Display motion in Helical Gear through Dynamic Simulation

  1. Create a ‘New Assembly’ and save it with the name ‘Helical Gear–Dynamic Simulation’.
  2. Select Place component from the marking menu and place the Helical Gear in the Assembly.
  3. Align the Gear in correct position by using View Cube.
  4. Select the Gear in the Design window, right click and deselect Grounded from the context menu.
  5. At present there are six Degrees of Freedom in Gear and it can be moved in any direction in the Assembly.
  6. Open the visibility of Z Axis of Assembly and Z Axis of Gear from the Browser Bar, and then apply a Mate Constraint between them.
  7. Apply another Mate Constraint between Centre point of the Assembly and Centre point of the Gear.
  8. Now this time only one Degrees of Freedom is left and Gear can be moved only on its Z Axis.
  9. Select Place component from the marking menu and place the Pinion in the Assembly.
  10. Activate the Constraint command and change the constraint type to Flush in the Solution field, select the top face of Pinion and top face of Gear, click apply.
  11. Apply a Mate Constraint between YZ Plane of Gear and YZ Plane of Pinion.
  12. Set the browser from Assembly View to Modeling View using the toggle at the top of the browser.
  13. Open visibility of Pitch Diameter of Gear and Pitch Diameter of Pinion and then apply a Tangent Mate between them.
  14. Create a Work Axis in the Assembly, coincident with the axis of surface of Pitch Diameter of Pinion.
  15. Activate the Work Axis command from the Work Features Panel of Assemble Tab, and then select Through Revolved Face or Feature in the Axis drop down menu.
  16. Select Pitch Diameter of Pinion to create the Work Axis.
  17. In the Quick Access toolbar, click the selection tool dropdown list and choose Select Sketch Features.
  18. Convert this Work Axis to ‘Grounded’.
  19. Activate the Motion Constraint, first select the top face of Pinion and then top face of Gear. In the Ratio input box, enter the value 23/57 and click Ok.
  20. Suppress the Mate:3 Constraint in the Browser.
  21. Once again, check the Degrees of Freedom of gear and pinion in the assembly, this time both the gears are rotating on their own Axis.
  22. Activate the Dynamic Simulation Tool from the Begin Panel of Environments Tab.
  23. Select Insert Joint in the Marking menu.
  24. Select ‘Rolling: Cylinder on Cylinder’ from the drop down menu of Insert Joint dialog box.
  25. Select Rolling constraint option.
  26. First select the Pitch Diameter of Pinion and then the Pitch Diameter of Gear. Click Ok.
  27. Select Revolution:3 joint in the Browser under the Standard Joints folder, right click and select Properties from the context menu.
  28. Click dof 1 (R) tab and select Edit imposed motion button and check the Enable imposed motion option.
  29. Click the arrow to expand the input choices, and click Constant Value.
  30. Enter the value 360.000 deg/s, and click Ok.
  31. In the Images field, enter the value 1000.
  32. Close the visibility of Pitch diameter of Helical Gear and Pinion.
  33. Mesh the teeth of Gear and Pinion manually in front of each other, after Suppressing the Motion Constraint.
  34. Once again Un-suppress the Motion Constraint.
  35. Clear the screen by activating the Clean Screen command.
  36. Click Run in the Simulation Player to display motion in Helical Gear and Pinion.
