This results in minimal static torque reaction between the hub and the shaft. How did you come up with the tool form to create the drawing you sent to the tooling supplier?
Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. 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. Register now while it’s still free! Go to the link below where you’ll be able to email me with your contact details. In other words, what tolerance or type of fit will you require between the mating parts?
There is no power transmission between the shaft and hub. I though I’d share the follow ups via email on this thread.
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. Do you have a sample shaft? Also if you could, could you draw out a. Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.
If the tool is 20 degrees then the spline should be defined as 20 degrees. 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.
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. I must have typed that wrong. The pressure angle also varies along the involute curve, starting at the base circle all the way to the tip of the tooth. Since there is no power tranmission, the teeth will not be cut, but formed net shape. My guess is that the shaft is made per the class a loose fit.
Inspection of a sample production axle here shows no chamfer on the tooth tip, so the shaft is probably designed for tooth flank fit. I am designing the hub for a sliding fit, so per pg of the JIS B document I sent you, the tolerances are: Download Now White Paper: Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden. My understanding that per the JIS D spec, the PA is 20 deg at the base of the js, and due to the nature of the involute shape, the angle at the dd2001 diameter is 30 deg, where the teeth theoretically meet.
So per pg of the spec, I would classify the fit as “loose” or at best “sliding”.
I’ll then get back in touch with you so as you can send me a copy of the specs. So for the hub, per the table on pgI am assuming the following tolerancing: The reason I ask is that I am also designing a 7mm 7z x 0. Hi – I am trying to design a hub with female splines to fit with a shaft, that has the following splines: Are you an Engineering professional?
Regarding the shaft, I do not have any information on the circular tooth thickness. Regarding the PA, thank you for catching my mistake.
Or maybe someone can be kind enough to create the info for me and post it? Do you have more information on the shaft such as measurement over pins or circular tooth thickness? That would clear things up for them. Click Here to join Eng-Tips and talk with other members!
Thank you for helping keep Eng-Tips Forums free from inappropriate posts. This applies to either female or male splines, correct? In this application, the type of fit can d2001 sliding or clearance type fit.

The generated pressure angle will be different depending on the amount of profile shift or addendum modification. Red Flag This Post Please let us know here why this post is inappropriate.

I have another question about the involute spline standard I sent you. Any thoughts as to how I might have worded my response would be appreciated. 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. JIS D is for automotive splines with 20 deg P.
No amount of profile shift will change the pressure angle at jls base circle.
