Worm Gear Analysis
AIM:
- To perform transient structural analysis of Worm Gear and evaluate the stress and deformation results.
OBJECTIVES OF THE PROJECT:
- To assign Structural steel for worm and wheel.
- To define the contacts for the worm and worm wheel.
- To define revolute joints.
- To mesh the model.
- To evaluate the stress, deformation and strain in the work piece.
PROCEDURE:
- Case 1 – Structural steel
- OPEN WORKBENCH21 > NEW PROJECT > TRANSIENT STRUCTURAL.
- This will start a new transient structural project.
- Rename the project as Worm wheel.
- Go to ENGINEERING DATA > STRUCTURAL STEEL.
- Then double click on Geometry. This will open the Spaceclaim.
- In Space claim check the model for any dents or irregularities.

- The geometry looks good, exit the Spaceclaim.
- Then double click on Model. This will open Mechanical module.
- Now, rename the geometry as Worm and Wheel.
- Then assign Structural steel to all the parts.

- Then go to CONTACTS > CONTACT > RENAME BASED ON DEFINITION.
- INSERT > CONTACT > CONTACT BODIES > TARGET BODIES > TYPE = FRICTIONLESS.

- CONNECTIONS > INSERT > JOINT > TYPE = BODY-GROUND > TYPE = REVOLUTE > SCOPE = WORM INNER SURFACE.

- CONNECTIONS > INSERT > JOINT > TYPE = BODY-GROUND > TYPE = REVOLUTE > SCOPE = WHEEL INNER FACE.

- This will define the Revolute Joint.
- Now, go to MESH > DEFAULT > GENERATE MESH.

- The mesh will be generated on the model.
- Then go to STATIC STRUCTURAL > ANALYIS SETTINGS > NO OF STEPS = 15 > AUTO TIME STEPPING = ON > CARRY OVER TIME STEP = ON > MINIMUM TIME STEP = 0.2 > MAXIMUM TIME STEP = 0.5 > LARGE DEFLECTION = ON > WEAK SPRINGS = PROGRAM CONTROLLED > OUTPUT CONTROLS = YES.

- Go to STATIC STRUCTURAL > INSERT > JOINT LOAD = REVOLUTE – GROUND TO WORM > TYPE = ROTATION > MAGNITUDE = TABULAR DATA.


- Then, go to SOLUTION > INSERT > STRESS > STRAIN > DEFORMATION.

- This will set the output results.
- Then SOLUTION > SOLVE.
RESULTS:
LEARNING OUTCOMES:
- To setup transient structural analysis
- To assign material from the material library.
- To define joint loads.
- To define rotation for Worm and Wheel.
- To deploy mesh on the geometry.
- To define output results.
CONCLUSION:
- By performing this project we conclude that the Transient analysis of Worm Wheel is performed and the stress, strain and deformation results are obtained.
