Woodruuff Key

[Anonymous]

Anyone knows how to place a woodruff key from the Library onto the shaft? Also, do I need to cut the keyway first? In one attempt I tried to put constrains but it seems impossible! Please help!

Its a breeze using the Mechanical Desktop, surely it can't be that difficult in Inventor!

Your shaft would need to have a keyway.  What I normally
do is constrain the side of the key to the side of the keyway on the shaft and
then I constrain the top of the key with an angular constrain to one of the
origin planes on the shaft.

Thank you Nick, I never thought it was possible to constrain a part to one of the planes. In this case I have a tangent offset plane to the tapered shaft, I should be able to mate the flat surface of the key to that plane and it will be perfect!

Opss, another important thing I'm unsure of is: Does the part library have sizes of keyways (like in Mech. Desktop) so that I can pick and constrain onto the shaft before placing the key. That would eliminate cutting the keyway, if yes then why I can't find the keyways in the library?
I'm using INV 6.

The keys are found under ANSI and GB standards.  The keys
do not display sizes.  You can choose the correct key and then
constrain it with offsets.  Constrain the top of the key to be flush
with the origin plane of the shaft and then put an offset so that it stick out
of the shaft.  Then constrain the side of the key to one of the other
origin planes of the shaft and offset that constraint by half the width of the
key (you choose the key width from the library, so make a note of it when you
choose).   Then edit the shaft from within the assembly and adaptively
cut the keyway to match the key which you have constrained.

Hi Nick,
you can also try to use MechSoft for Inventor. There is very easy to select
key from library, makes calculation and insert keyway as design element by
functionality Insert according to this... .
Or the easist way is to use shaft generator which generates shaft with
keyway and than you insert the key based on parameters from shaft. Task for
30 seconds...

Thanks again Nick, now it's crystal clear. I know that others will find this information useful also! It is not until one needs a woodruff key in an assembly that would stop and think " are they're available from the part library or should I draw one", I guess either way is OK since they're easy to make.
