Creo Parametric - Spur Gear Design | Involute Curve

[@kamleshkailasjoshi2620]

THANK YOU SO MUCH SIR, I HAD TRIED THIS BEFOR WATCHING THIS VIDEO , BUT I FAIL EVERY TIME TO MAKE PARAMETRIC GEAR .. BUT JUST BECAUSE OF YOU I LEARN IT FASTER. IN FUTURE AFTER GETTING GOOD SALARY AND INCREMENT I WILL BUY THE MONTHLY SESSION . , LOVE ROM INDIA

[@silentprayers728]

how did you get to the "add additional references" menu at 12:36? Ah, you hold right click.

[@siddhantsaxena2708]

Thanks a Ton for the vedios. I am stuck at 6 degree offset plane used to mirror the involute profile. it defines the tooth thickness and works fine till a perticular size of gears but beyond that it fails. can you please explain you to define that value in simple terms. will be really helpful, Thanks

[@howtoxpert1]

Great, I was looking for a proffessional designing of gear, you did it . Thanks alot.

[@SuperAbc2015]

for some reason my curve keep intersection with each other after mirroring, until I have noticed datum angle on my design supposed to be 6.55 instead of 6, I'm not sure if it because I used a different diameter than what you use or something els

[@jozefnouwen370]

hello, can somebody help me? im stuck @ 11:23. i can not get the rotation form 6°. i Always get a offset.

[@jozefnouwen370]

never mind you have to press control

[@deepakpradhan7168]

11:26 you have to use ctrl + click on axis and then bottom plane to make plane at angle

[@awaisrafeeq01]

Thanks, it was very useful. and kindly describe how we can vary that 6 degree angle according to our design. 11:26

[@CADPLMGuy]

That 6 degree angle is wrong. It should be 4.5 for 20 instances. I’ll cover that in another video. There should be a Relation that the angle of the mirror plane is 360 divided by ( 4 times number of teeth ). I’m learning this as I go along.

[@timbarrett4580]

​@@CADPLMGuy Just for future people in the comments, that 4.5 degrees isn't measured from the top plane, it should be measured from where the involute curve crosses the pitch diameter. So make a point at the intersection, use it and the central axis to define a plane, and then measure the 4.5 off of that. I'm not a big gear guy so correct me if I'm wrong, but doing that will make your tooth thickness and spacing equal

[@silentprayers728]

@@timbarrett4580 I don't get it, make a plane that goes through the point and through the center axis? Then it creates errors Edit: nevermind, thank you!

[@silentprayers728]

@@CADPLMGuy if you create a relation for that how do you use it when making the plane offset? There's no option to use a parameter

[@silentprayers728]

That took me way longer than 18 minutes but it was straight forward! That was my first time using project, I'm not sure I get it but it worked? Thank you.

[@qiangzhang-thingking]

11：36 why the mirror plane is 6 degree？

[@CADPLMGuy]

I had a brain fart.

[@notimportant8643]

Thank you for this, still works in 2023 as of version 9.0

[@anthonyt7756]

Huge help for machine design project!

[@CADPLMGuy]

Glad to hear that!

[@cadinsider964]

I change the Pitch dia in the relation but it doenot updates every thing else automatically. which means it is only for the values for which it is modeled.

[@IceCream_Racing]

Super detailed, thank you from an engineer in sweden

[@CADPLMGuy]

Glad it was helpful!

[@kalaivanansvkalai5718]

sir,do you have any video to create shaft spline inner and outer?

[@CADPLMGuy]

No.

[@viralagricultureworks1710]

Sir, how to calculate the angle of involute curve for mirror the curve???

[@CADPLMGuy]

I know I got it wrong in one of my videos. It should be 360 / (number of teeth * 4).

[@viralagricultureworks1710]

Thanks Dave sir.. Your video is provide completely different knowledge about Creo to another video.

[@stanbillington814]

How do you make the gear that this one mates with?

[@alirezaahmadi6043]

How can i scaling my gears by these Equations?

[@rbffr]

What is that 6 degree it is fixed for every dimension or different

[@CADPLMGuy]

I previously wrote that’s a math error.

[@安田くうきよめ海外]

Thank you very much. It’s very simple and clear teaching video.

