Week 8 Worm Gear Challenge
Worm Gear
Aim
To model a worm gear system and determine strains and stresses
Procedure
- Start a new transient structural model in ansys and import the model
- Open the model in space claim and cut the gear in half so as to meet the academic node and element limits

- Open this model in ansys mechanical.
- Define a frictionless contact as shown

- Define the joints as shown (make sure they are aligned appropriately)

- Mesh the model with 2mm length.

- Define the rotation around Z axis for the joint

Analysis Settings
Set the analysis settings as shown.

(set all the output controls to yes)
Set your output blocks as shown
