How to Attach Pulley to Hollow Shaft
How to Attach Pulley to Hollow Shaft
(OP)
Any advise on how to attach a pulley to a hollow shaft?
Background info:
Shaft Material: Steel (exact type not determined)
Pulley Type: Synchronous Belt (14M 6.32" Pitch Diameter, 2000 RPM, 125HP, 315 ft-lbs TQ)
Shaft OD: 50mm
Shaft ID: 40mm
My initial thought is taper lock bushings (2517 Gates). This puts a very high clamp pressure that can crush the shaft. The other is welding, but the shaft materials that we want to use cant be easily be welded.
Any tips/tricks as to how attach said pulley?
Thanks alot.

However, loctite might be a less crushing way of handling this.
I assume you've actually stressed all this and it makes sense?
5mm wall thickness tube is an unusual choice for that job, I'd expect a solid shaft.

How much would a chemical bond like loctite increase the holding power?

You could bottle-bore the shaft, i.e., just make it locally thick enough to deal with the stress from the taper-lock.
