Making a helical gear in AutoCAD: Advanced Tutorial

In this tutorial, you will learn How to Making a helical gear in AutoCAD. This is on categories advanced tutorial. You can learn tutorial step by step and more easly. so let us start. 

 

1. Step 1

   Start AutoCAD.
   
   

2. Step 2

   Make a circle of 35mm radius at center.
   
   

3. Step 3

   Make another circle of 50mm concentric to previous one.
   
   

4. Step 4

   Make two arcs like this one for cutting teeth.
   
   

5. Step 5

   Trim down the circles. Now enter PEDIT command.
   
   

6. Step 6

   Right click on the screen and select multiple.
   
   

7. Step 7

   Select all arcs.
   
   

8. Step 8

   Press enter and keep the input Y and press enter.
   
   

9. Step 9

   Now click on the join.
   
   

10. Step 10

    Press Enter.
    
    

11. Step 11

    Now we can see that it has become a polyline.
    
    

12. Step 12

    Enter helix command.
    
    

13. Step 13

    Enter the radius value of (0,35). Any other value will distort the sweep. Keep the default value for the upper radius. Press Enter.
    
    

14. Step 14

    Now select turns and enter a value of 0.15.
    
    

15. Step 15

    Now enter a height of 50mm. We have helix path generated which will later be used for cutting the teeth.
    
    

16. Step 16

    Create a circle of 50mm with origin as center.
    
    

17. Step 17

    Extrude it by 25mm.
    
    

18. Step 18

    Enter SWEEP command.
    
    

19. Step 19

    Select the polyline to sweep and press enter.
    
    

20. Step 20

    Right click and select alignment.
    
    

21. Step 21

    Select No.
    
    

22. Step 22

    Again right click and select twist.
    
    

23. Step 23

    Keep the default values and press enter. Now select the helix as the sweep path.
    
    

24. Step 24

    We have one cut body generated.
    
    

25. Step 25

    Now enter array command.
    
    

26. Step 26

    Select array type polar and enter origin as center for array. Click select object and select the sweep. Now enter the no. of items be 10. Click OK.
    
    

27. Step 27

    Subtract the arrayed sweeps from the cylindrical body and we have the helical gear created.
    
     
    
    Now the tutorial How to Making a helical gear in AutoCAD has been finished. If you need any tutorial to improve your skill in autocad please visit other tutorial on this blog. Ok thanks for coming.
