Shaft coupling

[mainshiptom]

I heard a big bang and thought I damaged my gearbox but on further investigation it looks like its the coupling between the ZF 220A 1 and the shaft which is stainless steel 1 3/4 inch thick has given up.

should i fix or replace with a new coupling (less vibration?),

can anyone recommend a trade that can do that in Kent?

 

[Mr Googler]

Have you got a flexible coupling?

Have you got a flexible coupling?

no its a metal one.

Depending on the size etc you may be able to just buy a new coupling. Doesn't need to be stainless either, just paint it.

Difficult to advise without seeing pictures and understanding what/how failed

So appart from the corrosion on the gearbox flange and on the bolts,, and the broken bonding wire, what is wrong with it? Has the shaft moved relative to the coupling?

Looks like the shaft has slide out a bit
