Transient Structural Analysis of Worm Gear assembly using ANSYS workbench

Objective: Perform Transient Structural Analysis of a Worm gear assembly and get results for Equivalent stress, Equivalent elastic strain and the total deformation in the model.

Pre-processing setup:

Geometry:

Connections:

Contacts:

Frictionless contact is created between Worm as contact and Gear as target

Revolute Body-Ground joint for Worm and Gear:

Mesh:

Element size of 1 mm is applied to model

Analysis Settings:

Joint Rotational load :

Load is given to worm to rotate 750 degree

Post processing results:

Total deformation:

Min. value = 0 mm , Max. value = 14.82 mm

Equivalent strain:

Min. value = 2.17e-14 , Max. value = 0.011583

Equivalent stress:

Min. value = 3.61e-9 MPa , Max. value = 2204.1 MPa

Conclusion:

• Total deformation with Min. value = 0 mm, Max. value = 14.82 mm is achieved
• Equivalent strain with Min. value = 2.17e-14, Max. value = 0.011583 is obtain in simulation
• Equivalent stress with Min. value = 3.61e-9 MPa, Max. value = 2204.1 MPa is obtain in simulation
