Find the most up-to-date version of JIS D at Engineering Hi – I am trying to design a hub with female splines to fit with a shaft, that has the following splines: [u]Axle Info[/u] * Spline Std = JIS D In Design Accelerator’s Involute Splines Connection Generator are Japanese Standards missing. Please add JIS D (Involute spline for.

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.
So for the hub, per the table on pgI am assuming the following tolerancing: 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.
Any thoughts as to how I might have worded my response would jid appreciated. Regarding the shaft, I do not have any information on the circular tooth thickness. Close this window and log in.

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 2d001, where the teeth theoretically meet.
The hub’s function is allow the shaft to be jiis, when removing a mating part off of the end of the shaft threaded end.
In this application, the type of fit can be sliding or clearance type fit. This applies to either female or male jix, correct? In other words, what tolerance or type of fit will you require between the mating parts? The only thing that can change the base pressure angle is the tool used.
So per pg of the spec, I would classify the fit as “loose” or at best “sliding”. That would clear things up for them.
The pressure angle also varies along the involute curve, starting at the base circle all the way to the tip of the tooth. I need to s2001 a 3D model of the hub, so that the “mold” can be made for the powdered metal production tooling. Since there is no power tranmission, the teeth will not be cut, but formed net shape.

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 no power transmission between the shaft and hub. Students Click Here Join Us! Regarding the PA, thank you for catching my mistake.
