Need drive shaft adapter
Need drive shaft adapter
(OP)
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.
Where might I find the adapter? I do not mind welding two or more pieces together to fabricate the adapter.
Thanks for the help.

1. Find a good machine shop.
2. Ask them to take a shaft of 1.500 T&G (Turned and ground usually to +0.0000-0.0005 specs) of whatever length you need.
3. Bore out the shaft to fit (most probably to 1.1875 +0.003/+0.0015)
4. Take a 3/8" wide key of the required length. The actual depth of the key may be different than standard and will depend upon choices made in step six. You will need to machine some form of step key.
5. Make sure the key is still straight as the machining will make the material want to bow because of stress imbalances.
6. Broach the collar to accept the 3/8" key. You may wish to mill out the slot. Either method will have its challenges.
7. Install.
This should be doable in about 3 - 4 hours of shop time depending upon your requested accuracies.
If you have some length to play with (at least 3 inches I would think). make a stepped stub shaft where the slide over part on the 1.1875 is of a greater dia. than 1.5" and then change diameter to the required (probably over 1.5 inches or with a large radius using a step). Broach as normal.
