Tooth thickness

Tooth thickness

Tooth thickness

(OP)
I'm looking at some tooth thickness calculations to check some drawings of synchroniser rings. I know the actual tooth thickness (min and max) and I'm looking for the maximum effective thickness.

I know there are some charts to find it. Does anybody knows where I can find it?

I have an old book on involute splines that refers to the ANSI standard B92.1-1970. I didn't manage to find it on their web site (not even a new version).

RE: Tooth thickness

These calculations are in Machineries
Handbook, at least they are in the 17th
edition.  

RE: Tooth thickness

Hi

UTS Offers software for ANSI standard B92.1-1970. WWW.uts.com

RE: Tooth thickness

Try
 
www.zakgear.com/over_Pins.html
there are 4 pages where you can calculate size over/between pins.

or

www.drgears.com
for info and formulae

UTS is good, but not free. Those two pages are both good and free.

If you need more info, post it here. I have my own programs, in the worst case I can calculate it for you.

RE: Tooth thickness

OOPS!
I reread yur posting. You will need the standard to calculate it.

RE: Tooth thickness

Thanks everybody.

I'm doing my own programs and I think that's a good way to understand all the parameters of a gear design.

I was just struggling with the calculation of the maximum effective thickness. I have found a chart in Machineries Handbook but the result of the calculation does not match with any of the examples I already have (drawings).

I will ask ANSI for the standard.

RE: Tooth thickness

Hey Gearguru that sure is a VERY INTERESTING web site to visit an even thou I have only browsed it very lightly it sure has many interesting different data on gears, been 30+ years on the trade and did not new about it.

Thanks for the very good info.
