Connecting the motor to the shredder
I’m just looking to get my project going and keep hitting little walls that I’m struggling to get over. Can anyone give me some advice on this please!
I have acquired this motor free, with a VSD, that has been wired by a friend, to control the output speed. However the motor/gearbox didn’t come with an output shaft and the shredder axe is too small (19mm round vs 26mm keyed).
It may be super basic but can I get some guidance on where to go with this?
New shaft? Coupling? Flexible coupling?
Normally, the axe should be 20mm and not 19mm, measure again to be sure. Then you would need an axe (26mm) with a key insert to put in your gearbox, and on the other side turn it down to 25mm (if you know soeone with a lathe). You can then use this kind of couplings:
Could be 3/4 inch (=19mm), and 1″ =26mm
Maybe try a 3/4″ keyed shaft with a 3/4″ to 1″ adapter sleeve
