Or maybe someone can be kind enough to create the info for me and post it? Close this window and log in. Also if you could, could you draw out a. If the tool is 20 degrees then the spline should be defined as 20 degrees. Download Now Defense manufacturing is all about project jix and project accounting.

Are you an Engineering professional? 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 have another question about the involute spline standard I sent you. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. JIS D is for automotive splines with 20 deg P.
d20001 In other words, what tolerance or type of fit will you require between the mating parts? How did you come up with the tool form to create the drawing you sent to the tooling supplier?
The reason I ask is that I am also designing a 7mm 7z x 0. The pressure angle also varies along the involute x2001, starting at the base circle all the way to the tip of the tooth. In this application, the type of fit can be sliding or clearance type fit. Promoting, selling, recruiting, coursework and thesis posting is forbidden.
I’ll then get back in touch with you so as you can send me a copy of the specs.
Since there is no power tranmission, the teeth will not be cut, but formed net shape. Students Click Here Join Us! Join your peers on the Internet’s largest technical engineering professional e2001.

Jiw 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. Do you have a sample shaft? Do you have more information on the shaft such as measurement over pins or circular tooth thickness?

The generated pressure angle will be different depending on the amount of profile shift or addendum modification. This results in minimal static torque reaction between the hub and the shaft. My guess is that the shaft is made per the class a loose fit. Resources 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.

I must have typed that wrong. Hi – I am trying to design a hub with female splines to fit with a shaft, that has the following splines: Regarding the shaft, I do not have any information on the circular tooth thickness.
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. 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 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.
