self aligning/mating shaft coupling

Dec 06, 2006 3 Replies

Hi People,



I'm looking for a shaft coupling that will automatically align when a removable component is placed onto our unit. (So the shafts can be 'out of phase' while connecting )



At the moment I'm using a spider coupling with a rubber mating grommet (shaped like an 'X'), which sometimes needs a bit of help, otherwise the rubber can get pinched and the component won't sit correctly.



I guess an example is a blender: Put the jug on the base unit and press start. Nothing else needed. (except of course a mop and cloth because you forgot the lid.)



A blender drive isn't reversible however.



I'd strongly prefer to use a ready made component - I've checked through most of the major catalogs, and haven't seen anything ideal. If anyone has any ideas, I'd love to know.



Cheers Marc


--Sounds like you need a Lovejoy coupling. Try an automotove or bearing house.

You might also consider an Oldham coupler.

But I think you would be better off trying to get the shafts more concentric.

The blenders that I have seen all have some type of shroud that forces the two shafts into alignment.
