Involute Spline

This applies to either female or male splines, correct? I though I’d share the follow ups via email on this thread.

No amount of profile shift will change the pressure angle at the base circle. Download Now White Paper: Go to the link below where you’ll be able to email me with your contact details.

So for the hub, per the table on pgI am assuming the following tolerancing: Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.

Hi – I am trying to design a hub with female splines to fit with a shaft, that has the following splines: Also I am considering designing the gear tooth profile without the involute shape, just a straight line, since there is no power being transmitted if I can’t get the involute profile data.

My guess is that the shaft is made per the class a loose fit. Any thoughts as to how I might have worded my response would be appreciated. This results in minimal static torque reaction between the hub and the shaft.

The pressure angle also varies along the involute curve, starting at the base circle all the way to the tip of the tooth. Don’t post your email here or your post will be deleted from the forum.

JIS D is for automotive splines with 20 deg P. Are you an Engineering professional? Do you have a sample shaft?

The generated pressure angle will be different depending on the amount of profile shift or addendum modification. It’s easy to join and it’s free. So per pg of the spec, I would classify the fit as “loose” or jls best “sliding”. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden.

If the tool is 20 degrees then the spline should be defined as 20 degrees. How did you come up with the tool form to create the drawing you sent to the tooling supplier? Inspection of a sample production axle here shows no chamfer on the tooth tip, so the shaft is probably his for tooth flank fit. I sent the tooling drawing to the broach tool maker, he thinks the PA should be 30 deg, but I am assuming he is used to making ANSI spec broaches which probably have a 30 deg PA.

There is mis power transmission between the shaft and hub. I have another question about the involute spline standard I sent you.

My understanding that per the JIS D spec, the PA is 20 deg at the base of the tooth, and due to the nature of the involute shape, the angle at the pitch diameter is 30 deg, where the teeth theoretically meet.

The old “generated vs base pressure angle” problem again. The hub’s function is allow the shaft to be fixed, when removing a mating part off of the end of the shaft threaded end. Regarding the shaft, I do not have any information on the circular tooth thickness.

Thoughts or comments on this? I need to create a 3D model of the hub, so that the “mold” can be made for the powdered metal production tooling. I must have typed that wrong. However the pressure angle at the base circle can not change and in this case must always be 20 degrees, this is the important thing to remember as the base circle is what the involute curve is derived from.
