A useful tool, I used it to check an existing calculation. However it takes a while to understand how to use it. Overall I'd say its good and I'll use again.

I am looking for Rack & pinion gear calculation.how i can use this sheet to get required information.

The program works very well. I will evaluate it a little further before deciding whether to purchase as it appears far in excess of what I need

Dear Sir/Madam,Before buying your software I checked the demo. of your module for spur and helical gears calculations.Unfortunately the only option I found is calculations without errors, means I could not check tolerances/deviations of dimensions over pins subiect to backlash limits or even change backlash in the table and receive result to this data (all data are for \"0\" backlash without any possibility for changes), posibility to modify tooth thickness and get the dimension over oins or span over teeth, entering DIN or ISO or AGMA quality grade and receive tooth errors/deviations etc.In case there ...

We are looking for program to check existing set of gears, unfortunately Spur Gear Calculations 1.16 do not support this type of calculations.Regards,Steve

MITcalc review Your spreadsheets for Metric-ISO gear design are very good. But we badly need a good comprehensive textbook in English. It seems that the only good books are in German. I bought 4 of your gear design spreadsheets.Thanks for your good work.Prof. Hatem Radwan

MITCalc Review It is a quite easy-to-use spreadsheet. The main advantage is that it is like an algorithm; if you follow it step by step, you will end up to a result. Its disadvantage is that it doesn't comply with other standards, like DIN and ISO, and it could be as an option. Nevertheless, it is quite good for solving simple pair of gears, and the results are more than satisfactory. I use it mainly to have a preliminary calculation before I turn to the original AGMA analytical calculations (that is, all the background calculations that the spreadsheet does) or to check ...

nice workveerachari,Design engineer

the program is not working !!!!!

even a bricklayer can.... I hope to enter my 90' Lincoln Mark Vii in the 100 mpg race next year. I needed a way to redesign my AOD transmission for racing and I couldn't get my modeling software to derive the design. MITCalc was easy to figure out, even for this bricklayer. I hope to have the fastest car and contribute to helping America climb out of this economic delima. Check out my progress at w.w.w dot evloansfor dot us

Updation We already bought the MITcalc software an year ago. In that there is no planet gear option. The newly developed is very useful for us. Can we get free update for Mitcalc.

Dear Sir/Madam,My name is Ehsan and I am doing my PhD in electrical engineering. In the direction of my thesis I have to compare the dynamic model of bevel gear with Spur one. I was wondering can you help me in this regard and provide me some information or reference for me.I would appreciate if you could reply back to me.Yours faithfully,Ehsan

I tried Demo version. The softwares developed by you are very useful & handy.

Great program! Easy to use, you get the results really quick. A real lifesaver if you need quick, accurate calculations.
