Week 8 Worm Gear Challenge

Report week 8 Worm Gear Challenge

Aim: Perform a transient structural analysis on a worm gear assembly. Cut the gear by half so as to bring the model within limits. Rotate the worm so as to get to almost end of the half cut and get results for Equivalent stress, Equivalent elastic strain and the total deformation in the model.

Procudure:

Import geometry: cut a half of worm wheel

Material is structural steel

Contact: frictionless

Joints:

Revolute-body to ground

Mesh:

Analysis setting:

1st step

rest steps

Joint load: 30 step, 50 degree per step

Result:

Total deformation:

Equivalent strain

Equivalent stress

Conclusion

The transient structural analysis on a worm gear was carried out. The maximum total deformation is 14.38mm. The maximum equivalent stress is 992.49 MPa. The maximum equivalent strain is 0.0059. They are developed in the teeth of the worm wheel .
