Week 8 Worm Gear Challenge

OBJECTIVE:

• To set up the Worm Gear model for Transient Structural analysis

Steps:

Import Geometry:-

• Import the geometry and cut half of the gear to avoid the node limits error for academic version

Define Contact:-

• Rename the parts to our convinience
• Let the material be default one
• Define the contact between parts properly
• Select the gear faces upto its end

Mesh:-

• Mesh the model with default size, make sure the nodes within the limit
• Adaptive sizing =No
  Smoothing=Medium
  

Define Joint:-

• Define Revolute joint of body to ground type for Gear
• Define Revolute Joint of body to ground type for Worm

Analysis Setting:-

• Use Required number of steps so that the worm is covering the gear till its cut portion
  
• Use the revolute joint of worm for the rotation in gradual manner

RESULTS and CONCLUSION:

• Total Deformation=31.44mm
  
  
  
• Equivalent Strain=0.0058089 mm/mm
  
  
  
• Equivalent Stress=1010.2 Mpa
  
• From the above stress graph we can see there is same kind of stress generated for every 360 degree roatation
• Raise and fall in the graph is taking place for every full rotation
