QUICK LOCKING SHAFT MECHANISM

[diasmanuel]

Hi all,

I need help. I need to design a machine for testing electrical motors.
The problem is how to attach a motor that has a round shaft to the tester Machine, and in between there is coupling to compensate alignment errors ?

A collet sistem can not be installed because there is no hole on the main Arbor that could be used for feeding air or oil.

I tried a sprag clutch bearing .It works but it needs a hammer to unlock the system and that could damage the either the motor or machine bearings.

Any ideas ?

We also use a chuck similar to the ones in the reference posted by williedawg. We use that type of chuck with rubber collets for a quick grip and release.

Make sure any device that transfers the torque via friction (like a collet or clamp) can generate enough friction to produce the torque you need.
