In the example above, a bearing with nominal bore size mm will slide above the spline to its journal dia located behind the spline. Take a look at thread it may have the answer you need. Increasing the major diameter I believe that is what you call “bore”, that’s what I found in the DIN standard has no impact on the backlash. He must have the specs at work.

You can also check the teeth for shear stress in the middle of the contact area. I am looking for over pin dims for following splines: Din Male Spline Dimensions?

Happy New Year to everybody who reads this post! Join your peers on the Internet’s largest technical engineering professional community. In the past I have worked out strength of gears using the lewis formula, If I apply this to the 11t din spline and multiply the figure by 11 teeth I have 6. If only one spline is defined, the letter N or W are used before the reference diameter.

Thank you for helping keep Eng-Tips Forums free from inappropriate posts. CIt only changes the clearanc “above” the teeth and makes the internal spline more “pointed”, what can be problem if it carries large torque.

The reason for this spline description is to give the designer the information, what size of part most of the time bearing’s bore can be moved with some clearance ABOVE the spline.

It’s easy to join and it’s free. There is a relatively new DIN standard for doing these calculations; it is complex and I did not see any splines checked by it yet – but it does not mean that some people are doing it.

I highly recommend it if you work fileype metric splines. The root shape flat or full radius can be also specified. I’m in the same boat for exactly the same spline detail but don’t have the time to obtain and digest the spec.

Please wait…

vin This spline is “side fit”; the OD or ID centered splines are described with more data. I got this data from the 54800 motor mfg.

It does not have any impact on the fit my previous posting is valid herebut you are also making the contact area between the teeth smaller, therefore you increase the contact stress on the tooth flanks.

Sorry for my mistake above! Thanks for the post. If you print it out it is much clearer. I would wait for gearguru and let him find the info for you. I’m looking for male spline dimensions to make a shaft to fit a din female spline Nx5x30x38x9H.
