The encoder is still mounted to our gearboxes soundly, its just the coupling between the gearbox shaft and the encoder shaft that the surgical tubing is used.
A. Cost - for four corners its cents for surgical tubing compared to the 15+ dollars per corner for precision couplers.
B. Vibration - the surgical tubing spins the shaft but at the same time limits a lot of the vibration transfer into the encoder generated by the gears and robot moving around.
C. Misalignment - Goes hand 'n hand with vibration. The surgical tubing allows for slight misalignment of the encoder and the output shaft. Where as a precision coupler is not as forgiving. The grayhill encoders are quite durable compared to others but still we want to limit the extra load caused from misalignment
