Week 8 Worm Gear Challenge
Aim:
To perform a transient structural analysis on a worm gear assembly.
Objective:
We will have to 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.
Procedure:
At first we will be importing the geometry model into ANSYS-WORKBENCH and then we will cut the gear alone into half in Space-claim. The final geometry model on which the analysis will be performed is shown in the image below.

Now, we will be providing Connections such as Contacts and Joints for the case setup model and then set boundary conditions for the model. First, we will be providing Contact Connections as Frictionless between the Worm and Gear as shown in the image below by selecting required tooth on both the bodies.

will be providing Revolute Joint Connections the Ground to Worm as shown in the image below by selecting the required

RESULTS
TOTAL DEFORMATION

STRAIN

STRESS

From the above result it can be seen that maximum stress and strain is developed in the tooth face, as teeths are in contact with the worm gear teeth. Maximum deformation is also at the tooth face as there is continous application of load.
