Today, we are going to discuss the "Involute Spline JISSD2001 with 20° pressure angle was abolished and integrated into JISB1603.The memo says that it is being
Can't find 20° pressure angle for involute splines So, I will note down where I arrived at after doing a lot of research.
Involute spline reference pressure angle 20° is "JISD2001" of old JIS
Involute splines with a pressure angle of 20° are,JIS D 2001 (Involute Spline for Automotive)" of the former JISIt is.
This standard was mainly used for the coupling of shafts and holes that transmit mechanisms and power for automobilesInvolute spline with involute curve on tooth flanks and no twist However,This standard is now obsolete The first two are the following.
In addition, this spline is not consistent with international standards and should not be used for new designs unless there is a special reason.
If you want to check, you can check it in "Annex to JISB1603".
We may still need to confirm the information.See the Annex to JIS B 1603 for dimensions and other details.
If you do not have a JIS book, you can search for "JIS standards" and view the JIS standards on our website (https://www.jisc.go.jp/app/jis/general/GnrJISSearch.html).
That's it.
