Shims Appplication
Shims Appplication
(OP)
Hello,
My plan is to attach a potentiometer shaft to a gear bore using a shaft retaining compound. The shaft diameter is 0.1248"/0.1245" while the gear bore diameter is 0.126"/0.125", which gives a clearance of 0.0015"/0.0002".
Due to the clearance, I am concerned with keeping the shaft concentric with the gear. I was suggested to use shims in order to correct this issue, and was wondering what the best way would be to use them, and if this would be the best solution?

I'm guessing the bore in the gear will not run nearly that true, depending on the hardware down the line.
A stiff ("rigid") pot support will cause the input shaft to strain against a rigidly held pot.
There are times in life when compliance/flexibility is required.
