Week 8 Worm Gear Challenge

REPORT

WORM GEAR

OBJECTIVE

To perform transient structural analysis on a worm gear assembly.

PROCEDURE

Opened the model in space claim GUI.

Cut the gear in half for convenience.

Opened the model in mechanical GUI.

For contacts, added some more tooths in gear as target bodies and made it as frictionless.

For mesh, set the adaptive sizing to yes and smoothing to medium. A 3mm mesh is given,

A body to ground- revolute joint is applied for both gear and worm.

ANALYSIS SETTING

Simulation is set to be run through 15 steps and setting are shown below,

For step 1

For step 2-15All other settings are same as step 1.

Joint load is applied to the worm. The worm is rotated to 750 degrees.

RESULTS

CONCLUSION

The equivalent stress of the worm gear was found to be maximum of 1588.7 MPa.

The total deformation was found to be maximum of 7.2749 mm

The equivalent elastic strain was found to be maximum of 0.0080977.
