Week 8 Worm Gear Challenge

WORM GEAR CHALLENGE

OBJECTIVES

In this challenge, we have to perform a transient structural analysis on a worm gear assembly. For the academic version, you need to cut the gear by half so as to bring the model within limits. For the challenge, you 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. we can use a finer mesh while performing the challenge and submit a well formatted report with appropriate images.

PROCEDURE

• First, we have to input the engineering materials with required properties or else by creating with required properties.

• Then we have to import our model into ansys, import the model and open it in space claim and cut the model into half so that the academic version support.

• Then assign required connections in this assignment we will use frictionless contact between the components and give revolute joint for Gear and worm gear.

• Then mesh the component with required mesh size in this assignment we will use
  • Mesh – 4mm
  • Nodes – 10161
  • Elements – 4954

• Analysis setting then assign revolute joint load.

• Then give the required solution parameters then solve.

RESULTS

Total Deformation

Equivalent stress

Equivalent strain

Contact pressure

Conclusion

From the above stimulation the transient analysis of worm gear is done with required parameters and result is obtained.
