Hello Hacks,


Could u pls send ur gear tutorial file to my email-id: pinnacleuse@yahoo.com


Thanks in advance,

Hello can you send this Power point to ndlight@yahoo.com

In Pro E you can create the involute by equation using Insert Datum Curve

Db=Base Circle


Insert Datum Curve > From Equation>

r=Db/2
ang = t * 90
s = (PI * r * t ) / 2
xc = r * cos(ang)
yc = r * sin(ang)
x = xc + ( s * sin(ang))
y = yc

Why use cartesian coordinates???


Use cilindrical coordinates for both involute curve and path curve over which you sweep the tooth sketch.Then usevariable section sweep.

how hard is to download it from the link that os2man4 posted?


if you don't see the link it doesn't mean it's not there. Look harder.

The PPT looks interesting, but I think a lot of people will give up on the number of equations to derive and the complexity. It can be done a bit simpler with a true involute geometry. My method is based on DIN3960 (don't blame me for being Belgian

).


I have to apologize on my previous posting though. I was a little too fast offering a download location. Apparently, if I would allow people to download the file, I would end up with problems regarding copyright etc etc as the file is intellectual property of the company I work for (although I built it from scratch).


I will try to write a guideline on gear modeling.

Hi


I would be interested in yourppt for the generation of involutes. Please send it to:


rajesh_windz@yahoo.co.in, rajeshwindz@gmail.com-

I can send you a Powerpoint given at the 2005 World Event...

Creating Gears and Splines: 3 Methods for Generating
True Involute Curves

Send me an email.

< = defer>

Perhaps this will shed some light on the matter:

[rajkumarg]

I amnew to proe,i have a problem in drawing involute gear ,i don't know how to draw ?i haveheard that powerpoint presentation for involute gear. Can anybody send me the attachement at mpk_grk@yahoo.co.in





please help me


thanks in advance

Hello,


It wud be better if u attach it in this forum only. Coz i see a lot of us need it.


Anyways if u cant do it... here is my id: ringo80@hotmail.com


Thanks for sharing

 

[Ringo]

Hi


Sorry abt my previous id


Send toringo.1980@hotmail.com


Thanks again

 

[Hacks]

Gents,


There are two links in this thread that take you directly to this presentation,
one on thesecond page and one on the third page of this thread,

[nracingdev]

just wondering if the PPT is still available as both links seem to be dead.

thanks

Hi All


I think this files i receive if i am not mistake.

Hope this files will u all.

I have read thru the response. It seem like the focus is on the active profile of the involute gear. Are you guys doing anything with the Trochoid profile?


The Trochoid Profile is quite difficult when you have 12, 9 or even 7 teeth and "no undercut". It's very difficult to design gears with fewer than 9 teeth and try to get rid of the under cut at the same time.


I spent countless hours trying to automate this process in a different CAD package. I finally got it to work reasonable well. If anyone of you have a need for a true involute gear (spur) active profile + true trochoid profile , I can provide assistance at small fee.


The model I provide can be used for CNC machining, EDM wiring, plunge EDM, STL for rapid prototype. I can provide in STEP, IGES, Parasolid (.x_t), STL, and etc... The model can also be used for design and packaging. I can provide gears in mid-value for quick prototype as well as MMC andLMC for packaging tolerance study.


I am an active member of AGMA committee. I can be reached at: true.involute.gear@gmail.com


Or visit my website at: http://true-involute-gear.comxa.com/ to download a sample of my work.
