Does anybody know where I can get the male dimensions or have them handy to fax a dimensional sheet of the spline. Take a look at thread it may have the answer you need. It icludes charts with all dimensions you need. I highly recommend it tiletype you work with metric splines.
This mimics an earlier posting by gearguru: The spline specification looks like this: This spline is “side fit”; the OD or ID centered splines are described with more data. The root shape flat or full radius can be also specified.
If only one spline is defined, the letter N or W are used before the reference diameter. 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.
In the example above, a bearing with nominal bore size mm will slide above the spline to its journal dia located behind the spline. I would wait for gearguru and let him find the info filetpe you. He must have the specs at work. Thanks for improving my post. Yes, I have the specs at work. I picked the “f8” external spline filethpe a logical meshing spline.
Happy New Year idn everybody who reads this post! The size over rolls applies for the 8f fit only. Note – if both ext. This document explains and teaches the user a lot. Thanks for the post. I am looking for over pin dims for following splines: I’m in the same boat for exactly the same spline detail but don’t have the time to obtain and digest the spec.
Fuletype I’m repeating your origional thread to yourself in the hope you have the answer. I got this data from the hydraulic motor mfg. Take a look at this site. If you print it out it is much clearer. 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.
CIt only changes the clearanc “above” the teeth and makes the internal spline more “pointed”, what can be problem if it carries large torque. 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! 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. You can also check the teeth for shear stress in the middle of the contact area. 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.
