Excellent video. The best, technically correct video, I have come across. Most use arcs for involute, which is incorrect. A suggestion: For creating the involute, one may use a coordinate system that is angled so as to eliminate the involute arc manipulation. A Request: Please create a video for spiral beval gear too.
Hi I am glad to note that you are appreciating my efforts. I have Spiral Bevel gear model also. In my spare time I shall create the videos for them also.
Hi I am glad to note that you are appreciating my efforts. I have Spiral Bevel gear model also. In my spare time I shall create the videos for them also.
I get stuck at the same place as many others, between 12:00 - 14:00, however even after reading the answers others got I still struggle to understand how to use the formula. Can anyone help?
I have a problem one. When you rotated this curve in the opposite direction, you rotated it from the relation you wrote: d22 = (360 / (Z1 / cos (delta1)) / 4). What is d22 to you in the formula? i couldn't figure it out and i can't continue modeling gears without copying the curve.
After creating the Notebook table and saving it in the working folder, it is to be "Declared" in the part model. Then all the parameters created in the Notebook are imported into the part model.
Very good Video. It would be great to explain the steps between 12:00 and 14:00min a little bit better, cause I had trouble to recreate this step in my model. But I think now I have understood the step. However I still think my model is still not right. So it would be great if you could share your model.
As I have explained in the video, this step is to create a gear tooth symmetric about the top plane. When we create the initial Involute curve through equation you would notice that the starting point of the curve lies on the top plane. Hence, this needs to be rotated by a certain amount which is determined by the Angle Measurement feature. I can share the model with you through email, However, please note that these models are in Creo 7.0 version now.
@@anandi1974 Thanks for your answer. I figured out how to do it. My problem was, I couldn't figure out how to move a curve by reference and used the wrong Axis for the rotation. However I still would be happy to look into your file. I Will send you my mail-adress via private message.
i actually didn't understand the second rotation of involute curve... can you please explain the process and why we are doing so..... can you please share the prt file of this gear
the very purpose of two rotations is that the first teeth should be symmetric to the Front plane. This is helpful in assembly of Bevel Gears. In the first rotation, we are rotating the curve so that the point of intersection of Involute curve and the pitch circle lies exactly on the Front plane. In the next rotation, the curve is rotated in the opposite direction so that the gap created thus can accommodate the teeth from the mating gear.
"t" is a system parameter which assumes the values from 0 to 1 (generally). However, you have the option to change the boundary limits as per your convenience. The default values of 0 and 1 are used in the current video. And thanks for the kind words!
Thanks a lot for the tutorial. I have modeled the gears exactly according to the video, but it seems that the teeth in my model are too wide and cause a collision. Are the 3D files of this video available so i can compare it to see where i made a mistake?
@@anandi1974 Sir, thank you for this video, its really great. I have followed the video , and made my gears, but same as man said, I have a too wide tooth profile regarding big gear, and I can't have 40 teeth. Could you send me please 3D models, so I can check what am I doing wrong? Thanks in advance!
@@thamaraiselvanarumugam8812 If you got files then could you please share with me? prashantgore18@gmail.com It will be more helpful for me to understand better. Thank you in advance.
This video does not show A LOT of steps. BEWARE. the guys starts fine at the beginning and everything works but at the middle of the video he leaves out vital info. Relations of the second rotation copy of curve are not very clear. d22=(360/Z1/cos(delta1))/4) and p52=Z1... Which dimentions are d22 and p52? Where are they located?
Yes, there is a lot missing. unfortunaltey. Nevertheless, thank you. 3 quarter the way is better than nothing ;) 1. Why did you not show the "crucial things": Past special and how to link measurement feature into the shift of the involute curve. You decently show later that d20 ist the shift variable. If you explain this first most can follow better 2. In the very end you do not show how exactly the revolving and pattering is parametrized. It makes your nice video just incomplete. To complete the pattern a formula to calculate variable P (angle between teeth) is missing. You just showed p52=Z1 and called it a day :) So for variable angle dXX=360/Z1 needs to be added. Cheers
I am sorry I do not have the model in Creo 2.0 version and unfortunately the 3D model created in Creo 3.0 can not be opened with Creo 2.0. In fact I have moved on Creo 5.0 now. Any further video I create would be using Creo 5.0 only.

Rudra Shiva, I have not tried to create a Crown Gear model as of now. Whenever I do, I shall make a video tutorial and upload the same here.
can u send me upload those .prt file and give us link
can you explain how you set up the mechanism? how did you get the teeth to align?

d22 is the angular dimension for the rotation operation. The dimension parameter name could be different in your case.
@@anandi1974 thank you for the explanation
Sir, notebook table and parameter value are how to add in model for making bevel gear?
Please , show this details.

I'm a little confused , is the involute curve rotated about the z axis we created perpendicular to the datum plane?
The involute curve is rotated about the Z axis of CS0 co-ordinate system
It's an excellent video, but can you tell me that which value did you took for "t" in in X and Y for creating teeth in curve.
"t" is a system parameter which assumes the values from 0 to 1 (generally). However, you have the option to change the boundary limits as per your convenience. The default values of 0 and 1 are used in the current video. And thanks for the kind words!

Thank you very much

Hi Ananda kumar
Sorry, but it's time to move to Linux !
I did not get your point. In what way, your comment is relevant to modeling of Bevel gear using Creo software?
Because creo is great software. And many users will it use under Linux.
bad presentation of skills
