Spring loaded dog clutch

Thanks to one and all for your comments. The gear ( aka what I would call a dog clutch) is certainly the one pictured above. It's function would be to prevent damage to the other gears and motor should there be an overload, like little hands stopping wheels from turning. Fusing the two gears together or replacing them with a single cog would work in theory but it may cause damage elsewhere later on. I guess that is a compromise one has to consider.
Should I come up with a viable repair alternative I will post it on the forum.

Cheers
