Vibration Issue from Shaft Alignment
Vibration Issue from Shaft Alignment
(OP)
I have a direct drive motor application and am getting alot of vibration from the misalignment of the output shaft.
This is for a high volume production product so I won't be using any precision components. The system needs to be robust enough to handle some generous tolerances.
I am looking at anti-vibration mounts for the motor and/or a self-aligning shaft coupler for the output shaft. Can you give me some ideas on where to find some inexpensive, easily packaged in a small environment, components that will suit this application.

How generous is "generous tolerances"? Magnetic couplings can handle up to around 0.1" of offset.

The "generous tolerances" I speak of will be a combination of concentricity as well as angularity for the shaft alignment.
I'm looking at about 0.2mm tolerances on all features and am not sure of the final stack-up quite yet. My best guess would be max. of about 0.025" offset and 5 degrees.
