First run Autodesk Inventor.

1. Step 1:

   Then click
   New>Assembly
   

   

2. Step 2:

   Then save it to your working directory.
   

   

3. Step 3:

   .
   

   

4. Step 4:

   Now in Design menu, click Worm Gear
   

   

5. Step 5:

   Following display menu will appear.Enter all the values shown here.
   

   

6. Step 6:

   .
   

   

7. Step 7:

   Re-orient your model to isometric view shown below.
   

   

8. Step 8:

   Right click on "Worm Gear" of side menu and turn on "Flexible" mode.
   

   

9. Step 9:

   Now click
   Assemble>Constrain
   

   

10. Step 10:

    Following display menu will appear. In place constraint menu you can see the

    "Selection" 1 is active.Select "X Axis" as highlighted with green box in the following

    figure.
    

    

11. Step 11:

    In place constraint menu you can see the "Selection" 2 is active.Now select "X Axis"

    as highlighted with green box.
    

    

12. Step 12:

    Then click OK
    

    

13. Step 13:

    In place constraint menu you can see the "Selection" 1 is active.Now select "Center

    Point" as highlighted with green box.
    

    

14. Step 14:

    In place constraint menu you can see the "Selection" 2 is active.Now select "Center

    Point" as highlighted with green box.
    

    

15. Step 15:

    Then click OK
    

    

16. Step 16:

    Right click on XY Palne shown in side menu, and Turn on its "Visibility".
    

    

17. Step 17:

    Again open the Place Constraint menu as shown in following figure and select "XY

    Plane" as highlighted with green box.
    

    

18. Step 18:

    Now Selection 2 of this menu "XY Plane: of Worm Gear as shown in following figure

    with highlighted green box.
    

    

19. Step 19:

    Click OK.
    

    

20. Step 20:

    Next step is to constrain "Worm" with XY Plane of "Worm Gear". Now the tangential

    constraint will be selected as shown in following figure.
    

    

21. Step 21:

    Select "XZ Palne" of Worm as a 1st Selection.
    

    

22. Step 22:

    Now select "XY Palne" as a 2nd Selection.
    

    

23. Step 23:

    All Constraints are done.
    

    

24. Step 24:

    Now Turn off "Visibility" of XY Plane that yoou have turend on in Step 16.
    

    

25. Step 25:

    Collapse all the menus in side menu.
    

    

26. Step 26:

    Now click the arrow as highlighted with green box, and select "Modeling View".
    

    

27. Step 27:

    From Constraints menu, Right click on last constraint shown here, and select

    "Drive Constraint".
    

    

28. Step 28:

    Following display menu will appear. Now Enter start value as "0 degree" and end

    value as "3600 degree" to get 10 revolutions of worm.

    

29. Step 29:

    Now for advanced setting, click the << button and enter amount of value of

    increment as highlighted.
    

    

30. Step 30:

    Click Forward button as highlighted, and enjoy Animation or Dynamic Simulation of

    Worm Drive. :-)
    

    

31. Step 31:

    Here is the Animation.
    

    

32. Step 32:

    Don't Forget to click "It Worked" here. :-)
