Do you have a sample shaft to work from?

JIS D is for automotive splines with 20 deg P. Promoting, selling, recruiting, coursework and thesis posting is forbidden.

I need to create a 3D model of the hub, so that the “mold” can be made for the powdered metal production tooling. D001 per the table on pgthe shaft falls into the class a or “loose” tolerance class. Close this window and log in. Do you have a sample shaft?

Red Flag This Post Please let us know here why this post is inappropriate. The pressure angle also varies along the involute curve, starting at the base circle all the way to the tip of the tooth.

Are you an Engineering professional? Regarding the PA, thank you for uis my mistake.

I am designing the hub for a sliding fit, so per pg of the JIS B document I sent you, the tolerances are: By joining you are opting in to receive e-mail. Download Now White Paper: If the tool is 20 degrees then the spline should be defined as 20 degrees.


I have another question about the involute spline standard I sent you. No amount of profile shift will change the pressure angle at the base circle.

The reason I ask is that I am also designing a 7mm 7z x 0. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. That would clear things up for them. So for the hub, per the table on pgI am assuming the following tolerancing: Go to the link below where you’ll be able to email me with your contact details. 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.

Also if you could, could you draw out a. Regarding the shaft, I do not have any information on the circular tooth thickness. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. Click Here to join Eng-Tips and talk with other members!


There is no power transmission between the shaft and hub. The old “generated vs base pressure angle” problem again. I sent the tooling drawing to the broach tool maker, uis 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.

I must have typed that wrong. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden. The only thing that can change the base pressure angle is the tool used. My guess is that the shaft is made per the class a loose fit.

Digital Transformation may be defined in a jiz of different ways by analysts or enterprise software vendors. If possible can someone point me to a program that can create the spline data for importing into Unigraphics, or a program that can create a.
