What is the equation for converting the circular tooth thickness to chordal tooth thickness. I know it is something simple but I cannot find it or remember what it is. Thanks for any help. Troy

Thanks fo the info. Ash is out of them so I will keep looking.

Thank you for your help. There is some intersting pieces of information in these. Troy

I work in an industry where plain bearings (usually bronze)for low speed high stress applications are used. We have played with both straight grease grooves and helical grease grooves and really cannot see any difference. The straight grooves are much easier to manufacture and therefore more...

I would like to get a copy of the book Involutometry & Trigonometry by Werner F. Vogel. Does anyone have this book and would like to sell it?

Hello desertfox, I was redoing this equation in the other post (javascript:gothread(404,45029)) and noticed I had substituted for Ui with Uo in the last part of the equation. I do not remember if this a typo or something I did because I thought it would look better. I am writing a standard for...

Thanks for the info.

Thank you for the verification. The reasoning behind the torque calculation is the bearing had spun in the bore and now I am trying to get an understanding of what happened so I can size my dowels and new fit. Thanks again.

After researching a while on the internet, thru Mark's, and Roark's I thought I would ask here if my logic is correct. I need to know the torque holding ability of a bushing press fitted into a bore. I can calculate the implied force from the equation Deflection = (P*L)/(A*E), where deflection...

Thanks for the info, this is what I was looking for.

I don't know if you ever got your question answered but if you did could you direct me to the source. We are a job shop that manufactures mining, oil field, and railroad equipment and have been running into quite a few JIS specifications. I have not been able to find a good x-reference.

smitty1322, I do not have this standard but will probably get it ordered. Do you have the equation available? I would really appreciate it if you could give it to me since acquiring the standard will take me some time. Thanks, Troy

I was wondering if anyone could tell me the equation to calculate the circular tooth thickness of an involute spline. The Machinery's Handbook has everything but that.

Thanks for replying but what is ESDU structures?

Does anyone know of any good reference materials for designing pin loaded holes?

To reply to ecampos and stress I used the stress concentration factor from Peterson's Stress Concentration Factors for axial tension in a thread. I tried the FEA model and after the 4 th time it crashed I realized the FEA software I have is pretty lame.<br><br>Don,<br>I tried the material...

Depending on the loading of the slabs/beams the strength will be determined by the strength of the epoxy. you are interested in the bending strength increase. That will be determeined by the shear strength of the joint over the entire section. I believe the proper term is the slip plane.<br>I...

I am designing a drive line that must be threaded. I have a size constraint (maximum)on the diameter that must be used. I have tried to use V-Threads but when I add the stress concentration factor of 2.8 to the calculation my stress is well above allowable. I am looking for stress concentration...

Tom,<br> I have checked a couple of places for the book but can't seem to be able to get it. If you have any info that you could offer please let me know.<br> <br> Troy Allee<br> <A HREF="mailto:troyallee@hotmail.com">troyallee@hotmail.com</A>

I agree withTJW and justajeepr. Blodgett's is not only a good reference but is priced right.
