graded mentioned above:
| SPUR Gear Simulation | |||
| Cast Iron | Cast steel | Cast Bronze | |
| Yield Stress (MPa) | 79.81 | 349 | 144 |
| Ultimate Stress (MPa) | 141.4 | 505 | 267 |
| Deformation (mm) | 30 | 30 | 30 |
| Von-mises stresses (MPa) | 311.4 | 326.08 | 311.73 |
| Elastic strain (%) | 0.35258 | 0.16275 | 0.39512 |
| Stress Intensity (MPa) | 322.67 | 341.65 | 330.53 |
From above table, stresses in cast steel are below yield limit within elastic limit. So, cast steel will be ok material for these spur gears with given loading.
Below plots are comparison of CAST IRON, CAST STEEL and CAST BRONZE as below:
