Drive shaft adapter

[garydixon]

I need a drive shaft adapter to increase a 1 3/16 inch round, ¼ inch keyed driveshaft to 1 ½ inch round, 3/8 inch keyed shaft. The adapter would slide over the 1 3/16 shaft and give me a 1 ½ inch shaft.

I can weld two pieces together to fabricate.

Thanks for the help.

Why would you want to do this?
It sounds like you are headed
for a failure unless your loads
are very low.

Thanks for the reply.

I am converting an old tree limb chipper from inoperative gas engine power/pulley/belt to tractor PTO. The shaft on the chipper is 1 3/16 inch and the available PTO adapters to round keyed shaft are in 1/8 inch increments from 1 inch to 1 1/2 inch. Yes, there will be quite a bit of torque with large tree limbs.

There is a weldable bare hub available in 1 3/16 inch and I could weld the PTO adapter to that. Do you have a better solution?

Gary,
Sorry to be so dense, but the shaft already
has a keyseat in it and I assume if you add a
circular shim weld it in place and then enlarge
the keyseat to accomodate the wider key it
probably will be ok.
