Week 8 Worm Gear Challenge

Aim : To perform a transient structural analysis on a worm gear assembly.

Objectives :

• Get results for Equivalent stress, Equivalent elastic strain and the total deformation in the model.

Procedure :

• First open the Ansys workbench.
• Go to toolbox select the analysis system and double click on the transient structural.
• Import the geometry into transient analysis.

Model setup :

• Go to geometry rename the components as worm and gear.

Contacts :

• Create frictionless contact between worm and gear by selecting teeth faces.

Joints :

• Create revolute joint for worm and gear.

Meshing :

• Turn off adaptive sizing.
• Generate mesh using element size as 1 mm.

Analysis settings :

Joint load :

• Insert rotation for revolute joint of worm.

Solution :

Create output results for :

• Total deformation for model.
• Equivalent stress for Model.
• Equivalent strain for Model.

Results :

Total deformation :

Equivalent stress :

Equivalent strain :

Conclusion :

• In the above simulation of worm gear assembly we can observe the stress strain and deformation rate for the applied parameters.
• From the simulation results, we can see the regions of Max. Total Deformation, Max. Equivalent Elastic Strain and Max. Equivalent Stress occurring on the gear during the simulation.