[@shivamagarwal9084]

my curve gets formed in the top plane ..even though i followed all these steps..can somebody help?

[@Sagar_Patel975]

THANKS SIR ITS REALLY NEW FOR ME

[@cadinsider964]

very nice man. Wish you had shown the result by changing the parameters in the last and to how it updates. i am going to creat one based on this tutorial.

[@ihatem2970]

Dear Dave Martin- what is the correct way to reference my big assembly to a family table reference part? For example: I have a ring with different sizes and thicknesses (family table ring) , I want to build my big assembly (or is it skeleton?)to reference that family table ring, so that my assembly will change based on which ring I choose from my ring family table. Should I use the ring as a reference or- should it be done in skeleton or do I create family tables of my assemblies in my assembly? Best regards Henrik

[@esrAsnataS]

Great tutorial, thanks. I don't even need to design gears :)

[@CADPLMGuy]

Thanks!

[@silentprayers728]

Your planes have the name of the plane right beside them. How do you get creo to do that?

[@CADPLMGuy]

Just turn on the display of the plane tags from the View tab.

[@saadamiens]

This is awesome, can you please do the same tutorial on spiral bevel gears - thanks again

[@CADPLMGuy]

I don't have a geometric method for constructing a spiral bevel gear. If you are aware of one, please point me in that direction.

[@ROHIT-s1o5x]

Hi sir.. Thanks Your all videos are very helpful for new comers. Please also make videos on all type of sectioning and how to study drawings easily.

[@ouedzul]

What is the difference between creo and solidworks?

[@CADPLMGuy]

You should watch my Creo Parametric-SolidWorks comparison videos.

[@rukminisrikantrevuru6663]

In the last step of writing a relation for pattern, the angle between members needs a relation too. angle = 360/teeth. Else, you will always get just 4 teeth.

[@spiekj]

thank you very much i will have a stantard gear to use. For information the shape of teeth it could be better that the symetric plane will pass thrue a point onto the Pitch diameter separate by a distance of a pitch p/4 to use the pitch formula p=pi*m.

[@dominiquenicolle67]

Very great, thank you so much

[@lolovq7837]

Is this the same guy that narrates Donut Media's podcast?

[@CADPLMGuy]

Is who the same guy?

[@cadinsider964]

The tooth width should be parametric. and this is not correct here. It should be like 360/80. i.e each tooh has 2 times of that mirror angle and then there are 2 time of mating teeths. so for 20 teeth it should be 2*20*2=80 such angles of mirrors in a 360 rotation which is 4.5 for one teeth.

[@CADPLMGuy]

You are correct. I realized that after I published the video. I mention the error in a subsequent video.

[@MACROPARTICLE]

Nice, but this method has too many steps involved.

[@CADPLMGuy]

No one is forcing you to use it. I look forward to seeing your video on the subject.

[@MACROPARTICLE]

@@CADPLMGuy I didn't mean it in that context. As someone with only a basic level Creo skill, I would much rather draw the features and perform the calculations manually rather than inputting these parameter values in. That's just my style.

[@CADPLMGuy]

@@MACROPARTICLE If you research the physics and mechanics involved in gear design, you will find that you cannot simply just draw the feature. This method does not deliberately use a more complicated technique than necessary. In fact, it actually approximates the necessary geometry for a constant pressure angle. I've recently been working on a method using Mathcad that creates more accurate geometry for gear design. Unfortunately the physics of the real world do not change based on our CAD skill level.

[@yipper503]

@@CADPLMGuy Hi. Great video. I'm a long time Creo user and know it's both powerful and sometimes unnecessarily complicated. I feel like this process leans heavily towards the unnecessarily complicated side (not your fault, of course). I'm just learning to use Fusion 360 and it has a built in gear generator feature. Just enter a few parameters and the gear magically appears! I was thinking I would just build my gears there and import the step models into creo for use with the rest of my assembly. Have you looked at doing something similar and, if so, do you still feel like it's worth building all the relations yourself in creo vs. importing from another modeler?

[@MrDuane-lr8dm]

Any chance of drop boxing this, and other, simple projects you may have? I learn better when I break things. It helps me understand what to do right, when I do things wrong. Thank you kindly. This video is exactly what I was looking for to explain Creo.
