Ouch!
The aluminium shear key is supposed to prevent that from happening.
Sorry, I don't know how they come off on the 5" lathes - on the 280 lathes the gear is a slide-fit on the shaft, retained by the shear key and a grub screw in the side. I can't make out what is showing in your picture on the end of the gear.
I expect the only way you will find a replacement is from a machine being broken for spares - but I think we should be able to identify the drawing so you could get a new one made.

HI may not help but my tds11gb has a little grub screw/ keyway and it comes off like that. but i have never see one like yours. take your quadrant and all the gears off the top so you dont harm them! then have a good look and may be get some pullers on it?
