<p>A tuned damper for the input shaft on a rotary encoder includes a mounting plate and a mass plate having a plurality of mounting flanges each having mounting apertures. Fastening elements couple the mass plate to the mounting plate, and resilient elements or donuts each having a central aperture are positioned on either side of each mounting flange. The diameter of the fastening elements is smaller than the diameter of the mounting apertures and the holes in the resilient donuts so that the fastening elements do not touch the body of either the resilient elements or the mounting flange and the mass plate does not directly contact the mounting plate in order to isolate the mass plate from the mounting plate. The mass plate dampens torsional vibration which may exist in the input shaft of the encoder.</p> |
