Objective:

To perform a transient structural analysis on a worm gear assembly,

To find out the Equivalent Stress, Equivalent Elastic Strain, and Directional Deformation.

Introduction:

This project is about performing a transient analysis on a worm gear assembly. Worm gear assembly consists of a gear and a worm having their rotation axes in the cross and their teeth in contact, Hence by rotating the worm, the gear will rotate about its axis as well.

Procedure for setup

Open ANSYS>>Drag and drop transient structural model in the project schematic window.

Go to the engineering data to choose the materials (in our case we are working with the default materiel (structural steel)

Go to the model tab

Rename the different as required

Go to connection >> contacts

Make with them frictionless

Set the joint as follows:

Go to tab for the meshing:

For the meshing choose the values as follows:

The following analysis settings are defined for the simulation.

Set the joint load as follows:

Go to solution tab and insert equivalent stress, directional deformation, equivalent elastic strain.

Results

Equivalent Stress

Equivalent Elastic Strain

Directional Deformation

Summary table

	Equivalent Stress (MPa)	Equivalent Elastic Strain (mm/mm)_	Total Deformation (mm)
Maximum	2952.1	0.014942	14.399
Minimum	2.4137e-5	1.5426e-10	2.525

Conclusion

Through this simulation, we notice that the different properties found are varying along the worm and the gear but we retain that the maximums of equivalent stress, equivalent strain and total deformation are respectively 2952.1 MPa, 0.014942 mm/mm, 14.399 mm.
