Random elastomer cushion rings for a chain sprocket
Patent No. 8,202,185
Issued: June 19, 2012
Inventor: Haesloop; J. Christian (Ithaca, NY)
A sprocket includes a plurality of teeth spaced about its periphery, roots located between pairs of adjacent teeth, and a cushion ring contacted by a chain engaging the sprocket teeth. The roots have root radii defined as the distance between the center of sprocket and the point along the root closest to the sprocket center in the radial direction. In some embodiments, the roots have three distinct radii. The cushioning material of the cushion ring receives the impact while engaging the chain. In some embodiments, the cushion ring has a contour substantially following the contours of the sprocket teeth geometry. In some embodiments, the cushion ring has a randomized contour to provide predetermined cushioning that varies from tooth to tooth around the sprocket.
